We have launched a Medical Device Introduction “Partnership Program.”
This system connects companies with sales distributors interested in selling their products in the Japanese market.
Through this initiative, in addition to our existing Marketing Authorization Holder (MAH) outsourcing services, we will now also be able to support the sales and distribution of your products.

For companies that want to enter the Japanese medical device market but have difficulty moving forward due to a lack of a post-commercialization sales plan, we encourage you to consider using this program.
