Getting there
Asakusa (Tsukuba Express) 2 min / Tawaramachi 5 min — beside Kappabashi kitchen town
Dojō — the loach, a finger‑length freshwater fish — was Edo’s protein
of the people: cheap, faintly sweet, cooked in shallow iron pans with
burdock root and heaps of scallion. Asakusa once had dozens of
specialist houses; a handful remain, and Iidaya, established 1902 with
roots in a rice shop of the 1860s, is the connoisseur’s pick. The
novelist Kafū Nagai kept his seat here. A doorman still receives your
shoes at the entrance — a house rule holds that the master’s job is
the broth and the front door — and the sweet‑soy warishita, the
seasoned simmering broth, is known by family law to exactly one person
per generation.
What you eat
Loach whole or boneless, simmered at your table in that secret broth
and buried — the staff will insist — under a full box of raw scallion,
then dusted with sanshō, Japan’s tingling mountain pepper, from the
Yagenbori shop that has ground spices since the 17th century. The
kinder gateway dish is yanagawa: boneless loach and burdock bound in
softly set egg. Pots run about ¥2,000–2,100; with drinks, sides, and
the okami’s (proprietress’s) own nuta — a miso‑vinegar dressed dish
whose recipe is another one‑person secret — a full evening lands
On tatami, with an English menu on the table.
The booking reality
The house takes bookings by telephone only and pointedly refuses the
reservation apps — walk‑ins seat easily at off‑hours across its two
floors of shared tatami, but the sunken‑hearth private room (5–8
guests, ¥2,000 room fee), the annex for groups up to about twenty, and
any peak evening all run through a Japanese phone call. Note the
closing day: Wednesdays, but shifted around holidays and Asakusa’s
festival calendar, which is precisely the sort of thing a desk
confirms in one local call before you cross town.
Are ready to go one dish deeper than sushi, are already headed to
Kappabashi’s knife shops next door, or believe — correctly — that the
humblest specialties keep the oldest secrets: this is what the
carpenters of this city ate for three centuries, at the price of a
chain izakaya.
Free release-date alerts: the day before, on the morning of release day (08:00 JST) and about 30 minutes before when the time is known — or a weekly summary if the house opens a little every day.
