In the 1970s, he formed a comedy duo with his friend Nirō Kaneko (also called Kiyoshi Kaneko). They took on the stage names Beat Takeshi and Beat Kiyoshi; together referring to themselves as Two Beat. This sort of duo comedy, known as manzai in Japan, usually features a great deal of high-speed back-and-forth banter between the two performers. Kiyoshi played the straight man (tsukkomi) against Takeshi’s funny man (boke).

In 1976, they performed on television for the first time and became a success, propelling their act onto the national stage. The reason for their popularity had much to do with Kitano’s material, which was much more risqué than traditional manzai. The targets of his jokes were often the socially vulnerable, including the elderly, the handicapped, the poor, children, women, the ugly and the stupid. Complaints to the broadcaster led to censorship of some of Kitano’s jokes and the editing of offensive dialogue. Kitano confirmed in a video interview that he was forbidden to access the NHK studios for five years for having exposed his body during a show when it was totally forbidden.
