Oyatsupan began as an "austere" Japanese bakery in Beaverton, according to Portland Monthly, and has expanded to include other locations in The Portland metropolitan area, including Tigard and southeast Portland.
The menu has included "whimsical "chocolate pudding stuffed cornets, croissant dough apple pies with matcha custard, and doughnuts filled with Japanese beef curry, as well as eclairs, Japanese breads, pastries, and sandwiches. In 2018, Grant Butler of The Oregonian wrote, "This airy, elegant bakery combines Japanese and Western baking traditions, resulting in pastry cases filled with baked goods you expect (croissants, baguettes, puff pastry) with things you don't see at other places (green tea cookies, Japanese sweet buns, buttery rolls filled with edamame or red bean paste). There are savory options, too, like the unusual hot dog roll, which features a wiener baked into a brioche bun, and dressed up with drizzles of ketchup, mayonnaise and mustard."
The bakery opened in May 2016. Hiro Horie is the chef and owner. In 2019, a second location called Oyatsupan Bridgeport Village opened in Tigard. The business began operating a kitchen in southeast Portland in 2026.
