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.

This column will detail how our restaurant can meet and exceed your expectations, providing an unparalleled experience for special occasions like client entertainment and anniversaries. It is filled with valuable information for anyone seeking a special venue in Yasu.
Choosing a restaurant for a special day can be a significant source of pressure for organizers. The quality of the food, the ambiance of the establishment, the level of service, and the budget – it's no exaggeration to say that all these factors determine the success of the day. Perhaps you've experienced some of the following concerns:
All these questions and anxieties can be resolved through our hospitality, centered on Yasu Seafood. We spare no effort to understand and fulfill each customer's important wishes. In the following sections, we will present specific solutions and highlight our restaurant's unique charm.
The primary reason our restaurant is chosen for special occasion dining is our unwavering commitment to the freshness and quality of our Yasu Seafood. Handpicked marine delicacies, delivered daily directly from fishing ports across the country, promise an exceptional taste experience found nowhere else.
For example, we offer seasonal Yasu Seafood such as cherry snapper and early bonito in spring, rock oysters and pike conger in summer, skipjack tuna and Pacific saury in autumn, and fatty winter yellowtail and crab in winter. You can enjoy the finest marine bounty of the season, tailored to your important day.
The term fresh fish direct from the fishing port is genuinely upheld; every dish presented before you is a gift from the sea. With just one bite, you'll surely be amazed by its freshness and exquisite flavor.
Another defining feature of our restaurant is Yasu Robatayaki. Gathered around the hearth, watching our chefs meticulously grill fresh seafood and seasonal vegetables right before your eyes is an entertainment in itself. The savory aroma, the sizzling sounds of ingredients, and the dancing flames further elevate the dining experience on your special day.
The true delight of robatayaki lies in how the far-infrared effect seals in the ingredients' umami, cooking them to be plump and juicy. Especially when enjoying fresh Yasu Seafood as robatayaki, you'll experience a different kind of fragrant depth and rich flavor compared to sashimi. The skin becomes delightfully crispy and aromatic, while the flesh remains tender and moist.
Yasu Robatayaki is perfect for sparking conversation at a business dinner or creating special memories for an anniversary. We offer an experience where you can share the joy of food, fully engaging all five senses—sight, smell, taste, hearing, and touch.
Beyond the deliciousness of the cuisine, the dining space, service, and beverage options are also crucial for ensuring complete customer satisfaction. At our restaurant, we provide hospitality with meticulous attention to detail, creating an ideal setting for Yasu Banquets.
For client entertainment and anniversaries, a private space where guests can focus on conversation without distractions is essential. We offer various types of private rooms to suit your guest count and purpose.
For organizers planning a Yasu Banquet, we can also arrange a preview of the venue. By seeing the space in advance, you can better visualize the actual event. We will do our utmost to ensure that you, our guests, are the stars of any occasion.
To further enhance the deliciousness of our fresh Yasu Seafood, we offer a rich selection of carefully chosen sake. Our thoughtfully curated lineup, designed for perfect food pairings, will satisfy all customers, from sake beginners to connoisseurs.
Sake varies greatly in aroma and flavor depending on its type, allowing for enjoyable pairings with each dish. For instance, a light and dry sake enhances delicate sashimi without overpowering it, while a rich junmai sake pairs exceptionally well with robust simmered dishes or grilled seafood from the robatayaki.
Delve into the profound world of Yasu Sake while savoring our proud Yasu Seafood dishes to your heart's content. Your guests who appreciate fine drinks will surely be delighted.
While smoking regulations have become stricter in recent years, as a Yasu smoking-friendly izakaya, we strive to ensure both smoking and non-smoking customers can enjoy their time comfortably.
By providing designated smoking areas, we create an environment where smoking guests can relax and enjoy their meal and drinks without feeling constrained. We also endeavor to create private rooms and spaces with proper ventilation to prevent smoke leakage, ensuring non-smoking guests also have a pleasant experience.
Important client entertainment or anniversaries often bring together diverse groups. Regardless of smoking preferences, we never forget our meticulous consideration to ensure all guests enjoy an equally comfortable time. Please come with peace of mind.
To ensure a smooth booking and preparation process for your special day, such as client entertainment or an anniversary at our restaurant, we offer the following concrete steps to help you realize your ideal plan.

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。
