Nature Index has published a supplement on Japan indicating that the country’s research output has stagnated over the last few years both relatively and absolutely. Between 2005 and 2015 Japan’s world share of research articles fell from 8.4% to 5.2%. In contrast, the number of papers produced in China has increased remarkably.
Although the government has attempted to attract leading international scientists most universities have responded to government austerity measures by reducing staff numbers and the opportunities for early career researchers.
Among Japanese institutions, the Index shows that the University of Tokyo continues to be dominant in research followed by Kyoto University.
The top ten universities overall according to the weighted fractional count of articles published in high quality journals are:
- University of Tokyo
- Kyoko University
- Osaka University
- Tohoku University
- Tokyo Institute of Technology
- Nagoya University
- Kyushu University
- Hokkaido University
- National Institute for Materials Science.
Tables are also provided for life sciences, chemistry, earth and environmental sciences, and physical sciences and for academic, healthcare, corporate, and government/ not-for profit institutions.
The top institutions in each categoryare:
Life sciences: University of Tokyo
Chemistry: Kyoto University
Earth and environmental sciences: University of Tokyo
