Sushi Inukai

If Nagano's headline counter argues that the mountains can answer the sea, Sushi Inukai (鮨いぬかい) in Matsumoto answers a narrower, more local question: which sea? Matsumoto sits in the central basin of the Japanese Alps, and the nearest salt water is not Tokyo Bay but the Niigata coast at Joetsu (上越), roughly three hours north over the mountains. Chef Inukai has built his sourcing around that geography, buying direct from the ports around Naoetsu (直江津) — firefly squid, monkfish liver, snow crab, sweet shrimp landed on the Sea of Japan — and threading them through with Shinshu ingredients. He calls the result Joetsu-Shinshu-mae (上越信州前): a coastline and a mountain province on the same counter.

The chef's road to this room is documented and worth stating plainly, because we do not invent lineages. He left for Tokyo at eighteen to become a sushi craftsman, worked five years in the capital, then trained four more at Suehiro-zushi (末廣鮨) in Shimizu, Shizuoka, before coming home to his father's shop — a neighborhood sushi-ya called Tambo Sushi (たんぼ鮨) — and reopening it under his own name in 2015. The shari reflects that pedigree without copying Tokyo: locally grown Koshihikari from Matsumoto's Shimauchi district, seasoned mainly with rice vinegar and only a whisper of aka-zu (赤酢), a gentler grain tuned to fish that is fresh rather than long-aged.

The recognition has followed. Inukai is the prefecture's second counter to hold a Tabelog Hyakumeiten listing — selected for Sushi EAST in both 2022 and 2025 — carrying a Tabelog mark around 3.77 across more than fifty reviews, a far thicker evidence base than most rural counters can show. The omakase runs generous and nigiri-forward, fifteen-plus pieces in the standard course, with touches that lean into place: apple-wood-smoked squid, miso-pickled local gobo worked into a roll. Plan tiers range from roughly ¥8,800 for a nigiri course to ¥16,500 for the full tsumami-and-sushi omakase.

Two honest cautions. The room seats twenty in total once the private rooms are counted, so the kobako feeling lives at the nine-seat hinoki counter — request it explicitly when you reserve. And the operation is cash only with a 100% same-day cancellation policy, unusually strict, so lock your plans before you commit. This counter is not yet visited; the curation here is database-driven, drawn from the restaurant's listings and third-party reviews. Confirm the current course price, the service terms, and the photography policy when you book.
