What this is
Now in its 15th iteration, this long-running collaboration between virtual liver agency Nijisanji and all-you-can-eat dessert chain Sweets Paradise transforms 10 restaurant locations across Japan into themed cafés celebrating six featured members — Genzuki Tojiro, Nagao Kei, Kaida Haru, Sasaki Saku, Shiina Yuika, and Makaino Ririmu. Newly commissioned artwork depicts the characters in white-and-red-plaid school uniforms, which will appear across the collaboration menu, merchandise, and bonus items (full details to be announced closer to opening). Event periods vary by location, running from mid-August through mid-September 2026.
Who should go
Nijisanji fans, particularly those who follow the six featured members. The all-you-can-eat format makes it a relaxed sit-down experience rather than a quick pop-up, so it suits groups of friends who want to linger over themed food and collect bonus items.
Good to know
Reservations for Sweets Paradise collaboration cafés are typically made through the official Sweets Paradise website or app — foreign credit cards are generally accepted online, though the site is Japanese-only so a translation tool is helpful. Each visit usually comes with a random bonus item (such as a character card), with the specific distribution method announced on the official site nearer the event. Sweets Paradise operates on a time-limited all-you-can-eat model, so expect a set dining window of around 70–90 minutes per booking. The Fukuoka location is inside Fukuoka PARCO, a central shopping complex a short walk from Tenjin Station on the Fukuoka City Subway.
