Tohoku University

Tohoku University is a national research university in Sendai, Japan, founded in 1907 and ranked #107 in the QS World University Rankings 2025. Its public, machine-readable developer footprint is centered on scholarly infrastructure rather than a central developer portal: the TOUR (TOhoku University Repository) institutional repository runs on NII's JAIRO Cloud (WEKO3) and exposes a live OAI-PMH 2.0 endpoint for metadata harvesting. The library also operates a public OPAC. No central, self-service API developer portal, open-data platform, or SSO/OAuth client-registration program was found publicly documented; most research-code APIs live in individual lab GitHub organizations.

Tohoku University publishes 1 API on the APIs.io network. Tagged areas include Education, Higher Education, University, Research, and Japan.

The Tohoku University catalog on APIs.io includes 1 JSON-LD context.

Tohoku University’s developer surface includes GitHub presence and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Education & Research regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/tohoku: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
