Collaboration items between Nagano's ``Chikawa'' and street brand 9090 (Ninety Ninety) are available for order at 9090's online store.

In this collaboration, we will create items using original visuals of Chiikawa, Hachiware, Usagi, and Momonga as “wheat gals.” T-shirts, sweatpants, mascot keychains, and rubber keychains will be sold. Available only at online store. They will be shipped sequentially from late July 2026.
