Kankichi Ryotsu (両津勘吉, Ryōtsu Kankichi) (Ryoutsu), often affectionately called "Ryo-san" (両さん, Ryō-san), is the main male protagonist/anti-hero of the long-running Japanese manga and anime series KochiKame by Osamu Akimoto. He is appointed as the Chief Patrol Officer of the Kameari Kouen-Mae Police Box.


Ryotsu's appearance in the manga (full colour).

Ryoutsu is a middle-aged man of a rather short but robust stature, who sports a crew-cut hairstyle and noticeably thick bouts of body hair, plus visible stubble. His similarly extra thick and curvy 'm'-shaped unibrow is his most famed asset, and serves as the signature image associated with Kochikame in general due to its uniqueness and familiarity with local Japanese fans.

While on duty, he is always depicted wearing his blue police officer uniform, i.e. blue pants and coat which cover his white buttoned shirt underneath, plus a black tie. Unlike, most other police officers from the series who wear the same uniform as he, Ryotsu keeps his sleeves rolled up to just above the forearm, similar in fashion to Honda. He also has the tendency to wear wooden sandals (called 'geta') whilst at work, but is able to run at rather tenaciously fast speeds with them on (which may, or may not be, the reason as to why he does not wear black shoes).

In his spare time, Ryotsu commonly wears shirts and long pants when out with the others. Holiday episodes set in summer or beach holiday spots usually have him wearing an island shirt with shorts, sunglasses, and sandals. When in the midst of intense physical work, he appears to favor wearing white sleeveless tops and jeans or trousers, and may sometimes choose to go shirtless.


Ryotsu was born and raised in Asakusa from Taito Ward in Tokyo Prefecture. In his youth...

Typically played with two of his close friends.

It can be assumed that the three friends parted ways after they graduated from high-school. They are not seen again with Rytosu during his interim period as an unemployed young man.

He was also extremely mischievous as a child growing up into a young adult, with his antics ranging from climbing a factory smokestack to hijacking a bascule bridge, even though he meant well in both instances. Due to such antics and his natural behavior in general, people tended to assume the worst of him, having had to deal with him for many years. This mentality is most often seen with Naoko Seisho and Komachi Ono whenever they see Ryotsu, referring to him as an uncivilized caveman and claiming that he was always up to no good. As a result, Ryotsu tends to get rather annoyed and angry whenever such claims are made about him. (Though this proves to be justified, more often than not.)


Ryotsu tends to adopt a rather lazy state of disinterest while on duty at the Police Box; instead of putting effort into his patrol or office duties, he is often seen resorting to creating plastic models (puramo), playing with toys and video games or sleeping on the job instead. It is usually while he is in the middle of any of these activities, however, that Bucho catches him off-guard and consecutively scolds him for disobeying orders.

As a result of being brought up in a poor family background, Ryotsu has developed a sort of aggressive attitude towards means by which to properly invest, save and spend money in current affairs, aside of his illegal moneymaking schemes. He is fond and takes pride in the Japanese culture and lifestyle; he is skilled at a number of traditional games and activities which include Shogi, Beegoma and Kendo.

Ryotsu resides in the Niconico (Smiley) Hostel apartment block, which is home to primarily single male tenants and police officers from the Katsushika Police HQ. He commutes to the Police Box from this location via his white bicycle named Chidori, more often than not arriving late in the morning, to Bucho's constant annoyance.

Ryotsu's Entertainment Stall. A true catalyst of his greed and scheming for money. This was eventually expanded into a multi-story stall that was then converted into a train of multiple stalls. (episode 44)

He shows larger preferences for indulging in leisure activities inclusive of Pachinko, gambling, plastic model construction, video gaming and visiting cabaret clubs, especially whilst on patrol duty. But his largest desire above all is for money, and will go to great extents just to earn big cash by investing in on potentially profiting fads and scams just for his benefit. Almost all of these, in the end, are never able to reach a pleasant conclusion. There will always be some form of major damage or tarnished reputation of the police force.

There are times when Roytsu shows great in-depth knowledge and understanding of current fads or situations in the business, sports, culture, or leisure industry, and can sometimes go into deep discussions with colleagues Nakagawa and Reiko regarding these subjects. The topics always cover modern trends and fads in line with current real-life trends and fads, inclusive of smartphone apps and Playstation games in recent manga volumes. Ryotsu is especially knowledgeable in topics relative to the Japanese lifestyle he was raised in, which contrast the more globally-experienced perspectives of Nakagawa and Reiko.

Ryotsu is unable to speak any other language other than Japanese, and seems to show little concern over this. He understands only little bits of broken English, particularly where speaking foreign characters are concerned. He does, however, make occasional mentions of typical English conversational phrases such as 'thank you' and 'no problem' in both the manga and anime to other characters. Reliance is put onto both Nakagawa and Reiko for translating between languages.



Ginji Ryotsu

Ryotsu has a very strained relationship with his father. Both are extremely prone to fighting, despite their very similar personality traits and mannerisms. He also resembles his father the most, in comparison to his mother, sharing his body type, hairstyle and facial features (excluding the monobrow).

Yone Ryotsu

Ryotsu appears to get on better terms with his mother than his father. She can become strict in cases where her son doesn't listen, but only wishes for him to do good and act with discipline or sensibility at the very least. She is also having to always control the fights that occur between her husband and son, and as a result is viewed as the voice of reason in the family, given her more even-tempered nature and ability to make more just decisions.

Kinjiro Ryotsu

Little is known about the relationship between Ryotsu and his younger brother Kinjiro. But it is apparent that Kinjiro shows more respectful behavior than his older brother, due to his above-average intelligence and success as a businessman, successes which are considered rare for a member of the Ryotsu family. Unlike his older brother, he is married and receives a more steady income.

Police Box Colleagues

Keiichi Nakagawa

Ryotsu generally maintains a good friendship with Nakagawa both during and outside of work. He can often be seen in discussion over particular topics, and tends to offer his own thoughts in-line with his own cultural Japanese background that contrasts Nakagawa's more global perspectives.

His plans for inappropriate or potentially dangerous schemes are always met with opposition from Nakagawa. At times, he vents his anger onto him for being in some way more fairly treated than he is, given his more rich and prosperous background which contrasts Ryotsu's own, as he was brought up poor and with less world knowledge. On the other hand, Ryotsu is glad to have Nakagawa help him fulfill materialistic aspects of a scheme by receiving assistance from the Nakagawa Corporation.

There are instances where Ryotsu is successful in showing Nakagawa's vulnerable 'insane' side, by persuading him to drink or pulling jokes to make him laugh uncontrollably.

Reiko Katherine Akimoto

Ryotsu appears to work well with Reiko; she most often can be seen offering him tea while he is in the midst of work or play, and talking to him over the topic of interest or matter at stake.

Unlike Nakagawa, Reiko is able to provide Ryotsu with information from a female perspective, particularly where relationships with women or feminine activities are sometimes concerned. Their gender differences have also been the butt of several jokes, usually with mild sexual implications; Ryotsu's involuntary moments of nudity are met with extreme shock and revulsion from Reiko (most apparent in the anime), whilst Reiko's occasional partial nudity or vulnerability fully nude causes a degree of wonder and wishful thinking of a 'surprise' encounter by Ryotsu (most apparent in the manga).

Daijiro Ohara (Bucho)

Ryotsu and Bucho are notorious for their consistently strained relationship with one another in the series throughout. Bucho is most famous for his yells of Baka Mon! (バカモン), roughly translated as "You Idiot!", when he discovers Ryotsu disobeying orders and deviating from his police work. Ryotsu is always willing to take risks in doing other activities despite the chances of him being discovered again, much to the frustration and constant anger of Bucho.

It is suggested that the two share a sort of father-son type of relationship in spite of their turbulent times together. Bucho sincerely only wants for Ryotsu to be better disciplined and hard-working in his job, partly to prevent him from tarnishing his reputation as the Head of the Police Box. He also cares for Ryotsu, and truly believes that he is capable of making the Police Box a success, although he tends to keep these feelings suppressed to maintain his image.

Bucho takes immense pride in Ryotsu during times where the latter is successful in battling a crime or doing good for society, and can sometimes be moved to tears out of emotional moments.

Ryotsu and Ohara's first encounter. A precursor of their future relationship with each other.

Throughout the anime, it is shown that the relationship between Ryotsu and Ohara stems back many, many years, to the point where Ohara was a newly minted police officer and Ryotsu was a civilian troublemaker. They first met when Ryotsu and his friends (at the time in high school) hijacked the control room of a bascule bridge, leading to Ohara hanging perilously from the edge of the bridge, and resulting in the then-police officer to fall into the river. Ohara and Ryotsu were formally introduced to each other when the former arrested the latter for public drunkenness. This event may have inspired Ryotsu to join the police force, and subsequently partnered with Ohara as a patrolman. It should be noted that Ryotsu's sandals were bought for him by Ohara in his earlier years on the force after the former complained about how uncomfortable the policeman shoes were, and has been worn by him ever since then.

Katsushika Police HQ colleagues

Hayato Honda

Honda and Ryotsu caught while conducting one of Ryotsu's schemes.

Ryotsu is often seen alongside Honda during both in and out of work shifts, outside of the Police Box. The two appear to have a good friendship, as Honda is understanding of Ryotsu and seems to support him a lot, although he is also less likely to strongly oppose Ryotsu's more dangerous ideas given his sensitive nature. Honda is also of extra help to Ryotsu, as he is able to transport him anywhere on his motorbike. 

In his normal persona, Honda addresses Ryotsu as senpai (先輩), whereas his 'transformed' motorcycle persona addresses him as Ryotsu no Danna (両津のダンナ).

Ryotsu is sometimes fed up with Honda's indecisive and cowardly nature, and may resort to either venting his anger onto him or simply ignoring him to carry out whatever he wishes, causing much worry in the former. 

Despite Honda's personality shifts, he still treats Ryotsu with an extremely deferential manner. Ryotsu is prone to manipulating Honda to his needs, convincing his friend that he broke a "¥30,000" model, when in reality it was but a meager ¥100 set picked up from a convenience store.

Ai Asato (Maria)

Ryotsu initially became infatuated with the deceivingly attractive attributes of Maria, prior to finding out that she was male. Since the discovery, Ryotsu began to act more emotionally distant from her, but doesn't show any dislike. He does appear to agitate in moments where he is hugged by Maria without warning.

Matoi Giboshi

Ryotsu had initially shown much interest in Matoi following her debut in the manga series, given her tomboyish personality and interests which seemed to match Ryotsu's own. It went far enough to prompt Ryotsu to marry her, until it was revealed last-minute that she was actually his cousin. Since then, the two behave with a sibling-like relationship when together.

Despite that fact that Ryotsu was brought up in a wholly Japanese environment, just like Matoi, she actually appears to know more about culture and traditions which Ryotsu has either been unaware or ignorant of, to the embarrassment of other characters.

Aside their difficult moments, the two of them both love to participate in and attend cultural festivals, especially those which take place in Asakusa, the native hometown of Matoi.

Haya Isowashi

Since her debut in the manga, Ryotsu has shown ample interest in Haya and is more than willing to attempt to win her over, given her sheer intelligence in Japanese culture, archery and good looks. Her strictly conservative and intimidating father, though, has been his only obstacle which stops him from properly being able to access her numerous times. Ryotsu also ends up having to face competition from many other male colleagues in the HQ -including Bucho- due to her popularity, and always ends up having to find a way to be able to get together with her without their intrusion. He is always more than appreciative of being in Haya's presence when they are together.

Komachi Ono and Naoko Seisho

Naoka/Komachi and Ryotsu typically find themselves at odds. In this case, it was competing their respective newspapers against each other.

Both Komachi and Naoko share strained relationships with Ryotsu in the anime series; the trio are almost always seen bickering and mocking one another over trivial matters. The duo often resort to insults that threaten his ego due to his obscene behavior (in true perspectives), such as calling him a 'caveman' and the 'man least likely to ever marry'. Ryotsu would often go to great extents to prove them wrong by accepting challenges they make.

There are instances, on the other hand, where the trio seem to get along amicably, although these cases are rare.

Saigou Volvo

Tatsunosuke Sakonji

Gomez Tonda (Shocho)

Ryotsu is apparently very aware of the way Shocho seems to more often than not be strayed away from his own work duties, through activities such as reading men's magazines and visiting cabaret clubs. He has been successful in being able to trick Shocho into giving in to his scams, given his somewhat gullible persona, which happens sometimes whenever Ryotsu feels some form of disapproval over certain actions that he takes e.g. providing low pay or denying requests. It is always in the end, however, that Shocho finally realizes -alongside Bucho- the true harmful consequences of Ryotsu's plans. 

Other characters

Lemon Giboshi

It is made clear in the manga that Lemon possesses much more knowledge of Japanese culture than Ryotsu does, despite the fact that she is only four years old. Ryotsu seems to feel belitted and short-tempered in times where she is able to prove him wrong in areas of Japanese culture, which range from writing kanji characters correctly (one of his major weaknesses) to properly tasting sushi dishes, and determining the correct species of seafood or fish used in the given dish.

Korosuke Ezaki (Professor Ezaki)

Ryotsu is always finding himself becoming a gorilla to technically all of Professor Ezaki's prototype inventions. While a significant number of his 'inventions' tend to be somewhat beneficial -for instance, reducing an adult to a child to re-live childhood for a limited time frame- there are always faults or limits which Ryotsu ends up suffering from, and experiences their consequences, often to the most destructive degree imaginable.

Reiji Shiratori

It could be said that Ryotsu is both grateful for and envious over the extremely wealthy Shiratori who makes occasional appearances in the series. During Shiratori's famous money-throwing scenes, Ryotsu can always be seen lunging forward to grab as many dollar notes as possible. At the same time, Ryotsu is also at odds with the boastful and overconfident nature of Shiratori, often responding by acting coldly or aggressively to him. Ryotsu would make whatever attempt possible to threaten his reputation or wealthy status by placing him in potentially dangerous or demeaning situations, which have been successful in the past, but also end up affecting him too to an equal degree.

The Heavenly Administrator

Ryotsu shares a less-than-favorable relationship with the Heavenly Administrator: God's reagent of karmic justice, chiefly due to the fact that he is always engaging himself in situations which are perceived as more sinful than helpful in the eyes of the Administrator himself. Ryotsu's harmful pranks, tricks and money-related scams are apparently all recorded by the Admin (to his annoyance), and given 'punishment points'. However, despite the Admin's attempts to punish Ryotsu via karma, the latter typically finds a way to turn the situation to his favor. (I.e: Eating food that wasn't his. Admin turns food bad. Ryotsu gets an upset stomach. Ryotsu uses upset stomach as an excuse to bail on work.) This escalates to a point where the Administrator descends upon the Police Box and transforms Ryotsu into a minuscule version of himself in order to teach him a lesson. As expected, this backfires upon the Heavenly Administrator.



  • His birthday is marked on 3rd March, which is a day known as Hinamatsuri (雛祭り) in Japan, alternatively called the 'Girls' Festival'. Ryotsu hates his birthday due to its implications on his persona, being a grown man, and is always a day fought with peril; an experience in his youth which apparently mocked the celebration resulted in a curse being brought upon him on a yearly basis which results in catastrophic events and mishaps that only frustrate and injure him further.
  • It is estimated that Ryotsu has appeared in every single chapter from the manga series since its initial debut in 1976, which already spans a total of more than 1900 different storylines combined. The same is also true for the anime series, which spanned a total of 344 episodes between 1996 to 2004.
  • Outside of the manga and anime series, Ryotsu has made numerous appearances and crossovers in other popular manga series and Weekly Shonen Jump specials.
