He was best known for his memoirs Coffinman: The Journal of a Buddhist Mortician,[2] published in 1993. The book was based on his diaries during a period in which he worked as a mortician in the 1970s, a profession which is traditionally regarded as a taboo in Japan due to their perception of death. In 2008 his memoirs were adapted into a successful Academy Award-winning feature film, Departures, by filmmaker Yōjirō Takita.[3]
