Japan Consumer Affairs Agency warns of mobile battery fire risks

A survey released by Japan's Consumer Affairs Agency on September 17, 2026, reveals that while 84.5% of respondents are aware of the fire risks associated with lithium-ion battery products, safety is not always the primary purchasing factor. Among users, 51.2% prioritized price when buying mobile batteries, while only 36.3% prioritized safety.

The survey, which included 5,000 participants aged 15 and older, also highlighted gaps in safety awareness across age groups. While 90.8% of those in their 70s were aware of the risks, only 72.0% of those in their 20s reported the same. Regarding usage habits, approximately 54.7% of users take precautions against high temperatures, but only 7.6% check for product recall information.

Data from NITE indicates that between 2020 and 2025, there were 1,860 reported fire accidents involving mobile batteries, with approximately 85% of those incidents escalating into actual fires. Common causes include physical impact, exposure to heat, and leaving devices charging unattended. In response, the Consumer Affairs Agency has issued public warnings and posters to encourage safer usage and regular checking of recall notices.
