Izumoya

With unagi mamushi, the sauce flavours the rice as well as the eel. Visitors explain that the name “mamushi” refers to rice coated with sauce, topped here with eel grilled Kansai-style without steaming. Diners have described the eel as fragrant, with tender flesh, and the sauce as clean-tasting and restrained in sweetness. The sauce-soaked rice is on the soft side, and its appeal lies in how it comes together with the eel. For those used to Tokyo-style eel rice bowls, the different grilling method and flavour of the rice are part of the experience.

Liver soup and rolled omelette are worth considering alongside the unagi mamushi. One report mentions a generous piece of liver in the soup, while the broth itself offers another flavour to enjoy. Several diners ordered the rolled omelette with eel; it is an option if you would like another dish with your meal or are choosing something to accompany a drink. Menu listings also mention eel-filled rolled omelette, pickles and bottled beer.

Izumoya is in Higashikohama, Sumiyoshi Ward, near Sumiyoshi Taisha Shrine. Diners have reported eating in and ordering takeaway. As dishes are prepared after ordering, one visitor said the wait was around 30 minutes. Allow extra time, particularly around the busy lunch period. The atmosphere is described as quiet, and the restaurant is presented as suitable for dining alone. Listings say that payment is cash only, so it is worth preparing before you go.
