Will Japanese People accept me if I integrate well ?

I have signed a contract with a Japanese company, I would be moving there in April 2028, until then I am being taught Japanese language and culture. So, if I speak the language well, respected their culture would I still have to face racism (even subtle ones). I am from South Asia, and our people are disliked all over the world and even more in Japan. I don't want to be in a bubble of just my own countrymen in Japan (which there are a lot of), I want to integrate to the society and live as any normal Japanese will live their life and have Japanese friends
