The research proposal by assistant professor Kashiwa has been granted the ‘Strategy of SAKIGAKE’ (https://www.jst.go.jp/kisoken/presto/en/index.html) fund by the Japan Science and Technology Agency. The funding for the ‘Strategy of SAKIGAKE’ was established under the Strategic Basic Research Programs set up by the Japanese government. As many researchers submit research proposals but only a very small number are accepted, obtaining this funding is known as a gateway to success for young researchers.
