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.
Producers

Ishiyama
About a 1-minute walk from the south exit of JR Ishiyama Station, and about a minute from Keihan Ishiyama Station too. At 4-9 Awazu-cho, Otsu, we serve seafood straight from the port with robatayaki and straw-grilling across 78 seats.
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.
The service charge is 5% (waived when you order a course), and we take cash, major credit cards and PayPay. There is no dedicated car park, but with both the JR and Keihan stations about a minute away, coming by train is easiest. We are open daily 17:00–24:00 (food L.O. 23:00, drinks 23:30).

Column
Welcome to our izakaya in Keihan Ishiyama! Our goal is to provide everyone with delicious food and a wonderful time, making the most of the bounty of Lake Biwa and its rich ingredients. However, in recent years, we've noticed an increase in customers with food allergies and have heard that some hesitate to dine out. It is truly unfortunate for us when a wonderful culinary experience is marred by anxiety over allergies. That is why today, we, as a Keihan Ishiyama izakaya, would like to explain in detail the measures we are taking to ensure our customers can enjoy their meals with peace of mind.
If you've ever felt that dining out is difficult because of my allergies or it's lonely not being able to eat the same thing as everyone else, please rest assured. We are sincerely dedicated to ensuring that every single customer can gather around the table with a smile. Please enjoy your special time at our Keihan Ishiyama izakaya with complete confidence.
Dining out adds color to daily life and is an important opportunity to deepen connections with others. However, for those with food allergies, this opportunity can sometimes be accompanied by great anxiety. Especially at an izakaya, which handles a wide variety of ingredients, concerns like I don't know what's in the food or I'm worried about cross-contamination may be endless. We deeply understand the anxieties our customers face. With a strong desire for everyone to enjoy our cuisine with peace of mind and to their heart's content, our Keihan Ishiyama izakaya is seriously committed to handling food allergies.
So that everyone can smile in a delicious and enjoyable dining setting, we take the utmost care at every step—from sourcing ingredients to cooking and serving our customers—to protect the dietary safety of each individual. We strive daily to make our Keihan Ishiyama izakaya a special, memorable place, even for those with allergies.
In this column, we will clearly explain the specific measures we are taking and how we ask for your cooperation. What we value most is communication with our customers. If you have any concerns or requests, please do not hesitate to let us know.
High-quality ingredients are the foundation of our cuisine. At our Keihan Ishiyama izakaya, we leverage our strength of sourcing direct from the fishing port to offer an abundance of fresh seafood. This port-direct system not only ensures superior freshness but also gives us the advantage of easily obtaining detailed information about our ingredients. The first step in our allergy management starts right here, with the selection and control of our ingredients.
We always prioritize customer safety and approach each and every ingredient with sincerity. We want all our customers to safely enjoy the delicious taste of our fresh, port-direct ingredients. That is the wish of our Keihan Ishiyama izakaya.
A commitment to ingredients alone does not complete our allergy management. It is essential to conduct a meticulous consultation based on each customer's specific allergy information and to accurately communicate that to the kitchen. At our Keihan Ishiyama izakaya, we place the utmost importance on communication with our customers and have established a system to ensure they can enjoy their meals with peace of mind.
In addition to avoiding allergens, it is extremely important to prevent unintentional mixing, or so-called cross-contamination. In our kitchen, we are committed to the following practices to provide safe dishes.
These initiatives are just a part of our significant efforts to ensure our customers can enjoy the cuisine of our Keihan Ishiyama izakaya with peace of mind. We make no compromises for the sake of your delicious experience.
Allergy management is more than just removing allergens. If removing them diminishes the taste or satisfaction of the dish, the special experience of dining out is ruined. At our Keihan Ishiyama izakaya, we devise ways to maximize the natural flavors of our ingredients so that deliciousness is not compromised even when allergens are removed. In particular, our fresh seafood direct from the fishing port is perfectly suited for allergy-friendly meals, as its deliciousness shines even with simple cooking methods.
For company parties, gatherings with friends, or family get-togethers, we cater to large groups for banquets, celebrations, and parties in Ishiyama. We take special care to ensure that even if someone in the group has allergies, everyone can spend their time together enjoyably and safely.
Even when you visit us for a date night in Ishiyama, we are dedicated to providing meticulous service, including allergy accommodations, so that you both can enjoy your special time to the fullest.
No matter how thoroughly we manage ingredients or refine our cooking methods, we cannot provide safe service if the staff who ultimately interact with customers lack knowledge and awareness about allergies. At our Keihan Ishiyama izakaya, we focus on educating all our staff and raising their awareness so that customers can enjoy their meals with true peace of mind.
Customers with allergies often feel anxious or hesitant when dining out. We strive to create an atmosphere where customers feel comfortable asking questions and communicating their needs. By listening to our customers, empathizing with them, and providing polite explanations based on our professional knowledge, we hope to build a relationship of trust where they feel, I'm safe at this restaurant.
We want to turn a dining opportunity that you might have given up on because of allergies into a wonderful memory at our Keihan Ishiyama izakaya. To that end, each and every staff member acts with professionalism and does their utmost for the safety and satisfaction of our customers.
To ensure you can safely enjoy a delicious meal at our Keihan Ishiyama izakaya, there are a few things we kindly ask for your cooperation on. Following these steps before your visit will enable us to provide smoother and safer allergy support. Your understanding and cooperation are essential for us to provide safe service.
The most important step is to inform us of any allergies when you make your reservation. This allows us to make preparations in advance and be fully ready to welcome you.
Even if you have provided allergy information when booking, our staff will ask for a final confirmation upon your arrival. This is an important process to ensure the information was communicated correctly and to check if there have been any changes in your condition.
If you have any concerns during your meal, please do not hesitate to speak to a staff member. We will politely answer any questions, such as What ingredients are in this dish? or I'm a little worried, could you double-check for me? We want you to be able to relax and enjoy your meal completely.
Our Keihan Ishiyama izakaya welcomes you with delicious cuisine made from fresh, port-direct seafood and carefully selected ingredients, all served with warm hospitality. We also work hard every day to ensure that our customers with food allergies can enjoy that same wonderful dining experience with complete peace of mind.
The allergy support measures at our Keihan Ishiyama izakaya are extensive, from ingredient selection and traceability to meticulous consultations and kitchen coordination, proposing alternative menus that are delicious even after removing allergens, and thorough education for every staff member. Whether for banquets in Ishiyama, parties, date nights, or large group gatherings, we will continue to improve our services so that all our customers will think, I'm glad I came, and I want to come back.
For those who have given up on dining out because of allergies, please rest assured. We prioritize the dietary safety and satisfaction of each and every customer and will prepare your meal with the utmost care. If you have any questions or requests, please feel free to contact us. We sincerely look forward to the day when everyone can gather around a table with a smile at our Keihan Ishiyama izakaya.

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。
