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).

Column
The charm of Ishiyama Kaisen lies in its exceptionally fresh cuisine, a tapestry woven from the bounty of Lake Biwa and the treasures of nearby seas. Our exquisite dishes, made with an abundance of fresh seafood, stimulate the senses and provide an unforgettable dining experience. In particular, our signature straw-grilled skipjack tuna and seasonal seafood delivered directly from the fishing port have won acclaim from many customers for their aroma and flavor.
However, while seeking a wonderful culinary experience, we understand that dining out can sometimes be a source of anxiety for guests with food allergies. Concerns like Does this dish contain an allergen? or Will my request be properly understood? can prevent one from fully enjoying what should be a delightful meal.
In this article, we will detail the measures we take at Ishiyama Kaisen to ensure that guests with allergies can enjoy their dining experience to the fullest. As an izakaya in Keihan Ishiyama and a local pub in Awazu, we will share our commitment and specific strategies for ensuring all our customers can dine with peace of mind and a smile.
For many, the time spent sharing delicious food and conversation with friends and family is a priceless joy. However, for guests with food allergies, dining out can sometimes present a significant barrier. Since it concerns one's health, meticulous care is essential to enjoy a meal with peace of mind.
Questions like Does this dish contain eggs? or Is dairy used? arise with every item. If labeling is inadequate, the available options can become extremely limited.
When conveying allergy information by phone or online, it's natural to worry, Was my message received correctly? or Will they remember? Especially for large groups at an Ishiyama banquet izakaya, there is a concern that individual requests might be overlooked.
Cross-contamination, where allergens mix with other ingredients during preparation, is another major source of anxiety. To eat with confidence, guests must trust the restaurant's thorough hygiene management and cooking processes.
It is our greatest wish to avoid a situation where these anxieties prevent you from truly enjoying the delicious cuisine of Ishiyama Kaisen, forcing you to remain on high alert throughout your meal. As an izakaya in Keihan Ishiyama and a pub in Awazu, we are committed to addressing these issues sincerely to provide the best experience for all our guests.
To ensure you can enjoy Ishiyama Kaisen to the fullest, we have implemented a multi-faceted approach to sincerely address our guests' allergies. We believe that providing meticulous, personalized service is the first step toward ensuring you can dine with us in complete confidence.
Allergy information provided by our guests is instantly shared not only at the time of booking but with all kitchen and floor staff. In addition to verbal communication, we use a dedicated system with specialized sheets to ensure information is relayed accurately. This prevents situations where requests are not communicated and allows all guests to enjoy the cuisine of Ishiyama Kaisen with peace of mind.
Knowledge about allergies is constantly evolving. We conduct regular training for all staff on allergy fundamentals, the risks of accidental ingestion, and emergency response procedures. We strive to operate with the latest knowledge and awareness to accurately answer any questions from our guests.
We carefully manage all ingredients used in our restaurant by checking allergen information sheets from our suppliers. We maintain thorough allergen labeling not just upon delivery but also during storage to prevent the use of incorrect ingredients. While freshness and quality are paramount for our straw-grilled skipjack tuna and port-direct seafood, we manage their allergen information with equal importance.
When preparing meals for guests with allergies, we use separate cooking utensils and cutting boards whenever possible to minimize the risk of cross-contamination. After use, these items are thoroughly washed and sanitized to prevent any impact on subsequent cooking. Despite our limited kitchen space, we prioritize guest safety, and our entire staff is highly conscious of this commitment.
Depending on the guest's specific allergies, we may alter parts of a menu item or prepare a dish from scratch. For example, we can omit certain seasonings or substitute ingredients. As an izakaya in Keihan Ishiyama, this flexibility reflects our dedication to pursuing every single customer's definition of delicious.
In our menus, we strive to list not only the 7 major specified raw materials (egg, milk, wheat, buckwheat, peanut, shrimp, crab) but also the 21 items that are recommended for labeling. This helps our guests choose their meals with confidence. Please do not hesitate to ask our staff if you have any questions.
We are also focused on developing courses and à la carte dishes that avoid specific allergens as much as possible. We are constantly experimenting to meet diverse dietary needs so that all guests can fully experience the charm of Ishiyama Kaisen. As a pub in Awazu, we believe these efforts are essential to remaining a beloved establishment in our community.
Our pride, the Straw-Grilled Skipjack Tuna, is a fragrant masterpiece made by searing fresh tuna in the high heat of a straw fire. Additionally, our seasonal seafood, sourced directly from the fishing port, allows us to offer the best ingredients of the day. We believe that allergy management and safety are just as crucial as freshness for these dishes.
We select seafood sourced directly from fishing ports where the origin and fishing methods are clear. By understanding not only the freshness but also the environment in which the seafood was raised and caught, we reduce the risk of unnecessary additives or allergen contamination. For example, we are especially careful to verify the origin and freshness of certain types of seafood that can cause allergic reactions. This is the foundation of trust at Ishiyama Kaisen.
It is known that as seafood loses its freshness, it can produce histamine and other allergy-like substances. By quickly transporting fresh seafood from the port to our restaurant and managing it under strict temperature control during storage and preparation, we minimize the formation of such substances. This is our commitment to ensuring you can enjoy the taste of Ishiyama Kaisen at its best and safest.
While the straw-grilling method itself is simple and carries a low risk of extra allergen contamination, we have established a dedicated cooking space for it to prevent cross-contamination with other dishes. The skewers, tongs, and other tools used for straw-grilling are always kept clean, ensuring our guests can enjoy their meal with confidence. This thorough management system is our promise of safety as an izakaya in Keihan Ishiyama.
For guests with severe allergies, we may use disposable cooking utensils or specially stored and cleaned equipment upon request. This is a measure we can take with prior consultation to ensure maximum safety. We are particularly vigilant with common allergens like wheat and eggs. As a pub in Awazu, we spare no effort for the sake of our customers' smiles.
A banquet at Ishiyama Kaisen is a precious occasion to deepen bonds with friends and celebrate special moments. Precisely because it involves a large group, we have prepared a flexible system to accommodate individual needs, so that no one with allergies has to feel like they are an inconvenience. As a banquet izakaya in Ishiyama, we promise to provide a venue where both organizers and participants can relax and have fun.
When you make a banquet reservation, we will ask in detail about any food allergies. We don't just ask for the allergen; we also inquire, to the extent possible, about details such as How much of the ingredient triggers a reaction? and What kind of symptoms have occurred in the past? This allows us to consider the most appropriate response. We have a section for allergy information on our online reservation form, and we welcome phone calls as well.
For guests with complex or multiple allergies, a knowledgeable staff member will handle the booking and carefully listen to your situation. Through specific consultations, we can determine if an allergen can be completely removed or if an alternative menu can be offered, proposing a plan that gives you the greatest peace of mind.
If allergy accommodations are needed for a banquet course, we can serve the allergen-free dishes on a separate plate for the concerned guest. This prevents cross-contamination from other dishes and allows them to enjoy their meal without worry. For example, even with our popular hot pot dishes, a staple at our Keihan Ishiyama izakaya, we can provide individual serving dishes or an allergen-free broth.
We also accept requests to replace or remove allergenic ingredients from specific dishes. For a guest with an egg allergy, for instance, we can prepare a special egg-free dessert to ensure the overall satisfaction of the course is not diminished. Even with a simple dish like our straw-grilled skipjack tuna, if the sauce contains a potential allergen, we can suggest an alternative.
It is also possible to review the proposed menu, created based on your allergy information, before the banquet. This helps prevent unexpected issues on the day of the event and allows you to attend with greater confidence. As we use seasonal ingredients direct from the port, the menu may change, but we will inform you of any adjustments as they occur.
For guests with an alcohol allergy or those who wish to abstain from alcohol due to medication, we offer a rich variety of non-alcoholic drinks. You can choose from non-alcoholic beer, cocktails, and fresh juices to suit your taste. As a pub in Awazu, we strive to offer a diverse drink menu that pairs well with the cuisine of Ishiyama Kaisen.
We disclose ingredient information for our drinks whenever possible. Our staff will be happy to provide explanations so that guests who need to avoid certain allergens or are sensitive to specific ingredients can make their selections with confidence.
No matter how dedicated we are to allergy management, we cannot provide a perfect response without accurate information from you. Here are three concrete steps to ensure you can fully enjoy your meal at Ishiyama Kaisen without worry. By following these steps, you can help us ensure you have a wonderful and safe time at our Keihan Ishiyama izakaya.
The most important step is to clearly communicate your allergy information at the time of booking. This allows us to prepare in advance and welcome you with a fully ready team.
If you are booking a banquet at our Ishiyama izakaya, we ask the organizer to collect allergy information from all attendees in advance and provide it to us in one go. This ensures no individual's information is missed and allows for a smooth response.
We also take the opportunity to reconfirm your allergy information when you arrive. This is a crucial step to verify that the information was transmitted correctly and to give you an extra layer of confidence.
If you feel even the slightest bit of uncertainty during your meal, such as Is this dish okay for me?, please call a staff member right away. Your safety is our top priority.
These steps are designed to create a partnership between you and our restaurant, ensuring that even guests with allergies can fully enjoy the delicious cuisine of Ishiyama Kaisen. As a pub in Awazu and an izakaya in Keihan Ishiyama, we sincerely look forward to welcoming you.

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。
