Taiyo Kogyo Launches "GREEN FLEX," a Next-Generation Tent Revolutionizing Evacuation Life in Disaster and Conflict Zones
Taiyo Kogyo Corporation, in collaboration with the Japanese Red Cross College of Nursing Disaster Relief Research Institute, has developed "GREEN FLEX," a next-generation tent designed to improve evacuation life in disaster and conflict zones. This tent can be set up by fewer people in a shorter time, provides a comfortable living space even in harsh environments, and will be available for sale to national governments and medical institutions starting May 2026.

Taiyo Kogyo Corporation (Tokyo Headquarters: Setagaya-ku, Tokyo / Osaka Headquarters: Yodogawa-ku, Osaka, Representative Director and President: Yuki Nomura), which handles large membrane structures (tent structures) and civil engineering/logistics materials, has jointly developed "GREEN FLEX," a next-generation tent, with the Japanese Red Cross College of Nursing Disaster Relief Research Institute (hereinafter "JRCC Disaster Relief Research") to solve challenges in humanitarian aid activities. This product achieves a structure that can be set up by less than half the personnel compared to conventional large tents and also provides a comfortable living environment by suppressing temperature changes inside the tent.
Sales will begin in May 2026, targeting national governments, local authorities, fire departments, self-defense forces, medical institutions, and others.

Background of Development
In disaster and conflict areas, tents play a crucial role as command centers, medical bases, and shelters (living spaces). However, large tents have posed challenges such as requiring many people and a long time for setup, and securing indoor environments in harsh conditions. In response to these challenges, development of a next-generation tent began in 2021, at the request of JRCC Disaster Relief Research. Taiyo Kogyo, with its strength in membrane structure technology, and JRCC Disaster Relief Research, possessing the knowledge of the Japanese Red Cross Society gained from humanitarian aid activities in many disaster and conflict zones, jointly proceeded with the development.

In recent years, measures against global warming have also been required in the field of humanitarian aid. Furthermore, in disaster and conflict areas, it is necessary to establish bases quickly with limited personnel. This product was developed with a strong awareness of its utilization in actual aid sites, in terms of its ease of setup and its ability to secure a stable indoor environment without external energy even in harsh conditions. The ability to set it up with a small number of people and handle it without specialized training will bring significant changes to aid sites. We expect it to contribute to reducing environmental impact, improving the living environment for displaced people, and lessening the burden on aid workers.
Adoption of a Rail-Type Frame
"GREEN FLEX" adopts a "rail-type frame" where the membrane roof can be simply inserted into rails to cover the tent. The frame uses color labels to reduce errors in parts and an easy-connection slide-lock system, allowing anyone to assemble it easily. The frame has rails, and by inserting the membrane roof into these rails, the tent is completed.
This makes it possible to set up a large tent, which conventionally required many skilled personnel, in about 30 minutes with 6 people for "GREEN FLEX."
Flexible Depth and Membrane Roof
"GREEN FLEX" is a large tent with a width of 6m that can also function as a medical base. Its depth can be flexibly extended in 2-meter units. By using "REI KEEP" (manufactured by Kanboplus Co., Ltd.), a new membrane material developed by SPACECOOL Inc. that utilizes optical film with radiative cooling performance, an indoor environment less affected by external air is achieved. This suppresses temperature rise inside the tent even in high-temperature environments, contributing to improved comfort in shelter life and medical activities. Furthermore, by replacing the membrane material with one with high heat retention performance depending on the application and climate, it can also adapt to cold regions. In the future, the operation of a cooling device independent of external power sources, through the utilization of solar power generation modules assumed to be installed on the membrane roof, is also envisioned. As a verification step, demonstration tests of installing solar power generation modules on tents have already been conducted, and technical development for integrated implementation with the membrane material will be promoted going forward. It also contributes to environmental improvement from a "well-being" perspective, such as improving comfort and a sense of security in shelter life.
