Why do you want to tell me the participating countries of jsf project in Japan?

Japan participates in the lowest of the four different stages of R&D, and belongs to the same group as Singapore and Israel, and is mainly responsible for funding and providing technical information. Japan only participated in R&D affairs in the medium term. Japan hopes to introduce production lines when purchasing F35, so as to improve the level of its aviation industry. Therefore, the Japanese government has been negotiating with the US government to manufacture some parts in Japan.
