DMAH: Designated Marketing Authorization Holder-Summary Ver.
A DMAH lets a foreign medical device or IVD manufacturer sell products in Japan and hold the marketing approval in its own name — without setting up a Japanese entity.
1. Three Regulatory Pathways — Determined by Your Product
Which regulatory pathway your product takes is not a choice. It follows from the JMDN (Japanese Medical Device Nomenclature) code assigned to your device, the class that code carries, and whether a certification standard exists for it. PMDA publishes the JMDN list and the certification and approval standards in English, so you can check all three yourself.
| Class I | Class II | Class III | Class IV | |
|---|---|---|---|---|
| Statutory category | General medical device | Controlled medical device | Specially-controlled | Specially-controlled |
| Pathway | Notification (todokede) | Certification if a standard exists; otherwise Approval | Certification if a standard exists; otherwise Approval | Approval (shonin) |
| Marketing licence needed | Type 3 | Type 2 | Type 1 | Type 1 |
| Foreign Special scheme | None | Available | Available | Available |
| DMAH | Cannot be appointed | Required | Required | Required |
Marketing licences are cumulative: a company holding a higher type is deemed to hold the lower ones. A DMAH with a Type 1 licence can therefore handle products in any class.

2. The Foreign Special Approval / Certification Scheme
Normally a Japanese approval or certification is held by a Japan-based marketing authorization holder in its own name, but the foreign special approval and certification scheme is the exception: it lets a foreign party hold it in its own name (PMD Act Art. 23-2-17; Arts. 23-2-23 and 23-3). The scheme also provides for appointing a Japan-based marketing authorization holder, at the time of application, to carry the responsibilities inside Japan. That appointed company is the DMAH.
「外国特例承認(認証)を受けた(受ける)者は、本邦内の必要な措置を採らせるために製造販売業者を選任する必要があります。」
"A party that has obtained, or is obtaining, a foreign special approval or certification must appoint a marketing authorization holder so that the necessary measures are taken within Japan."

Note: When the Foreign Special Scheme Does Not Apply
- Class I (general medical devices) — These go through notification, not approval or certification, and the notification route has no foreign-manufacturer counterpart. Here you contract with a conventional MAH, which files the notification in its own name and places the product on the market.
- Products manufactured in Japan — The scheme is written for devices exported to Japan by a manufacturer located outside Japan, so a product made in Japan falls outside it by definition. Here too, a conventional MAH obtains the approval or certification in its own name and places the product on the market.
In both cases the registration sits with the MAH, not with you. That is the practical difference from using the foreign special scheme. Changing partners means a formal transfer of the approval or certification, or — for a notification — filing a fresh notification and withdrawing the old one. Either way, it depends on your outgoing partner's cooperation.
「一般医療機器に外国製造医療機器製造販売承認と同等の制度はありません。必ず日本国内の製造販売業者が届出者となります。」「承継の制度はありませんので、製造販売を引き継ぐ者が新たな製造販売届書を提出し、以前の届は適宜廃止してください。」
"For general medical devices there is no system equivalent to marketing approval for foreign-manufactured medical devices. The notifier must always be a marketing authorization holder located in Japan." / "There is no succession procedure. The party taking over marketing must file a new marketing notification, and the previous notification should be withdrawn."

"The exception lets a foreign business obtain approval (or certification) for a medical device or IVD that it exports to Japan." / The party eligible for foreign special certification is defined as "a person who manufactures, outside Japan, designated controlled medical devices etc. that are exported to Japan — namely the specially-controlled, controlled, or in-vitro diagnostic devices designated by the Minister of Health, Labour and Welfare" (PMD Act Art. 23-2-23, para. 1).

3. What Is a DMAH, and What Does It Do for You?
A DMAH (Designated Marketing Authorization Holder / 選任外国製造医療機器等製造販売業者) is a licensed Japanese company that acts as your legal representative in Japan under the foreign special approval and certification scheme. You — the foreign manufacturer — hold the approval yourself. PMDA's English materials call this party the FRAH, the foreign restrictive authorization holder.
"Foreign restrictive authorization holder: FRAH — A foreign manufacturer who obtains the marketing approvals of medical devices in foreign country. FRAH may designate licensed MAH in Japan and have it market the product."
"Designated MAH: DMAH — MAH designated by FRAH to conduct required quality control duties inside Japan."

A DMAH handles the full regulatory lifecycle in Japan on your behalf:
- Regulatory filings — Marketing approval and certification applications, STED (Summary Technical Document/技術文書概要) preparation, and QMS (Quality Management System/QMS省令) conformity assessment
- Foreign Manufacturer Establishment Registration(医療機器等外国製造業者登録, FMER)— filed by the DMAH as your agent. You remain the applicant; a foreign manufacturer cannot file directly.
- Quality control (QMS/QMS省令) — Incoming inspection, release decision, and domestic quality oversight
- Post-market safety (GVP (Good Vigilance Practice)/GVP省令) — Adverse event collection and reporting to the PMDA, recall reporting and management, annual periodic reports, and reporting of overseas actions such as recalls or field corrections taken in other markets
- Labeling, electronic package inserts & promotion — Preparing and updating the electronic package insert (電子添文, published on the PMDA website), statutory Japanese labeling on the device and its packaging, and review of promotional materials
- Authority liaison — Direct communication with PMDA, MHLW, and certification bodies(登録認証機関)
「外国製造業者の登録の手続については、申請者は外国製造業者になりますが、原則として当該外国製造業者が製造する医療機器等の日本国内における製造販売業者が『代行者』となり申請書を提出することになります。」「外国製造業者が代行者を介さず直接提出することはできません。」
"The applicant is the foreign manufacturer; as a rule, however, the marketing authorization holder in Japan for the devices concerned acts as the agent and submits the application." / "A foreign manufacturer cannot submit the application directly without going through an agent."

4. DMAH vs. MAH: How the Two Routes Differ
Which route you take depends on whose name the approval is held in: the DMAH route or the MAH route.
The DMAH route
You hold the approval, and the DMAH carries out the regulatory work inside Japan.
The MAH route
A Japan-based company holds the approval in its own name. That company may be your distributor, your contract manufacturer, a specialist regulatory service provider, or your own Japanese subsidiary. The same firms that act as DMAHs also act as MAHs.
The DMAH route cannot be used for Class I devices, which go through notification, or for products manufactured in Japan. Beyond that, the players involved and the licences required are the same in both routes, and the difference comes down to a single point: whose name is on the approval. On the DMAH route the approval stays with you and does not move when you change partners. On the MAH route the approval is that company's asset, and moving it takes a formal transfer and their cooperation.
5. Why DMAH is the Best Route for Foreign Manufacturers
The killer advantage of DMAH is a dramatically faster, leaner start. You retain control of your product approval while outsourcing the complex Japanese regulatory work.
- No Japanese entity required — Skip the cost and time of establishing a company, securing an office, hiring the three statutory controllers ("San-yaku"/三役) required by the PMD Act, and obtaining a medical device marketing authorization licence.
- You keep the approval in your name — The approval never sits with a commercial partner. If your commercial relationships change, your market access stays with you.
- Regulatory expertise, bought in — Companies offering DMAH services work with Japanese regulatory requirements day to day: choosing the right application category, assembling the documentation, and handling QMS conformity assessments. You spend no time climbing the learning curve, and your own team stays focused on the product and the business.
