Gunma

Gunma is one of Japan’s fully landlocked prefectures, and there is no honest way to write around that. The ji-no-ri axis — the advantage of place, worth thirty of our hundred points — is structurally capped here, because there is no local boat, no morning port, no thousand-meter canyon dropping away from the shore. Every fish that reaches a Gunma counter has traveled. The question this changes is not whether to eat sushi in Gunma, but why — and the answer the best counters give is craft and procurement rather than geography.

That reframing is the whole point. In a coastal prefecture, the chef’s edge is the water at the doorstep. Inland, the edge has to be earned: a relationship with a market, a willingness to source widely, the patient handwork — curing, nikiri, aging, warm shari — that turns shipped fish into Edomae. Gunma’s counters are an argument that distance from the sea need not mean distance from the craft, and a handful of them make it convincingly.

When to come

Without a local catch, Gunma’s calendar follows the markets its chefs buy from rather than a bay outside the door, which paradoxically makes the season broader — a chef sourcing through Toyosu and direct shipments can reach for the best of several coasts at once. Winter still rewards the trip most, when cold-season fish run rich and a warm counter is its own argument against the Joshu karakkaze, the dry mountain wind that defines a Gunma winter. Spring and autumn bring the shellfish and white-fleshed fish at their fullest. There is no single headline ingredient the way Toyama has its shiro-ebi — here the draw is the chef, not the catch.

How to use the corridor

Gunma’s counters cluster in two areas, both easy off the Shinkansen. Takasaki (高崎), the prefecture’s transport hub and a stop on the Joetsu and Hokuriku Shinkansen, holds the two counters this guide leans on: Sushi Tetsuya, a ten-seat all-counter Edomae house run by a chef who came up the Isesaki fishmonger’s route, and Sushi Shintaro, an eight-seat flat-counter room where a self-taught chef works the entire process in the open. Both sit a short walk or taxi from Takasaki Station and are the easiest serious sushi to reach in the prefecture.

A short hop west into Maebashi (前橋), the prefectural capital, adds Nakazawa — a five-seat hideaway where the owner-chef works alone to soft jazz, omakase only, about as quiet and wabi-sabi as a counter gets. East, in the old silk town of Kiryu (桐生), Edokko Sushi makes the landlocked case most literally: an owner who travels to Toyosu in person and pulls direct shipments from three coasts, though it is a larger house and you should request the counter explicitly.

A note on honesty and planning. None of these counters has been visited by our team; the curation here is database-driven and says so on every entry. Prices, photography policies and the tax-included course figure shift — confirm all three when you reserve, using the booking script in our guides. And keep proportion: the most celebrated Gunma counter, Sushi Obana in Tatebayashi, sources extraordinarily from Toyosu but runs around ¥40,000, beyond this guide’s ¥30,000 ceiling, so it sits outside our recommendations by price alone. Gunma will not give you the bay. What its better counters offer instead is the quieter pleasure of watching a chef earn, far from the water, what a coastline would have handed him for free.
