Having spent three years in
St Ives with Bernard Leach, he returned to Japan in 1923 and traveled to potteries and stayed at Tsuboya in
Okinawa Prefecture for weeks, then eventually established his workshop in
Mashiko, about north-east of Tokyo. Here, he built his own pottery and committed himself to using only locally sourced materials, not only in the clay he used, but also the glazes he created and the brushes he manufactured himself from dog hair and bamboo. In 1955 the Japanese government designated him "
Living National Treasure", the first time for someone from the field of crafts. The previous year on 29 May 1954, the
Cultural Property Protection Act had been amended, and a new Preservers of Important Intangible Cultural Properties (Jūyō Mukei Bunkazai Hojisha) designation was passed the bill in November for its criteria and approval details. Following Yanagi Muneyoshi, Hamada was enthusiastic about folk art movement in Japan. When Yanagi died in 1961, he succeeded as the second director of the
Japanese Folk Crafts Museum, and in 1977, he opened his own museum at his home, Mashiko Sankōkan (present Shoji Hamada Memorial Mashiko Sankokan Museum), and exhibited his collection of folk crafts from Japan and abroad. Hamada Shoji was very supportive of young artists who moved to Mashiko such as his student
Shimaoka Tatsuzō, and
Kamoda Shōji, and was also important in establishing Mashiko as a destination for day tourism. He provided housing and hosted workplace for visiting potters from abroad as well. Hamada died in Mashiko on January 5, 1978. == Preserving local architecture ==
