Celebrate Two Years of Risdom with a Unique Collaboration Event
An exciting collaboration is taking place as Kappa Sushi marks the second anniversary of the educational app Risdom. This triple collaboration involves the popular 2.5D idol group Ireisu and is designed to enhance both dining and learning experiences. Starting from March 12, 2026, guests can enjoy special offerings at Kappa Sushi all over Japan.
What’s in Store?
The campaign themed "Eat, Learn, and Support! Touring Kappa Sushi with Ireisu this Spring" presents a dynamic fusion of dining and English learning. A special collaboration event within the Risdom app, featuring a limited-time version of the Kappa Sushi theme song arranged by Ireisu, is also live. Players can navigate through a unique game stage that showcases this catchy tune. With vibrant visuals and engaging gameplay, learners will have fun while improving their English skills.
Besides the app activities, Kappa Sushi is also enhancing the dining atmosphere with a specially curated collaboration menu featuring dishes inspired by Ireisu members’ favorite foods. Custom announcements from Ireisu members will echo through the restaurant, adding to the unique ambiance. Plus, original music videos will stream on digital screens, deepening your immersion into Ireisu's world.
A Closer Look at the Special Menu
Guests can indulge in two themed sets:
1.
Adult Set: Crafted around the preferences of the adult members of Ireisu, this set includes ten exquisite sushi pieces and a seasonal Chawanmushi (Japanese steamed egg). The combination is designed for both taste and satisfaction.
2.
Children’s Set: This playful option is influenced by the younger members' favorites and features an adorable dessert, Spring Pancakes, reflecting their individual styles.
In addition to enjoying great food, every order from the collaboration menu comes with exclusive items: an original A5 notebook and stickers, making your experience not just a meal but a memorable event.
Interactive Fun with Risdom
Participants will also have the opportunity to experience something special in the app. Ireisu members, donned in exclusive collaboration outfits, will make appearances in-game. Alice and Ridel, characters from Risdom, have undergone a design transformation for this event and will support players as they dive into the world of sushi and English. If you’re a fan of the characters, you’ll surely appreciate their engagement during the campaign.
Moreover, new illustrations depicting Ireisu members as chibi characters will be featured within the app, contributing to the collaborative theme of the event. Don’t be surprised if familiar faces such as Kaar-kun and Paa-ko also make their app entries to spice up your learning journey.
Music and Moments to Cherish
Kappa Sushi also launched a special music video, created exclusively for this collaboration, featuring the arranged theme song. The animated video is available on Ireisu's official YouTube channel starting March 7, and it’s also playable within the store via touch panels, ensuring that diners can soak in the fun ambiance.
Moreover, be on the lookout for hidden sushi messages within the song's lyrics as you browse through the lively visuals!
