Overview
- The walk‑in booth went on sale in Japan in April and has drawn renewed attention in mid‑July as the country faced record summer heat and clusters of heatstroke hospitalisations.
- Manufacturers report the unit keeps its cabin around 15°C and directs air cooled to about 5°C at the head, neck and back, with users feeling cooler in 5–10 minutes and sessions automatically limited to 20 minutes.
- The standard model is priced at roughly ¥1.5 million and is marketed to construction sites, factories, warehouses and municipalities rather than households.
- Makers say the cabin runs on a normal power outlet, sits on casters for easy movement, claims about half the electricity use of a typical spot air conditioner, and has already been placed in some public venues such as Maebashi City Hall.
- Early coverage shows inconsistent attribution of developer and distributor names (reports alternate between SDRS and TRUSCO Nakayama and between the Do Hiemon and Do Reimon names), and companies stress the booth is a rapid cooling aid not a medical treatment while wider adoption and overseas availability remain unclear.
