Notice his last name is Korean? But he was born and raised in Japan.
And here's what he has to say: https://asia.nikkei.com/NAR/Articles/SoftBank-s-Son-stands-u...
Even in his early childhood, he was attacked verbally and physically by Japanese classmates. In kindergarten, he was jeered at for being Korean. Once, another child cut his head open with a stone.
After WW2, there was over 1 million Koreans living in Japan. Some went back, some decided to wait due to the war starting.
Then the country they were going back to no longer existed, so they stayed. Many don't even have citizenship.

I also remember hearing about how Pachinko parlours are usually owned by Yakuza/Zainichi and they funnel profits into North Korea.
It is a minority. And Japan is very racist towards them. Turns out there are 3 kids in that situation in my family.
We already witnessed three classes having racist bullying and both teachers and school direction refusing to do anything.
I do believe that this mentality of blaming the victims that do not "fit in the mold" is indicative of a very negative culture.
I think coming out to the internet, sharing some personal anecdotes about racism and personal issues, and maybe publishing problems you've experienced personally can help. Not only for teaching others about the issues you yourself face, but also for helping keep ones emotions in check and meditating upon your own issues.
Obviously, this discussion thread exists to criticize Japan and bring forth issues. But in order to be more helpful to everyone involved, its more beneficial to be more specific about what can, and can't, be done to fix certain issues.
With regards to your specific point: giving up because of cultural norms is defeatist and doesn't seem helpful in any case. Now I'm not Japanese, nor have I ever been to that country. But it sounds like Japan is a functioning democracy, so publishing opinions and raising issues is definitely the way to move forward in that kind of political system. The people must be aware of a problem (and agree that it is a problem) before you can ever hope for the politics to change.
Or Zainichi Koreans, who are born and raised in Japan (there are a LOT).
