Tabelog ratingTatsunami Ichiban (立浪一番) is a local legend, a restaurant that has perfected a single dish: a magnificent chanko nabe (a sumo wrestler's hotpot) called the Yokozuna Kinboshi Nabe (横綱金星鍋). The experience is as much theatre as it is dinner. Staff take full control, cooking each ingredient for you at the table and telling you the precise moment to eat it. The meal unfolds in stages, with the dashi broth deepening in flavour as enormous clams, prawns, octopus, chicken, and vegetables are added and served.
Diners consistently praise the rich, evolving broth and the quality of the ingredients, especially the house-made sardine tsukune (meatballs). Other highlights include the addictive fried tofu puffs (matsuyama-age) and the satisfying finale of either gooey mochi and udon noodles or a savoury zōsui rice porridge cooked in the remaining broth. The strict rules, however, are a recurring theme. The restaurant enforces a 60-minute time limit and a cap of two drinks per person, and requires a reservation call just 30 minutes before arrival. While most regulars embrace this as part of the unique experience, some first-time visitors find it rushed. A few also note the broth can become very salty by the end, and isolated reports mention hygiene concerns over staff handling ingredients with bare hands.
Despite the rules, most reviewers consider it excellent value. Diners in 2024–2026 reported paying around ¥3,800–¥3,850 for the hotpot set. Add-ons like matsuyama-age cost about ¥400, and the final zōsui course was ¥495–¥550. A typical meal with drinks came to ¥5,000–¥6,000 per person.
