Planning Healthcare Research in Japan? Here’s What Makes the Market Different

When planning fieldwork in Japan, you’ll quickly realise it’s a market that needs  a slightly different approach to others.

Japan has one of the world’s most advanced healthcare systems, an ageing population, and a highly engaged medical community. These factors make it an incredibly valuable market for healthcare research, but they also mean successful studies rely on careful planning and local expertise.

So, what makes healthcare research in Japan different?

Japan Is a Market You Can’t Ignore

Japan is the world’s fourth-largest pharmaceutical market and home to one of the oldest populations globally. As healthcare needs continue to evolve, researchers are increasingly looking to Japan to understand physician behaviour, treatment pathways, patient outcomes, and the adoption of new therapies.

For organisations running multinational studies, Japan is rarely a market that can be overlooked. Instead, it’s often one of the most important countries to include.

Access Is Only Part of the Challenge

Researchers often need specialists with very specific clinical experience, availability, or patient exposure. With tight requirements, recruitment timelines can quickly become unpredictable without established local networks and an understanding of how Japanese healthcare professionals prefer to engage in research.

That’s why local knowledge, like we have here at ekas, is just as important as panel size.

Trust Plays a Bigger Role Than Many Researchers Expect

Healthcare professionals in Japan are selective about the research they choose to participate in.

Building trust, communicating clearly, and working through recognised professional networks can have a significant impact on participation rates and overall study quality.

That’s why local expertise isn’t simply a nice-to-have. It can directly influence recruitment success and the quality of your insights.

How ekas Supports Healthcare Research in Japan

We combine local market knowledge with the strength of one of the world’s largest healthcare communities.

As part of the M3 Group, ekas provides access to over 350,000 verified physicians, covering more than 90% of Japan’s physician population.

This unlocks access to healthcare professionals across a broad range of specialties and practice settings, helping simplify recruitment while maintaining high standards of quality and compliance.

Whether you’re conducting a local study or managing a global programme that includes Japan, our team works with you to find the right respondents and keep your research moving.

Looking Ahead

Healthcare research in Japan offers enormous opportunities, but success starts with the right local partner.
