The JSPS carries out programs that provide overseas researchers who have an excellent record of research achievements with an opportunity to conduct collaborative research, discussions, and opinion exchanges with researchers in Japan. These programmes are intended to help advance the overseas researchers' research activities, while promoting science and internationalization in Japan.
This program is designed to enable Japanese researchers to invite their foreign colleagues to Japan to participate in cooperative work. Researchers from all countries with diplomatic relations with Japan and of any field of study are eligible.
Applications must be submitted to JSPS by the inviting researchers who wish to host foreign researchers in Japan, through an overseas nominating authority. A list of nominating authorities in partner countries such as France, Germany, Hungary, Italy, the Netherlands, Norway and Sweden (for Europe) are listed here.
Various fellowship categories are provided: three for postdoctoral fellowships and three for invitation fellowships (researchers). Approximately 320 postdoctoral fellowships and 290 invitation fellowships should be awarded for 2015 through 2 to 4 calls (see here for further details on the different categories).
Next application rounds: 6-10 April (Short-term postdoctoral)
28 April - 8 May (Standard postdoctoral)
28 April - 8 May (Short-term invitations)
(see here for a list of the future calls)
