© 2026 UOMARU YASU
Our story
Located in the heart of Yasu, Shiga, Uomaru is a seafood izakaya where fresh fish and carefully selected sake meet the craft of robatayaki grilling.
Sashimi finished by skilled hands from fish delivered straight from the port, bonito from Kochi, and Omi beef from Shiga — grilled dynamically right before you over straw and charcoal.
A calm Japanese space with lively counter seats and relaxing private rooms — for dates, family dinners, and company banquets alike.
Commitment
In spring, young 2-3kg first-catch bonito; in autumn, richly fatty 4-5kg returning bonito, carefully selected by season.
Most Kochi bonito is pole-and-line caught, leaving it beautiful and undamaged. We ship our select bonito direct from the port.
We use straw hand-cut ourselves from vast contracted fields in Shiga. Dried straw burns hot with the finest smoky aroma.
Over straw flames reaching 1000 degrees, we sear a crust about 5mm into the flesh, then finish with residual heat to lock in flavor.
Cut over 1cm thick so the straw aroma fills your mouth, brimming with bonito flavor and a springy texture.
A fully sun-dried salt handmade by artisans from Kochi seawater. We select larger crystals for a mellow mineral taste.

How to enjoy Robata
How to enjoy straw-grilling and robata
Thirteen counter seats, twelve table seats, eight in the private room and twelve on the terrace: 45 in all. In a room this size, the flames and the crackle of the straw reach every seat.
The finished surface carries the smoke of burning straw. Leave the first slice unseasoned and taste the natural sweetness underneath.
Later in the plate, shift with condiments, rock salt and citrus. Winter brings kanburi yellowtail, whose fat loosens and lightens against salt and citrus.
Every seat, including the twelve on the terrace, allows smoking. Our staff suggest Shiga sake, dry through sweet, to match your sashimi or straw-grilled dish.

接客が丁寧で好感持てる。 料理も美しく、提供も丁寧でもちろん全部美味しい。 たまたまかもしれないが、厨房含め女性中心に運営されてるのかな。どうでもいいことかもしれないけど。

木曜日に行きましたがお店はお客さんで賑わっていました。 漁港直結の今朝獲れのお刺身は新鮮で美味しかったしキレイな盛り付けにテンション上がりました。 人気のポテサラはたっぷりのいくらと、とびこのプチプチ感がたまりませんでした。 ホッケも肉厚で美味しかったです。 帰り際にお店の方から小袋に入ったふりかけのお土産をいただきました。 一つ一つメッセージも書かれてて嬉しかったです。 とっても満足な時間を過ごせました。 ぜひまた行きたいと思いました。
