Watanabe was born on October 21, 1959, in the mountain village of Koide in Niigata Prefecture, Japan. His mother was a school teacher and his father taught calligraphy.[4] Due to a number of relocations for his parents' work, he spent his childhood in the villages of Irihirose and Sumon, both now part of the city of Uonuma, and in Takada, now part of the city of Jōetsu. He attended Niigata Prefectural Koide High School, where he was a member of the concert band club, playing trumpet, which he had played since childhood.
After graduation from high school, in 1978 he aimed to enter Musashino Academia Musicae, a conservatory in Tokyo. However, he had never received a formal musical education, and his father became seriously ill when he was in junior high school and was unable to work, which meant that his family could no longer afford to pay for his music lessons.[5] Because of these problems, Watanabe was forced to give up his intention of entering the conservatory. He said of the decision: "I had to give up my musical aspirations. I realised I had no talent as a musician. But I still wanted to find a way to be creative, so I decided to try acting".[5]

Watanabe formally adopted Minami's son from her previous marriage to director Jinsei Tsuji, and for a time the three of them lived in Los Angeles. In order to increase the amount of time the family could spend together, considering Ken's work requiring him to travel so much, they later returned to Japan.
