Our story
Located by Ishiyama Station in Otsu, 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 table and sofa seating — 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 Kohoku, northern 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
About a minute on foot from the south exit of JR Ishiyama Station, and about a minute from Keihan Ishiyama Station. Once inside the 78 seat room, go and stand where the straw flames rise.
The bonito is shipped direct from Tosa-Saga port in Kochi. Begin at the smoke-wrapped surface, with nothing added, and confirm the sweetness of the fish itself.
Change the flavor for the second half. Straw-grilled Omi beef from Shiga also finishes lighter with rock salt and a squeeze of citrus.
Counter, table and sofa seats, plus an open terrace. Cigarettes are allowed on the terrace only, and it suits a drink after a walk along the Seta River or the Seta no Karahashi bridge.
Producers

Saga is where the Kuroshio current first meets Japan, a town thriving on pole-and-line bonito fishing and one of Kochi's foremost fishing towns.

A genuine sun-dried salt made using only the sun's heat, with painstaking care. Entirely handmade, it grows into crystals that melt in the mouth, the very finest sun-dried salt.

Ishiyama
About a 1-minute walk from the south exit of JR Ishiyama Station, and about a minute from Keihan Ishiyama Station too. At 4-9 Awazu-cho, Otsu, we serve seafood straight from the port with robatayaki and straw-grilling across 78 seats.
The backbone is straw-grilled bonito sent from Tosa-Saga port in Kochi (medium, about two portions, 1,490 yen / 1,639 yen incl. tax) and the selected five-kind sashimi platter of fish gathered from across Japan (1,290 yen / 1,419 yen incl. tax). Straw-grilled Omi beef from Shiga is also on the menu (1,690 yen / 1,859 yen incl. tax).
We offer nine banquet courses with two hours of free-flow drinks, from 4,500 yen including tax — Uomaru Casual (6 dishes, 4,500 yen) and Uomaru Standard (11 dishes, 5,000 yen), through charcoal-grilled Omi duck and Omi beef, up to the Omi beef sukiyaki course at 10,000 yen. Full-venue bookings from 50 guests are also possible.
We do not. We seat you according to your party size among the 78 counter, table, sofa and open-terrace seats.
Both JR Ishiyama and Keihan Ishiyama stations are about a minute away, so you can come straight from Ishiyama-dera, the Seta-no-Karahashi bridge or a stroll along the Seta River. With two stations to choose from, it is easy to meet whether you come from Otsu and Zeze or from Kusatsu and Minami-Kusatsu.
Smoking is separated: paper cigarettes may be smoked on the terrace only. Please check with our staff on arrival for details.
The service charge is 5% (waived when you order a course), and we take cash, major credit cards and PayPay. There is no dedicated car park, but with both the JR and Keihan stations about a minute away, coming by train is easiest. We are open daily 17:00–24:00 (food L.O. 23:00, drinks 23:30).

初めて友達に連れてきてもらいました。 店員さんオススメのももみはジューシーアツアツでめちゃくちゃ美味しいです! 他の焼き鳥も美味しくてまた来たいと思いました!
焼き鳥とレバーの火入れ加減が好みです。 バスクチーズケーキもおすすめ。 今後も通いたい! たまに新人のかたへのシビアな指導がきこえるのが気になる。
焼き鳥も美味しく、〆のラーメンも美味しかったです! バイトのコたちの接客も気持ちよくて、外観も入ったところも雰囲気とても良かったんですが 個室と頼んだ2階が、ほんとに民家の2階の座敷という感じで、、 雰囲気台無しでとても残念でした😢 もう少し2階も考えたほうがいいかな?と思いました〜
焼き鳥がとても美味しいお店でした。 塩胡椒がしっかり効いていて、素材の旨みが引き立ってお酒が進みます! 特にこころはぷりっぷりで、弾力のある食感が印象的でした。 店内の雰囲気も落ち着いていて、打ち上げやデートにもおすすめできるお店だと思います。 またぜひ伺いたいです。
