Latest Trends in the Medical M&A Industry
Since 2020, the number of succession M&A deals in Japan’s healthcare industry has rapidly increased. According to a survey by the Japan Medical Association, the average age of practicing physicians exceeds 60, with an estimated 40% facing a lack of successors. On the other hand, demand for succession by medical corporations and corporate groups is also expanding, leading to a record number of matching opportunities for both sellers and buyers.
- Demand for Clinic Succession: Over 1,000 M&A and business succession deals occur annually (estimated).
- Trend Towards Medical Corporation Structure: Increasing cases of succession after transitioning from individual practice to a medical corporation.
- Diversification of Potential Buyers: Medical corporation groups, business companies, independent-minded employed physicians, fund-related entities, etc.
- Impact of Regulatory Changes: Medical Act revisions, extension of the certified medical corporation system, and medical fee revisions influence succession strategies.
Considering these industry trends, early information gathering, consultation with experts, and timing are key to success.

Actual Support Cases
Related business succession and M&A examples supported by M&A Medical (partial, details omitted due to confidentiality agreements):
- Case A: Urban Clinic: A clinic with a 70-year-old director, facing a lack of successor, was transferred to a medical corporation group. All staff retained employment, and patient care continued. The process from consultation to closing took approximately 8 months.
- Case B: Rural Clinic: The region’s only clinic was sustained through succession by a nearby medical corporation, enabling the continuation of regional medical services. This was achieved through collaboration with a returning physician.
- Case C: Strategic Acquisition: An employed physician planning a new practice acquired an existing clinic with a favorable location, staff, and operating licenses. Medical services commenced within six months, saving approximately two years compared to establishing a new practice.
In each case, the desires of both the seller and buyer were reconciled, and specific issues unique to the healthcare industry (continuity of medical care, licenses, staff treatment) were carefully addressed.
