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.

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).

Column
A Large Group Banquet in Ishiyama is a gathering with dear ones. Whether it's a company welcome/farewell party, a family celebration, or a long-awaited reunion with friends, dining with a large group can create an unforgettable time for all participants. However, for the organizer, selecting a venue and menu that will satisfy every guest can sometimes be a significant source of worry. Beyond the quality of the food and the variety of beverages, the most crucial factor determining a banquet's success is the ability to offer a truly special experience.
At our restaurant, we propose a secret to elevate your Large Group Banquet in Ishiyama from a mere meal to a moment filled with culinary discovery and delight. That secret is the marriage of fresh seafood and wine. While Japanese sake has traditionally been considered the classic pairing for Japanese cuisine, especially fish dishes, wine actually pairs exceptionally well. Why not enrich your banquet even further with this fresh approach?
While the lively atmosphere of a large group banquet is undoubtedly appealing, do you ever feel it tends to be uniform or lacking something? Let's explore some common dilemmas customers face when organizing large group banquets:
Drinkers and non-drinkers, meat lovers and fish lovers, those who prefer sweet and those who prefer spicy... As the number of participants grows, selecting dishes and beverages that cater to each individual's taste becomes an extremely difficult task.
There's a tendency to choose safe, standard course menus, which often results in an ordinary banquet. Many guests express a desire for new discoveries or surprises, especially when it's a special occasion.
Have you ever experienced a situation where the food was delicious, but the drinks didn't pair well, or vice versa? Without overall harmony, even the most delicious dishes lose half their appeal.
It's challenging to create an atmosphere and an overall experience that feels special, going beyond simply enjoying good food.
To address these challenges and ensure guests genuinely feel, I want to come again, and That was a wonderful banquet, our restaurant offers a new perspective: wine pairing. We invite you to discover how this approach can bring enhanced satisfaction and delight to your Large Group Banquet in Ishiyama.
To create a truly memorable experience where all participants can wholeheartedly enjoy their Large Group Banquet in Ishiyama, we propose wine pairing. Let's explore some exceptional culinary marriages made possible by Ishiyama's abundance of fresh seafood.
Our Ishiyama Seafood boasts the bounty of Lake Biwa and fresh catches delivered directly from across Japan. Its delicate flavors are an exquisite match for white wine.
The beauty of translucent flesh and the aroma of the sea that spreads in your mouth. For white fish and shellfish in particular, dry white wines rich in sharp acidity and minerality, such as Sauvignon Blanc or Chablis, are perfect. The wine's refreshing quality enhances the inherent umami of the fish and cleanses the palate. This combination is ideal for kicking off a large group banquet at an Izakaya in Keihan Ishiyama.
For seafood whose umami is concentrated by cooking, such as fragrant grilled sea bream with salt or plump steamed crab dishes, a rich Chardonnay with subtle oak notes pairs wonderfully. It also goes well with dishes using butter or cream, where the seafood's flavor and the wine's complexity enhance each other.
Our Straw-Grilled Bonito (Katsu no Warayaki) is one of our signature dishes. Seared rapidly over a straw flame, it develops a fragrant, crispy exterior while remaining wonderfully moist inside. Surprisingly, red wine reveals an exceptional affinity for this dish, characterized by its unique aroma and rich umami.
The fragrant smokiness of the straw, the rich umami of the bonito, and the refreshing zest of the garnishes. For this complex flavor profile, a lighter red wine with low tannins and abundant berry fruit, like Pinot Noir, is an astonishingly good match. The wine's tannins harmonize with the bonito's fat, drawing out its rich flavor while leaving a clean finish. This innovative pairing is sure to be a particularly memorable experience among Ohtsu Izakayas.
For those who find red wine a bit too heavy, rosé wine is also highly recommended. In particular, a fruity yet dry rosé enhances the flavor of straw-grilled bonito without overpowering it, adding a vibrant touch. Its elegant aroma stimulates the appetite and brings a bright atmosphere to any large group banquet.
Beyond seafood, seasonal delicacies nurtured by Shiga's rich natural environment, such as fresh seasonal vegetables and local specialty dishes, are also a major draw of the Large Group Banquet in Ishiyama. For these offerings, we provide an even richer regional experience by pairing them with Japanese wines, which have recently garnered significant attention, or with local sake from Shiga.
For example, delicate Japanese wines made from Japanese grape varieties, which complement traditional Japanese cuisine, pair excellently with dishes showcasing the sweetness of Omi rice or fresh seasonal vegetables, such as tempura or simmered dishes. Japanese cuisine, which emphasizes drawing out subtle flavors and respecting the natural taste of ingredients, and Japanese wine are truly an ideal combination.
Of course, traditional Japanese sake, especially local sake crafted with Shiga's abundant water and rice, also pairs exceptionally well with seafood. While wine pairing is our main focus, we also offer a carefully selected range of local sakes for those who prefer it. As an Awazu bar, it is our pleasure to meet diverse needs.
When you hear wine pairing, you might feel it sounds difficult or wonder which one to choose. Please rest assured. Our restaurant boasts staff with extensive wine knowledge. We will suggest the optimal wines, tailored to the purpose of your Large Group Banquet in Ishiyama, the details of your course menu, and the preferences of all your guests.
For example, if you consult with us in advance, we can provide a curated list of wines to complement your course menu or even suggest a truly special bottle. Your only task is to relax and thoroughly enjoy the exquisite food and wine. Our experts' insights will guide your banquet to an even richer experience.
Wine pairing transforms your Large Group Banquet in Ishiyama from a mere meal into a special, deeply memorable experience. Our proudly served dishes, such as fresh Ishiyama Seafood and fragrant Straw-Grilled Bonito, gain even greater brilliance with wine as their new partner. For customers seeking an Ohtsu Izakaya, a Keihan Ishiyama Izakaya, or an Awazu bar, this unique banquet style offered by our restaurant is sure to bring fresh surprise and delight.
To ensure both organizers and all participants are truly satisfied and smiling, we extend our heartfelt hospitality. Please feel free to inquire and make reservations. Our entire staff sincerely looks forward to making your Large Group Banquet in Ishiyama an unforgettable and wonderful day.

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。
