Receipt Campaign — Limited Collab Bottles for 5,000 Winners
To enter, participants must upload a receipt showing the purchase of 2 or more IROKA products in a single transaction. A total of 5,000 winners will be selected by lottery to receive a limited collaboration bottle (one design of their choice) featuring a liver’s visual, along with a campaign sticker. Entrants can select their preferred design, and the bottle ships filled with product. In addition, all entrants receive digital wallpapers (5 types total) with handwritten messages from the livers.
The receipt eligibility period runs from July 16 to August 16, with the entry deadline set at August 23 at 23:59. Details are available on the campaign special site.
Web Commercials, Outdoor Ads, and a YouTube Special Live Stream
The media rollout is multi-faceted. On July 16 at 20:00, a special YouTube live stream was held on the “Ibrahim【Nijisanji】” channel, where all 4 featured members announced the campaign details. The archive is still available for viewing.
Two web commercials have been produced: the “Surprise from IROKA” edition launched on July 9, followed by the “Get Your Limited Novelty” edition starting July 16. Outdoor advertising (OOH) will also be displayed at a location in Tokyo from August 3 to 9.
IROKA Offers 6 Fragrance Varieties
The eligible IROKA products span 6 fragrances: Naked Lily, Handsome Leaf, Pure Freesia, Holy Jasmine, Grasse Rose, and Cotton Musk. In addition to fabric softener, clothing fragrance and laundry scent boosters are also eligible for the campaign.
Outlook
VTuber collaborations with household goods brands have been on the rise, but a major manufacturer like Kao launching a large-scale media mix spanning web commercials, outdoor advertising, and a YouTube live stream is particularly noteworthy. This initiative, which drew significant attention from the initial collaboration announcement, is clearly designed to convert the purchasing power of Nijisanji fans into real in-store sales. The generous prize pool of 5,000 winners also signals a strong focus on brand awareness expansion.
