Diversity is at the heart of RIKEN's research environment, and this is no better illustrated than in the strong numbers, by Japanese standards, of international and female staff who play a vital role in RIKEN's success today.

Non-Japanese scientists working at RIKEN come from all over the world. The two largest groups come from two of Japan's closest neighbors, China and Korea, while there are also a significant number from the United States, India, and European countries.

As a national research and development institute, RIKEN receives the bulk of its funding from the Japanese government. The largest proportion of RIKEN's income is derived from government grants that fund RIKEN's general operations and facility maintenance. Government subsidies for the operation and construction of major facilities have constituted a significant proportion of total income over the past several years.

RIKEN also strives to generate income through competitive grants and from collaborations with industry or royalty income.
