Starting April 16, 2026, a unique collaboration between viviON Inc. and Kotteri Ramen Naritake with the VTuber Otodama Tamako will commence at 6 locations nationwide. During this collaboration, the limited-edition ramen “Tama-chan’s Favorite Heaping Kotteri Soy Sauce Ramen,” filled with Otodama Tamako’s favorites, will be offered, and if the sales target of 3,000 bowls is achieved, it will be available permanently for six months.

A Must-See for Fans! The Dream “All Toppings” Ramen

This limited-edition ramen is an “all toppings” version filled with the personal favorites of Otodama Tamako, a VTuber affiliated with Aogiri High School. The thick soy sauce ramen is topped with green onion, bean sprouts, boiled egg, wakame seaweed, pork belly chashu, and menma. It is priced at 1,600 yen (tax included), and with each bowl ordered, a random “postcard (5 types)” with a special message is included as a gift.

Fans’ Challenge Toward Permanent Collaboration Menu

This collaboration event will establish the menu permanently for about six months if the target of 3,000 bowls is achieved. The offer is available at branches in Tsudanuma, Motoyawata, Kinshicho, Makuhari, Ikebukuro, and Fukuoka Nishijin, where fans can enjoy this special bowl available only at these locations.

Rich Line of Merchandise and Limited Items

In addition, original merchandise will be sold alongside the collaboration ramen. A wide range of goods, from store-exclusive collaboration T-shirts (tax included 4,400 yen) to practical items and collectibles, will be available. The order period is from April 16 to May 19, with delivery scheduled from late July onward.

The Attraction of Aogiri High School

The VTuber group Aogiri High School operates under the motto “Anything goes if it’s interesting!” The group has more than 1 million subscribers on YouTube and achieved a major debut in 2025, showing no signs of slowing down. On their YouTube channel, members showcase a glimpse of them enjoying what they love most in their ideal forms.

Outlook and Impressions

This collaboration provides an opportunity to experience a new food culture through the unique combination of ramen and VTuber. The collaboration with “Naritake,” beloved by Otodama Tamako, presents a rare opportunity for both ramen and VTuber fans to enjoy together. We hope to surpass 3,000 bowls during the period and create a special memory for the fans.
