Nihonbashi Otako

Nihonbashi Otako is the honten, the original flagship, of one of Tokyo's oldest oden houses, still simmering the same soy-dark broth it began building in 1923. The shop itself has moved once since then — from its original Ginza address to this Nihonbashi corner in 2002 — a detail regulars still mention when they explain why a "century-old" restaurant sits in a fairly modern building.

The dish everyone comes for is tomeshi: a bowl of soy-seasoned rice crowned with a single block of tofu that has spent hours soaking in that dark dashi, arriving soft enough to collapse under chopsticks and tasting far deeper than its plain appearance suggests. Order it alongside a rotating lineup of Kanto-style oden — daikon, hanpen, chikuwa — simmered all day in the same pot, and you're effectively tasting a stock that has never been fully emptied and restarted. The building is part of the draw: a ground-floor counter for solo diners watching the oden pots simmer, table seating on the second and third floors, and tatami seating upstairs for groups.

A few practical notes before you go. It's cash only — no cards, no e-money — in keeping with the ¥¥¥ range. Reservations are accepted only for parties of three or more, and even then seatings run on a strict two-hour clock; solo and duo diners simply show up and take a counter stool on a first-come basis. The menu now carries English (plus Chinese and Korean) translations, so ordering isn't a guessing game even without Japanese. Go early on a weeknight if you'd rather skip the wait — this is a Nihonbashi institution locals still queue for, a century of continuously topped-up broth notwithstanding.
