Inside M3, Inc’s journey through digital healthcare platforms

M3 was established in Japan in September 2000 as So-net M3, initially using the internet to connect pharmaceutical companies with medical professionals.

How M3, Inc developed

The company launched the MR-kun service in 2000 and expanded m3.com as an online professional network for doctors. It listed on the Tokyo Stock Exchange’s Mothers market in 2004 and moved to the First Section in 2007 while expanding healthcare services internationally.

M3, Inc in 2026

By 2026, M3 operated digital healthcare platforms that connect physicians, pharmaceutical companies, clinical research organisations and other healthcare participants.

M3 is an example of a specialised professional network becoming infrastructure for marketing, research and healthcare services rather than remaining a simple information website.
