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
For those thinking, I want to eat something delicious tonight, or I want to spend some quality time talking with friends, if you're looking for robatayaki in Yasu, please come to our restaurant. We are dedicated to our ingredients daily to deliver the best dining experience that satisfies both body and soul. The seasonal delicacies grilled dynamically before your eyes, the fragrant aroma of charcoal, and the exquisite dishes woven by our chefs' expert skills will surely create a memorable moment for you.
Robatayaki is a traditional Japanese food culture and a simple yet profound cooking method that brings out the best in ingredients. We are proud to bring this wonderful food culture to everyone in Yasu. The moment our customers take a bite and smile, saying delicious, is our greatest joy. With gratitude for each ingredient and sincerity towards our customers, we light the fire today and await your visit.
A major pillar of our Yasu robatayaki is, without a doubt, our fresh fish direct from the fishing port. We have built long-standing relationships with trusted fishermen and brokers, allowing us to source vibrant seafood directly, just landed that morning. This minimizes the time loss of going through a market, enabling us to deliver fish of outstanding freshness to your table.
Seafood arriving from the port is immediately transferred to our in-house fish tank. The fish swimming lively in the tank are a testament to their living freshness. Upon receiving your order, our skilled chefs expertly prepare the fish before grilling it on the robata. This entire process is our unwavering commitment to maximizing the fish's natural umami. The far-infrared effect of the charcoal fire cooks the fish slowly, resulting in crispy, fragrant skin and a plump, juicy interior.
The taste and characteristics of seafood vary greatly with the seasons. Spring brings cherry sea bream and Japanese halfbeak; summer offers rock oysters and abalone; autumn features returning bonito and saury; and winter showcases yellowtail and crab. These seasonal bounties of the sea take center stage in our robatayaki. You can enjoy these seasonal delicacies as sashimi to savor their pure flavor, or as charcoal-grilled robatayaki to relish their fragrant aroma. We hope you can feel the rich seasons of Japan through our Yasu robatayaki.
Our Yasu robatayaki is not only about the finest, handpicked ingredients but also about our extraordinary commitment to the cooking method. In particular, the magic of charcoal using Binchotan is the secret to bringing out the maximum umami of the ingredients. Binchotan charcoal has a stronger heat and superior far-infrared effect compared to regular charcoal, allowing it to quickly sear the surface of the food while slowly heating the interior, locking in the delicious flavors.
The real thrill of robatayaki is the immersive experience of watching a chef grill ingredients right before your eyes. The degree of cooking, the rising aroma of the smoke, the crackling sound, and the changing colors of the food—our chefs use all five senses to determine the perfect moment to serve. They respect the individual characteristics of each ingredient, such as the thickness of the fish, its fat content, and the moisture in vegetables, grilling each item carefully until it reaches its most delicious state. The unique smoky fragrance born from charcoal is a charm exclusive to robatayaki that cannot be replicated by other cooking methods.
Robatayaki is a simple cooking method that enhances the natural flavor of the ingredients without unnecessary additions. However, this simplicity is packed with the profound knowledge and experience of our chefs. We do more than just grill. We offer robatayaki with meticulous attention to detail, from preparing the ingredients to the amount of salt and the timing of the grilling. For fresh fish, for example, we pursue the optimal grilling method for each type, such as using high heat to make the skin crispy while keeping the flesh plump and moist. Our Yasu robatayaki is a true masterpiece, filled with respect for the ingredients and the passion of our chefs.
In addition to enjoying our delicious Yasu robatayaki, we strive to be flexible to accommodate various occasions. From family meals and gatherings with close friends to company farewell parties, year-end parties, and even entertaining important clients, we provide a space and service tailored to your needs.
