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.

Column
To all the organizers planning a large-group banquet in Ishiyama, we understand the hard work you put in. Whether it's a company year-end party, New Year's gathering, farewell or welcome party, an important get-together with friends, or a family celebration, these large events are special occasions for all attendees. For the organizer, there's a strong desire to make it a success. However, from choosing a restaurant and selecting dishes to managing the budget and coordinating the event on the day, the list of things to consider can be overwhelming.
Especially with a 'large group,' concerns like 'Will the food quality suffer?', 'Can we provide dishes that satisfy everyone?', and 'Can we secure a spacious private room?' often arise. We listen sincerely to these concerns from organizers and strive day and night to deliver the best banquet that exceeds your expectations. Despite our convenient location right near Keihan Ishiyama Station, we offer a tranquil space where you can forget the hustle and bustle and enjoy your banquet to the fullest.
In this article, we will detail the secrets to hosting a successful large-group banquet in Ishiyama from the perspective of our 'commitment to ingredients.' By the time you finish reading, we are confident you will feel that 'this is the restaurant I can trust with my important banquet.'
If any of these apply to you, please read on.
When planning a large-group banquet, the worries and anxieties for organizers are endless. Naturally, you want everyone who attends to say, 'That was fun,' and 'The food was delicious.' Here, we'll highlight some common 'problems' we hear and offer our perspective and hints for solving them.
We often hear concerns like, 'Even if there are many dishes in a large-group banquet menu, isn't the quality of each one low?' or 'It feels like much of it is pre-made and lacks care.' This is especially disappointing for customers who come expecting high-quality Ishiyama seafood. At our restaurant, our motto is to serve every single dish with heartfelt care, precisely because it's for a large group. We use an abundance of fresh fish delivered direct from the fishing port and carefully selected seasonal ingredients, prepared by our skilled chefs. Therefore, we strive to ensure that even large parties can enjoy a level of satisfaction that is equal to, if not greater than, that of our individual customers.
For a large-group banquet, securing a space where all participants can relax comfortably is crucial. If tables are too close together or you're bothered by the conversations of other guests, it's hard for your own conversations to flow. A private space where you can talk without worrying about your surroundings is particularly sought after for important company celebrations in Ishiyama, business dinners, or even for use as a private date-night izakaya in Ishiyama. We offer a variety of private rooms of different sizes to suit your group size and purpose, accommodating even the largest of banquets. Each room is highly private, allowing you to enjoy conversation and your meal to the fullest in a calm atmosphere.
For a banquet organizer, budget management is an extremely important task. You want to avoid situations where additional charges are incurred later or where unclear billing leads to complaints from participants. To ensure our customers can enjoy their banquet with peace of mind, we clearly present the prices for our set course meals and all-you-can-drink plans. We can also flexibly adjust the content to match your budget, so please don't hesitate to consult with us. As an Otsu izakaya, we want to be a restaurant trusted by our local community.
Preparing for a banquet and managing it on the day can be a significant burden for the organizer. Especially with a large group, gathering requests from participants and making detailed arrangements with the restaurant takes time and effort. To lighten the organizer's load as much as possible, our dedicated staff will provide meticulous support from the reservation stage all the way through to the day of the banquet. Please feel free to ask us about anything, from the content of the dishes and types of drinks to seating arrangements and consultations for surprise presentations. As a drinking spot in Awazu, we are here to assist our local customers with their needs.
To make a large-group banquet in Ishiyama a success, the 'quality of the food' is the ultimate deciding factor. The many exquisite dishes we proudly serve, packed with our commitment to quality ingredients, will surely transform your gathering into an unforgettable event. Herein lies the essence of our Ishiyama izakaya.
The foundation of our cuisine is, without a doubt, fresh seafood. Every morning, we source the day's catch direct from our partner fishing ports across the country. By bypassing the market, the seafood is delivered to our restaurant in the shortest possible time, allowing us to maintain the 'outstanding freshness' that is the true pleasure of Ishiyama seafood. Even when catering to a large group banquet, which requires a large volume of fish, we make no compromises and deliver the highest freshness and quality in every single dish.
Our signature dish, synonymous with our restaurant, is the famous straw-grilled bonito (Katsuo no Warayaki). The dynamic grilling process, with fragrant smoke and towering flames, fills the venue with energy and excitement. This live, performance-like presentation offers the ultimate entertainment for a large-group banquet.
In addition to seafood, as a local Otsu izakaya, we actively incorporate seasonal vegetables grown in the rich soil of Shiga, as well as brand-name Omi meats. By using an abundance of seasonal ingredients, we offer colorful banquet cuisine that is full of the feeling of the season.
For large-group banquets, a comfortable space and attentive service are just as important as the quality of the food. Our capability to handle large-group banquets in Ishiyama should be a great source of reassurance for any organizer.
Here are some concrete steps for organizers to follow to ensure the smooth planning of a large-group banquet in Ishiyama. Following these points will bring you much closer to a successful event.
First, clarify the purpose of the banquet, the number of participants, the budget, and the desired type of cuisine to narrow down your list of potential restaurants. Especially for large groups, the size of the space, the availability of private rooms, and accessibility are crucial.
Once you've chosen a restaurant, it's time to make a reservation. Communicating detailed information and coordinating closely with the restaurant at this stage is the key to success.
Once the reservation is complete, begin preparations for the day of the event. This extra effort will significantly reduce the organizer's burden on the day.
To host a successful large-group banquet in Ishiyama, choosing the right restaurant is paramount. We will grace your banquet table with our specialty dishes, featuring fresh seafood delivered direct from the fishing port and our aromatic straw-grilled bonito. As a Keihan Ishiyama izakaya, we offer an exceptionally accessible location, private rooms suited for various group sizes, and a meticulous support system to ease the burden on organizers.
Whether it's an important company celebration in Ishiyama, a welcome or farewell party, a fun gathering with friends, or a memorable family celebration, we promise to deliver an experience that exceeds your expectations for any occasion. We invite you to experience the true essence of an Ishiyama large-group banquet at our restaurant, where we are fully committed to the taste of our food, the comfort of our space, and the quality of our hospitality.
For an organizer, a successful banquet is a great joy, and for the participants, it becomes an unforgettable memory. We would be honored to help you create that precious moment. As an Otsu izakaya and a drinking spot in Awazu, we continue to strive to be a restaurant loved by all. 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。
