OSAJI, the sensitive skin brand dedicated to designing skincare lifestyles for healthy and beautiful skin, is releasing the Ryo series on a limited-quantity basis starting May 13, 2026.
Instant cool in the sweltering summer.
As Japan's summers grow increasingly harsh each year, the Ryo series for 2026 has been updated with even stronger cooling sensation. The cooling effect has been enhanced to help people stay comfortable during the hot and humid season.
New for this year, camphor — a refreshing ingredient — has been added to all items except the Raw Soap. This makes it easier to cool down comfortably even on sweaty summer days.
The amount of cooling ingredient has been precisely calibrated based on a formulation designed to be gentle even for sensitive skin, pursuing a mild refreshing sensation that is not overpowering. Enjoy the fresh, lemon-zest-like fragrance along with the cooling sensation.

Container & Design
Inspired by the image of finding a moment of coolness amid summer heat, the design expresses a refreshing sensation through a mint green gradient and a smooth, frosted-glass-like texture.
For hair care items, the gradient flows from the top, while for body care items it flows from the center, each evoking the cool sensation spreading from the head or the core of the body.
