Founded in 1891, Asakusa Sushisei is the oldest shop on Asakusa's historic Sushiya-dori, a narrow street lined with long-standing sushi restaurants. The dining room centers on a nine-seat hinoki wood counter, with a quiet tatami private room available for up to eight guests. The chef builds a fully reservation-only omakase around whatever the day's best catch offers, favoring seasonal Edomae-style nigiri. The calm, understated interior and no-perfume policy set a refined, focused mood for savoring the fish course by course.
