In 1956, he was designated as a Living National Treasure by the Japanese government for his katazome stencil dyeing technique.

A leading member of the mingei movement founded by Yanagi Sōetsu, Serizawa visited Okinawa several times and learned the Ryūkyū bingata techniques of dyeing.

[2] His folk-art productions included kimono, paper prints, wall scrolls, folding screens, curtains, fans, and calendars.

[3][4] He also produced illustrated books, including Don Quixote,[5] Vincent van Gogh and A Day at Mashiko.

[9] "The distinguishing trait of Serizawa's katazome method is the use of the starch mixture to create, not a colored area as is current in direct-dyeing process, but a blank, undyed one that forms a part of the pattern and that can later be colored by hand in multi-color or monochrome as the designer sees fit.
