ISO 45001 certification in Japan at a glance
Guidelines on Occupational Safety and Health Management Systems (MHLW), revision applied from 1 July 2019 refers to ISO 45001, yet none of the Japanese instruments checked makes it compulsory. Buyers in Japan ask for it anyway.
Japan's Ministry of Health, Labour and Welfare revised its guideline on occupational safety and health management systems, applied from July 2019, after ISO 45001 was adopted as JIS Q 45001 and the companion JIS Q 45100 was issued in September 2018. JIS Q 45100 lists specific safety and health activities and health measures drawn from Japanese practice, so a system built to both standards fits domestic expectations as well as the international one. The guideline itself remains rooted in the Industrial Safety and Health Regulations and does not require certification; the certificate is a choice driven by customers, contractors and group policy, particularly in construction and manufacturing. Certification is granted by an accredited certification body, for example one accredited by the Japan Accreditation Board, after stage 1 and stage 2 audits that look closely at hazard identification, worker participation and legal compliance. Sterling supports the system from the Tokyo office, with Effivity and Sterling Academy included in the engagement.
Who needs ISO 45001 in Japan, and what happens without it
In Japan the question rarely comes from a law. It comes from the buyer, the regulator or the partner that wants proof before it signs. These are the organisations that get asked.
- Employers running an OSHMS under the MHLW guidelineThe guideline was revised in light of ISO 45001 and JIS Q 45100.
- Construction and manufacturing firmsCustomers and contractors ask for a certified OH&S management system.
- Groups standardising safety management across Japanese and overseas sitesISO 45001 gives one international framework, with JIS Q 45100 adding Japanese practice.

Strip away the vocabulary and ISO 45001 requires a company to prove six things about keeping its people safe and healthy at work.
In Japan these six sit alongside the local laws and regulations listed under drivers below; one system can evidence both. The detail is on the global hub: ISO 45001 explained →

The Sterling Promise: 100% on-time completion, 100% success, 8,100+ client engagements.Sterling does not certify. Certification decisions stay with independent bodies.
How long does ISO 45001 certification take in Japan?
There is no standard duration: it depends on your scope and on how much of the system already runs. In Japan these are the factors that set the timeline.
- Number of sites and high-risk activities in scope
- Risk assessment and legal register under the Industrial Safety and Health Act
- Worker consultation and participation evidence
- Certification body scheduling around Japanese holiday periods
Sterling agrees a dated plan with you on the discovery call, once the scope is known.
How much does ISO 45001 certification cost in Japan?
The cost has two parts: the consulting work to build and prove the system, and the certification body’s audit fees, which are quoted separately. In Japan these factors move both.
- Number of sites, employees and contractors
- Certification body audit fees quoted separately from consulting
- Whether JIS Q 45100 items are included
- Integration with ISO 9001 and ISO 14001
Sterling gives one customised, all-inclusive proposal after the discovery call, never before the scope is agreed.
ISO 45001 consultants and certification bodies in Japan
Two different organisations are involved. A consultant helps you build the system and prove it works; an accredited certification body then audits or assesses it and decides. Keeping the two separate is what makes the result credible to buyers and regulators.
- Check that the body’s accreditation or approval covers ISO 45001 and your sector, and that its certificates can be verified online.
- Ask the consultant how the local requirements in Japan are mapped into the same system, so nothing runs twice.
- Ask for client references in your sector; Sterling’s client letters are available on request.
- Agree who owns the evidence and the tool after the engagement; with Sterling the system stays yours, in Effivity.

Accreditation, audit language and remote audits in Japan
Use a certification body accredited for this standard by JAB or by another accreditation body within the international mutual recognition arrangements (Global ACI — Global Accreditation Cooperation Incorporated, formerly the IAF MLA); check that the accreditation scope covers the standard and your sector. No body is named here unless its accreditation scope in Japan has been verified. Edition and transition details: ISO 45001 hub →
Audit language
Japanese or English; agree the audit and document language with the certification body at application (JIS Q editions of the standard are available in Japanese).
Remote and on-site
Remote audit elements are at the certification body's discretion under its accreditation rules; operational sites are normally visited on-site.
ISO 45001 in Japan: questions clients ask
What is JIS Q 45100?
JIS Q 45100 is a Japanese standard issued in September 2018 alongside ISO 45001, which Japan adopted as JIS Q 45001. It lists specific safety and health activities and health measures. The MHLW revised its occupational safety and health management guidelines in light of both documents, so they are worth reading together.
Does the MHLW OSHMS guideline require ISO 45001 certification?
No. The guideline is issued under the Industrial Safety and Health Regulations and was revised in light of ISO 45001, but it does not require certification. Employers can follow it without a certificate. Certification is a voluntary choice, normally driven by customers or tenders.
Who issues ISO 45001 certificates in Japan?
Certification bodies accredited for ISO 45001, by JAB or by another accreditation body within the international mutual recognition arrangements. Look at the body's accreditation scope and make sure it covers your sector. A consultant can prepare the system, but only the accredited body issues the certificate.
