Born in Hagi City, Yamaguchi Prefecture, in 1951, Miwa Kyusetsu XIII is the third son of Miwa Kyusetsu XI (Miwa Jusetsu). In 1975, he moved to the United States to study at the San Francisco Art Institute. Years later, upon returning to Japan, he began working at the family kiln, Fusoan Miwagama, developing a highly distinctive body of work that pushes traditional Hagi-ware beyond its established forms.

Grounded in the tradition of Hagi stoneware and the Miwa family's characteristic ash-white glaze, known as Kyusetsu white, his work is marked by striking contrasts between unglazed clay surfaces and thick, crawling glazes that bead and break, revealing the red clay beneath.

In May 2019, he formally assumed the title Miwa Kyusetsu XIII, following his brother's retirement. Kyusetsu XIII has received both national and international recognition, including the Japan Ceramic Society Award in 2007 and a Gold Award 2021. His work is represented in leading collections worldwide, including the Museum of Fine Arts, Boston, the Los Angeles County Museum of Art, and the National Museum of Modern Art, Tokyo.
