One of my junior colleagues shares information about a grant from Japan. From Toyota Foundation. There are certain requirements though. They need a Japanese researcher as the main researcher. I remember Ryugo Oshima. It has been a while since I keep in touch with him. He is definitely below 45 years old. I should message him on FB ASAP. But he is not into qualitative research. Perhaps I should ask if he can recommend someone who he knows doing related research as what the Toyota Foundation requires.
HERE is the link to the website.
The deadline for the grant application is on middle of September 2019.
