  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.
