In 2009, JSPS received an endowment from His Majesty the Emperor Emeritus Akihito on the 20th year of his reign. Amidst a severe economic environment in Japanese society, His Majesty’s desire was to encourage and support young scientists who are working diligently to advance their studies and research.
In deference to his wishes, JSPS established the JSPS Ikushi Prize program and placed it into operation in FY 2010. It functions to formally recognize outstanding doctoral students who can be expected to contribute to Japan’s future scientific advancement.

All fields of the humanities, social sciences and natural sciences.

Candidates must be doctoral students with outstanding academic records, who possess abundant qualities of humanity and who pursue their studies and research in an independent and vigorous manner. They must be nominated by either the president of their university or the director of an academic society to which they belong. They must be enrolled in a university doctoral program on 1 May and be under 34 years of age on 1 April of the subject fiscal year.
Overseas students enrolled in university doctoral programs in Japan are also eligible.
