Purpose of the Study:

• To quantify Japan's contribution to basic and clinical research over a decade (1990-2000).
• To identify trends in Japanese research output in these fields.

Main Methods:

• A bibliometric analysis of original articles published between 1990 and 2000.
• Data sourced from the MEDLINE database, focusing on articles with Japanese institutional affiliations.
• Separate counts for basic and clinical research contributions.

Main Results:

• Japan contributed 3.1% to basic research and 0.7% to clinical research.
• A significant increase in basic research contribution was observed.
• No significant increase was noted in clinical research contribution.

Conclusions:

• While basic research shows positive trends, clinical research in Japan faces challenges.
• Identifying and addressing barriers to high-quality clinical research is imperative.
• Strategic measures are needed to enhance Japan's clinical research output.
