The Chief Patrol Officer of Katsushika, in charge of the police box in front of Kameari Park. He usually called "Buchō" or "Division Head" (部長) and is Ryotsu's boss. He is a typical grizzled middle manager senior cop. Sporting a small trimmed mustache, Bucho is often out of touch or exasperated with his younger staff, but always ready to give out punishment to Ryo-san for his laziness.(But he treats Ryotsu like his son because he does not have son, so he is kind to Ryotsu by heart.) He is a father-like figure for Ryoutsu, Reiko, and Nakagawa. His many hobbies include Judo, Kendo, Sado, Bonsai, and calligraphy. He comes to hashutsujho by bus and train. He gives many punishments to Ryoutsu. He also wears army costumes with holding guns or rides on the tank and goes to Hashutsujyo to give punishment to Ryotsu.(In this scene, Ryotsu makes troubles, that make Ohara ashamed, so he wears costumes and rides on tank to give punishment to Ryotsu, however Ryotsu is not there, then Nakagawa or Terai tells where Ryotsu went.)

The typical Kochikame plot involves Ryo-san coming up with a money-making scheme by inventing a new gadget or capitalizing on a fad, achieving great success, calling on Nakagawa's help as things turn sour, and finally losing it all as the fad runs out of steam or out of control. While the plots are gag-driven, much of the humor comes from the juxtaposition of mundane characters with the bizarrely incongruous (Nakagawa's wealth, Maria's appeal, everyone's lack of actual police work), most of which is never explained or rationalized in the slightest.

To celebrate the 40th anniversary of the manga a new TV anime project has been announced.

Haruki Sayama is a singer, actor, voice actor from Yokohama, Kanagawa Prefecture, Japan.  

The wicked multi-billionaire, Shinatora, builds wretched, ugly buildings. The explosives genius calling himself Benten has targeted Shinatora's empire and begins to destroy the monstrosities that are wiping out whole sections of downtown Tokyo. In cooperation with the local police force, the FBI has sent Lisa Hoshino, a bomb disposal expert, and her robot assistant, Dandy, on a lecture tour of Japan. Ryotsu is reluctantly paired with Lisa to protect the people of the Kameari district. Why does Benten only target Shinatora's buildings? What is his next target? 
Another email warning arrives at the Katsushika Police Station. Benten's next target is the newly built, gigantic amusement park, Shinatora World. Lisa and Ryotsu hurry to the scene. What they find is a huge Soviet-era rocket armed with a massive bomb powerful enough to obliterate the entire area of Katsushika. 
What can Ryotsu do?
