NAGANO's manga series, "Chiikawa," exploded onto the scene in 2020 and quickly became a global sensation. Its unique style captivated audiences even further after its TV anime adaptation, making it a beloved phenomenon.
Now, this adorable franchise is teaming up with Kao's popular shampoo brand, "Merit," for a limited-edition shampoo and conditioner set! Featuring super cute character bottle designs, these sets are slated for a nationwide limited release across Japan starting August 2, 2025!

The collaboration's theme? "Happy Hair Washing with Chiikawa for a Refreshing Day!" The bottles feature an array of beloved characters like Chiikawa, Hachiware, Usagi, and Momonga, bringing a dose of pure cuteness to your shower. And get this: the outer box can be cut out and assembled into mini paper character toys! So even after you've used up the product, the fun keeps going – talk about thoughtful design!
This release includes both standard adult-sized bottles and mini-sized bottles for kids, each sporting different charming illustrations.
▼ Merit Shampoo & Conditioner Duo Set (Adult)
This set uses a gentle, non-irritating foam that cleans effectively. It's packed with dipotassium glycyrrhizate, a plant-derived anti-inflammatory ingredient, plus moisturizing components and five botanical extracts (eucalyptus, chamomile, white birch, lotus, and hinoki cypress). These work together to maintain a healthy scalp and hair, reducing dandruff and itchiness. The shampoo is silicone-free and boasts a fresh, natural floral scent that's simply delightful.

▼ Merit Shampoo & Conditioner Duo Set (Kids)
Specially formulated for children, this set gently cleanses delicate scalps and hair. The shampoo contains plant-derived ingredients (eucalyptus leaf extract, chamomile flower extract, glycerin), while the conditioner features moisturizing components (botanical extracts + lactic acid). The shampoo is silicone-free and has a natural floral scent, transforming bath time into a truly soothing experience.

These limited-edition duo sets are scheduled to hit shelves across Japan on August 2, 2025. They'll only be sold as sets, so no single bottle purchases! And don't forget, the outer box transforms into adorable paper models for continued fun.
With their irresistible designs and thoughtful formulations, these sets are perfect for both adults and kids to collect and use. Keep an eye out – perhaps some Japanese specialty stores in Taiwan might even import them!
