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.

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).

Life is full of special moments that deserve to be etched in memory: a loved one's birthday, a couple's anniversary, a party to celebrate a major success at work, or an important business dinner to discuss the future. On such days, everyone wishes to provide a memorable hospitality experience that is a cut above the usual. A delicious meal sparks conversation, creates a warm atmosphere, and above all, becomes deeply engraved in people's memories.
However, many people wonder, Where can I find a place to create such a special day? You don't want to compromise with ordinary food or a generic atmosphere; you want to find a restaurant that offers true satisfaction. This choice can feel especially challenging if you are seeking the freshest gifts from the sea.
To meet those expectations, our restaurant offers the finest port-direct seafood and warm, heartfelt hospitality. Why not create a special evening with us at our Ishiyama izakaya? In this article, we will detail the secrets to making the most of our port-direct appeal to enhance your special day, and introduce the various plans we offer.
What comes to mind when you hear the phrase port-direct? It means more than simply getting fresh fish; it holds a deeper significance and has the power to dramatically enhance your dining experience. Unlike seafood that goes through typical distribution channels, our unique route of sourcing directly from fishermen allows us to serve seafood so fresh it's as if it's still alive.
Seafood loses its freshness and flavor over time. The journey from the port to the market and then to a retailer inevitably takes time, during which the fish's umami components gradually change. However, our port-direct practice minimizes this time loss to the absolute extreme. Fish that is caught arrives in our kitchen the very same day or the next. This speed allows us to deliver the fish's inherent umami and texture to you without compromise.
This port-direct philosophy is the key to transforming your special day from simply a delicious meal into a moving and memorable culinary experience. We invite you to savor the true essence of Ishiyama seafood at our restaurant.
We offer a variety of plans that make the most of our fresh, port-direct seafood, tailored to our customers' various special occasions. As an Ishiyama izakaya, we are dedicated to helping you create wonderful memories with our attentive service and exceptional cuisine.
For a date or anniversary with someone special, the atmosphere is key. We offer private rooms with a calm ambiance where you can enjoy your time together without interruption. From the lighting and BGM selection to the seating arrangement, we strive to create a space where conversation flows naturally. Our gorgeous platters of fresh, port-direct fish are a feast for the eyes and a perfect conversation starter.
For celebration parties marking business success or for dinners with important clients, the quality of the food and the thoughtfulness of the hospitality are what determine success. We provide our guests with an exceptional experience through course meals featuring high-quality ingredients and meticulous service. Thanks to our port-direct sourcing, we can also propose special plans that include rare seafood and premium fish you won't often encounter.
Tips for a successful celebration or business dinner in Ishiyama:
For large banquets such as company farewell parties, year-end gatherings, or large get-togethers with friends, it's essential to provide a space and cuisine that satisfy everyone. We offer spacious seating where large groups can dine comfortably. Our generous course menus, packed with fresh port-direct seafood, are sure to bring a smile to everyone's face.

5種盛り合わせの焼きとりは味付濃くて美味しかったです! スタッフ全員も親切で親とゆっくり過ごせました。
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。
