Izumoya Annex
Powered by Google
The annex building of Nihonbashi Izumoya, a venerable eel specialist founded in 1946. Where the main building draws crowds for its limited daily special (10 portions of premium unajuu from 11:00), the annex offers a slightly more accessible entry point — with walk-in table seats on the ground floor and traditional tatami-style private rooms upstairs that share the same menu as the flagship. Skilled craftsmen prepare eel in four distinct styles: kabayaki (the classic), shiro-yaki (salt-grilled, with wasabi and soy), seiryu-yaki (brushed with house fish-sauce and grilled), and the rare kaba-no-ho-yaki using an ancient whole-skewer technique. The stock begins with premium katsuobushi and top-grade Rausu kombu every morning.
