虎屋 壺中庵

His phrase is “deliciousness that doesn’t overreach”: broths built on kelp and salt, soy sauce used in drops, a spareness critics compare to ink‑brush painting. The wan — the clear‑soup course by which any kaiseki kitchen is judged — holds a crab dumpling in that ringing broth, and it is what regulars cross the country for. In summer he serves ayu — sweetfish, the river fish of the Japanese summer — that he catches himself, from rivers whose individual flavors he tells apart; wild eel he has hooked becomes a closing tea‑rice. Autumn is matsutake, the pine mushroom; winter, mountain venison. Gault & Millau has kept him at three toques for five straight years.

The mechanics are strict and simple: reserve by phone in Japanese (088‑679‑2305) or on Ikyu’s Japanese‑language booking page, no later than the day before (cancellations cost 100% from three days out), and everyone starts together — lunch at 12:00, dinner at 18:00, one seating each, roughly three parties a night in private rooms. Arrive late and the meal has left without you. The booking, though, is the easy half. Sanagochi has no train, no bus worth planning around, no taxi rank; the restaurant sits 30–⁠40 minutes by car from Tokushima City. What actually needs arranging is the driver, the timing against your flight, and the call itself — one Japanese phone conversation that fixes the date, the course, and any dietary notes, which is precisely the package our desk assembles.
