Our story
Located in the heart of Yasu, 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 private rooms — 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 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
Thirteen counter seats, twelve table seats, eight in the private room and twelve on the terrace: 45 in all. In a room this size, the flames and the crackle of the straw reach every seat.
The finished surface carries the smoke of burning straw. Leave the first slice unseasoned and taste the natural sweetness underneath.
Later in the plate, shift with condiments, rock salt and citrus. Winter brings kanburi yellowtail, whose fat loosens and lightens against salt and citrus.
Every seat, including the twelve on the terrace, allows smoking. Our staff suggest Shiga sake, dry through sweet, to match your sashimi or straw-grilled dish.

Column
Whether you're entertaining an important client, celebrating an anniversary with family and friends, or organizing a department get-together or a casual meeting with close companions, what kind of place do you look for when planning a special gathering in Yasu? Not just a place to eat, but a space where conversation flows and you can spend a memorable evening. Our private izakaya in Yasu is here to make that wish come true.
Located conveniently near Yasu Station, we aspire to welcome each and every guest for their special time in the best way possible. We adorn your banquet with fresh seafood, the rich bounties of Shiga, and warm hospitality. In particular, choosing a private booking allows you to converse without worrying about others, significantly enhancing the value of your gathering.
We're trying to entertain a client, but we can't hear each other over the noise... I wish we could have celebrated our anniversary more leisurely in a private space... For a large party, the burden on the organizer, from choosing a venue to making arrangements, is just too much...
Have you ever faced these troubles when searching for an izakaya in Yasu? Often, a poor choice of venue can ruin the atmosphere of the entire event. The pressure on the organizer is immense, especially for important business dinners, once-a-year anniversaries, or large company banquets.
While the lively atmosphere of a typical Yasu izakaya can be appealing, it's often unsuitable for situations that require quiet conversation. Even with private rooms, the space or ambiance might be limited, or noise from other patrons may leak in. You need to consider many details—the quality of the food, the variety of drinks, allergy accommodations, and smoking policies—and finding a place that satisfies all these criteria is a monumental task.
Our private izakaya in Yasu exists to solve the problems mentioned above and deliver the best possible experience for any occasion. We promise a memorable, special time with meticulous service tailored to your needs and exquisite dishes crafted from carefully selected ingredients.
Our greatest appeal is the option for a private booking, allowing you to spend your time in a completely private space without worrying about other customers. Despite our accessible location near Yasu Station, stepping inside transports you to a special place just for you. We provide an environment where you can forget the outside noise and focus on conversation with your important guests. From small-group entertaining to large-scale banquets in Yasu, the space can be used freely to suit your group size and purpose.
Furthermore, we are equipped as a smoking-friendly izakaya in Yasu to ensure a comfortable time for our smoking guests. We believe that in a private space, both smokers and non-smokers can relax with mutual consideration. For important business entertainment, you can speak candidly without distraction. For anniversary celebrations, you can share your joy to your heart's content. We bring this ideal izakaya experience to life here in Yasu.
The cuisine is one of the most crucial elements determining a banquet's success. We leverage our location in Yasu to offer carefully selected, high-quality, fresh ingredients. Our specialty is the fresh fish delivered daily from the fishing port. We serve the catch of the morning—seasonal seafood—prepared in ways that best bring out its natural flavor, such as sashimi, grilled dishes, or simmered plates. We are confident that even those particular about seafood in Yasu will be satisfied.
Our Yasu Robatayaki grill, with its appetizing aroma, is another signature offering. Seasonal vegetables, seafood, and Shiga's brand-name Omi beef are slowly grilled right before your eyes. By carefully grilling over Binchotan charcoal, the ingredients' natural umami is condensed, resulting in a dish that is fragrant on the outside and juicy on the inside. Omi beef from Yasu is known for its melt-in-your-mouth tenderness and elegant sweetness, making it a perfect delicacy for both business entertainment and special anniversary dinners. For customers searching for an izakaya in Kitano, we offer the finest cuisine right here in Yasu.
Delicious food is incomplete without excellent sake to accompany it. We offer a wide selection of Yasu Japanese sake, carefully chosen from both within and outside Shiga Prefecture. From dry to sweet, Junmai Ginjo to Daiginjo, we will recommend the perfect bottle to match your preferences and your meal. Whether you're a sake connoisseur or a novice, you are sure to make a new discovery.
To meet our customers' needs, we offer a variety of Yasu Banquet Courses. We flexibly accommodate detailed requests regarding budget, dish content, and the number of courses. For business dinners, we serve a well-balanced meal from appetizer to finish, timed perfectly so as not to interrupt conversation. For anniversaries, we assist in making the day special with surprise arrangements or dessert plates. As an organizer-friendly izakaya in Yasu, we strive to reduce the organizer's burden and provide meticulous service so that all attendees can thoroughly enjoy themselves.
I'm worried if you can accommodate a guest with allergies. I want to plan a surprise, but can the restaurant help? I'm concerned about the event running smoothly. We sincerely address these concerns from organizers. We have a meticulous support system in place to ensure your special day is celebrated in the best way possible.
We will ask in advance about food allergies or dislikes and accommodate them as much as possible. We can also prepare special menus so that guests with allergies can dine with peace of mind. For anniversary celebrations, our staff will fully support your requests, such as arranging a cake, allowing you to bring in a bouquet, or timing a surprise. As an organizer-friendly izakaya in Yasu, our experienced staff will conduct detailed preliminary meetings about the event's schedule to assist with smooth operations. As a Yasu izakaya, we promise to stand by our customers and create the best memories together.
First, please feel free to contact us by phone or through the inquiry form on our website. Let us know your desired date, number of participants, budget, and the purpose of your gathering (e.g., business entertainment, anniversary, farewell party). As a Yasu Station pub, we welcome any questions you may have about access.
Based on the information you provide, we will propose the optimal Yasu Banquet Course or a customizable special menu. We will explain in detail the specific dishes and drinks, such as seafood courses centered on fish direct from the port, robatayaki of Yasu Omi beef, and Yasu Japanese sake pairings. At this stage, you can also confirm details like our private booking fee structure, room size, and our facilities as a smoking-friendly izakaya in Yasu. Customers looking for an izakaya in Kitano are also welcome to consult with us.
Once you are satisfied with our proposal, we will discuss finer details such as allergy accommodations, anniversary surprise arrangements, and seating plans. We will resolve any concerns or questions the organizer may have one by one, ensuring everything is perfectly prepared for the day of the event.

カウンターでいただきました。 えびマヨや琵琶マスのお造り、目の前で焼いてくださる旬のお野菜の炉ばた焼が香ばしくて絶品でした! 店員さんがとても親切で、居心地もよい素敵なお店です。 帰り際に毎回いただける手作りふりかけが 家族みんな大好きです!
接客が丁寧で好感持てる。 料理も美しく、提供も丁寧でもちろん全部美味しい。 たまたまかもしれないが、厨房含め女性中心に運営されてるのかな。どうでもいいことかもしれないけど。

木曜日に行きましたがお店はお客さんで賑わっていました。 漁港直結の今朝獲れのお刺身は新鮮で美味しかったしキレイな盛り付けにテンション上がりました。 人気のポテサラはたっぷりのいくらと、とびこのプチプチ感がたまりませんでした。 ホッケも肉厚で美味しかったです。 帰り際にお店の方から小袋に入ったふりかけのお土産をいただきました。 一つ一つメッセージも書かれてて嬉しかったです。 とっても満足な時間を過ごせました。 ぜひまた行きたいと思いました。
