Keiji Nakazawa (中沢 啓治 Nakazawa Keiji, March 14, 1939 ー December 19, 2012) was a Japanese manga artist and writer.
He was born in Hiroshima and was in the city when it was destroyed by an atomic bomb in 1945.
All of his family members who had not been evacuated died in the bombing after being trapped under the debris of their house except for his mother, and an infant sister who died several weeks after the bombing.
In 1961, Nakazawa moved to Tokyo to become a full-time cartoonist, and produced short pieces for manga anthologies such as Shōnen Gaho, Shōnen King, and Bokura.
Following the death of his mother in 1966, Nakazawa returned to his memories of the destruction of Hiroshima and began to express them in his stories.
Kuroi Ame ni Utarete (Struck by Black Rain), the first of a series of five books, was a fictional story of Hiroshima survivors involved in the postwar black market.
Nakazawa chose to portray his own experience directly in the 1972 story Ore wa Mita, published in Monthly Shōnen Jump.
The story was translated into English and published as a one-shot comic book by Educomics as I Saw It.
Immediately after completing I Saw It, Nakazawa began his major work, Hadashi no Gen (Barefoot Gen).
This series, which eventually filled ten volumes, was based on the same events as I Saw It but fictionalized, with the young Gen as a stand-in for the author
Barefoot Gen depicted the bombing and its aftermath in graphic detail but also turned a critical eye on the militarization of Japanese society during World War II
and on the sometimes abusive dynamics of the traditional family.
Barefoot Gen was adapted into two animated films and a live action TV drama.
Nakazawa announced his retirement in September 2009 citing deteriorating diabetes and cataract conditions.
He has cancelled plans for a Barefoot Gen sequel.
In September 2010, Nakazawa was diagnosed with lung cancer and in July 2011, metastasis from lung cancer was found.
