Designated Marketing Authorization Holder (DMAH)
Service for Medical Device Japanese

◉ Japanese Marketing Authorization Holder (MAH)

Japan’s Pharmaceuticals and Medical Devices Act (PMD Act) defines the Marketing Authorization Holder (MAH) as the legal manufacture in Japan. Consequently foreign manufacturers are not able to wholesale or sell medical device directly to distributors.

The MAH requirements for Quality and Safety control management are strict more than for example ISO 13485, 21 CFR Part 820. The MAH must be located in Japan, formally licensed by the prefectural (regional) government, and employ qualified persons, such as General Manager, a Quality Manager and a Safety Manager.

MAHs must also implement a Quality Management System based on MHLW Ordinance No. 169 (Japan QMS Regulation) and Good Vigilance Practices (GVP).
Japanese Marketing Authorization Holder license is classified to four class and handling medical devices are also different.


◉ Foreign Exceptional Approval System and DMAH

Japan’s Ministry of Health, Labour and Welfare (MHLW) permits manufacturers of Class II, III, and IV medical devices to register their product through the Foreign Exceptional Approval System. This registration route allows the foreign manufacturer to be a Foreign Restrictive Authorization Holder (FRAH), and to register their product under their name, instead of the MAH’s name. And FRAH must appoint a Designated Marketing Authorization Holders (DMAH) who will take regulatory responsibility for activities outlined in the Japan QMS and GVP Regulations stated in PMD Act 72-3.


◉ Marketing Authorization Holder : MAH

・A person who obtains the marketing license. MAH shall supervise and manage the manufacture, and ensure the compliance with QMS of all manufacturing sites. Ensure proper product release to the market. MAH must be in Japan.

◉ Foreign Restrictive Authorization Holder : FRAH

・A foreign manufacture 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 Marketing Authorization Holder : DMAH

・MAH designated by FRAH to conduct required quality control duties inside Japan. FRAH shall have DMAH take necessary measures for the prevention of occurrence of hazards to the public health and hygiene in Japan caused by the product.

◉ Why select an Independent DMAH versus a distributor as the MAH?

While it is possible to appoint a distributor as the MAH (Distributor MAH) in Japan, there are many reasons why selecting a distributor as your MAH should be reconsidered, including

・The Distributor MAH controls your device approval which gives them full control over your device approval in Japan.

・Selecting an independent DMAH allows flexibility in the selection of distributors and allows for more control over those distributors and their networks. It prevents that your distributor has full control over the commercialization of your devices in Japan.

・If you decide to change distributors, you may have to re-register your devices again for approval. This is costly, time consuming and may result in being (temporarily) off the market until you have obtained new approval.

・The MAH/DMAH must have full access to your device technical information, which may include proprietary design information. The DMAH is capable of keeping this information confidential and prevents the necessity of sharing this information with a distributor.
