Excel Creates Co., Ltd. (Headquarters: Osaka; CEO: Makoto Tanada), a developer and provider of software for medical institutions, has concluded the 2025 fiscal year distribution period for its 'Bathing Alert Information' service, conducted in collaboration with Professor Takahito Hayashi of Kagoshima University, as of the end of February 2026. This free service notifies users of heat shock risk levels via LINE in three stages: 'Caution,' 'Alert,' and 'Danger.' The service began in the 2023 fiscal year and is distributed within Kagoshima Prefecture annually from November to the end of February.
In the 2025 fiscal year, improvements in functionality and strengthened awareness campaigns led to confirmed results in both the number of subscribers and behavioral changes among users.
■ 2025 Fiscal Year Functional Improvements
In the 2025 fiscal year, two functional improvements were implemented to deliver risk notifications to more people and enhance the effectiveness of heat shock prevention:
1. Expansion of Distribution Scope
Previously, bathing alert information was only sent to users who had completed registration for all seven items of user information. To provide information to a wider audience, the scope was changed so that users can now receive alerts by registering only their 'residential area,' even if the full registration is not complete.
2. Notifications Limited to 'Alert' and 'Danger' Levels
The system was changed to send notifications only during 'Alert' and 'Danger' levels, where the risk is particularly high. By reducing the frequency of notifications, the company aimed to prevent desensitization and encourage behavioral changes at critical times.
■ 2025 Fiscal Year Results
- Trends in Subscriber Numbers
The total number of subscribers increased from 536 to 677, a 26% increase from the previous fiscal year. With those aged 65 and over accounting for approximately 90% of fatal bathing accidents, a challenge for the service was the low number of subscribers in that age group. Consequently, efforts were focused on promoting usage among the elderly, resulting in a 45% year-on-year increase in subscribers aged 70 and over. Notably, the number of subscribers aged 80 and over, which had previously been low, also saw growth.
