Iwashita Seitou – Handcrafted Mashiko Pottery
Iwashita Seitou is a historic Mashiko-based pottery studio with a lineage spanning six generations. Known for its warm, handcrafted ceramics inspired by nature and everyday life, the studio continues its tradition under the craftsmanship of 6th-generation potter Iwashita Muneaki. Using traditional Mashiko-yaki techniques, Iwashita Seitou creates pieces with gentle forms, natural glazes, and a playful charm—often featuring animals or organic shapes. Each piece reflects the deep ceramic heritage of Mashiko while offering a modern, approachable style loved by collectors of Japanese craft.
Mashiko-yaki (ware) is a style of Japanese pottery originating from Mashiko, a town in Tochigi Prefecture known for its rich clay and centuries of ceramic tradition. Characterized by thick, durable clay, simple yet elegant forms, and natural glazes, Mashiko-yaki is both functional and artistic, perfect for everyday tableware or collectible pieces.
Unlike ultra-delicate ceramics, Mashiko-yaki emphasizes sturdiness, warmth, and a tactile feel, reflecting the hands-on approach of the artisans. Many pieces are handmade in family-run studios, preserving traditional techniques while experimenting with contemporary designs.
