Japan Registry of Clinical Trials (jRCT), run by Japan’s Ministry of Health, Labour and Welfare: search and fetch the registry’s trial records, with Japanese and English titles, status, phase, condition, intervention, sponsor organisation, sites and dates.

Tools

• jp_jrct_search(query, status?, match?, page?, limit?) — free-word search over the registry’s records in Japanese or English (full-width and half-width forms folded). All words must match by default (match=any for either). Each hit gives the jRCT number, the title (cut at 30 characters by the registry’s list), condition, status (pending, recruiting, suspended, recruitment_ended, complete), publication date and the record links. 50 results a page.
• jp_jrct_get(trial_id) — one record by jRCT number: full Japanese and English titles, status, phase, study category, condition, intervention and generic drug names, sponsor organisation (for investigator-initiated research, the coordinating investigator’s affiliation, labelled as such), study type, planned sample size, number of sites listed, other countries recruiting, dates, the number the trial holds in another registry, and the public-query contact organisation and department.

Investigator and contact persons’ names, e-mail addresses and telephone numbers are deliberately not returned; the record links carry what the registry publishes.

Data sources

• Ministry of Health, Labour and Welfare (Japan), Japan Registry of Clinical Trials (jRCT): read live, one request per call, nothing stored.

The registry asks that its data not be bulk-collected by program, and its front end blocks repeated automated requests for a while (HTTP 403 “Request blocked”). The pack never pages by itself; a block surfaces as a refusal naming it, not as “no trial”. The registry answers an unknown trial number with an internal-error page (HTTP 500), which it also gives on a fault, so an unknown number is reported as unknown_id_or_registry_error rather than as a confirmed absence. The registry covers trials run in Japan; the same trial may also sit in ClinicalTrials.gov (see other_registry).
