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.

Among the many establishments, finding a truly satisfying one can sometimes be challenging. Especially when you search for Ishiyama Seafood, you might wonder where to choose. Whether it's a meal with loved ones, a banquet with friends, or your own luxurious time, it's natural to wish for a memorable and supreme experience.
At our restaurant, we promise to deliver an unparalleled seafood experience that will exceed your expectations. Our skilled chefs meticulously and creatively prepare fresh seafood, delivered daily directly from the fishing port. Among our offerings, our signature Seared Bonito over Straw, which stimulates all five senses, has been highly praised by many customers. Beyond just delicious food, we also value providing a comfortable space and heartfelt hospitality for all our guests.
In this article, we will delve into the appeal of our chef's recommended course, designed to maximize your Ishiyama Seafood enjoyment, our commitment to quality, and how to utilize our restaurant for various occasions. After reading this, you'll surely feel that when it comes to seafood in Ishiyama, this is the only place. So, why not open the door to a blissful seafood experience?
Our Chef's Recommended Course, which we proudly present, is truly an exquisite dish that condenses the essence of Ishiyama Seafood. Our chef pours immense passion into selecting the freshest fish in their prime condition each day and expressing the changing seasons on the plate. You will feel the harmony of nature's bounty and artisanal skill with every bite.
Japan's four seasons bring abundant blessings from the sea. At our restaurant, we prioritize serving seasonal seafood that can only be enjoyed during its peak. Delicate flavors of cherry sea bream and Spanish mackerel in spring, the rich aroma of conger pike and rock oysters in summer, the fatty umami of returning bonito and Pacific saury in autumn, and luxurious seafood like crab and pufferfish in winter. The course content changes daily depending on the day's catch, but the chef personally visits the market to carefully select ingredients, ensuring they are always served in their best condition. From appetizers to sashimi, grilled dishes, simmered dishes, fried dishes, and finally a concluding dish, the course is thoughtfully balanced, with each plate telling a story.
Our chef approaches cooking with reliable techniques cultivated over many years of experience and a deep love for ingredients. Even the knife work for preparing fish is breathtakingly beautiful. The degree of doneness, the balance of seasoning, and the beauty of presentation—each element is infused with the desire to provide guests with the best possible experience. We constantly strive to maximize the natural flavors of the ingredients, adding no unnecessary touches, yet finishing with an exquisite balance that is never too simple. Please enjoy the chef's passion embedded in each dish with all five senses.
Among our menu items, our signature Seared Bonito over Straw particularly captivates many customers. The sight of bonito dancing in the flames, enveloped in fragrant smoke, is truly magnificent. Sight, smell, hearing, taste, and touch—a special experience that stimulates all five senses awaits you here. Many customers travel from afar just to savor this dish. Please try our proudly seared bonito over straw at least once.
Seared bonito over straw is a traditional cooking method where the surface of fresh bonito is quickly seared with a blazing straw flame. The straw flame reaches a very high temperature but burns out quickly, resulting in a miraculous finish where the bonito's surface is deliciously seared while the inside retains its fresh, raw texture. The unique rich aroma of straw deeply infuses into the bonito flesh, and with one bite, that savory aroma passes through your nasal passages, and a lingering umami spreads throughout your mouth.
While seared bonito over straw is best enjoyed simply, we also suggest ways to make it even more delicious. Feel free to combine it with various condiments according to your preference.
Please try various combinations to find your perfect way to enjoy seared bonito over straw.
The root of the deliciousness of the seafood dishes we offer undoubtedly lies in their freshness. We go to the fishing port every morning, seeking the highest freshness worthy of the Ishiyama Seafood signboard. Fish and shellfish landed that very morning arrive on your table the same day. This is the true essence of our seafood, an experience you won't find anywhere else.
The phrase direct from the fishing port symbolizes our commitment to freshness. It is thanks to our long-standing relationships with trusted fishermen that we can always procure seafood in its optimal condition. Fishermen painstakingly cultivate and catch the bounty of the sea, and we prepare it with heart. It is this connection that allows us to deliver reassurance and感動 to you. Our chef personally selects ingredients, judging by the firmness of the flesh, the amount of fat, and above all, their liveliness. We never compromise, sourcing only the finest ingredients.
It's often thought that fresh fish is best as sashimi, but our chef excels at bringing out new charms through various cooking methods while utilizing its freshness. For example, seasonal white fish, when grilled until plump, highlights the crispiness of the skin and the umami of the flesh. Fatty fish, when simmered, becomes incredibly tender, and its compatibility with the sweet and savory sauce is outstanding. Furthermore, fresh bigfin reef squid and sweet shrimp, when made into tempura, enhance the natural sweetness of the ingredients and offer a light texture.
Our cuisine is not just about arranging ingredients. It's about discerning the unique character of each seafood and serving it to customers in its most delicious state. That is our unwavering commitment to seafood cuisine. Please experience the infinite possibilities woven by seasonal fresh fish at our restaurant.
Our restaurant is highly regarded not only for its delicious seafood but also as an Ishiyama Banquet Izakaya that can be utilized for various occasions.

Delicious seafood cuisine requires excellent drinks to accompany it. As an Awazu Bar, our restaurant offers a rich selection of carefully chosen drinks that further enhance the flavors of our dishes. From sake, shochu, and wine to local beverages, we have a wide lineup to suit your preferences.
In particular, sake pairs exceptionally well with fresh seafood.

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。
