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
In Yasu City, Shiga Prefecture, enjoy a vibrant moment surrounded by the flames of robatayaki. The savory aroma of fresh seafood and mountain delicacies, slowly grilled over charcoal, stimulates the senses of all who visit, offering a blissful time away from the everyday. At our Yasu Robatayaki, we hope that everyone can enjoy such a superb dining experience to their heart's content.
However, in recent years, many customers have consulted us with concerns about food allergies. It's a shame to dine out but be unable to truly enjoy it due to allergy worries. Knowing there are people who harbor such anxieties, we decided to address this issue earnestly.
In this column, we will introduce how our Yasu Robatayaki approaches customer allergies and what specific measures we implement. We hope this will be a helpful guide for customers with allergies, or for organizers considering visiting our restaurant with allergic guests, to feel at ease using our establishment.
The first step in allergy management is accurate information from the customer and our diligent inquiry into it. Pre-communication is especially vital when using our Yasu Banquet Course for large groups or when planning a meal in a private space as a Yasu Private Izakaya.
Careful information sharing at this stage forms the most crucial foundation for providing safe dishes to our customers. Please do not hesitate to inform us of even the slightest concern.
One of the true pleasures of Yasu Robatayaki is its array of seasonal dishes, starting with fresh fish delivered directly from the port. To thoroughly address allergies while handling these abundant ingredients, consistent management from sourcing to cooking and serving is essential.
When preparing allergy-friendly dishes, we exercise extreme caution, different from standard cooking. This is our promise to customers, enabling them to truly enjoy Yasu Robatayaki.
Through these thorough management practices and processes, we strive to ensure that customers can safely savor seasonal delicacies, including fish delivered directly from the port, at Yasu Robatayaki.
Our restaurant can also be used as a Yasu Private Izakaya, catering to special occasions for groups. Even when there are customers with allergies, we offer flexible menu changes and alternative suggestions to ensure the satisfaction of the entire group is not compromised.
Our mission is to listen to the requests of each individual customer and find the best possible solution. Please do not hesitate to consult us.
As a Yasu Smoking-Friendly Izakaya, we provide a comfortable space for customers who wish to smoke while dining. While this is not directly related to allergy support, it reflects our commitment to pursuing customer comfort.
Precisely because we are a Yasu Smoking-Friendly Izakaya, we do not forget meticulous attention to detail to ensure all customers can spend their time comfortably. Please feel free to let us know if you have any requests.
Through these steps, by cooperating with our customers, we can build a safer and more enjoyable dining experience.
Our restaurant, Yasu Robatayaki, wishes to be a place where not only delicious food is served, but where each customer feels truly satisfied and can smile. Food allergies can be a source of anxiety in an otherwise enjoyable dining setting, but we are working day and night to alleviate that anxiety and ensure you can dine with peace of mind.
The freshness of fish delivered directly from the port, the distinctive aroma of robatayaki grilled over charcoal, and our heartfelt hospitality. We want all customers, including those with allergies, to experience all of these with confidence. That is our unwavering commitment as Yasu Robatayaki.
As a Yasu Smoking-Friendly Izakaya, and as a restaurant offering Yasu Private Izakaya and Yasu Banquet Course options, we eagerly await your visit with the flexible responsiveness and hospitality cultivated through meeting diverse needs. Please feel free to inform us of any allergy concerns or requests. Our entire staff will do our utmost to provide you with a wonderful and memorable time.

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。
