Isao Ohta

Isao Ohta is a patrol officer from Kamaishi, Iwate Prefecture.

His rank is initially patrolman, and he is later promoted to sergeant.

Captain Kiichi Goto famously calls him a "problem policeman."

That label fits: Ohta is earnest, brave, and deeply committed to law and order, but he is also impulsive, stubborn, and dangerously eager to charge straight into trouble.

He pilots the forward seat of Unit 2.

In both temperament and fighting style, he is the opposite of Noa Izumi: where she tends toward finesse, he favors brute force and immediate action.

He is voiced by Michihiro Ikemizu.

His live-action actor is Morihiro Yamaguchi.

Ohta is the classic fiery, straight-laced officer.

At his best, he is sincere, courageous, and unwaveringly protective of the public and his comrades.

At his worst, he is a headstrong fool who rushes in before thinking.

He is strict about discipline, obsessed with hierarchy, and not especially flexible.

He tends to obey people who outrank him or clearly surpass him in skill.

At the same time, he often clashes with fellow team members, especially Asuma Shinohara.

Even so, his concern for the team is genuine.

When danger appears, he is always ready to rush to their aid.

In the early manga, he looked down on the other members of the unit because many of them came through the so-called police preparatory school system rather than traditional police training.

This attitude reflects both his pride and his background as one of the few members with a conventional police education.

He can be abrasive in everyday life.

He is short-tempered, quick to anger over small things, and sometimes rude in a very old-fashioned way.

He also shows traces of seniority worship and conservative gender attitudes.

Still, his behavior is more complicated than simple chauvinism.

He never really treats Noa Izumi as lesser because she is a woman.

In fact, he is relatively gentle with her, and sometimes gives her awkward, shy advice.

By contrast, he initially reacts badly to highly capable women such as Kanuka Clancy and Takeo Kumagami.

He complains about them, but because they outrank him and prove their ability, he still follows orders.

That is a key part of Ohta's character.

He may resent authority, but he sincerely believes rank matters and that organizations collapse without respect for hierarchy.

He can also be surprisingly teachable.

When someone demonstrates genuine skill in judo, piloting, or command, he may grumble, but he will eventually acknowledge it and even ask to learn.

Among the members of the second unit, Ohta is one of the few who received standard police training.

Along with Captain Kiichi Goto and Takeo Kumagami, he represents a more traditional Japanese police career path.

Before joining the Labor unit, he served as a uniformed police officer and riot police member.

In the manga, before his transfer background is fully explained, he appears as a regular officer and even tries to force his way onto a unit from Division 1 to fight the criminal Labor known as Hercules 21 with his bare hands, only to be stopped by fellow officers.

This background explains a lot about him.

He has stronger instincts as a front-line officer than many of his younger teammates.

He is often the most conventionally police-like member of the squad.

He is job-focused, serious about duty, and generally diligent in his work despite all the chaos he causes.

Ironically, that makes his worst habits even more troublesome.

He is not reckless because he is untrained; he is reckless despite being properly trained.

Ohta's piloting style is forceful and direct.

He prefers charging in over delicate or highly precise maneuvering.

He makes decisions quickly and rarely hesitates.

However, he lacks tactical flexibility and can become locked into a single approach.

This is why he often destroys his own machine.

His superiors scold him, and the maintenance crew constantly complains about the damage he causes.

He also has a habit of ignoring backup instructions and acting on his own.

Kanuka Clancy and Takeo Kumagami, both sergeants and both superior to him in skill and authority, are often the only people who can rein him in.

He is skilled in judo, which suits his aggressive style.

In physical confrontations, that straightforward toughness works in his favor.

One of Ohta's most famous traits is his relationship with the revolver cannon, the handgun used by Labors.

He is infamous for wanting to fire it at every possible opportunity.

In casual conversation, he comes off like a trigger-happy maniac.

He wants to shoot during combat, crowd control, rescue operations, and almost any tense situation.

This reputation is not entirely undeserved.

In the manga, during the second unit's first deployment, he warns a suspect to stop or he will fire, while privately hoping the target does not stop.

When the suspect actually keeps coming, Ohta becomes delighted and starts firing repeatedly.

After emptying his ammunition, he even demands more rounds.

The animated works continue this image.

Whenever a gunfight seems possible, he is visibly excited and starts preparing ammunition with alarming enthusiasm.

Yet his marksmanship is more nuanced than his reputation suggests.

In real incidents, he often misses, but this is largely because he aims for extremely difficult nonlethal targets such as joints and the tips of limbs.

He is trying to disable criminal Labors without hitting the cockpit.

Captain Kiichi Goto is the one person in the unit who fully understands this, joking that Ohta has never actually hit a cockpit by accident.

In training on stationary targets, his accuracy is shown to be excellent.

The manga explicitly depicts him placing nearly all his shots near the center of the target after post-repair practice following the Griffon battle.

He also lands hits in real operations when the target is less erratic.

He damages the Griffon's main camera while coordinating with Hiromi Yamazaki and even scores a hit on the head of a Brocken, though it is ineffective.

During the Waste 13 incident, in both the film and manga versions, he carefully chooses the moment to fire a single special round and succeeds.

That scene underlines that, beneath all the bluster, he does know when a shot matters.

His proficiency is tied to the fact that the revolver cannon is not fully integrated with fire-control automation.

He is effectively using it in a semi-manual manner and teaching the Ingram's operating system through experience.

By the time of the second film, this practical skill helps earn him a role as a Labor pilot instructor.

He strongly believes pilots must learn manual operation in case the fire-control system fails.

There is also a rare scene in the television series that shows his restraint.

While Mikiyasu Shinshi temporarily serves as Unit 2's backup officer and gives permission to use the gun, Ohta notices that civilians have not been fully evacuated and that a school lies behind the target through the sightline.

At that moment he refuses to fire, saying that a stray shot could hit the school.

For a character known for loving gunfire, it is one of his clearest demonstrations of professional judgment.

Noa Izumi

Ohta often treats Noa Izumi more kindly than he treats others.

He may be awkward and embarrassed about it, but he sometimes offers brief advice and concern.

He does not seem to belittle her in the same way he belittles some of the police preparatory school graduates.

In that sense, he can be less overtly biased toward her than Asuma Shinohara, who is more visibly conscious of her as a woman.

Asuma Shinohara

Ohta and Asuma Shinohara clash constantly.

Their personalities are almost designed to irritate each other.

Ohta prefers direct action and dislikes overthinking.

Asuma tends to analyze motives, context, and consequences, which Ohta often sees as needless hesitation.

At one point, when Asuma is put together with Ohta by Captain Kiichi Goto, their partnership becomes so troublesome that Takeo Kumagami openly complains about it.

Their friction is one of the defining internal tensions of the team.

Kanuka Clancy and Takeo Kumagami

Ohta initially dislikes both women.

He finds them too strong-willed, too capable, and not in line with his idealized image of femininity.

Still, he does not openly defy them once hierarchy is established.

Because both outrank him and repeatedly prove their competence, he obeys them even while seething.

When Asuma points out that Ohta submits because of rank, Ohta is nearly in tears with frustration.

Even then, he insists that rank differences are absolute within the police and that the chain of command must be upheld.

Over time, his resentment softens into respect.

He eventually seeks guidance from those he once resisted.

Mikiyasu Shinshi

Ohta's relationship with Mikiyasu Shinshi is less explosive than his relationship with Asuma, but still revealing.

In one exchange in the manga, Ohta defends his understanding of responding to rescue support requests, showing that his instincts as a police officer are often sound.

By the period of the second film, Shinshi has risen to a senior administrative post.

He later complains when Ohta, now an instructor, destroys training equipment after already demonstrating perfect manual shooting.

Ohta is not just a loud brute.

He has several unexpected traits that make him more human and more entertaining.

He is a fan of young female idols.

In the television series, he becomes utterly smitten with Kana Matsumoto, who is promoted as the number one celebrity people would want as a little sister.

He is even revealed to be fan club member number 0001.

That detail adds an unexpectedly nerdy side to his otherwise hardboiled persona.

In the manga, there is no idol-centered episode, but when he repeatedly leaves work on time, the rest of the squad starts joking about what he is hiding.

They speculate that he might have a girlfriend, might be secretly committing gun crimes, might be rushing home to record television anime reruns, or might be creating comic books for a fan convention.

The truth is much simpler.

He just wants to get to the cafeteria before a limited seasonal large-portion meal sells out.

He can also be unexpectedly considerate in romance-related situations.

Despite his rough edges, he tries to escort an arranged-marriage partner with clumsy sincerity.

This side of him appears in the television series, where he is briefly presented as more of an adult man than his usual comic image suggests.

He is not as simple or insensitive as everyone around him likes to claim.

Ohta has unusually strong tolerance for gruesome crime scenes.

This appears to come from his early police experience.

For some reason, he encountered a series of terrible corpses in his first year as an officer.

As a result, he developed a resistance that the others do not share.

In the manga, when the rest of the team faints or runs to the restroom after seeing a horrific body, Ohta remains perfectly calm.

He later eats a meat dish without any trouble.

He boasts that he vomited enough in the past to learn how to separate his stomach from his brain.

Asuma immediately replies that this is not something to be proud of, which of course turns into another argument.

By the autumn of 2001 in the continuity of the original video animation and films, Ohta has been promoted to sergeant.

He is transferred to the Special Vehicles Personnel Training School as an instructor.

His temperament does not improve much.

In the second film, he harshly berates students who are poor shots with a Labor.

To demonstrate proper technique, he fires manually without fire-control support and hits a moving target cleanly.

Then, because he believes one must never forget to finish the job, he smashes the target mechanism itself with an electro-stun baton.

Mikiyasu Shinshi, now serving in a senior headquarters position, complains about the destruction of equipment.

Ohta remains unmistakably himself.

Some design notes suggest he was intended to appear slightly calmer at this stage.

In the completed work, however, he still behaves much as he always did.

Live-Action Continuity

In the live-action continuity tied to the earlier original animation and film timeline, Ohta's later life is bleak.

After the events following the second film, he leaves the police and starts a security company with Captain Kiichi Goto and Mikiyasu Shinshi.

The business collapses in less than a year due to poor management.

After that, for reasons not fully explained, Ohta becomes involved in a violent incident and is imprisoned.

Among the known former members of Division 2, he is in the worst condition.

For fans, it is a notably tragic outcome.

Reboot Continuity

In the short film Patlabor Reboot, Ohta is not directly named.

However, a female captain quotes the phrase, "When facing the field, respond with flexibility," which is one of his well-known lines.

This has led to speculation that he may have succeeded Captain Kiichi Goto as commander of Division 2.

Among the original members, he and Takeo Kumagami are among the most plausible candidates to have risen high enough in rank.

Ohta was modeled after a diving instructor of the same name.

According to creator comments, the later design drifted somewhat, and the early design draft looked closest to the real-life model.

An early rough sketch published in a graphic special presents a very different impression.

There, he appears as a clean-cut young judo practitioner with a square haircut and a constant smile.

That version is far softer than the Ohta who reached the finished story.

The final character became one of the franchise's most memorable human powder kegs.

Michihiro Ikemizu, who voices Ohta, also performs the opening narration in several animated entries, including the early original animation, the television series, and the later original animation.

Those narrations are calm and composed, making the contrast with Ohta's explosive personality especially amusing.

This contrast is even used for comedic effect in the short parody work Mini Pato.

Many viewers were surprised when they first realized the same actor performed both roles.
