Ken Shimura(志村 けん,Shimura Ken?) (born Yasunori Shimura(志村 康徳,Shimura Yasunori?), February 20, 1950 in Higashimurayama, Tokyo), is a Japanesecomedian and actor. He co-starred with Masashi Tashiro, Nobuyoshi Kuwano in the Japanese variety show "Ken Shimura no Bakatono-sama". The "bakatono-sama" shtick by Shimura is unusual among Japanese comedians, in that he could satirize the deeds of current guardians of the contemporary society (a company president, a politician, a family head, a school principal, the head of a Japanese yakuza gang) under the garb of a 'foolish' king who lived in the country longtime ago. Another of popular shtick of Shimura in the same show is "Henna Oji-san" [an obnoxious uncle character] who entertains himself in the company of nubile girls. After being caught for his pranks, the character regularly ends the shtick with a song 'Sou desu. Watashi wa Henna Oji-san desu'.
From September to October 1996, a rumor circulated that he had died.
In 2001, he did a duet with Naoko Ken as "Ken♀♂Ken" in "Ginza atari de Gin Gin Gin" (銀座あたりでギンギンギン?).
In April 2002, he recorded a one-off single with Hello! Project's unit "Mini Moni", with the collaboration credited to "Bakatono to Mini Moni Hime" (バカ殿様とミニモニ。姫?). They recorded two songs named after a catch phrase of his, "Ai-in".
His stage name "Ken" comes from his father's name "Kenji" (憲司?). His father worked as a vice-principal in an elementary school, and Shimura was brought up in a strict family. However, his father suffered from dementia since he was involved in a car accident in front of their home when Ken was in junior high.
