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-management senior cop. Sporting a small trimmed mustache, akin to Hitler, Bucho is often out of touch or exasperated with his younger staff, but he always ready to punish Ryo-san for his laziness (Despite this, he shows kindness to Ryotsu occasionally, treating him as the son he never had).
