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.

Column
Choosing the right restaurant is key to a successful gathering, whether it's a meal with a valued client or a special celebration with friends. The pressure to not make the wrong choice and ensure everyone is happy is especially strong for important business dinners, milestone anniversaries, romantic dates, or large-scale after-parties. Here in Ishiyama, we have the perfect place to meet these expectations and create lasting memories. Our star attraction is the straw-grilled bonito, a dish that stimulates the senses with its powerful aroma and brilliant flames. We offer this exquisite taste, born from a traditional cooking method, along with a special atmosphere and warm hospitality.
Is this really the right place? This is a thought many of you likely have when planning an important meal or event. For a business dinner, you want your guests to be comfortable and feel respected. For an anniversary, you want to see your partner smile. For a date, you want a romantic atmosphere that brings you closer. For a large party or after-party, you need a place where everyone is satisfied and the organizer can relax. However, finding one izakaya among many that fits the bill for each scene is a challenge. The quality of the food, the ambiance, the availability of private rooms, the service, and the budget—few establishments meet all these criteria at a high level. We know that those searching for terms like Ishiyama party izakaya, Ishiyama after-party, Ishiyama date izakaya, Ishiyama large group party, and Ishiyama izakaya are looking for concrete solutions. We are fully prepared to be the best choice to meet these expectations.
In particular, among the seafood dishes that represent Japanese culinary culture, our straw-grilled bonito offers a special experience right from its preparation. The sight and smell of the straw bursting into magnificent flames stimulates the senses and whets the appetite. But it's not just about novelty; the taste must be authentic. From here, we will introduce our commitment to quality and provide concrete answers to your questions about what makes truly delicious straw-grilled bonito and how we elevate it into a special experience.
Our straw-grilled bonito is more than just a dish; it is an experience that stimulates the five senses and creates lasting memories. For those searching for an izakaya in Ishiyama, we will fully convey the charm of this one item, hoping it becomes the deciding factor in your choice.
The greatest appeal of straw-grilling is, without a doubt, its aroma. We use generous amounts of carefully selected dry straw, searing the bonito at a high temperature in an instant. This smokes the surface, imparting a unique, savory fragrance that can never be achieved with conventional grilling methods. The skin becomes crisp and aromatic, while the inside remains moist and rare, sealing in the umami. One bite releases the rich aroma of the straw, followed by the deep, inherent flavor of the bonito. This multi-layered taste is truly a supreme experience.
By searing the surface instantly with high-temperature flames, the bonito's umami components are locked in, maximizing the fish's natural deliciousness along with its rich aroma. At our restaurant, skilled chefs perform this process carefully by hand, adjusting the heat according to the condition of the bonito each day. We strive to always serve it to our customers in its best possible state.
The foundation of delicious straw-grilled bonito is, above all, its freshness. We carefully select and source only the freshest bonito in its peak season. This freshness highlights the contrast with the savory aroma of the straw, allowing you to enjoy the firm yet melt-in-your-mouth texture of the fish. To maximize the flavor of the straw-grilling, we pay meticulous attention to freshness management, ensuring it remains in perfect condition until the moment it reaches your table.
For special occasions like client dinners and anniversaries, the restaurant's atmosphere and service are just as important as the food. Here is how we meet your expectations when you plan such events in Ishiyama.
To ensure our guests can cherish their private time, we offer various types of private rooms. From quiet dinners with a few people to mid-sized anniversary celebrations and important dates, you can choose the perfect space for your occasion.

The counter is a prime spot where you can experience the aroma of the food up close and watch the bustling kitchen.

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。
