Regularfoot pro surfer from Chiba, Japan; winner of the Japan Professional Surfing Association tour in 1989 and 1990; described by Surfing magazine as "the Japanese Tom Curren."
Kasuya was born (1961) and raised in Chiba, and began surfing at age 15, after becoming one of the country's top skateboarders. In 1980 he was Japan's second-ranked men's division amateur surfer; the following year he moved to Huntington Beach, California, and turned pro, returning to Chiba every three months because he didn't have a work visa.
A fast, lithe, athletic surfer, Kasuya competed sporadically and with no great success on the world pro tour in the mid - and late '80s. On Japan's domestic pro tour, however, he was in the top five from 1982 to 1987, champion in 1989 and 1990, and remained in the top 10 until late 1997. A near-fluent English speaker, Kasuya worked for Dropout Surfboards—one of Japan's biggest boardmakers—as an interpreter and liaison to the American and Australian surf worlds. He also worked for Surfing Life, a Japanese magazine, as well as Hurley International, and in the 2010's became a surf coach—one of his clients was Hiroto Ohhara, who in 2015 became the first Japanese surfer to with the US Open.
Kasuya appeared in a small number of surf movies and videos, including Blazing Boards (1983), Asian Paradise (1984), and Freeze Frame (1989). Shuji Kasuya's Stylish Surfing, a Japanese-made instructional video, came out in the early 1990s.
Kasuya has lived in Honolulu, Hawaii, since 1986.
