Inside The University of Tokyo's largest research partnership: Kyoto University
Behind The University of Tokyo's research output sits a defining relationship: 4,566 co-authored works with Kyoto University (Japan) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 1,179 collaborating institutions across 80 countries, producing 97,427 joint works over the window, with international co-authors on 31% of output.
The collaborative work travels: its field-weighted citation impact stands at 2.55, where the world average is 1.0.
The Research Collaboration Index, the first global account of how universities actually collaborate, published its first full edition on 15 September 2026. The full results are public.
Every figure derives from the open global research record and is checkable at source.
