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.

We make no compromises, from selecting ingredients to cooking and every detail of our hospitality, to ensure our guests feel, I'm glad I came, and I want to come back. We are especially confident in the freshness of our ingredients, which are the lifeblood of robatayaki. By the time you finish reading this, you'll surely be tempted to open our doors.
We hope to create the best culinary memories for you here in Yasu as we introduce the charms of our restaurant.
Robatayaki is more than just a cooking method; it's an art form that combines respect for ingredients and culinary skill, nurtured by Japanese food culture. Watching our skilled chefs use large wooden paddles to grill ingredients over an open flame is a show in itself. You can see, hear, smell, and taste the entire process—the crackling of the charcoal, the fragrant aroma, and the way the natural flavors of the ingredients are concentrated. While cherishing this traditional robatayaki style, we also incorporate modern touches to meet our customers' needs. In particular, we focus on maximizing the quality of our fresh seafood delivered directly from the fishing port by grilling it over the robata.
To help you fully savor Yasu Robatayaki, our head chef has meticulously designed a course menu that is one of our greatest prides. We select the most delicious seasonal ingredients, with robatayaki as the centerpiece, creating a well-balanced composition that includes appetizers and closing dishes. We highly recommend this course, especially for first-time guests and for organizers planning a Yasu banquet course for a group.
Our head chef's special course generously uses unique ingredients that can only be enjoyed during their peak season. For example, we feature sea bream and spring vegetables in spring, rock oysters and sweetfish in summer, returning bonito and mushrooms in autumn, and crab and yellowtail in winter, sourced directly from fishing ports across the country. This means you can discover new and exciting flavors with every visit. In addition to our signature robatayaki, you can enjoy an assortment of fresh sashimi, creative dishes using seasonal vegetables, and a special clay pot rice to finish.
These courses are not just a sequence of dishes; each plate tells a story and is crafted with care. Please take note of the cooking methods that bring out the natural flavors of the ingredients and the presentation that delights the senses.
Whether it's a company party, a gathering with friends, or a special anniversary, there are many occasions to use our Yasu Banquet Course. For organizers, choosing the right venue is crucial for a successful event. We offer a space and service that resolves organizers' concerns and ensures all attendees have a wonderful time. We are particularly pleased to offer our venue as a private hire izakaya in Yasu for large groups.

This allows you to enjoy conversation and cuisine in your own private space. It's a popular choice for company welcome and farewell parties, year-end parties, and reunions. Please contact us early to discuss private hire options.
With fewer smoking-friendly venues available these days, this has become an important factor for smokers when choosing a restaurant. As a smoking-permitted izakaya in Yasu, we provide a space where you can enjoy both your meal and a cigarette. Our restaurant is designed with consideration for both smokers and non-smokers to ensure everyone has a comfortable experience, so please visit with confidence.
