By applying special technology with a track record of supply to the Japan Ground, Maritime, and Air Self-Defense Forces, it achieves both overwhelming durability and super water-repellent performance while being environmentally conscious, maintaining high water repellency even after 20 washes.

Development Background and Social Significance: "Wearable Disaster Preparedness" to Prevent Hypothermia Risk During Evacuation

In 2026, 15 years after the Great East Japan Earthquake, measures against cold and wetness during disasters are once again drawing attention. In a "Survey on Awareness of Winter Disaster Evacuation and Waterproofing Measures" conducted by uchiko LLC in January 2026, 77% of households (524 votes) responded that they "are not prepared for waterproofing (wetness prevention) of clothing and shoes." Evacuation in rain or snow poses a serious blind spot, as wet clothing can lead to body heat loss and increase the risk of hypothermia. This product applies technology from products supplied to the Self-Defense Forces for operations in harsh environments. It is a product certified as "Phase Free," which transforms everyday outerwear and shoes into a "shelter" to protect against wind and rain during emergencies. It was developed as a socially driven product that balances everyday outdoor convenience with life-saving preparedness for disasters. It is effective not only for disaster situations but also as a countermeasure against the increasingly frequent torrential downpours.

1 Professional Specifications with "1.5 Times" Active Ingredient

The active ingredient content is increased by 1.5 times compared to the standard model. By allowing the concentrated treatment liquid to penetrate deep into the fibers, it maintains a state that easily repels prolonged rain and muddy splashes.

2 "Friction Durability" Forged in Harsh Environments

This product addresses the weakness of common water-repellent sprays: "rubbing." Designed for use in demanding environments, such as by Self-Defense Force personnel, its friction durability has been maximized.

3 Prevents "Chills from Sweat" with Breathability

Instead of sealing the surface, it employs an "infiltrative" technology that coats each individual fiber. By ensuring breathability and moisture permeability, it allows moisture inside clothing and tents to escape, keeping the body dry and reducing the risk of hypothermia.

Future Development and Goals The Makuake project, conducted as a preliminary approach, received overwhelming support, with over 37.24 million yen in crowdfunding from 3,490 supporters, achieving the No. 1 position in the water-repellent spray category on the platform. To meet this strong market expectation, we will begin full-scale general sales on July 1, 2026, starting with our official e-commerce site and expanding to major e-commerce platforms such as Rakuten and Amazon. We aim to bring professional technology into everyday life and contribute to reducing the minor daily stresses of our customers. Simultaneously, it will serve as "equipment that can be used as disaster preparedness" to protect you and your family's lives in times of need. We will expand this Phase Free sense of security not only to special orders but also to general consumers and the disaster preparedness, outdoor, and sports sectors.
