Shinichi Sekizawa

was a Japanese screenwriter noted for his immense contributions to several films by Ishirō Honda, including several classic Godzilla films. He also contributed material to the original Ultraman series and several Tōei Dōga films such as Gulliver's Travels Beyond the Moon and Jack and the Witch.

His first screenplay was for the independently produced film (though distributed by Shintoho Studios) Fearful Attack of the Flying Saucers, which was also his sole directing credit.

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 kaiju films, whose scripts had a darker, more serious sensibility.

Before starting his screenwriting career, he shortly attended an animation school with famed manga artist and animator Osamu Tezuka.
