My bolding.
Bullshit. Your statements are categorically false.
First, you are completely wrong about Koreans not qualifying for citizenship. They are, and many do. Others do not for various reasons, but it is not because they are restricted from doing so. This is a site to fight ignorance. Please do not spread it.
Certainly, there is discrimination by many in Japan against other races, particularly non-white foreigners. Many people do not like Koreans and many Zainichi Koreans have suffered from discrimination, some small and some large.
However, you cannot say that they are held to be a lower form of life by Japanese in general. That is completely false.
After Japan took Korea as a colony, one thing they did was to force assimilation, making Koreans take Japan names and speak Japanese. While they discriminated against them, they did not consider them "lower forms of life.
Discrimination against Koreans and other foreigners is lessening over time. What was acceptable 75 years ago is no longer the case. You cannot use false information to support a racist rant.
There was a lot of ugliness about what happened in the war, and the horrible things the Japanese did. There is no mistake about it.
However, by employing easily disproven absurdities, it detracts from any legitimacy in the argument.
Again, bullshit. You stated something which is false and when called on it then you are trying to muddy the water.
From your own cite:
Zainichi Koreans are allowed to become citizens.
Again, yes there was discrimination in the past. There still is some today, but it’s lessening and it is not how you are characterizing it.
