About
Tsukushinbo operated in Seattle's Japantown for nearly 30 years under founder Masayoshi Caccam, who was born in Kawasaki, Japan. When the original restaurant closed in 2022, his children Marin and Sho stepped in to honor the legacy with Onibaba in 2023, located in the same space. Sho Caccam leads the sushi counter while the menu focuses on handcrafted onigiri (yaki onigiri, tuna mayo, unagi, ebi mayo), ochazuke, donburi, agedashi tofu, and curry. The restaurant operates without reservations and draws consistent queues from Japantown regulars who cherish the family's three decades of community stewardship.
