Sakazen Shoji Co., Ltd. (Headquarters: Chuo-ku, Tokyo / President and CEO: Takashi Murakami) announces the launch of a collaborative apparel collection between its new original plus-size casual brand 'CHUBBY’S CLUB,' released in 2025, and Domdom Food Service Co., Ltd. (hereinafter 'Domdom Hamburger'). The collection will be released on July 17, 2026.

◆ Background of the Collaboration

Previously, manufacturers holding the Domdom Hamburger license had proposed 'an interesting initiative,' but at the time, Sakazen lacked the right 'vehicle (brand)' to fully express Domdom Hamburger’s unique sense of excitement and lovable world view.

Driven by the strong belief that 'we don’t want to release compromised products,' we once abandoned the idea of bringing this collaboration to life.

The turning point came last year with the launch of 'CHUBBY'S CLUB,' a new brand that injected entirely fresh 'playfulness' and 'HAPPY' into the classic, timeless styles Sakazen has long offered.

We became convinced that this brand—proclaiming 'appetite wide open!' and 'positive wear like nothing else in the world'—was the perfect 'vehicle' we had been searching for to maximize the Domdom Hamburger universe.

We immediately reached out again to the manufacturer, restarting the collaboration project we had once abandoned. By weaving together the 'DNA of happiness' from both brands, we are proudly launching this collaborative collection in July.

◆ Brand Concept

True to its brand concept, offering clothing that everyone—regardless of age or gender—can enjoy

'CHUBBY’S CLUB' is a brand of positive wear born from the concept that 'even larger sizes can be cute and stylish.'

Until now, our company has offered many basic, functional, and easy-to-wear plus-size items suitable for anyone. However, wanting more people to express their own unique individuality, we created this brand aiming to become a 'new icon in plus-size fashion.'

We aim for people of all ages and genders to enjoy fashion. Our collections are themed around 'HAPPY clothing,' featuring playful designs that make you want to take photos instantly.

◆ Product Lineup

A limited collection merging CHUBBY'S CLUB’s signature pop designs with beloved Domdom Hamburger icons (such as Domuzou-kun). We offer one-of-a-kind positive wear designed for the unique styling possibilities of larger body types.

◆ Comment from Shota Fujita, Casual Goods Buyer

We hope you enjoy the 'happiness of eating' and the 'joy of wearing' in Sakazen’s big sizes!

What we at 'CHUBBY'S CLUB' aim to create is 'positive wear like nothing else in the world'—apparel that excites and enriches people’s daily lives. Domdom Hamburger, with its unique fun menus and delicious flavors, is a wonderful presence delivering 'delicious smiles' across Japan.

'The happiness felt by anyone when they bite into something they love and find delicious.'

We hope you experience the excitement of wearing that feeling as fashion through this collaboration. Through this unique crossover of clothing and food, we aim to let everyone fully enjoy both fashion and appetite, spreading waves of happy energy and smiles across Japan through these collaborative products.
