Design
Kunikazu is a bespectacled older man who wears a business suit and an orange and brown checkerboard ascot under a white shirt.

Shadow Kunikazu wears a mostly black, form-fitting spacesuit with the same colors as his undershirt, and has turquoise skin. Unlike most bosses, he does not have a demon form as Mammon; he instead calls out a floating chair before radioing a group of robots to protect him.

Personality
Kunikazu is an ambitious and career-focused professional who is always chasing his next victory. However, for his daughter, his employees and his fellow higher ups, his ambitions come with a complete, deliberate ignorance of the pain he causes to his company or his family. No matter how many scandals Okumura Foods faces due to its poor safety practices and punishing work hours or how obviously unhappy Haru is with his manipulations, Kunikazu refuses to let his nobler passions influence his business, instead behaving as ruthlessly as he feels he must to get ahead in the world. In fact, his Shadow Self admits that he sees nothing wrong with using Haru as a political pawn, as he believes it is mandatory to use whatever means to gain fame for his own profit, and becomes furious when he realizes Haru is "betraying" him with the assistance of the Phantom Thieves of Hearts because she fully realized that she has been used as a political pawn against her own will. His overambitious investments and business ventures led to his death, as not only did he refuse to return to his real self after his defeat to enact his change of heart, the Black Mask promptly finishes him off due to his political campaign being the only obstacle against Shido's path to becoming prime minister.

His Shadow is also quite cowardly, as he has no method of defending himself nor transforming himself into a more powerful demon form. Instead he tries to kill the Thieves by triggering a self-destruct mechanism in his Palace and lures them into a trap once they finally reach him. He then attempts to stall for as long as possible using his cognitive robot workers to delay his defeat and run away. This is emphasized in Persona 5 Royal where his cognition of Haru is nothing but an obedient asset for his path to glory. If everything else fails, he turns her into a robot and uses her as a suicide bomb to damage the party just like the other robot workers. In battle, Shadow Okumura also tends to call the real Haru a mockery of his daughter, indicating that if she didn't want to get sold by him, he would no longer treat her as his daughter.

Despite being a cold and heartless businessman with a feverish pursuit for power, accounts indicate that he was a significantly better person in the past who treated Haru with great care. This side of him was never genuinely shown on-screen however, and was only frequently mentioned in-passing. When Haru was young, she felt highly upset for him not arriving to cheer for her on her first sports day because he was busy with work. Big Bang Burger also used to be an honest company that he poured his heart to maintain, instead of the black company it is during the events of the game, indicating that he is nothing more than a man who is corrupted by the seeking of power beyond all belief. As he didn't see Haru as an asset for gaining power prior to the events of the game, she is actually traumatized and guilt ridden when his mental shutdown is broadcast on screen. Furthermore, Mariko Hyodo, one of his business partners and also a friend of Haru, acknowledges that Okumura did genuinely care for her, as the three used to play golf together. Hyodo expresses her condolences to Haru for his passing and when her Shadow Self is defeated, states that he would have been proud to see her growth. Additionally, in the context of Japanese societies, arranged marriage itself is acceptable, although the man that Okumura arranged for Haru is a loathsome playboy who treats her as a sexual plaything, however the Cognition he generates of Sugimura demonstrates that he was aware of this side of the suitor he picked for Haru.

Haru's cognition of him, as seen by Takuto Maruki's actualization in Royal, is of a clumsy businessman who has no interest in politics. He is also a genuinely caring parent towards her, to the point where he comes across as rather overprotective. Should the protagonist eavesdrop on him in Shibuya's Big Bang Burger branch in February, he used to care for his employees' well-being more than the profit of his business ventures. This represents Haru's desire for him to return to a former, non-corrupt, and non-maligantly ambitious state.

He is also somewhat immature in his tastes, as the Big Bang Burger chain is inspired by a model kit he loved as a boy, but could never afford until he achieved success and paid off his own father's loans.

Persona 5
Kunikazu Okumura is the third president of Okumura Foods, preceded by his father. He founded Big Bang Burger, a fast food chain that the protagonist can shop in during his free time.

Kunikazu only has one child, his daughter Haru Okumura. Both Kunikazu himself and Haru, as well as other associates of Okumura Foods had mutually admitted that he used to genuinely care for her in spite of his rather unethical and overambitious business practices, up until he attempts to arrange a marriage for her with Sugimura, an abusive man who does not treat her as anything other than "a plaything" for the sole reason of trying to compete with Masayoshi Shido for the premiership. Even then, it was later revealed that the arranged marriage contract between Haru and Sugimura was fabricated and even some high executives within his company had never heard of it. Presumably, he forged the contract under one of the black box meetings that he frequently held with board members who were loyal to him.

He is one of the heist targets of the Phantom Thieves of Hearts at his own Palace. Initially, Proescutor Sae Niijima notices Okumura's fast food business heavily benefits from his rivals' deaths from the mysterious mental shutdowns and psychotic breakdowns carried out by the Shido's antisocial force, a fact that is learned by the thieves after they have stolen the investigation documents from Sae's laptop. After the Medjed incident, Okumura's heist request ranking in the Phantom Aficionado Website suddenly surges with loads of comments against his business practices. The Phantom Thieves are initially indecisive about reforming Okumura, but settle down when Haru joins them to escape her doomed marriage.

His sin, his Greed, and his Palace is a spaceport formed from his desire for success, to the point where he refuses to acknowledge how much he is hurting Haru or his employees with his overly ambitious business and political ventures. He knows full well what kind of person Haru's fiancé Sugimura is, but arranges the marriage anyway to gain power to become prime minister. The main inhabitants of his Palace are the cognitive existences of his workers, which take the form of robots who are devoted to him and are devoid of any emotion, symbolizing that he views his workers as dispensable labor. The robots are also used to fuel the spaceport when they go defunct, indicating that he considers his workers as easily disposed.

After he receives the calling card, he sends it to the police. When the Phantom Thieves arrive to take his Treasure on the upcoming day, his Shadow activates a 10-minute self-destruct timer in his Palace in an attempt to kill the Thieves in an explosion while he escapes to "utopia," the political world. Once the party reaches him, he pretends to have already reformed in an attempt to subdue the Phantom Thieves by tricking them into separating from Haru and capturing the rest. He then offers Morgana the chance to escape with him, offering him money and fame. He was oblivious to the fact that Morgana had no intention of doing so, as unlike to him, Morgana's allies are irreplacable, who then uses his slingshot to disarm Okumura of his remote, freeing the party. Okumura then proceeds to fight the thieves, believing he has sufficient time to do so. During his boss fight, he sits on a floating chair and summons multiple waves of his robots to attack the party. Recognizing that he is not nearly strong enough to beat the Phantom Thieves directly, he activates a thirty-minute self-destruct timer and hangs back while his robots are on the front lines. After the party takes down all of his forces, including his right-hand man Execurobo MDL-ED, Shadow Okumura is left alone, unable to fight off the Thieves and is swiftly brought down.

Because he is shown to genuinely care about Haru and regularly feels deeply conflicted about his obligation to his business and his daughter, the Phantom Thieves come to respect him as an opponent. When his Treasure is stolen, he attempts to reveal the identity of the head of the group that is behind the mental shutdowns, but the Thieves are forced to retreat because of the tight time limit. When the Shadow Self is left alone, Goro Akechi shoots and kills it. Even in death, Shadow Okumura couldn't let go of his utopia, and was never able to return to his real self.

His Treasure is a spaceship model kit that takes the form of a glowing orb with a metallic shell in the Metaverse, and the appearance of his Palace is based on this model kit. Kunikazu wanted this model kit when he was young, and it is now a valuable collectible. The Thieves sell it to celebrate at Tokyo Destinyland.



During his press conference of October 11th, Okumura admits his maltreatment of his employees, but just as he is about to reveal the true culprit behind the mental shutdowns, he suddenly suffers a heart attack-like affliction and dies on camera, much to the horror of the Phantom Thieves; the general public, however, are initially delighted by his death, but by the next day (right after Igor delivers a congratulatory speech and a warning to the protagonist,) the public has suddenly turned on the Phantom Thieves, believing that they are murderers worth a 30 million yen bounty on their heads. His death, supported by the calling card he had sent to the police as well as the sudden discovery of a calling card sent to Principal Kobayakawa (who's another victim of a mental shutdown) results in a sharp decline in support for the Phantom Thieves.

Haru is left traumatized and guilt-ridden over his death, as in spite of him blatantly using Haru as a bargaining chip, he was still her beloved parent because he used to treat Haru like a daughter, and she vows to uncover the truth behind his murder. Therefore, she also believes that she and her fellow Phantom Thieves are innocent over his death. Takamura also replaces him as acting president of Okumura Foods until Haru could take the role.

When the Phantom Thieves infiltrate Shido's Palace, they find out that his heist request was rigged by the Antisocial Force in order to lure the Phantom Thieves into a trap so that they can be framed for his murder. The person behind it was also the same person behind the blank Medjed threats that kickstarted the heist on Futaba Sakura. Masayoshi Shido also wanted him to be removed from the get-go, as he posed a threat against him during the general election. Despite Shido having ordered the TV Station President to cover up as many of his scandals as possible in gratitude for his funds, the constant scandals that Okumura and his company were often tangled in rendered them impossible to cover up by the Antisocial Force despite protection from the media. When combined with Okumura actually getting into Shido's way of premiership, this made him an incredibly lucrative target to remove alongside the Phantom Thieves. When confronted by Haru however, Shadow Shido has no real recollection of this incident despite it occurring very recently merely dismissing him as an insignificant roadblock to be crushed on his way to power. After the Phantom Thieves change his heart, following his landslide victory, Shido publicly confesses to being the one responsible for Okumura's murder.

Persona 5 Royal
Okumura's role is largely identical in the original game. This time, his cognition of Haru appears in his Palace. Cognitive Haru is depicted as an obedient asset that acts as a part of his movement animation. His support skills also tend to make the battle more erratic than in Persona 5 and the robots flee and reset after two turns (which his movements capitalize on), making the timer a bigger risk. After the party defeats the MDL-ED Execurobo, he dispatches cognitive Haru as a last-ditch attempt to dispose of the party, transforming her into a robot that self-destructs after two turns. Once Cognitive Haru is sacrificed, he is rendered helpless exactly like in the original game.

Taking Back Reality
Okumura is first mentioned in the third term semester by Haru during, when she says they'll be spending time together. He is then personally seen a week later alongside Haru in Kichijoji, scouting for locations for a new Big Bang Burger restaurant. He is now heavily implied to be what he was prior to arranging Haru's marriage to Sugimura for the sake of politically competing with Shido; a clumsy and unambitious businessman who genuinely cares for his daughter. This is an alteration made by Takuto Maruki, who warped history so that in this reality, he never died nor did his political and corporate ambitions rise to destructive levels. Once Haru chooses to deny Maruki's reality, Okumura vanishes.

Before the protagonist checks on all his teammates, Okumura can be seen discussing business affairs with Takakura in Shibuya. This Okumura also personally inspects his branches for flaws and cares for his employees' well being, instead of being obsessed with pure profit.

If the protagonist cuts a deal with Maruki to let him overwrite the current reality, Okumura will be seen spending time with Haru outside a Big Bang Burger restaurant during the credits.

Persona 5 Strikers
While Okumura does not directly appear, he plays a role in one of the sub-stories in the game.

As the Phantom Thieves are sent to Sapporo to deal with another mass Change of Heart incident, they meet Mariko Hyodo, one of Kunikazu's former trade clients. She gives her condolences to Haru for his passing, revealing that they had all gone to play golf together and that she knew he had cared for Haru in her childhood.

Strategy
Before starting the fight, it is recommended to stock up on around 20 revival items, many of which can be bought at Takemi Medical Clinic, since many party members will likely be knocked down during the fight several times. Torimeshi Rations and Yakisoba Pans are also recommended, just don't use them if Big Bang Challenge is about to be used. It is also important to try to conserve SP since there's a chance everyone may run out at the end. Haru's Triple Down skill is quite useful, even though all the robots resist Gun attacks.

This battle has a special condition where the battle must be finished in 30 real-time minutes. Thus, it is best not to spend too much time overthinking commands or listening to the dialogue in battle.

This battle is not directly facing Shadow Okumura himself, but rather several waves of Corporobo minions. The player must defeat all Corporobo minions in order to directly attack Shadow Okumura and end the fight. No more than four Corporobo minions will be present on the field and once one wave has been defeated, the next wave is immediately deployed. If Okumura gets a turn, he will deploy new minions to fill in the ranks. Even though it is possible to knock down all of the Corporobos, All-out Attacks are not possible as Shadow Okumura is technically an active member on the enemy team, just untargetable.

Using Baton Passes are key to quickly move through each wave. Having the Star Confidant with Hifumi Togo established before this fight makes the fight easier as each Corporobo has two specific weaknesses while resisting all others. Having the ability to switch out allies to respond to each new type helps to speed up the fight. The starting party should be based on one's access to Koma Sabaki/Togo System. If it's obtained, starting with Ann and Morgana will help focus on the starting Corporobo types while the third slot can be either Yusuke or Haru, who will give an early set up for when the second Corporobo types appear. Continue switching out to whatever the new Corporobo weakness is until the final phase is reached. If the Star Confidant has not been established, ensure that at least one battling member can cover a weakness of each Corporobo. Ideally, Morgana and Haru should be included as Morgana deals with the first and fourth wave while Haru deals with the second and fifth wave. The third party member can be either Ryuji or Makoto to handle the third wave. In either method, it is recommended that the protagonist carry Personas that have Wind, Psy and Elec/Nuke skills to match his teammates and keep the Baton Passes continuing.

Shadow Okumura starts off with four Corporobo MDL-WKRs. They are weak to both Wind and Fire, so make sure that Morgana or Ann are present at the start of battle. Shadow Okumura will summon 10 of these in total. Once the tenth Corporobo MDL-WKR has appeared, he will begin deploying Corporobo MDL-CH, who is weak to Ice and Psy skills. Yusuke and Haru are incredibly useful for taking these Corporobos down. Once the fifth Corporobo MDL-CH has appeared, he will begin deploying Corporobo MLD-AM, who are weak to Electric and Nuclear skills, so having Ryuji and Makoto out during this phase speeds things up. Once the fourth Corporobo MDL-AM has appeared, he will deploy Corporobo MDL-DM.

Corporobo MDL-DM starts the second phase of this fight as Okumura begins using new tactics. Okumura will begin using a Sacrifice Order command, causing a Corporobo to self-destruct, dealing massive damage to your party, but also killing the Corporobo as well. Your only options are to either quickly defeat the Corporobo targeted by this command before its next turn, or guard and mitigate the damage. Shadow Okumura will also begin inflicting Famine's Breath, causing Hunger on one of your allies, severely reducing their damage output for three turns. Corporobo MDL-DM are weak to Wind and Bless, so Morgana is effective for this phase. Once the third Corporobo MDL-DM has been defeated, he summons Corporobo MDL-GMs who are weak to Curse and Psy so Haru is good for this phase.



After the second and final Corporobo MDL-GM is defeated, the final phase of this fight starts with the Execurobo MDL-ED. The Execurobo has no weakness, but also no resistances, thus the fight becomes a slugfest from here on out. It is recommended to favor physical or gun skills (such as Haru's Triple Down instead of Psio, or Yusuke's Tempest Slash instead of Bufula), especially if Makarakarn is active on MDL-ED. If Haru is in the party, the Execurobo has a strong preference for targeting her. Since it tends to favor physical attacks, having Haru defend herself with Tetrakarn (if nothing else is being telegraphed) is a good way to keep her alive and inflict damage back at Execurobo. Okumura continues to use Famine's Breath and occasionally Famine's Scream which inflicts Hunger on all allies, and he may also debuff these allies or use Dekaja, so if you're low on SP, it is not wise to use party-wide buffs constantly (although buffing party-wide Defense before Big Bang Challenge should be fine.)

Execurobo has a dangerous attack called Big Bang Challenge, which inflicts massive damage on all party members. Thankfully, this move is telegraphed by Big Bang Order the turn before he uses it, so guarding before he executes this move will reduce the damage. Big Bang Order is actually a form of Concentrate, so the upcoming Big Bang Challenge will always hit with greatly increased damage. Additionally, if an ally is inflicted with Hunger during the turn this move is executed, they will instead be healed and the Hunger status removed, so this ally may attack or use a turn instead of guarding. If the Execurobo uses Big Bang Challenge and Okumura casts Famine's Scream in the same turn, do not cure any Hungry party members because it fully heals anyone with the status. Unfortunately, if an ally's Confidant has reached Rank 6, they may remove Hunger with Harisen Recovery. Nothing can be done about this, as delaying a Confidant isn't recommended, though it should not be a major issue. Big Bang Order will also always be used immediately after each instance of boss dialogue during this phase of the fight.

Near the end of the fight, Execurobo will use Big Bang Challenge more often, meaning the player must try to find a strategy to defeat it as soon as possible. If an ally doesn't have enough HP to survive Big Bang Challenge even while guarding, the player should make the most of their abilities and revive them after they are knocked out.

Once the Execurobo is defeated, Shadow Okumura is forced onto the field as he has run out of allies. At this point, he no longer has the strength to fight back and can be taken down after just a few physical attacks. If he does get any turns, he will waste them hesitating.

Persona 5 Royal
Okumura is significantly harder in Royal. While he summons all of the Corporobos of each rank in one wave rather than destroying a specific amount, they will flee from stress if they are not taken down in two turns. If the robots leave this way, Okumura will become annoyed and summon a fresh batch, effectively resetting the wave. The fight will still progress as normal if the last Corporobo destroys itself via Sacrifice Order. All other basics during this fight, such as Baton Pass and not curing Hunger right before Execurobo casts Big Bang Challenge, still apply.

Temporarily adjusting the difficulty to Merciless will increase the damage dealt by striking weaknesses, allowing the robots to be dispatched much faster, although the protagonist should prepare Personas with physical resistances or immunities in case of a Critical hit, which isn't uncommon with the stronger robots and is likely lethal at this stage in the game. Alternatively, lowering the difficulty to Easy or Safety will obviously make the robots more conventionally easy to defeat.

Haru is highly recommended to be in the team for this battle, as she is the only way to reliably damage the MDL-GM robots bar the protagonist and functions as a great damage source against the Execurobo using Tetrakarn. Furthermore, her Triple Down is incredibly useful in this fight with the enemies no longer having Gun resistance, and she can reduce the odds of party members getting inflicted with Hunger using her trait. Morgana is also a good choice, for dealing with the MDL-DMs and his ability to cure Hunger with Me Patra. Hifumi Togo's Rank 1 Confidant ability that allows the protagonist to switch out active party members on his turn in battle is incredibly helpful in this fight, as it allows any battle strategy to be much more flexible. Any Curse or Psy users should be equipped with a Night Necklace or Psy Necklace purchasable for 40,000 yen each in Kichijoji, if possible. Personas with powerful Gun, Psy or Curse attacks, as well as Dekaja or Marakunda, are near mandatory as otherwise the MDL-GMs are very difficult to kill within two turns. Baptismal Water, purchasable for 1,000 yen from the Kanda Church, as well as at least six Psycho/Curse Bombs, are strongly recommended in case important party members or the protagonist are not immediately available for these purposes. Playing billiards and darts in Kichijoji can also rank up Technical and Baton Pass damage respectively. Torimeshi Rations and Yakisoba Pans are still useful, just like in the original Persona 5, to combat Hunger. Torimeshi Rations, however, only appear until August 14th, so it's recommended to stock up on those beforehand.

Do not attempt to chip down the robots with resisted attacks even on party members that can't be used for offense on that phase (unless to squeeze out a stray robot's last bit of HP), because they will barely even scrape the robots and can potentially waste valuable movement slots that could otherwised be used for buffs, debuffs or starting Baton Pass chains using elemental bombs.

All of the robots, including the Execurobo, are also now vulnerable to Freeze, Shock, Forget, Rage, and Dizzy, which can facilitate huge amounts of Technical damage with Physical, Gun, or Psy skills, especially when combined with Baton Pass. Therefore, skills and items that can inflict these conditions are strongly recommended and can significantly swing the fight in the player's favor. The robots still retain the same weaknesses as in the original, although the tubes they're deployed from immediately highlight their weakness to the player.

Okumura will also order all of his robots to attack a single party member individually: four MDL-GMs using Megaton Raid on the protagonist at the same time is most likely lethal. Therefore, try to make at least one of the protagonist's Personas resists, or even better, nulls or repels Physical attacks. Okumura will not shift targets until he and his robots get their turns. The only exception to this is if the protagonist switches out the targeted party member using Hifumi's Confidant ability. In this case, the first robot will squander its turn being unable to locate its target, after which Okumura will express distaste at such an "underhanded move" and order a new target for the remainder of the round.

After defeating the third wave of robots, Okumura can cast Rakukaja on a robot, followed by a Rakunda, Dekaja or Famine's Scream on the party. This is telegraphed by him receiving mindless encouragement from the cognitive version of Haru that assists him in the battle. When this happens, be prepared to cure Hunger and use Dekunda/Marakukaja on the party and Dekaja/Marakunda on the robots. If Okumura gets a turn after this, he will issue a sacrifice order on one robot. If one is lucky, he will start with just one Sacrifice Order, which actually makes things much easier as this means Haru or the protagonist can wipe out all robots with a few Psy or Curse skills within the two turn window. In the worst-case scenario of Okumura using Rakukaja and then Sacrifice Order on the same robot, be prepared to forfeit the chance at clearing that wave of enemies, because it is highly unlikely to defeat the affected robot in one turn without focusing attacks, and in most difficulties a Sacrifice Order will be very lethal.

It can be an effective strategy to keep a lone robot with a sacrifice order placed on it alive and guard, as Okumura will immediately shift to the next wave if a robot self-destructs and there are no other robots on screen. It is advised to heal after this.

MDL-GM robots are the biggest roadblocks in this fight, as it is extremely difficult to kill all four within a 2-turn window without any setup. The first priority of any round should always be removing Rakukaja cast on any of these robots immediately, as these robots with a defense buff are almost always impossible to kill within a 2-turn window. In order to prevent this, use Baptismal Water or Dekaja to remove the defense buff immediately, and use a Hunger curing item to remove Hunger if the protagonist or Haru is hit with it. If one has a Persona with Marakunda, consider that instead since it both cancels the defense buff and makes all other robots easier to kill. Rakukaja may also be used on MDL-DM robots, however, they are much easier to deal with, so it isn't as critical to remove.

To take down the MDL-GM robots, the following procedure is the most optimal:
 * Dekaja/Marakunda/Baptismal Water on the first move to remove Rakukaja from a robot.
 * Next member should use a Psycho Bomb or Curse Bomb on one GM, then Baton Pass to another party member, and use another of the same item to knock down a different robot.
 * Haru should use a single Mapsio to down the final two robots and damage the two that were already knocked down before Baton Passing to the protagonist.
 * The protagonist will have a level 4 Baton Pass, which allows his moves to be used for no cost and, more importantly, grants the highest damage bonus. Use a multi-target Psy attack or Triple Down to deal massive damage to all robots on screen.

Plan carefully when using multi-target moves against the MDL-DM and MDL-GM robots, because when used carelessly, they may knock down all the robots prematurely, removing the opportunity for any further Baton Passing.

The Execurobo retains the same features as his Persona 5 counterpart and unlike the previous five waves, there are no turn limits in defeating it. However, the timer still remains an ever-present threat. Furthermore, Okumura can use all the same support abilities he had access to in the previous waves, so the Execurobo's defense can be buffed by Rakukaja, and Rakunda becomes a threat as it allows the Execurobo to potentially kill party members with Big Bang Challenge outright, even if they guard, especially on Hard mode or higher. While time is more lenient here, it's still recommended to remove the buffs or debuffs while possible, otherwise the robot will become very difficult to kill and the Execurobo might kill party members every turn. As stated previously, Haru's Tetrakarn is highly useful against it, as are ailments, as they allow Technical damage and prevent the Execurobo from starting Big Bang Challenge for a duration while Frozen, Shocked, or inflicted with Forgetfulness. However, Rage does not work on the Execurobo.

After defeating the MDL-ED robot, he will send Cognitive Haru as a last stand. While she can only use regular attacks that do around measly damage, Okumura will use Sacrifice Order on her after two turns have passed. Cognitive Haru's self-destruct deals massive damage and despite Haru's suggestion to destroy it, it is unlikely the player will be able to do so. Instead, heal up and guard the incoming attack; using Marakukaja beforehand is helpful, but not needed.

As long as one character survives the self-destruct, Okumura will become shocked at Cognitive Haru's failure to take the Thieves down. Unlike the original game, Okumura in Royal only has 1 health and will be taken down in one hit.

Stats

 * The boss has a time limit of 30 minutes. If the player does not defeat him in time, it will trigger a unique game over cutscene.
 * The timer will continuously go down unless in the Persona selection screen or the analysis screen. In-battle dialogue takes up time.

Trivia

 * Okumura's death (bleeding black liquid from his orifices, like all mental shutdown victims) is reminiscent of a scene in Persona 3 where a victim dies similarly.
 * Okumura's poor treatment of his employees and ambition to enter the political circle is likely based on (渡邉 美樹), who was originally the CEO of the restaurant chain where a female worker committed suicide allegedly for working severely overtime. Despite the scandal, Watanabe was elected to the House of Councillors representing the (conservative)  in 2013.
 * Shadow Okumura's costume is very reminiscent of super villains in 1980's science fiction. The panel before his torso is particularly similar to 's from the  franchise.
 * Shadow Okumura's plot to escape to utopia in a flying saucer and destroy everything left behind may be a call back to the Millennium Kingdom project from Shin Megami Tensei II and Xibalba/Ameno Torifune from Persona 2.
 * Okumura is the only target that the protagonist (or any Phantom Thieves members he has no affiliation with) never personally meet in Persona 5. In Royal however, the protagonist will personally encounter him from January 3rd to January 8th.
 * According to Haru in Persona 5: Dancing in Starlight, Okumura owned a yacht.
 * Shadow Okumura is the only target in Persona 5 that does not transform when fought. However, Takuto Maruki from Royal and Akira Konoe from Persona 5 Strikers do not change in appearance save for their outfits.
 * Unused files in Persona 5 indicate the existence of a book called "The Okumura Way." Its description is as follows: "Memoir of Kunikazu Okumura, whose life philosophy pioneered a new age."
 * If Yoshizawa and Akechi are manually put into the party via save editing, Okumura cannot order his robots to target them.
 * Texts written on the crane devices which summon the robots in Okumura's boss battle are:
 * Overtime (Standard Workers)
 * Nominal Manager (Chief Clerk/Section Chief)
 * Thanks Worldwide (Executive Director)
 * Consulting  (No one left in Persona 5, Cognitive Haru remaining in Royal)
