Onibaba by Tsukushinbo is a beloved Japanese restaurant in Seattle’s Japantown, highly acclaimed for specializing in two Japanese comfort food staples: onigiri (stuffed rice balls) and ochazuke (steamed rice with a savory dashi broth).1
Here is a detailed breakdown of the restaurant, its history, unique features, and customer information.
What Makes Onibaba Unique
Onibaba distinguishes itself by moving beyond the typical Japanese fare of ramen and sushi, focusing instead on traditional, home-style cuisine with a cozy, welcoming atmosphere.2
- The Onigiri Focus: As “Seattle’s Onigiri Hotspot,” the restaurant offers nearly 20 varieties of freshly prepared, generously stuffed rice balls, ranging from classic flavors to unique modern takes.3
- The Culinary Heritage: It is the spiritual and physical successor to the legendary restaurant Tsukushinbo, which had operated in the same location for decades.4 Onibaba carries the family’s legacy and preserves popular classics from the original menu, most notably the highly praised katsu curry.5
- The Name: The restaurant’s name, Onibaba, is a clever, multi-layered reference.6 It’s a combination of the Japanese words for “oni” (demon) and “baba” (hag), and is also a play on the word onigiri.7
- The Ambiance: Customers consistently describe the dining area as warm and cozy, creating a perfect environment for enjoying Japanese comfort food.8
History
The history of Onibaba is intrinsically tied to the family’s first restaurant, Tsukushinbo.9
- Tsukushinbo’s Legacy: The Caccam family’s parents founded the original restaurant, Tsukushinbo, in 1994.10 It gained a loyal following over nearly three decades.
- The Transition: After Tsukushinbo closed, siblings Marin and Sho Caccam transformed the space and officially opened Onibaba by Tsukushinbo in 2023.11 The new concept focuses on onigiri and ochazuke while incorporating beloved rice bowl classics from the predecessor, allowing the family to continue their culinary tradition in Seattle’s Japantown.12
