Japan’s Nobel wins shine light on worrying brain drain, especially to ‘generous’ China
Poor funding and job insecurity are pushing researchers abroad, where countries with deeper pockets actively seek top talent

On Monday, the Nobel Assembly announced that Shimon Sakaguchi and two American colleagues had been recognised for their “groundbreaking” discoveries on how the human immune system was kept in check. Two days later, Susumu Kitagawa became Japan’s 31st Nobel laureate for jointly developing with American and Australian colleagues porous materials that can store and release gases.
While the awards have been applauded domestically, an editorial in the Sankei Shimbun on Wednesday suggested that Sakaguchi’s work had been “generously supported” by the US scientific community and that his award “would not be possible in Japan’s current research environment”.
The editorial pointed out that Sakaguchi’s research was “unconventional” and that it took the 74-year-old 20 years to prove his theory, followed by a further 20 years before he won the Nobel.
“Scientific research in Japan has slowed significantly since the beginning of the 21st century,” it added. “In contrast to China’s rapid progress, Japan’s international ranking in the number of high-quality papers published has fallen to the lowest rank among developed nations. The situation is critical.”
