Mysurance Inc. (Head Office: Shinjuku-ku, Tokyo; Representative Director and President: Hiroomi Shimizu; hereinafter referred to as "Mysurance"), a subsidiary of Sompo Japan Insurance Inc. (Head Office: Shinjuku-ku, Tokyo; Representative Director and President: Koji Ishikawa; hereinafter referred to as "Sompo Japan"), engaged in the short-term small insurance business, conducted a survey targeting 1,000 men and women aged 20 to 59 residing in rental housing nationwide, titled "Survey on Awareness of Safe Use of Mobile Batteries and Liability Risks."
Through the results of this survey, conducted from the unique perspective of an insurance company, we sincerely hope to provide an opportunity for people to reconsider the liability risks hidden in everyday products, bring about a change in awareness for as many people as possible, and lead to the safe and secure use of mobile batteries.
1. Background of the Survey Implementation
In recent years, while mobile batteries have become widely popular as essential daily items, numerous fire accidents caused by products have been reported, increasing concern for safety. In December 2025, under the leadership of the Ministry of the Environment, the "Comprehensive Package for Lithium-ion Batteries" was formulated, and measures are being promoted with the government as a whole. Furthermore, the Ministry of Land, Infrastructure, Transport and Tourism has announced new rules, effective April 24, 2026, aimed at reducing the risks associated with mobile batteries, including prohibition of charging inside passenger aircraft and restrictions on carry-on items, further increasing the importance of this theme socially.
In fact, our "Smart Rental Fire Insurance," which we provide to residents of rental housing, has also received accident reports originating from products using mobile batteries or lithium-ion batteries, with cases confirmed where not only small fires but also entire buildings have been completely burned down.
We, as a company, support these government initiatives and awareness campaigns, and we conducted this survey with the aim of providing an opportunity to reconsider the liability risks hidden in everyday products and broadly communicate the importance of preparing for unforeseen circumstances.

3. Survey Content (Details)
Lack of Proper Management Revealed Amidst Widespread Use: One in Four Recognizes the Existence of "Lost Batteries"
It became clear that 58.8% of people own "one or more" mobile batteries, revealing their widespread penetration into daily life. On the other hand, 26.5% of owners responded that they have forgotten the location of their mobile batteries, stating, "There might be one lying dormant at home," or "I don't know."
This result indicates that approximately one in four households may have mobile batteries that are not properly managed within the home, highlighting a reality that cannot be overlooked from the perspective of ignition and accident risks.
Indeed, accidents where unused mobile batteries left for long periods suddenly ignite have been reported, once again raising the question of the importance of proper management, including storage conditions.
Significant Gap Between Understanding and Action Regarding the Safety Mark "PSE Mark"
"People who understand the meaning and check it when purchasing" account for 22.5% of the total (1 in 5 people).
The "PSE Mark," which is required to be displayed on products that meet safety standards under the Electrical Appliance and Material Safety Act, is one of the important indicators of product safety. However, among mobile battery owners, only 40.2% in total responded that they "know" the meaning of this mark, and only 22.5% in total "understood the meaning and checked it at the time of purchase."
In other words, even if they understand the meaning of the "PSE Mark," the number of people who actually check it during purchase is even more limited, revealing a significant gap between understanding the PSE mark and taking action.
On the other hand, about 60% of respondents answered, "I don't know," or "I've seen it but don't know what it means," indicating that they may be using products without fully understanding the safety labels. These results demonstrate the importance of promoting understanding for safe product selection.
