  The University of Tokyo (UTokyo) is Japan's leading national research
  university, founded in 1877 and ranked #29 in the QS World University
  Rankings 2025. Its public, machine-readable developer footprint is centered
  on its library and digital humanities infrastructure rather than a unified
  developer portal. Confirmed public APIs include the UTokyo Academic Assets
  Archives (utda) Digital Archive Portal, which exposes IIIF-compliant image
  and presentation APIs plus downloadable IIIF Collections and JSON-LD/RDF
  metadata datasets, and the UTokyo Repository (WEKO) institutional repository,
  which offers an OAI-PMH 2.0 metadata harvesting endpoint. No general-purpose,
  authenticated REST developer program (course/SIS/timetable APIs) was found
  publicly documented.
