Press Release
Combining the gentle feel of natural cotton with IFMC. processing, inspired by hot spring therapy, this garment nourishes both mind and body through both comfort and functionality.
We are pleased to announce the release of our 100% cotton recovery series, a collaboration with mucava, a relaxing wear brand that uses IFMC. processing, starting April 28th, 2026 (Tuesday).
UCHINO has always prioritized the gentle feeling it provides the moment it touches the skin, and has consistently stuck to using 100% cotton as its material.
The softness and comfort unique to natural materials gently support your daily life.
The Recovery Series is a collection of items born from combining UCHINO's signature comfort with a new perspective from IFMC.
IFMC. is
IFMC (Integrated Functional Mineral Crystals) is a nanometer-level, extremely small mineral crystal manufactured by Teikoku Pharmaceutical Co., Ltd., based on its focus on hot spring therapy.
This substance is extracted by combining several types of minerals, immersing them in iron-rich hot spring water for a certain period of time, and then specially processing the resulting eluate.
By bringing it into contact with the body, nitric oxide (NO) diffuses from the blood vessels, and a blood circulation-promoting effect can be expected due to the dilation of the blood vessels.
Research is underway at the University of Tokyo's Institute for Advanced Sports Science and Technology (UTSSI) with the aim of applying this technology to the medical and nursing care fields.

Features of the UCHINO Recovery Series
01 Soft 100% cotton. We focused on making it comfortable to wear.
Its soft, light, and smooth texture gently envelops your body. It's gentle on the skin and recommended for those who are bothered by the scratchy feeling of synthetic fibers.
02 Comfortable without getting stuffy from sweat or moisture
Thanks to the absorbent properties of cotton, it quickly absorbs sweat and moisture. It reduces stickiness and stuffiness, keeping you comfortable all night long.
03 IFMC processed. Promotes blood circulation just by wearing it.
The UCHINO Recovery series uses cotton material processed with "IFMC." (Ifmic), which was created based on the concept of "improving your physical condition just by wearing it," and draws inspiration from hot spring therapy.
