Heat relief gear for car sleeping tested: Muji and Nitori
Original source: ダイヤモンド・オンライン

A Japanese outlet conducted a two-night test of heat relief products for sleeping in a car, using items from Muji and Nitori costing up to 5000 yen. On the first night at 33°C, the cabin temperature dropped to 25°C by morning; on the second night at 40°C, it stayed above 30°C. The test concluded that pre-cooling the cabin with air conditioning is essential, and that sleeping in a car should be avoided during extreme heat due to heatstroke risk.

2026 Kumamoto earthquake: power outages, water cuts, many victims outside shelters

According to the Kumamoto Prefecture Disaster Response Headquarters, as of 6 a.m. on January 30, about 10,000 people from 4,000 households were staying in approximately 400 designated evacuation centers across 30 municipalities. However, these figures do not include those sleeping in vehicles or sheltering at home, and the actual number of affected people is believed to be higher. In heavily damaged areas such as Hikawa Town and Uki City, schools and disaster prevention centers that would normally serve as shelters were themselves damaged by the earthquake and power outages, delaying their opening.
