Other trial registries in Japan

This register lists Japan studies from ClinicalTrials.gov. Many studies in Japan are registered only in a national registry. We do not copy those records; search them directly:

  • jRCT (Japan Registry of Clinical Trials) — run by the Ministry of Health, Labour and Welfare; trials under Japan's Clinical Trials Act and other clinical research
  • UMIN-CTR — run by the University of Tokyo Hospital's UMIN Center; many academic and investigator-led studies
Listing here is informational and not medical advice; eligibility is determined by each study team. See also the Ireland, UK, EU, USA and China registers.
