[Royal Group] Tenya's New Brand 'Onidon' and 100% Handmade Burger 'JB's TOKYO' to Grand Open Two Stores Simultaneously at Ecute Edition Ochanomizu on July 7th

Royal Contract Service Co., Ltd. (hereinafter 'Royal Contract Service'), which handles the contract business for the Royal Group, as part of its growth strategy based on the group's 'Management Vision 2035', is collaborating with Blues & Brothers Co., Ltd. (hereinafter 'B&B') to grand open two stores simultaneously on Tuesday, July 7, 2026, within 'Ecute Edition Ochanomizu' at JR Ochanomizu Station: 'Onidon', a new onigiri-ten-don specialty store under the Tenya brand, and 'JB's TOKYO', a craft burger specialty store.

Growth Strategy of the Royal Group

Under its Management Vision 2035 of 'Bringing smiles to communities and society through food and hospitality', the Royal Group is creating new value through diverse touchpoints for sustainable growth. In its contract business, the group's mission is to 'improve location development capabilities as a growth engine' and 'enhance业态 development capabilities as a development engine', promoting expansion into growth areas such as airport terminals, highway service areas, sports and convention facilities, and commercial facilities. This project is a challenge into a new market area for the Royal Group: 'developing fast-casual brands that can be deployed in multiple locations in small spaces (around 15 tsubo)'. By bringing in B&B representative Bruce Sato as a producer, the group aims to create synergy by combining its management resources and know-how with B&B's excellent creativity and业态 development capabilities. Under a strong partnership, both companies will work as one to create new value and improve customer satisfaction, and to promote the powerful joint development of both brands.

Tenya's New Brand: Onigiri Ten-don Specialty Store 'Onidon'

'Tenya' is a restaurant that utilizes tempura, a Japanese cooking method, allowing customers to enjoy the deliciousness of ingredients and a variety of seasonal flavors. Meanwhile, the new brand 'Onidon' was developed by maximizing the advantages of tempura and evolving it into a 'tenmusu style', making it accessible to a wider range of customers at various times and for different purposes than Tenya.

● Live Experience of Freshly Fried and Freshly Made

The roots of 'Onidon' lie in the staff meals at Tenya stores. Utilizing the 'system for deliciously and efficiently frying tempura' cultivated over many years at Tenya, it offers a new form of tenmusu that is 'freshly fried and freshly made' quickly, along with the live experience of tempura being fried right in front of customers.

● Satisfying 'One Soup, One Rice'

By combining tenmusu, which offers 'ultimate portability' and can be easily eaten with one hand, with a hearty miso soup packed with ingredients, it delivers a 'satisfying one soup, one rice' experience that is both quick and filling for the stomach and soul.

● Diverse Usage Scenarios and Unique Positioning

Catering to a wide range of needs at various times, from a casual lunch for a solo female diner, to a quick meal for businesspeople and students on the go, or for tourists during a transfer, as well as takeout to be enjoyed anywhere. It is a uniquely positioned fast-casual specialty store that balances high-quality 'dine-in' with the convenience of everyday 'takeout', aiming for multi-location expansion from small spaces.

100% Handmade Craft Burger Specialty Store 'JB's TOKYO'

'JB's TOKYO' is a craft burger specialty store with the unique concept of '100% handmade' for a fast-food hamburger format. Since its founding in 2021, it has gained attention, mainly on social media, and its Yoyogi main store was selected for the 'Tabelog Burger Hyakumeiten (Top 100)' in 2024 and 2026. Customers can enjoy the handmade taste and peace of mind that embodies founder Bruce Sato's belief that 'hamburgers should be as casual a meal as onigiri'.

'JB's TOKYO' currently operates 6 stores in Japan under Royal Contract Service and B&B. With the opening of the 7th store at 'Ecute Edition Ochanomizu' and plans for two more new stores within the year (totaling 9 stores), it is a craft burger brand steadily expanding and growing. For this opening at 'Ecute Edition Ochanomizu' as well, the 'location development capabilities and store operation know-how' of Royal Contract Service and the 'brand production capabilities' of B&B will be fused, maximizing each other's strengths to further grow the brand into one loved by many customers.
