New Version of "hitoe® Heat Stroke Prevention Service for Cloud" Released

NTT TechnoCross Corporation (Head Office: Minato-ku, Tokyo; President and CEO: Atsuko Oka; hereinafter "NTT TechnoCross") will release a new version of its "hitoe® Heat Stroke Prevention Service for Cloud" in late April 2026. This service enables risk management for workers' health in hot environments by linking the wearable sensor "hitoe®" with a smartphone application to acquire biological, environmental, and exercise information.

■ Background

The revised Industrial Safety and Health Act will come into effect on June 1, 2025, to strengthen measures against heatstroke in the workplace. For work in environments with a WBGT (*1) of 28°C or higher, or an air temperature of 31°C or higher, for more than one consecutive hour or more than four hours a day, employers are obligated to "establish a system," "create procedures," and "inform relevant parties" to promptly identify workers at risk of heatstroke, take appropriate measures, and prevent serious illness.

Serious cases of heatstroke are often caused by ignoring initial symptoms or delaying response. It is crucial to quickly implement basic responses on-site: "finding," "judging," and "acting." Therefore, workplace patrols, the buddy system, and the use of wearable devices are recommended.

Until now, our company has offered the "hitoe® Heat Stroke Prevention Service for Cloud," which detects and manages changes in workers' physical condition at an early stage by linking the "hitoe®" wearable sensor attached to the chest with a smartphone application. This service consists of a management function that allows supervisors to monitor the status of multiple workers, including those in remote locations, from a single web system screen, and a mechanism for individual workers to check their own physical condition using a smartphone app. The new version has been enhanced with additional functions to comply with the revised Industrial Safety and Health Act, making it easier for both managers and workers to implement measures in line with the regulations. This will contribute to improving labor management by enabling the early detection of risks related to the poor health of multiple workers, including those in remote locations, and the implementation of appropriate responses.

■ Features of the New Functions (Mapping to Employer Obligations)

(1) Strengthening Workplace Patrols and Communication for Anomaly Detection (Support Function for System Establishment)

In addition to the worker's heart rate, managers can view information such as temperature and humidity in real-time to detect risks related to a worker's poor health at an early stage (*2). This helps managers efficiently grasp the health status of the workplace and supports the establishment of a system for prompt responses.
