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 all who wish to eat truly delicious food and have a memorable dining experience in Yasu City, Shiga Prefecture. We aspire to bring you precious moments that color your daily dining table, accompanied by seasonal delicacies. In particular, Yasu Robatayaki is a cooking method that brings out the maximum flavor of the ingredients themselves, offering the joy of tasting with all five senses. Surrounded by fire and enveloped in a fragrant aroma, the seasonal ingredients grilled right before your eyes are truly a feast.
In this column, we will delve into how Yasu Robatayaki enriches your dining experience and explore the appeal of our changing menu with the shifting seasons. What brilliance do fresh seafood and mountain blessings reveal over the robata flames? Please read to the end for tips on your next dining out experience.
I want to eat delicious fish today, I want to savor plenty of seasonal vegetables. Even if you think so, when it comes to finding a restaurant, do you ever get lost wondering where truly fresh ingredients are offered, and how their charms are brought out by the cooking method? Especially, seasonal ingredients have limited harvest periods, and judging their freshness and quality is not easy.
Furthermore, there might be organizers looking for a Yasu banquet course for colleagues, or people seeking a Yasu private izakaya for a special gathering with friends, and even those looking for a Yasu smoking-friendly izakaya to enjoy a meal while slowly smoking. It can be surprisingly difficult to find truly satisfying cuisine while meeting various needs. We strive daily to solve these concerns and provide the best dining experience.
We are committed to fresh fish delivered directly from the fishing port, procuring freshly landed seafood every morning from our partner ports on the same day. Our sole desire is to bring you freshness that makes you feel the vibrancy of the fishing port, even while in Yasu. Especially during the peak season, rich, fatty fish and firm shellfish are abundantly stocked, becoming the stars of our robatayaki.
By eliminating intermediaries, we minimize the deterioration of freshness during distribution, allowing us to deliver our fresh fish to you in the best possible condition. While the types of fish caught vary by season, all are carefully selected and perfect for robatayaki.
The greatest charm of robatayaki lies in its simple cooking method that brings out the inherent taste of the ingredients. Our skilled chefs grill fish and vegetables with exquisite heat control, resulting in a crispy exterior and a tender, juicy interior. Especially by slow-grilling over wood or charcoal, a unique aroma is imparted to the ingredients, completing a flavorful dish that cannot be experienced at home.
We sincerely face each ingredient, always striving to maximize its individuality. For instance, seasonal vegetables highlight their sweetness, and fish concentrates its natural umami. With this craftsmanship and the power of fire combined, Yasu Robatayaki transcends mere cooking to become an art form.
Japan's four seasons give ingredients rich expressions. In spring, sea bream and bamboo shoots; in summer, rock oysters and sweetfish; in autumn, returning bonito and matsutake mushrooms; in winter, crab and yellowtail – a wide variety of ingredients reach their peak seasonality. At our restaurant, we vividly reflect the beautiful transition of Japan's four seasons in our Yasu Robatayaki menu.
Our seasonal recommendation menu is truly a special, once-in-a-lifetime encounter that can only be savored during that specific period. Every visit brings a new discovery, and our robatayaki is filled with charms that make you want to return again and again. Please enjoy the new faces of our robatayaki with the changing seasons.
For large gatherings or special occasions, we recommend our Yasu banquet courses, packed with seasonal delights. We spare no effort in using the freshest fish directly from the fishing port and seasonal vegetables, offering a fulfilling course menu centered around robatayaki, from appetizers to the final dish.
For example, in winter, we offer a menu that warms both mind and body, featuring robust winter yellowtail robatayaki as the main dish, along with seasonal vegetable tempura and a closing zosui (rice porridge). In spring, you can enjoy a light and vibrant course incorporating sea bream rice and seasonal wild greens. The Yasu banquet courses are carefully selected and well-balanced to ensure everyone can enjoy seasonal flavors without hesitation. Event organizers can rest assured.
As a Yasu izakaya for organizers, we implement various ideas to lighten the burden on event planners. We offer multiple courses to suit your budget, number of guests, and desired menu content, providing meticulous support for your needs.
If there are allergies or disliked ingredients, please consult us in advance, and we will accommodate as much as possible. We also offer a comprehensive all-you-can-drink plan, ensuring you can enjoy alcoholic beverages to your heart's content. Our Yasu banquet courses can be utilized for a wide range of occasions, from company welcome and farewell parties to gatherings with friends and family celebrations.
We aim not just to provide delicious food, but to offer a special, memorable time for our customers. The fragrant smoke of robatayaki, the lively voices of our chefs, and above all, the exquisite taste woven by seasonal ingredients, will surely liven up your conversations and bring smiles to your faces. We hope you can create unforgettable memories with your loved ones through our Yasu banquet courses.
For customers who wish to enjoy their meal leisurely in a private space, we offer services as a Yasu private izakaya. This is ideal for company get-togethers, class reunions, or family celebrations when you want to chat without worrying about others. We will propose the optimal private party plan according to your number of guests and budget.
The private space can also be rearranged to suit your event's purpose. It can be used for various occasions, such as dinner after an important meeting or a special party with close friends only. Please enjoy seasonal Yasu Robatayaki to your heart's content in a private setting.
In a private space, you can savor seasonal robatayaki even more thoroughly. In your exclusive space, please sharpen your senses and indulge in the fresh fish directly from the fishing port and seasonal vegetables meticulously grilled by our chefs. Each dish, reaching out naturally as conversation flows, will further enrich your gathering.
Precisely because it's a private space, we can flexibly accommodate your requests regarding the pace of your meal and serving times. We strive to provide meticulous service so that you can enjoy your meal and conversation at your own pace.
As a Yasu private izakaya, we help you orchestrate your important day in the best possible way.

The true pleasure of robatayaki also lies in pairing food with drinks. At our restaurant, we offer a rich selection of carefully chosen drinks, including sake, shochu, wine, and beer, to maximize the flavor of the seasonal ingredients and dishes served with Yasu Robatayaki.
For example, a crisp, dry sake pairs well with the delicate flavors of fresh fish directly from the fishing port. For thick-cut grilled vegetables, aromatic shochu or red wine are excellent companions. We will also suggest recommended drinks to match the changing seasonal dishes, so please feel free to ask.
Our restaurant is equipped as a Yasu smoking-friendly izakaya to ensure that smoking customers can also spend their time comfortably. We take care to ensure that both smokers and non-smokers can enjoy their meals in a pleasant environment.
Savoring delicious food and drinks, and then enjoying a cigarette after the meal. Please spend such blissful moments to your heart's content at our restaurant. Our entire staff is dedicated to providing meticulous service so that you can fully enjoy seasonal robatayaki in a comfortable space.
While being a Yasu smoking-friendly izakaya, we also prioritize providing a comfortable space for all customers. The interior of our restaurant offers various seating types, including counter seats surrounding the robata, spacious table seats where you can relax, and private spaces for private gatherings.
It is our wish that you enjoy delicious food and conversation in a clean space, feeling the warmth of the robata. We strive daily to ensure that everyone, from families with children to solo diners and business users, can spend their time comfortably in any situation.
Before your visit, please check our latest information and seasonal recommendations. There may be special fresh fish directly from the fishing port or rare seasonal vegetables in stock depending on the day's catch. Checking in advance can lead to a more fulfilling dining experience.
Also, if you are considering using a Yasu banquet course or a Yasu private izakaya, we recommend making an early reservation. Especially on weekends and holidays, it is expected to be crowded, so contacting us in advance will ensure a smoother experience.
If you have any requests regarding your preferred ingredients, cooking methods, allergies, or dislikes, please do not hesitate to speak to our staff. We will do our best to provide an optimal dining experience tailored to each customer.

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。

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。
