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
To everyone planning a gathering with loved ones in Yasu, our establishment is more than just a place to eat. As a private izakaya in Yasu, we provide a space and cuisine designed to enhance each customer's special moments.
Whether it's a casual get-together with close friends, a family anniversary, a company welcome or farewell party, a year-end gathering, or a meal with hobby group members, the time spent chatting freely in a private space while savoring delicious food creates priceless memories.
We welcome you with warm hospitality and dishes that feature the best seasonal ingredients, ensuring you have an exceptional time. We invite you to create a memorable banquet right here in Yasu.
While there are many izakayas in Yasu available for private booking, you may feel uncertain, asking questions like, Which one should I choose?, What is the quality of the food?, or Can I really secure a private space?
To meet your expectations and alleviate these concerns, we welcome you with the following three commitments:
These commitments are why we are the best choice for customers seeking a private izakaya in Yasu. We invite you to enjoy an experience that surpasses your expectations at our establishment.
At the core of our cuisine is a dedication to shun, or seasonality. The ingredients nurtured by Japan's four rich seasons deliver unique flavors and nutrients that can only be enjoyed at a specific time of year. As an izakaya in Yasu, we cherish this concept above all to provide the best dining experience to our local community.
In spring, we prepare tempura and dressed dishes featuring wild mountain vegetables known for their distinct bitterness and aroma. Edible wild plants like butterbur sprouts and fatsia sprouts, brimming with life, adorn our tables. The spring seas also bring us fresh, firm, and flavorful seasonal seafood. We serve the best fish of the season, such as cherry sea bream and first-of-the-season bonito, as sashimi or grilled dishes, allowing you to feel the arrival of spring.
During the hot summer, you'll crave light and refreshing dishes to cool down. Our colorful salads made with crisp summer vegetables and chilled dishes with a smooth texture are sure to whet your appetite. We use an abundance of fresh cucumbers, eggplants, and tomatoes grown around Lake Biwa to create visually refreshing plates. You can also enjoy summer seafood delicacies like conger eel (hamo), either blanched or as tempura, for a true taste of the season.
The autumn of appetite is a true feast for the senses. Dishes featuring chestnuts, mushrooms, and new-crop rice—the bounties of the earth—decorate our tables. Indulge in the luxuries of autumn with fragrant matsutake mushroom rice, foil-grilled mushrooms packed with umami, and salt-grilled saury at its fatty peak. Fresh vegetables and fruits from Shiga Prefecture are also prepared in ways that maximize their unique sweetness and flavor.
In the cold winter, a hot pot that warms you from the core is the ultimate treat. We offer a variety of hot pot dishes, including luxurious sukiyaki and shabu-shabu featuring Omi beef from Yasu, Shiga's prized brand of cattle, as well as seafood hot pots brimming with fresh catches from the sea. The harmony of rich broth and seasonal ingredients provides a warmth that makes you forget the harsh cold. Of course, winter delicacies and seasonal fish can also be savored slowly with a glass of sake.
In this way, we offer a diverse menu throughout the year that allows you to experience the changing of the seasons. We promise a luxurious time savoring the seasonal best of Yasu with all five senses in a private space with your loved ones.
For us, located in the fertile land of Yasu, it is our important mission to make the most of local ingredients. In particular, Shiga Prefecture's prized Omi beef and fresh seafood are the two proud pillars of our establishment.
Omi beef, one of Japan's top three wagyu brands, is characterized by its fine-grained texture and the sweet flavor of its melt-in-your-mouth fat. We offer carefully selected Omi beef prepared in various ways. Enjoy the profound umami of Omi beef through dishes like seared sushi, tataki (lightly seared), steak, and seasonal hot pots.
We invite you to savor these exceptionally luxurious dishes for your special banquet.
Although Shiga Prefecture is landlocked, we source fresh seafood directly from the day's catch through trusted routes. We deliver seasonal fish at peak freshness to your table.
We offer our seafood prepared in the optimal way for each type of fish and season, whether it's a beautiful sashimi platter with translucent flesh, charcoal-grilled to bring out its natural flavor, simmered, or made into tempura. Fatty seasonal fish, in particular, pairs wonderfully with sake and is sure to liven up the conversation.
Our pride as an izakaya in Yasu lies in our thorough commitment to this Omi beef and seafood. Experience the luxury of enjoying the rich bounties of both Shiga's land and the sea while in Yasu. Please enjoy this indulgent experience at your leisure in our private space.

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。
安くて美味しくて雰囲気も良かった。欠点は立地が悪いくらいなので、近くまで来たらオススメです!😁
入り口で迷ってたら すぐにお出迎えしてくれて 気持ちが良かったです。 どのメニューも美味しそうなのと お通しきゅうりとお味噌も美味しすぎました!!! なんといってもすずちゃんが最高の接客してくれて丁寧で可愛くて 美味しくビール呑めました。 またいきます。
お店も清潔感がかり、気取らないけど接客は丁寧なところが良かった。もちろん味もボリュームもよし!
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。
