Soba Dokoro Miyoshi is a hand-rolled soba restaurant in Kusatsu Onsen, Gunma, located within the Agatsuma District at one of Japan's most celebrated hot spring resorts. The restaurant focuses entirely on buckwheat soba made from locally sourced Gunma buckwheat flour, stone-ground at low temperature to preserve the flour's natural oils and the earthy, slightly nutty flavour characteristic of high-altitude grain. The buckwheat used is grown in the cooler, well-drained highlands of Gunma, which produce grain with a robust flavour profile. Soba is rolled and cut to order during service; the kitchen maintains a short daily supply to ensure freshness. Cold zaru soba — chilled noodles served on a bamboo tray with a concentrated soy-mirin tsuyu dipping sauce and a small mound of wasabi and chopped negi — is the house standard and the most ordered preparation; it allows the grain flavour of the noodle to be tasted without competition from broth. Hot kake soba with mountain vegetable tempura adds a bowl of warm dashi and a seasonal tempura topping. Duck dipping soba (kamo nanban-zuke) — noodles served with a separate heated broth infused with duck fat and slices of roast duck — is a more elaborate and flavourful option suited to autumn and winter visits. The dining room is simple and unadorned: wooden tables, washi paper screens, and natural light from a single street-facing window. The atmosphere is calm and appropriate to the contemplative pace at which good soba is meant to be eaten. Reservations are not taken; visitors who arrive at opening time generally secure a table without waiting.

Frequently asked questions
What is the difference between zaru soba and kake soba?
Zaru soba is served cold on a bamboo tray with a separate cold dipping sauce; kake soba is served hot in a bowl of warm dashi broth. Zaru better showcases the buckwheat noodle flavour; kake is more warming and substantial.
Are gluten-free diners catered for?
Buckwheat is naturally gluten-free, but the tsuyu sauce contains soy (which includes wheat); cross-contamination may occur in a shared kitchen. Visitors with severe gluten sensitivity should inquire directly.
What is sobayu?
Sobayu is the water in which the soba noodles were cooked. It is customarily added to the remaining tsuyu dipping sauce after the noodles are finished and drunk as a warm, starchy drink — a gesture of appreciation to the buckwheat.
Is the restaurant easy to find in Kusatsu?
It is located on the main road of Kusatsu Onsen within walking distance of the Yubatake; a small wooden signboard with Japanese script marks the entrance.
