Asahi Soft Drinks opened the campaign site for a collaboration between its Dodecamin drink and the VTuber group VSPO! (ぶいすぽっ!) on October 27, 2026. Customers who buy Dodecamin in 600 ml BIG PET bottles will be able to apply for original items, but the page states that the date applications open has not been decided.
At a glance
- Announced: campaign site opened October 27, 2026, around 18:00 JST, via Asahi Soft Drinks’ official X account
- Product: Dodecamin BIG PET 600 ml bottles with a campaign seal
- Six VSPO! members appear: Kurumi Noa, Tachibana Hinano, Nekota Tsuna, Shiranami Ramune, Sentoh Yuhi and Choya Hanabi
- Application period: not yet set; the company is checking the system’s security following a PHP vulnerability
- Prizes: acrylic keychains (instant result) and backdrop acrylic stands (drawn later)
- Applications are online only and require adding Asahi Soft Drinks’ LINE official account as a friend
What was announced
The campaign site went live on the evening of October 27, and the hashtags “#ドデカミン × #ぶいすぽ” and “#ぶいすぽ_ドデカ民計画発動中” were used in the announcement. A collaboration had already been announced earlier in the week, with details postponed while the company responded to the PHP vulnerability, according to the news site VTuberNews.
The site describes a points system. Each campaign seal on a 600 ml BIG PET bottle gives one point toward both a guaranteed course and a lottery course. In the lottery course, acrylic keychains are drawn at the moment of application and the result is shown immediately. Backdrop acrylic stands are drawn later, and winners are told through LINE. The guaranteed course offers original items, but the page we read does not list them. The page asks customers to keep the seals until applications open.
Bottles without a seal do not qualify. Applications are made online, with no postcard entry, and entrants must be friends with Asahi Soft Drinks’ LINE official account.
Where it is sold
The page lists Seven-Eleven, FamilyMart, Lawson (excluding Natural Lawson), Lawson Store 100, MINISTOP, Daily Yamazaki, Poplar Group, L-Mart and JR Tokai Retailing Plus, and notes that availability varies by store. The customer inquiry line is open from October 23, 2026 to April 9, 2027. That range is for inquiries and not the campaign period, so the campaign end date remains unknown.
What it means for overseas viewers
This is a domestic Japanese convenience-store campaign. Entry needs a seal from a bottle bought in Japan and a LINE account linked to the campaign, so overseas fans are unlikely to be able to enter directly. Fans abroad can follow the official campaign site and the VSPO! accounts for any changes, and for whether goods appear later through other channels, which has not been announced. The embedded video is from VSPO!’s official channel and shows the group’s DAY 1 stream from VSPO! SHOWDOWN 2026 powered by RAGE, a related official video and not part of this campaign.
What we don’t know yet
- The date applications open and close
- The full list of prizes in the guaranteed course
- Whether any content or video featuring the campaign will be released
