Japan is reportedly testing solar-powered heated benches designed to provide warmth to people sleeping outdoors during cold winter nights.
According to viral reports circulating online, the benches are designed to collect solar energy during the day and store heat for release after sunset. Some versions of the story claim that the technology can provide warmth for up to 12 hours.
Tokyo and Sapporo are frequently mentioned as possible locations for the reported installations. The benches are said to use thermal-storage materials that absorb heat during daylight hours and gradually release it at night.
The idea has attracted attention because it combines renewable energy with a potential public-welfare application. Supporters of the concept say heated public furniture could provide temporary relief for people exposed to extremely cold weather without requiring a connection to the electricity grid.
However, the specific claims remain difficult to independently verify. Available fact-checking research has found no clear official confirmation from Japanese municipalities or research institutions identifying the project, its manufacturer, the number of benches installed or independent data confirming the claimed 12-hour heating period.
Japan does have solar-powered and smart public benches, while heated street furniture is also used in other countries. This may have contributed to the viral story being presented as a confirmed Japanese initiative.
For now, the heated-bench story should be treated as a reported or viral claim rather than a confirmed nationwide Japanese program.
