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 in Yasu who wishes to savor truly delicious seafood to their heart's content. When you seek the freshest bounties of the sea, you might wonder where to go for the best experience. It's not just about filling your stomach, but about enjoying a memorable flavor and spending time with loved ones in a comfortable space. As a place that fulfills such desires, our restaurant welcomes customers daily with a deep commitment to our ingredients and warm hospitality.
When you hear Yasu Seafood, what comes to mind? We promise to deliver an experience that exceeds the expectations hidden within those words. Exceptionally fresh seafood, brought to its peak condition by skilled chefs, will adorn your table. In this article, we will detail how we create this ultimate experience, sharing the passion and ingenuity for ingredients that happen behind the scenes.
Your quest for delicious seafood will find its answer at our restaurant. When you want to spend a special evening in Yasu, or simply wish to soothe the fatigue of daily life, please come and knock on our door.
Even within the category of Yasu Seafood, the quality and preparation methods vary widely. The seafood available at the market is diverse, each with its own unique characteristics. What customers are truly looking for is a deep sense of satisfaction that can't be summed up by the word fresh alone. However, the question of which restaurant to choose to find that authentic experience always remains.
Common challenges for many customers include the assurance of freshness and quality, and the expectation of cooking methods that maximize these attributes. Furthermore, dining occasions are diverse, from anniversaries and conversations with loved ones to banquets in Yasu with close friends. Whether a restaurant can provide the optimal cuisine and atmosphere for each scene is also a crucial point when making a choice.
We will now carefully explain our concrete solutions to these questions and challenges, and the reasons why you can choose our restaurant with confidence.
The reason our Yasu Seafood is so special lies, above all, in its freshness and quality. Every morning, we source select fresh fish delivered directly from fishing ports across the country. By minimizing intermediaries, the seafood arrives at our restaurant via the shortest possible route to be served to our customers. This port-direct fresh fish is the core commitment that forms the foundation of our cuisine.
The quality of fresh fish is greatly influenced by the time and handling from catch to table. At our restaurant, seasoned experts with years of experience select the best seafood according to the day's weather and catch conditions. The chosen seafood is then swiftly transported to our restaurant with the utmost care to preserve its freshness. This rigorous management system is the unwavering pillar that supports the deliciousness of our Yasu Seafood.
Japan has four rich seasons, and the sea shows different faces with each one. At our restaurant, we actively incorporate seasonal seafood at its most delicious, offering dishes that maximize the appeal of Yasu Seafood. You can enjoy the unique, luxurious flavors of each season: fatty first-of-the-season bonito in spring, refreshing horse mackerel and squid in summer, returning bonito and saury in autumn, and firm winter yellowtail in winter.
Seasonal seafood possesses a special umami and flavor that can only be enjoyed at that time of year. We respect the inherent deliciousness of each type of seafood, avoiding excessive processing and focusing on cooking methods that bring out the natural taste of the ingredients. With just one bite, you'll feel an excitement as if the bounty of the sea is dancing on your tongue.
To help you enjoy our port-direct fresh seafood at its absolute best, we confidently recommend our Yasu Robatayaki. Robatayaki, where ingredients are slowly grilled over charcoal right before your eyes, is a supreme cooking method that condenses the natural umami of the seafood and adds a fragrant aroma.
The appeal of robatayaki lies in the power of charcoal, which has a far-infrared effect. The surface of the ingredients is grilled to a crisp, fragrant finish, while the inside remains plump and juicy. For fresh seafood in particular, grilling over charcoal removes excess moisture and intensely concentrates the umami. Because it is seasoned simply with just salt, you can fully enjoy the delicate, natural flavor of the seafood.
From the counter seats, you can watch up close as the ingredients are grilled over the charcoal. The crackling sound of the fire, the rising fragrant smoke, and the beautiful colors of the grilling seafood—enjoying this with all five senses is a unique pleasure of robatayaki.
Our robatayaki menu features not only port-direct fresh fish but also seasonal vegetables grown in the rich land of Omi and carefully selected meats. By carefully grilling a diverse range of seasonal ingredients over charcoal, we bring out the best flavor of each. Enjoying a balance of seafood and mountain produce will allow you to experience the gastronomy of Yasu more deeply.
For example, depending on the day's catch, we might recommend salt-grilled fish collar for seasonal fish, charcoal-grilled shiitake mushrooms for fresh vegetables, or salt-grilled Omi chicken. If you're unsure what to order, please feel free to ask our staff.
With delicious Yasu Seafood and robatayaki, you naturally need excellent sake and a space where you can converse to your heart's content. We focus on providing a lineup of sake carefully chosen to pair with our dishes and creating a comfortable environment for both smokers and non-smokers.
Sake is the perfect companion for fresh seafood. Our restaurant offers a wide selection of carefully chosen sake from all over Japan, with a focus on local brews from Shiga Prefecture. We have various types, from dry and crisp to fruity and aromatic, and those with a mellow umami character. You can choose your favorite sake to match your meal.
For example, a sharp, dry junmai sake pairs wonderfully with delicate white fish, while a junmai ginjo with a rich rice umami complements fattier fish, enhancing the flavors of both. If you're unsure which sake to choose, please consult our staff. We will recommend the perfect glass to suit your preferences.
Our restaurant can be used for a wide range of occasions, from small, private dinners to large, lively banquets in Yasu. We are equipped with private rooms that can be chosen according to your needs, allowing you to enjoy conversation and your meal at a leisurely pace without worrying about other guests.
Furthermore, to ensure a comfortable experience for our smoking guests, we have designated smoking areas, operating as a Smoking-Allowed Izakaya in Yasu. We have taken care to separate these spaces from non-smoking areas, creating an environment where everyone can feel at ease. Whether it's a get-together with colleagues, a gathering with friends, or a family meal, we promise our space will enrich any Yasu banquet and make your precious moments even more special.
To everyone seeking truly delicious seafood in Yasu, what our Yasu Seafood restaurant offers is more than just a meal. It is a memorable experience composed of the exquisite taste of port-direct fresh fish, the fragrant aroma of Yasu Robatayaki slowly grilled over charcoal, the perfect marriage with carefully selected Yasu Sake, and a thoughtfully designed space with private rooms ideal for Yasu banquets and consideration as a smoking-allowed izakaya in Yasu.
For the delicious! smile on each and every customer's face, we relentlessly pursue our uncompromising commitment to ingredients and warm hospitality every day. Forget the hustle and bustle of daily life and savor the fresh bounties of the sea to your heart's content. We hope that our restaurant will become a special place for you, whether as a venue for conversation with loved ones or as a treat for yourself. We sincerely look forward to welcoming you.
