OKA Onigiri
OKA Onigiri is a fast-casual onigiri concept founded by Kaoru Iriyama, which opened in 2025 in Mitte on Oranienburger Strasse. The format centers on onigiri made fresh to order, with a broad selection of around 20 savory and sweet varieties. Fillings range from tuna mayo and salmon to ume, mustard greens, sukiyaki beef, shrimp, and wasabi. Designed for quick visits, the space offers counter seating and small tables, with most orders suited for takeaway.
Our favorite is the tuna mayo and ume Onigiri
