Who is this main warrior figure or warrior founder of Shinto?

There isn't. That's why I called it "the closest religious thing."

OK Thanks. I thought by "closest thing" to Islam you meant the warrior ethos in Shinto.

Shinto almost died out as a viable religion but in the seventeenth century it was revitalized by tough-minded military leaders. A combination of Shinto and Confucianism was used to develop the warrior code of Bushido.
