Kosakuya

Kosakuya sits a short walk from Kawaguchiko Station in Fujikawaguchiko and is one of the area's better-known spots for hoto, Yamanashi Prefecture's signature dish of thick, hand-cut flat wheat noodles simmered directly in a miso-based broth with kabocha squash, carrot, mushroom, and other seasonal vegetables until the noodles thicken the soup itself. The restaurant occupies a rustic, farmhouse-style building with wooden beams, floor cushions, and an irori-style hearth feel, giving diners a sense of Yamanashi's mountain-village dining tradition rather than a modern noodle-shop setting. The single iron pot the hoto is cooked and served in keeps the dish piping hot throughout the meal, which matters given how cool the lakeside air can turn even in summer evenings. A pork-based butajiru hoto variant and, in season, grilled ayu river fish round out an otherwise tightly focused menu. Reservations are not required, though the small dining room can fill around midday with visitors moving between Lake Kawaguchiko sightseeing stops. Prices are modest, typically ¥1,000 to ¥2,000 for a full bowl, and the restaurant is an easy stop before or after the Kawaguchiko ropeway or a lakeshore walk.
