A Chiikawa brand collaboration is a tie-up in which the Chiikawa IP works with an outside brand on limited products, in-store campaigns or member benefits. Licensing is handled by the rights management company SpiralCute Inc.; in mainland China Alifish has handled operations since October 2024.
Collaborations usually run in waves: a theme and product line-up are announced first, then goods go on sale in brand stores, official online shops or pop-ups. Repeated tie-ups with the same brand form a series, so entries here are grouped by brand, with the waves described in the body.
