Objective To investigate the degree of Japan's contribution in basic and clinical research in the last decade.
Methods Original articles published in 1990-2000 in highly reputed basic and clinical journals were accessed through MEDLINE database. The number of articles having affiliation with a Japanese institution was counted separately for basic and clinical journals.
Results Of total articles, Japan's contributions in basic and clinical research were 3.1% and 0.7%, respectively (p=0.0001). The recent increase in the contribution was significant for basic research (p=0.01), but not for clinical research (p=0.91).
Conclusion The barriers to boosting high quality clinical research in Japan should be determined and accordingly appropriate measures should be taken forthwith.
