Amakusa Tōjiki is a collective term for diverse ceramics from Kumamoto Prefecture's Amakusa region, boasting over 250 years of history. It's Kyushu's oldest porcelain area and the source of Amakusa Tōseki (Amakusa porcelain stone), considered among the world's finest. This broad category includes exquisite porcelain, fired with Amakusa Tōseki, and rustic earthenware using local clay. Amakusa Tōjiki's defining characteristic is significant stylistic variation among its kilns, such as Takahama Yaki's translucent white porcelain, Uchida Sarayama Yaki's celadon, Mizunohira Yaki's namako-yu (sea cucumber glaze), and Maruo Yaki's rustic red clay pieces. Its superior raw material gained historical acclaim, notably praised by Edo period polymath Hiraga Gennai in 1771. Designated a National Traditional Craft in 2003, Amakusa Tōjiki's enduring quality and diverse artistry are solidified within Japanese ceramic heritage.
