Ginrin (銀輪, "Silver Ring") is Toshio Matsumoto's first film.
Matsumoto made it in 1955 as an English-language PR film, although "a relatively avant-garde" one.
The film score was the first by Toru Takemitsu.
It was believed lost for many years; however, a copy has been recently found and digitally restored by the National Film Center of the National Museum of Modern Art, Tokyo.
