University of Tokyo

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.

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