Soba Kura Annaka is a specialist handmade soba restaurant near JR Annaka Station in Annaka City, western Gunma, producing a daily-limited quantity of juwari soba — noodles made from 100% buckwheat flour without any wheat flour binder, a technically demanding preparation that requires skill to prevent the fragile noodles from breaking during kneading and cutting. The 100% buckwheat format produces noodles with a more pronounced earthy, nutty flavour and a more delicate texture than the more common hachi-ni (80% buckwheat, 20% wheat) blends; the trade-off is that juwari soba must be handled carefully and consumed quickly after cooking. The buckwheat used is stone-ground on-site each morning from grain sourced from Gunma's Agatsuma highland farms. Cold zaru soba — chilled and served on a bamboo tray with concentrated tsuyu — is the standard presentation and the vehicle through which the buckwheat flavour is clearest. Duck dipping soba (kamo nanban) presents the noodles alongside a small pot of heated duck broth infused with rendered duck fat; the intense, aromatic broth contrasts effectively with the clean buckwheat. Soba with grated yam (tororo soba) adds a viscous, starchy topping that softens the noodle's dryness. The kura in the restaurant's name means storehouse — the dining room occupies a converted Edo-period storehouse with thick plaster walls and wooden shelving that creates an atmosphere of historical weight. Natural light through narrow windows, exposed beams, and minimal decoration complete a dining environment that foregrounds the soba rather than the surroundings.

Frequently asked questions
What makes juwari soba different from ordinary soba?
Juwari soba uses 100% buckwheat flour with no wheat binder; this produces more pronounced buckwheat flavour and a delicate texture, but the noodles are more fragile to make and must be eaten promptly. Most commercial soba contains 20–30% wheat flour for structural stability.
How is the kura storehouse building?
The converted Edo-period warehouse has thick plaster walls, wooden beams, and original shelving that create a quiet, atmospheric dining room very different from a modern restaurant interior.
Is advance reservation needed?
Walk-in is the norm but early arrival (by noon) is essential. Groups of five or more should call ahead (+81 27-385-2277) to confirm that sufficient daily soba remains.
What is Annaka City known for?
Annaka is at the western entrance to Gunma Prefecture; the city is associated with the Shinetsu Highway, the historic Nakasendo post road, and proximity to the Usui Pass where Gunma meets Nagano.
