Postdoctoral Research in Japan: Opportunities, Benefits, and How to Apply
Diah Anggraini Wulandari Updated in JULY 2025

Japan offers exceptional opportunities for postdoctoral researchers, particularly for those passionate about scientific advancement, innovation, and international collaboration. As a member of the Sakura Science community, you are in a unique position to take advantage of these opportunities. One of the main attractions of pursuing a postdoc in Japan is the country's advanced research infrastructure, strong academic culture, and the high productivity of Japanese professors in publishing scientific papers. Japan also provides an environment that strongly supports international researchers in achieving publication success in well-respected journals.

Among the most prestigious programs available is the Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellowship. This program is open to researchers from all over the world and provides generous financial support for a period of 12 to 24 months. Eligibility requirements include holding a PhD obtained within the last six years and being a citizen of a country that has diplomatic relations with Japan. Please note that previous recipients of JSPS fellowships or those with Japanese citizenship or permanent residency are not eligible. Applicants may also subtract time taken for maternity or parental leave from the six-year eligibility window. Successful applicants are required to submit proof of their doctoral degree before the fellowship begins.

The benefits of the JSPS Fellowship include a round-trip airfare, a monthly maintenance allowance of JPY 362,000, a settling-in allowance of JPY 200,000, as well as overseas travel insurance. To apply, researchers must first secure a host in Japan. The host researcher must be affiliated with an eligible research institution and able to provide appropriate research facilities and supervision. Hosts can submit up to three applications per round, and applications are accepted twice a year, typically in April and August. Full details and requirements can be found on the JSPS website: https://www.jsps.go.jp/english/e-fellow/e-ippan/index.html

In addition, JSPS also offers a Summer Program and a Short-Term Fellowship specifically aimed at researchers in the humanities, social sciences, and natural sciences from ASEAN and African countries. These programs provide further flexibility and options for early-career researchers to explore Japan's vibrant academic landscape.

Beyond JSPS, numerous universities and research institutions in Japan offer postdoctoral positions. For instance, you can explore opportunities at Kyushu University by visiting their webpage https://ias.kyushu-u.ac.jp/en/recruits/ . If you’re interested in pursuing a postdoctoral position in Japan, I recommend visiting the websites of specific institutions or research centers and reaching out directly to potential supervisors.

As someone currently working in a Japanese lab, I can personally say that doing research in Japan is a truly enriching experience, both professionally and culturally. The environment is collaborative, well-resourced, and inspiring. I’m excited to invite more Sakura Science alumni to explore the possibility of continuing their research journey here. Let’s reconnect in Japan and advance science together!
