Alaska Seafood Fair
Rice Platformer Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Miyuki Kawaharada; hereinafter 'the Company'), which operates the o-nigiri specialty shop 'ONI&Co.' (O-ni and Co.) with the vision of 'O-nigiri as a global standard fast casual,' will launch a total of three menu items luxuriously using 100% natural and sustainable Alaskan seafood. This includes the newly developed 'Alaskan Atka Mackerel Bento' for this project, available from Friday, May 1, 2026, at two stores: 'ONI&Co. Gransta Tokyo' and 'ONI&Co. Tokyo Lab.'.
This initiative is part of the 'Alaska Seafood Fair,' a collaborative project with the Alaska Seafood Marketing Institute, and will be held for a limited time until Sunday, May 24, 2026.
Commitment to Sustainable Ingredients
ONI&Co. has always strived to elevate o-nigiri, a Japanese soul food, to a global standard fast-casual by carefully selecting ingredients with traceable producers, such as 'Harewatari' rice specially cultivated in Aomori Prefecture.
Among these, seafood is one of the most important ingredients for o-nigiri fillings.
ONI&Co.'s popular menu item, 'Black Cod Saikyo-yaki with Maitake Yuzu Okowa,' has long used 100% natural Alaskan black cod.
The quality and flavor unique to Alaskan seafood, protected by strict catch management and sustainability, have earned deep trust from many customers. In this context, we were strongly resonated by Alaska's thorough sustainable fishing philosophy of 'connecting rich oceans to the next generation,' leading us to hold the 'Alaska Seafood Fair' as a special collaborative project.
For this fair, in addition to the new 'Alaskan Atka Mackerel Bento,' we have newly adopted natural Alaskan sockeye salmon for ONI&Co.'s signature product, 'Natural Grilled Sockeye Salmon,' offering a lineup that allows customers to enjoy the blessings of the Alaskan sea more than ever before.
Alaska Seafood Fair Target Menu
At this fair, in addition to our ever-popular classic menu items, we offer the blessings of the Alaskan sea with a lineup of three items, including a newly developed bento for this project.
Alaskan Atka Mackerel Bento with Yuzu Daikon
Alaskan Atka Mackerel Bento with Yuzu Daikon
This is a new bento specially developed for this fair. It features Alaskan Atka mackerel, known for its rich fat content and fluffy texture, paired with refreshing yuzu daikon (radish).
Natural Grilled Sockeye Salmon
Natural Grilled Sockeye Salmon
Natural grilled sockeye salmon o-nigiri has been a popular ONI&Co. signature product, supported by many customers. For this fair, we have newly adopted natural Alaskan sockeye salmon, characterized by its firm flesh and rich flavor, enhancing the original taste with the aroma of perilla leaf.
Alaska Black Cod Saikyo-yaki with Maitake Yuzu Okowa
Alaska Black Cod Saikyo-yaki with Maitake Yuzu Okowa
This is a popular ONI&Co. menu item, combining fatty Alaskan black cod prepared in Saikyo-yaki style with okowa (sticky rice) flavored with maitake mushrooms and yuzu. It's a dish focused on the perfect marriage of ingredients.
Representative's Comment
ONI&Co. has always aimed to earnestly address each and every ingredient in pursuit of its vision: 'O-nigiri as a global standard fast casual.'
I myself had the opportunity to visit Alaska, directly observing the efforts of the fishermen and the strict catch management and resource conservation continuously undertaken by the state and the fishing industry as one. Deeply impressed by their dedication to protecting the ocean's bounty for future generations, Alaskan seafood has become one of the essential ingredients supporting ONI&Co.'s o-nigiri and bento moving forward.
For this fair, in addition to the classic sockeye salmon and black cod, we are newly offering 'Atka Mackerel' in a bento format. From the two stores – Gransta Tokyo, a gateway to Tokyo, and Hatsudai, its birthplace – we hope to convey the blessings of the Alaskan sea and the sustainable values behind them to as many customers as possible through our o-nigiri and bento.
