Kundō Koyama (小山薫堂) (born 1964) is a Japanese writer. He is best known for scripting the television series Iron Chef and the 2009 Academy Award for Best Foreign Language Film recipient Departures. Koyama has also worked under the pen name Udon Kumayakko, an anagram of his real name read backwards in Japanese.
Koyama was born in 1964 in Hondo (now part of Amakusa), Kumamoto, Japan. His father, Kiyotsugu, worked in finance, while his mother, Takako, owned a beauty parlor. He has a brother named Shōdō (将堂) three years younger than him who has Down syndrome; Koyama says their parents strove to raise them equally. As a child Koyama considered becoming a poet, but did not follow through.
As a broadcasting student at the Nihon University College of Art, he began working under Yasuji Hayashi of Nippon Cultural Broadcasting. Hayashi, who found him an "interesting character", asked Koyama to begin writing scripts for broadcast. In Koyama's third year he branched out into television screenwriting, making his debut with the late-night show 11pm. Continuing this screenwriting after graduation, Koyama began getting attention for his work on Fuji Television's Kanossa no Kutsujoku (1990–1991), a late-night show which "took various modern-day social phenomena and products and explained them satirically by presenting them as historical events and folklore".
Koyama later wrote Nippon Television's Susume Denpa Shonen, and Fuji's Iron Chef. In 2003 he wrote an International Emmy Award-nominated series, The Perfect Manual.
In 2008 Shochiku hired Koyama to adapt Aoki Shinmon 's autobiographical Coffinman: The Journal of a Buddhist Mortician (納棺夫日記 Nōkanfu Nikki); this was Koyama's first venture in the feature film industry. Koyama dropped many of the books religious themes, changing them with more humanistic ones, and integrated a subplot from a novel he was writing. For the title he coined the term okuribito, a euphemism for morticians derived from the words okuru ("to send off") and hito ("person"). The final film, Departures, was submitted to the 81st Academy Awards for the Best Foreign Language Film and won, the first Japanese win in the category. For his writing, Koyama received numerous accolades, including a Kinema Junpo Award,Yomiuri Prize, and Japan Academy Prize. By December 2009 the film had won 98 awards.
