Early life

Watanabe was born in Koide, Niigata. His mother was a school teacher and his father taught calligraphy. 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 because his father had collapsed when he was in junior high school and was unable to work, there was difficulty in finding the money for tuition. Because of these problems, Watanabe gave up trying to enter the conservatory.

Career

Japanese roles

After graduating from high school in 1978, Watanabe moved to Tokyo to begin his acting career, getting his big break with the Tokyo-based theater troupe En. While with the troupe, he was cast as the hero in the play Shimodani Mannencho Monogatari, under Yukio Ninagawa's direction. The role attracted critical and popular notice.

In 1982, he made his first TV appearance in Michinaru Hanran (Unknown Rebellion), and his first appearance on TV as a samurai in Mibu no koiuta. He made his feature-film debut in 1984 with MacArthur's Children.

Watanabe is mostly known in Japan for playing samurai, as in the 1987 Dokuganryu Masamune (One eyed dragon, Masamune) the 50-episode NHK drama. He played the lead character, Matsudaira Kurō, in the television jidaigeki Gokenin Zankurō, which ran for several seasons. He has gone on to earn acclaim in such historical dramas as Oda Nobunaga, Chushingura, and the movie Bakumatsu Junjo Den.

In 1989, while filming Haruki Kadokawa's Heaven and Earth, Watanabe was diagnosed with acute myelogenous leukemia. He returned to acting while simultaneously undergoing chemotherapy treatments, but in 1991 suffered a relapse.

As his health improved his career picked back up. He co-starred with Koji Yakusho in the 1998 Kizuna, for which he was nominated for the Japanese Academy Award for Best Supporting Actor.

In 2002, he quit the En (Engeki-Shudan En) theatre group where he had his start and joined the K-Dash agency. The film Sennen no Koi (Thousand-year Love, based on The Tale of Genji) earned him another Japanese Academy Award nomination.

In 2006, he won Best Lead Actor at the Japanese Academy Awards for his role in Memories of Tomorrow (Ashita no Kioku), in which he played a patient with Alzheimer's Disease.

International films

Watanabe was introduced to most Western audiences in the 2003 American film The Last Samurai, set in 19th Century Japan. His performance as Lord Katsumoto earned him an Academy Award nomination for Best Supporting Actor.

Watanabe appeared in the 2005 film Memoirs of a Geisha, playing Chairman Iwamura. That same year, he also played Ra's al Ghul's decoy in Christopher Nolan's Batman film reboot, Batman Begins. In 2006, he starred in Clint Eastwood's Letters from Iwo Jima, playing Tadamichi Kuribayashi. He has voiced Ra's al Ghul's decoy in the Batman Begins video game. He has filmed advertisements for American Express, Yakult, Canon and NTT DoCoMo. In 2004, he was featured in People Magazine 's 50 Most Beautiful People edition. In 2009, he appeared in The Vampire's Assistant. In 2010, he co-starred in Inception, where he stars as Saito, a mark-turned-benefactor businessman of the film's heist team. In 2014, he starred in the Hollywood blockbusters Godzilla and Transformers: Age of Extinction.

Personal life

In 1983, Watanabe married his first wife, Yumiko. In March 2005, following two years of arbitration, he and Yumiko were divorced. He got to know Kaho Minami when they were acting together in a suspense drama for TV Tokyo. Around the time of his divorce the two began seriously dating, and were married on December 3 of the same year. The couple's relationship was initially kept out of the mass media. It was not until an "unidentified guest" accompanying Watanabe at a New York premiere of his film Sayuri who is seen in an Associated Press photo was found to be Minami that their marriage was publicly announced.

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. Initially Minami and Ken did not hold any wedding ceremony, but in 2010, marking their fifth anniversary, they announced that they had held a ceremony in Los Angeles.

Watanabe has two biological children and an adopted son. His oldest son, Dai Watanabe (born 1984) is an actor, and his daughter Anne Watanabe (born 1986) is also an actress and fashion model. In August 2008, Dai had his first child, making Ken a grandfather at the age of 48. As of 2014, Watanabe has two grandchildren.

In 1989 Watanabe was diagnosed with acute myeloid leukemia. The cancer returned in 1994, but he later recovered.

In 2006 Watanabe revealed in his autobiography Dare? - Who Am I? that he has hepatitis C. At a press conference held May 23, 2006 in Tokyo's Ginza district, he said he was in good condition but was still undergoing treatment.

On March 13, 2011, he launched a YouTube page to raise awareness about the 2011 Tōhoku earthquake and tsunami and invited celebrities to add their videos. In his video in English, he made a call to action to support the victims and to raise funds in the relief effort. In conjunction, he has created his own website for the cause.

On February 9, 2016, it was revealed Watanabe had been diagnosed with stomach cancer and would postpone scheduled performances to undergo necessary treatment.
