Could I be a Firefighter in Japan as a foreigner

I want to move to japan but I also want to be a firefighter more than anything, so if this isnt possible i probably won’t try to move to Japan. I dont want to live in tokyo or any of the main areas because theyre expensive and have a higher population, im looking more at areas like okinawa and nagasaki, but i do know there is a slight racism in Japn, ive heard. Such as how theres Japan only restaurants, but im okay with that stuff, but is there also racism in getting jobs? My race is puertorican+american if that changes anything
