Harmonica Yokocho retro tiny restaurants in Kichijoji ハーモニカ横丁 Tokyo with Adeyto

Retro Showa style, this place was first built as a flea market in the early postwar years, this collection of alleys on the north side of Kichijoji Station is now best known for its more than 100 small but excellent restaurants, which began popping up in the late '90s, lined up in a small area that looks like the mouthpiece of a harmonica. You'll also find grocery and clothing stores here, along with specialist shops for goodies like yokan (sweet bean jelly), pork cutlet and taiyaki (fish-shaped pancakes filled with anko bean paste). The bustle is turned up at night, when diners crowd the trendy standing-only bars and miniature eateries. For the complete experience, try spending an entire night bar-hopping without exiting the harmonica-like maze.
It's nestled between large shopping building and arcades in the area. The adjacent covered arcade called Runroad is also packed with shops and restaurants. This area is easy to get to from most anywhere in Tokyo and expect to spend many hours in the area.
