© 2026 UOMARU ISHIYAMA
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.

At our Keihan Ishiyama izakaya, we offer a special experience where you can forget the hustle and bustle of the city and indulge in the ocean's bounty to your heart's content. We take pride in our fresh seafood delivered direct from the fishing port and our wide variety of private rooms suited for any occasion. This article is a practical guide for customers searching for seafood in Ishiyama or an izakaya in Otsu to make the most of what we offer and have the best possible time. If you're undecided on your choice of drinking spots in Awazu, we invite you to read on.
When you're thinking, Is there a good restaurant nearby? or I want to spend quality time with someone special, choosing the right place is crucial. Our goal is not just to serve food, but to create a memorable experience for each and every customer. In particular, our incredibly fresh seafood and our private rooms, designed to protect your privacy and maximize comfort, will surely not disappoint.
By reading this article to the end, we believe you will be able to concretely imagine your time with us and feel inspired to visit.
When you search for Ishiyama izakaya, do you ever feel overwhelmed by the sheer number of options, unsure of which to choose? Many customers face common challenges when selecting a restaurant. For example, have you ever experienced the following?
Choosing a restaurant that satisfies all attendees can be a major source of pressure for organizers planning a banquet or after-party in Ishiyama. Likewise, couples looking for a date spot in Ishiyama need a romantic space where they won't be disturbed. For large group banquets in Ishiyama, factors like seating capacity, layout, and the quality of all-you-can-drink plans become crucial decision-making criteria.
These concerns can lead directly to a disappointing dining choice. But please, rest assured. Our restaurant exists to solve these very problems for our customers. In the next section, we will explain specifically how our direct from the fishing port fresh fish and our private rooms meet and exceed your expectations.
The concrete solutions our restaurant offers to meet our customers' diverse needs are built on two pillars: seafood cuisine delivered direct from the fishing port, pursuing the ultimate freshness and flavor, and a variety of private rooms that cater to every occasion. The fusion of these two elements creates an unforgettable and special experience for our guests.
What exactly makes fish truly delicious? We believe that the lifeblood of delicious fish is, first and foremost, freshness. The reason our seafood cuisine receives such high praise for its exceptional taste lies in our procurement method: direct from the fishing port. We partner directly with skilled fishermen to have the morning's catch delivered to our restaurant in peak condition.
By minimizing the distribution channels, the fish arrives at your table in an incredibly short time after being caught. This allows you to savor the natural sweetness, plump texture, and rich ocean aroma of lively fish—a quality often lost in standard distribution. In addition to seasonal fish, we sometimes receive rare local catches, offering a new culinary discovery with every visit. For customers seeking the best seafood in Ishiyama, this will be an unparalleled delight.
Furthermore, our other signature dish, the Straw-Grilled Bonito (Katsuo no Warayaki), is a masterpiece that truly benefits from this commitment to freshness. A local specialty of Kochi Prefecture, straw-grilling is a cooking method that maximizes the flavor of fresh bonito. By searing the surface instantly over a high-temperature straw flame, the outside becomes fragrant and crisp while the inside remains rare, like tataki. The unique aroma of the straw enhances the bonito's umami, creating a harmony of scent and taste that spreads through your mouth from the first bite—an experience you won't find elsewhere. Many customers seeking this artisanal delicacy make their way to our izakaya in Otsu and Keihan Ishiyama.
To meet our customers' various needs, we offer a diverse range of private rooms, each with its own character. These are special spaces where you can enjoy your meal and conversation to your heart's content. Here is a guide to help you choose the perfect room for your occasion.
Special Dates and Anniversaries (Ishiyama Date Spot)
For those who want an undisturbed, quiet, and calm atmosphere for their important time together, our moody, fully private rooms with dimmed lighting are ideal. The perfectly sized space allows you to talk leisurely without worrying about neighboring tables, creating a romantic setting where you can grow closer. We can also accommodate surprise celebrations if you let us know in advance.
Small Gatherings and Chats with Friends
For casual get-togethers with close friends, our semi-private rooms with horigotatsu (sunken kotatsu) seating are highly recommended. You can stretch out your legs and relax, enjoying great food and drinks in good company. While you can still feel the lively atmosphere of the restaurant, your group has its own defined space, encouraging natural conversation. It's also perfect for those looking for a casual drinking spot in Awazu.
Business Use and Entertaining Clients
For important client dinners or business meetings, we offer formal, fully private rooms. With soundproofing for confidential discussions and spacious table seating, you can conduct your business in a calm environment. Our high-quality cuisine and service will help support the building of smooth business relationships.
Family Meals (Safe for Small Children)
Our spacious private table rooms are popular with customers who have children, as they allow you to dine without worrying about disturbing others. Since there's less concern about bothering other guests even if your children get a little loud or move around, the whole family can enjoy a relaxing and fun time. We also have high chairs available for young children, so please feel free to ask.
Banquets, After-Parties, Welcome/Farewell Parties (Ishiyama Banquet Izakaya, Ishiyama After-Party, Ishiyama Large Group Banquet)
For large gatherings like company banquets, department after-parties, or club welcome/farewell parties, we offer spacious private rooms that can be booked for exclusive use. We can connect tables to create a unified space or utilize equipment like projectors for events. For large group banquets in Ishiyama, we provide a comfortable space for everyone, a variety of course menus to fit your budget, and extensive all-you-can-drink plans to reduce the organizer's burden and ensure a successful event.
Exquisite dishes made with seafood direct from the fishing port and private rooms tailored to our customers' occasions. When these two elements come together, they create an ultimate experience that goes beyond a simple meal. For example, on a special anniversary, you can slowly savor a luxurious course meal featuring an abundance of fresh seafood in a beautiful private room. At a lively banquet, you can gather around delicious food and drinks and have a great time with your friends without worrying about your surroundings.

Now that you know what makes our restaurant special, we hope you're feeling inspired to visit. Here are the concrete steps to help you make the most of your time with us. By following these steps, you are sure to have a highly satisfying izakaya experience in Ishiyama.
Start by Gathering Information: Check the Menu and Private Rooms
Begin by visiting our official website or social media. There you can find the latest information on our dishes, including seasonal fresh fish, limited-time menus, our signature Straw-Grilled Bonito, and special daily recommendations that are direct from the fishing port. We also have photos that show the atmosphere and size of our various private rooms, helping you to visualize the perfect setting for your occasion. Detailed information on our course menus with all-you-can-drink options and plans ideal for banquets in Ishiyama is also available.
Clarify the Occasion: Who, and for What Purpose?
Think specifically about the purpose of your visit. If you're looking for a 'date spot in Ishiyama,' a quiet, fully private room and a slightly luxurious course menu would be ideal. For a 'banquet' or 'after-party in Ishiyama,' a larger private room that can accommodate a big group and a course with an all-you-can-drink option for everyone to enjoy would be better. We also have optimal rooms and menus for family dinners or for casual use as a drinking spot in Awazu. Clarifying your purpose will make the reservation process smoother.
Early Reservations Are Key: Private Rooms Are in High Demand
Our private rooms, in particular, tend to book up quickly, especially on weekends, holidays, and event days. If you are planning for a special day or a large group, we recommend making a reservation as early as possible. Reservations can be made by phone or through our online booking system. When you book, providing details such as your preferred room type (horigotatsu, table, fully private, etc.), number of guests, any allergies or dietary restrictions, and special requests (like an anniversary surprise) will help us serve you more smoothly. We get especially busy during the seasons for large banquets and welcome/farewell parties in Ishiyama, so booking early is crucial.
Making the Most of Your Visit: Don't Hesitate to Ask Our Staff
Once you arrive, our staff is here to support your best possible experience. If you're unsure what to order, feel free to ask for recommendations on the day's fresh fish 'direct from the fishing port,' dishes made with seasonal ingredients, or local sake that pairs well with the food. We will make the best suggestions based on your preferences. Also, please don't hesitate to let us know if you have any requests, such as help with a surprise or considerations for guests with small children. We always do our best to bring your 'wants' to life.
By following these steps, please come and create an unforgettable memory at our izakaya in Ishiyama. As a Keihan Ishiyama izakaya, we sincerely look forward to your visit.

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。
