Carstay supplied four campervans as a mobile headquarters for the organizers of the Rainbow Disco Club 2026 music festival in Izu, Shizuoka Prefecture. The vehicles were used from April 9 to 22 as office, rest area, and accommodation for staff, as well as for equipment management directly on the festival grounds.
Carstay operates a platform business including campervan sharing and overnight parking spots, as well as vehicle manufacturing and renovation. The use of campervans helped solve logistical issues that had existed in previous years.
