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.

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.

Column
Ishiyama, located in Otsu City, Shiga Prefecture, on the shores of Lake Biwa. For all who wish to indulge in exquisite food and fine sake to their heart's content, we propose a special way to spend your time at an Ishiyama izakaya. This time, we will focus particularly on the seasonal delicacies that change with each passing season, sharing the secrets to an unforgettable culinary experience.
The joy of experiencing the blessings of the changing seasons with all five senses and encountering a special dish that can only be tasted at that time is irreplaceable. We hope that for you, our Ishiyama izakaya will become not just a place to fill your stomach, but a place where memorable stories are born.
Among the many izakayas, finding one where you can truly encounter delicious seasonal dishes can sometimes be difficult. Have you ever looked at a menu and found it hard to tell which ingredients are at their peak, or how they are prepared? If you're going to make the trip, you want to taste a special dish unique to that season. To meet such desires, we will delve into the charms of seasonal cuisine and the key points for choosing a restaurant.
To solve the common concerns of many customers, such as I don't know what's in season or I'm not sure what to choose, we constantly strive to offer the best of the season. We hope this column will serve as a compass for you to discover the finest seasonal tastes at an Ishiyama izakaya.
The greatest pleasure at an Ishiyama izakaya is undoubtedly the ability to fully enjoy the blessings of each season. In this land surrounded by the rich nature of Lake Biwa and Omi, it is a culinary treasure trove where the bounties of the sea and mountains intersect. We devise new ways every day to serve these blessings in their most delicious form.
Spring brings an abundance of delicate ingredients that make you feel the breath of new life. The slight bitterness of wild mountain vegetables and the faint sweetness of seafood color the dining table. At our Ishiyama izakaya, we offer a variety of seasonal tastes that herald the arrival of spring.
In the hot summer, refreshing yet nutritious ingredients whet the appetite. At our Ishiyama izakaya, we offer a well-balanced menu of dishes that evoke a sense of summer coolness and powerful flavors to boost your stamina.
The harvest season of autumn is when the umami of ingredients is most concentrated. Deep flavors and rich aromas characteristic of the season further stimulate the appetite. At our Ishiyama izakaya, we prepare dishes that allow you to feel the arrival of autumn with all five senses.
In the cold winter, one craves rich-tasting dishes that warm you from the core. Fatty fish and slow-simmered hot pots are the true delights of an Ishiyama izakaya in winter.
What we value most of all is freshness. Freshly caught seafood is sent directly from various fishing ports every morning and arrives at your table the same day. In particular, our signature straw-grilled bonito is a moving dish born from this freshness and skill.
Leveraging the strength of being direct from the fishing port, we bypass the market to source our seafood, allowing us to offer our customers fish that was just caught this morning. This is a commitment we cannot compromise on in our pursuit of deliciousness.
Our straw-grilled bonito is not simply grilled. Following the traditional cooking method of Kochi Prefecture, fresh bonito caught by pole-and-line is boldly seared over a roaring straw flame. In this moment, the flame and smoke unite, enveloping the surface of the bonito with a unique, fragrant aroma.
In addition to straw-grilled bonito, we offer fresh seafood direct from the fishing port in various forms.
Delicious food is, of course, best accompanied by good sake. As an Otsu izakaya and Awazu bar, we also focus on the local sake that Shiga Prefecture prides itself on. Born from rich water and rice, local sake pairs exceptionally well with seasonal dishes. As one of your options for a Keihan Ishiyama izakaya, please consider our restaurant, which is particular about its food and local sake pairings.
Local sake is also a mirror reflecting the climate and culture of the land. The Japanese sake born from the rice grown in Shiga's rich nature and the water of Lake Biwa truly has a taste unique to this region. With a spirit of local production for local consumption, we propose pairings that make the most of local blessings.
We propose pairings that maximize the personality of each local sake and the flavor of seasonal ingredients.
As a Keihan Ishiyama izakaya, we pursue pairings of local cuisine and sake that make the most of our local charm.
The dining experience is not just about tasting food. We take care to ensure that the entire flow, from the moment a customer steps into the restaurant until they leave, becomes a special, memorable time. As an Ishiyama izakaya, we stimulate our customers' five senses not only with the taste of our food but also with our space, our tableware, and our spirit of hospitality.
We aim to provide a warm, comfortable space and service that makes our customers feel they want to come back again. Through our cuisine, we hope you will feel the beauty of the seasons, Japanese culture, and the connection between people.
Food is something to be enjoyed with the eyes. We are also particular about our presentation, utilizing the colors and shapes of the ingredients to express a sense of season. Each dish is as beautiful as a painting, whetting our customers' appetites.
To ensure our customers have the best possible time, we value the spirit of hospitality. We value communication with our customers, not just serving food and drinks, and strive to provide a pleasant time.

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。
