Japan's Largest Genghis Khan Chain Opens in Yokohama! 'Taishu Genghis Khan Sakaba Ramuchan Yokohama Store' Opens June 10 (Wed)

Ikka Dining Project Co., Ltd. (Headquarters: Ichikawa City, Chiba Prefecture; President and Representative Director: Taro Takenaga), a consolidated subsidiary of Ikka Holdings Co., Ltd., is pleased to announce the opening of the 17th location of 'Taishu Genghis Khan Sakaba Ramuchan (hereinafter, Ramuchan)', Japan's largest Genghis Khan specialty chain by number of stores*1, where customers can enjoy carefully selected lamb Genghis Khan and tabletop highball towers. The 'Taishu Genghis Khan Sakaba Ramuchan Yokohama Store' will open at 4:00 PM on Wednesday, June 10, 2026. As an opening celebration, customers who bring the store's OPEN flyer distributed at the storefront will receive a 10% discount on their bill*2.

*1 Regarding 'Japan's largest Genghis Khan chain by number of stores', Ikka Holdings Co., Ltd. conducted its own research (public information, each company's official website, etc.) as of May 2026 and confirmed that the company operates the largest Genghis Khan specialty chain in Japan.

*2 Cannot be combined with other coupons/discounts. Can be combined with app benefit VIP all-you-can-drink. Valid only at the Yokohama store. Valid until the end of July 2026.

■ Background of the Opening

The Yokohama West Exit area is the largest business hub in Kanagawa Prefecture and a key transportation point centered around 'Yokohama Station', one of Japan's leading major terminals. On weekdays, many office workers from the surrounding area gather, and on weekends, the demand for alcohol in the nearby entertainment district increases. It is a mature food and beverage market where both business and leisure demand coexist.

With this dual nature, we believe the Yokohama West Exit is an ideal location that can appeal to both of Ramuchan's main target audiences: 'office workers looking to enjoy a drink after work' and 'a wide range of generations who enjoy dining out with friends and family on weekends'.

Our sister brands 'Sushi to Oden Ninoya' and 'Yataiya Hakata Gekijo' are already operating in the same area, and one of the backgrounds for this opening is the ability to leverage the area understanding and customer trend knowledge cultivated through the operation of these existing stores. Additionally, we believe the Kanagawa West Exit area has relatively few competitors in the Genghis Khan specialty business format, making it a market environment where Ramuchan's uniqueness can be easily demonstrated. Going forward, Ramuchan will continue to enhance its brand value and pursue ongoing store expansion through openings tailored to regional characteristics.

■ Features of Taishu Genghis Khan Sakaba Ramuchan

・Specialty Genghis Khan

The signature menu item is the house-made 'Shio-shime Aged Lamb'. Using a secret aging method, we maximize the flavor and tenderness, offering a Genghis Khan that overturns the common impressions of 'concern about smell', 'strong taste', and 'tough meat'. Only specified brands of lamb are used. We are particular about raw lamb and use lamb that suits our signature salt-curing aging method. As a Genghis Khan specialty store, the appeal also lies in the wide variety of menus and rare cuts that make the most of the lamb.

Examples of Genghis Khan Menu Items
Salt-cured Aged Top Lamb Shoulder Loin: 1 serving 890 yen (tax incl. 979 yen)
Drinkable Genghis Khan: 1 serving 890 yen (tax incl. 979 yen)

【Domestic Onion】1 serving 350 yen (tax incl. 385 yen)

・Highball Tower
