Ise Gen (いせ源) is Tokyo’s longest-running restaurant specializing in ankō (anglerfish), serving its signature dishes in a beautifully preserved wooden building from 1930 that is now a designated historical property. The experience revolves around the 名代あんこう鍋 (nadai ankō-nabe), a rich, soy-based hot pot that showcases the fish.
Diners consistently praise the quality of the ankō, especially the kimo (liver), which is served either cooked or as creamy kimo-sashi (raw liver sashimi). The kitchen skillfully uses every part of the fish, from the skin to the roe, often as part of multi-course meals. The meal traditionally concludes with ojiya, a savory rice porridge made with the remaining broth from the pot. While the attentive staff and atmospheric tatami rooms are highlights, some guests have noted that service can feel rushed and the broth's strong, sweet flavor may not suit all palates. Seating can also feel cramped during busy periods.
Despite its premium pricing, most find Ise Gen offers good value for a unique and expertly executed meal. Expect dinner to cost between ¥10,000 and ¥14,999 per person. Reviewers recently paid ¥10,000 for the 'Minamoto' course and ¥12,000 for the 'Irodori' course. A la carte items include kimo sashimi for around ¥1,800 and the ankō-nabe for about ¥4,000. Note that a 10% service charge is added in the evening, and choosing chair seating incurs an extra fee.
