Tabelog ratingIshimame (いし豆) is a tiny, house-like restaurant in the Hokkaido countryside, run by an elderly couple dedicated to one thing: exceptional soba. What makes it special is the raw material: rare, black-Matsunai buckwheat, which they mill by stone on-site. This produces a noodle with a distinctively firm, slightly gritty texture and a powerful aroma that has earned the shop a loyal following and a place in Japan's 'Tabelog 100' list of top soba restaurants.
Guests consistently praise the signature torigobou, a dish of cold soba served with a hot dipping broth of chicken and burdock root. The limited-batch sobagaki, a mochi-like dumpling of pure buckwheat, is another highlight, as are the generous portions and the thick, flavourful sobayu (the hot water used to cook the noodles) served at the end of the meal.
The main drawback is the difficulty of getting a seat. With only 12 spots and a reputation that precedes it, waits of one to two hours are common, and the shop often sells out of its 35-40 daily servings by early afternoon. A few diners note that the uniquely coarse texture of the noodles may not be to everyone's taste, but most agree the quality is undeniable.
Reviewers report a typical spend of ¥1,000–¥1,999 for a meal. Recently, the popular torigobou was around ¥1,400, a simple mori soba was about ¥1,100, and the highly sought-after sobagaki cost between ¥700 and ¥1,200. Visitors overwhelmingly feel the quality justifies both the price and the wait.
