Shinichi Sekizawa

Shinichi Sekizawa (関沢新一) (born in Kyoto, Japan June 2, 1921, died November 19, 1992) was a Japanese screenwriter. His very first screenplay was for the Shintoho Studios film Fearful Attack of the Flying Saucers, which is now considered to be lost. He went on to script several films by Ishirō Honda, including several classic Godzilla films. He also contributed material to the original Ultraman series.

His scripts for kaiju films have been noted for their inventiveness and for having a more lightweight, "fun" tone than those written by Takeshi Kimura (aka Kaoru Mabuchi), another leading writer of kaijyu films, whose scripts had a darker, more serious sensibility.

Before embarking on his screenwriting career, he briefly attended an animation school with famed manga artist and animator Osamu Tezuka.
