Mandatory Stress Checks Expanding to Workplaces with Fewer Than 50 Employees: Official Release of "Mental Map," a High-Analysis System with 0 Yen Base Fees and 500 Yen per Person

On June 5, 2026, DAHTA Inc. officially launched the high-analysis stress check system "Mental Map." Following its beta launch in 2024, the system has been developed and improved based on feedback from industrial physicians, public health nurses, and corporate users, leading to this official release.

Mental Map is a next-generation stress check system characterized by three main features: (1) a transparent pricing structure with 0 yen base fees and 500 yen per person; (2) high analytical capabilities covering indicators not measurable by standard stress checks; and (3) simple operability that allows usage even without specialized personnel.

Background: Stress Checks to Become Mandatory for Workplaces with Fewer Than 50 Employees in April 2028 Previously, stress checks were only mandatory for workplaces with 50 or more employees. However, under the amended Industrial Safety and Health Act promulgated in 2025, workplaces with fewer than 50 employees—which were previously only under an obligation of effort—will be mandated to conduct stress checks starting April 1, 2028 (the first check must be completed by March 31, 2029).

Many small-to-medium enterprises newly subject to this requirement lack specialized internal resources like industrial physicians, public health nurses, or administrators, leading to concerns about where to start, costs, and operational burdens. Furthermore, even businesses already conducting these checks report issues such as not knowing how to use the results for workplace improvement or facing high costs for analytical options.

Mental Map is designed to help these businesses implement checks without hesitation and use the results to determine the "next step."

Three Features of the Official "Mental Map" Release Feature 1: 0 Yen Base Fees, 0 Yen Collective Analysis, and Only 500 Yen per Examinee There are no costs for implementation or collective analysis. The system can be used from 1 employee, costing only 500 yen per person. You can choose from 57, 80, 120, or 141 survey items with no additional cost for increasing the number of items. This pricing structure helps SMEs prepare for upcoming mandatory requirements without fixed costs.

Feature 2: High-Analysis Dashboard to Reveal the "Next Step" In addition to the standard 57 items, up to 141 items can be analyzed at no extra cost. The system supports time-series analysis by year and cross-departmental analysis to understand overall organizational trends. Furthermore, it visualizes data not covered by standard checks, such as presenteeism/absenteeism (productivity loss), work engagement, workplace safety, and comparisons with industry peers or age groups, all on one dashboard. An AI advice function suggests countermeasures for identified issues.

The system also includes standard support for engagement surveys conducted within the same system and workflow, allowing organizations to grasp their condition from both "mental health risk" and "organizational engagement/strengths" perspectives.

Feature 3: Designed for Field Operation Even Without Specialized Staff Even first-time administrators can complete the implementation by following the on-screen instructions. - Easy testing via QR code for employees without company email addresses (standard support for 13 languages, including support for technical interns and foreign workers). - Automatic reminders for non-examinees and automatic creation of reports for the Labor Standards Inspection Office. - Interview recording function to record and manage high-stress interviews by referencing past results. - Customizable account permissions based on roles (Corporate Administrator/Industrial Physician/Public Health Nurse/Administrator).

In addition, services such as operational support and administrative delegation for stress check implementation are available for businesses lacking internal resources.
