2.5D talent group SIXFONIA is collaborating with shabu-shabu restaurant chain Shabu-Shabu Onyasai. The collaboration features a newly drawn visual themed around a “secret date,” as well as a course that comes with a clear card, and limited digital bonuses. It will run from May 20 to July 14, 2026.

The group is a 2.5D talent unit formed by six members who passed an ultra-large-scale audition. They made a stunning debut in August 2022 with their original song “J0KER×JOK3R.” Armed with their musicality and high planning skills, they primarily release original songs, challenge videos using their voices and singing, and cover songs (“utaite”-style videos). In just two years since formation, they have surpassed 1.24 million channel subscribers, rapidly gaining popularity and expanding their influence. Their momentum shows no signs of stopping.
On October 26, 2025, the group held its first 3D live concert, streamed worldwide for free on the official SIXFONIA YouTube channel (the archive is still available). In November, they performed two in-person live shows linked to the 3D concert at Osaka’s Ookini Arena Maishima, followed by two shows in December at Tokyo’s LaLa arena TOKYO-BAY. In spring 2026, they embarked on their 2nd live tour, including a show at K-Arena Yokohama—the largest venue in the group’s history—and drew a total audience of 50,000, concluding in great success.
For this collaboration, a newly drawn visual imagines the concept: “What if the SIXFONIA members themselves came to Shabu-Shabu Onyasai for a secret date?” The outfits incorporate input from the members themselves, resulting in casual looks that highlight their individual personalities. The visual creates a playful, immersive world that makes it feel like you are actually visiting Shabu-Shabu Onyasai with the SIXFONIA members.
Additionally, each member’s recommended shabu-shabu menu item is introduced, making the collaboration feel even closer to your favorite member as you enjoy your meal.

Exclusively for this collaboration, an “All-You-Can-Eat Course with Original Clear Card” will be sold. For an additional 330 yen (tax included) on top of the regular all-you-can-eat course, you can upgrade to a course that includes one random “Original Clear Card” (6 types total) featuring the newly drawn visuals. An “Original Clear Card Drink” will also be available, but it can only be ordered in conjunction with the clear card course.
