Kasuga Zushi

To understand a Kofu sushi counter you first have to unlearn the Toyama logic of zero-mile fish. Yamanashi is fully landlocked, ringed by mountains, and yet it has long held the highest number of sushi shops per capita of any prefecture in Japan. The explanation is a single old word: uojiri-ten (魚尻点), the "fish-tail point" — the furthest a catch from Suruga Bay could be carried in the Edo and Meiji eras before it turned. Kofu sat almost exactly on that line. Fish that arrived was no longer pristine, so the town's craftsmen learned to cure rather than rely on freshness — to shime with salt and vinegar, to marinate as zuke, to coax flavor from material that had already begun to travel. That necessity became a culture, and a hunger: in a place without a coast, sushi became the definition of a feast.

Kasuga Zushi is a small, deliberate keeper of that tradition. It sits on Ginza-dori, the old main street of central Kofu, behind an unshowy front, and it works in akazu — red vinegar, the darker, rounder, more historically Edomae seasoning — rather than the bright white rice of the modern style. Reviewers describe an elderly chef of evident conviction, with his son now standing the late shifts, the kind of two-generation handover that quietly decides whether a counter survives its founder. Seven seats at the counter, a handful of tables behind. This is a room, not a stage.

The honest caveat is that Kasuga is not a Tokyo-priced omakase temple, and you should not arrive expecting one. The listed budget sits in the ¥5,000 to ¥10,000 range, payment is cash only, and the hours run late into the night in the manner of a neighborhood shokunin who serves regulars as much as travelers. There may not be a single fixed "omakase course" so much as a chef who will take care of you if you let him — so phone ahead, ask him to lead, and confirm the evening's format and the tax-inclusive total at booking. Photography policy is unconfirmed; ask quietly before you raise a camera.

Frame this counter for what it is: not the prefecture's most expensive seat, but perhaps its most articulate. If you want to taste why a mountain province fell in love with sushi — the curing hand, the red vinegar, the feast-day reverence for fish that had to be worked to be worth eating — Kasuga is the argument made in seven seats. It is database-recommended, not visited; the curation here rests on its Tabelog standing and the consistent testimony of its reviewers, and it says so plainly.
