Japan's Stress-Check Mandate Is Expanding — and One Tokyo Firm Is Betting Companies Need Help Acting on the Results

Employers in Japan have spent years collecting workplace stress data. What many struggle with is what comes next.

Fractal Workout K.K., a Tokyo-based service provider led by Masahiro Takase, is positioning itself in exactly that gap. Under its "BODY PALETTE" programme, the company announced in mid-October 2026 that it has added a structured 90-day plan designed to carry organisations from the group analysis stage of a workplace stress check through to concrete improvements. The stated goal is to close the distance between gathering data and actually changing how a workplace operates.

Three months, three phases

The improvement plan runs on a fixed sequence. Month one is devoted to interpreting results and assigning specific tasks and responsibilities. Choosing suitable measures and securing internal approvals follows in month two. The third month brings the first practical rollout, along with a review of how it went.

Companies come away with two deliverables: a decision table for measures and an initial report.

Fractal Workout has been assisting employers with post-analysis health planning since August 2026. Alongside the 90-day plan, it offers an operational support programme aimed at tidying up stress-check processes that have stalled partway through. Existing contractors, implementing bodies and review systems stay as they are.

That programme produces a process-level responsibility chart and fills in steps that have been left unassigned — notifying employees of results, setting up a contact point for consultation requests, or carrying out the group analysis itself.

What Japanese law requires

Under rules set by Japan's Ministry of Health, Labour and Welfare (MHLW), companies with 50 or more employees must conduct a stress check once a year. For businesses below that threshold, the obligation takes effect on 1 April 2028.

Doctors or public health nurses carry out the checks. Where an employee with high stress levels requests it, a physician consultation is mandatory.

Individual results go directly to the worker and cannot be passed to the employer without that person's explicit consent — a safeguard for personal privacy. Group analyses, by contrast, are a duty of effort for employers, according to the ministry.

Those analyses must be conducted at a scale that makes it impossible to identify any single person. Small organisational units are therefore combined across several departments.

A second track: stopping falls before they happen

Fractal Workout is rolling out a separate 90-day plan through BODY PALETTE that targets falls in the workplace. It is aimed at safety and health officers in construction, manufacturing and logistics, and combines an on-site survey with a physical assessment of the workforce and an initial movement coaching session.

Pricing depends on participant numbers, frequency, locations and existing infrastructure. A further programme offers movement coaching with follow-up measurements over a 12-week period.

The rationale comes from labour ministry accident statistics: 135,333 people were injured or killed in workplace accidents in Japan in 2025 with at least four days of absence. Falls accounted for 37,195 of those cases — roughly 27.5 per cent of the total, making them the single most common cause.

A revision to the Industrial Safety and Health Act now obliges all companies to take measures to prevent workplace accidents among older employees, framed as a duty of effort.
