As an independent administrative institution, 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 constitute 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.
