SUDA Seishu (1947–) is a master of the Satsuma-biwa and Heike-biwa, traditional Japanese instruments. He was born in Tokyo and studied Satsuma-biwa with Tsuji Seigo and Heike-biwa with Kindaichi Haruhiko. In 1970, he won the Biwa Music Competition and has been a leading performer in the biwa world for over 50 years.

The biwa is a Japanese string instrument with a long history. It came to Japan during the Nara period (710–784 AD) and is thought to have originated in Iran. It is related to instruments like the lute and oud. There are several styles of biwa, such as Gagaku-biwa and Heike-biwa, but this recording features the Satsuma-biwa. This type was created about 500 years ago in Satsuma (modern Kagoshima prefecture) under the orders of a samurai lord, Shimazu Tadayoshi. He asked a blind monk named Fuchiwaki Juchoin to develop it. The Satsuma-biwa grew as the music of the Satsuma samurai class and is known for its strong, simple, and bold style.
