[Breathtaking Views] Indulge in Premium Shabu-shabu at “Koubai” in TOKYO Solamachi and [Ginza] GINZA SIX

Koubai is a wagyu shabu-shabu specialty brand operated by the long-established Japanese cuisine group, Umenohana Co., Ltd.
In Tokyo, it has only two locations: GINZA SIX and TOKYO Solamachi.
On October 3, 2025, Koubai’s first overseas location is scheduled to hold its grand opening in Thailand, at Dusit Central Park.

The Akaushi “Kosei Beef” served at Koubai is raised stress-free on the vast pastures of Aso, Kumamoto Prefecture.
A distinctive feature of this beef is that beer lees are added to the feed, promoting healthy digestion through yeast and resulting in exceptionally tender, premium-quality meat.
Akaushi (Japanese Brown cattle) is prized for its low fat content and rich yet mild flavor of the lean meat.
By eliminating intermediaries, Koubai ensures the meat is fresh, safe, and of the highest quality.

Koubai offers not only sirloin and ribeye from Kosei Beef, but also a variety of other cuts such as tongue, misuji (top blade), ichibo (rump cap), zabuton (chuck flap), sankaku-bara (brisket point), and even chateaubriand.
Each cut is skillfully prepared by chefs and served in shabu-shabu and sukiyaki dishes.

The shabu-shabu broth features aromatic kombu (kelp).
Two dipping sauces are provided: Koubai’s special rich sesame sauce and homemade ponzu.

The sesame sauce combines kneaded and ground sesame for a luxuriously thick texture, coating the meat well and enhancing the flavor of the lean beef.
The ponzu is mellowed with amazake (sweet sake) to soften the acidity, while a refreshing yuzu aroma adds a refreshing finish—perfect for enjoying the pure flavor of the meat.

Koubai also offers sukiyaki, where the meat’s sweetness and richness are perfectly balanced.
The beef is carefully grilled on an iron plate, creating a juicy, savory taste that pairs exquisitely with the rich sauce.
This luxurious lineup, allowing guests to enjoy both shabu-shabu and sukiyaki, is a hallmark of Koubai and caters to a wide range of preferences.

Seasonal vegetables delivered from all over Japan add color and flavor to the shabu-shabu experience.
Koubai is committed to using only domestically grown vegetables, sourcing from regions where the produce is at its best during the season.
Guests may even encounter rare vegetables not typically found in supermarkets.

Koubai’s “Soy Milk Amazake” blends authentic amazake, made from rice and rice malt, with soy milk.
The matcha flavor is light and refreshing, while the yuzu flavor is rich and velvety—both are recommended as a dessert alternative after your meal.
The ratio of amazake to soy milk is adjusted for each flavor, creating distinct taste profiles.
As it is non-alcoholic, it is suitable for those who do not drink alcohol.

Located approximately 150 meters above ground on the 31st floor, right next to Tokyo Skytree®, Koubai TOKYO Solamachi is a popular spot for enjoying premium wagyu cuisine with breathtaking views.
During the day, the interior is bright and open, while at night it transforms into a romantic space illuminated by the glittering city lights.
It is ideal for special occasions such as dates and anniversaries, and also caters well to families with young children.

For children, lunch options such as the “Kids’ Shabu-shabu Set” and “Kids’ Sukiyaki Set” are available, allowing them to enjoy wagyu just like the adults.
Gentle-flavored side dishes and desserts are also offered, accommodating children with smaller appetites.
The restaurant provides baby chairs and attentive service, ensuring a comfortable experience for the whole family.

Many regular guests request window-side seating for the views, so booking early is recommended for special occasions.
The interior features a calm, modern Japanese design, with both table seating and semi-private rooms available to suit various needs.
Nearby attractions include Asakusa and Tokyo Skytree, making it ideal for sightseeing, dates, and family gatherings.

Situated in the heart of Ginza, Koubai GINZA SIX offers a serene, sophisticated Japanese setting that feels far removed from the bustle of the city.
With a more formal atmosphere than the Solamachi location, it is a preferred choice for business dinners and refined gatherings.
In addition to shabu-shabu and sukiyaki featuring Kosei Beef, this location offers exclusive courses and à la carte dishes.
Directly connected to Ginza Station via the Tokyo Metro, it is conveniently located for visits after shopping or theater outings.
Highly recommended for those seeking a quiet, high-quality wagyu dining experience.
