HIKAKIN-Produced "ONICHA & Misokin" Dominate Category Rankings! Unraveling the Phenomenal Bundle Purchases Driven by "Oshi-katsu Consumption"

Research and Innovation, Inc. analyzed the sales performance of HIKAKIN-produced products "ONICHA" and "Misokin," which were launched exclusively at 7-Eleven on April 21, 2026, using purchase data from their app "CODE." Within one week of launch, both products dominated the top spots in the Japanese tea/barley tea category and the cup noodle/rice category. The buyer demographic showed a significant increase in young people, HIKAKIN's main audience, as well as their parents who made proxy purchases. Notably, the bundle purchase rate was high, with 13% of "ONICHA" buyers purchasing "Misokin" at the same time. This figure is significantly higher than the category average bundle purchase rate of 6%. This data analysis reveals that introducing influencer products attracts new customer segments and boosts overall category sales. It can be said that "Oshi-katsu consumption," the fan enthusiasm to "support by buying both," strongly drove the increase in average transaction value.
