Why would they hate her for having Korean ancestry?
Typically, Japanese people are kind and generous, and they will closely look at the person's attitudes. The people who are not liked are the people who hate Japan and the Japanese people.
As an example, people who graduated from the Korean School (Chousengakkou) will be given an Anti-Japanese education. I heard from a Korean background person that at a Korean School, if you speak Japanese at the school, you will be beaten by your mates.
Few years ago, there were K-POP trend in Japan, and people were very interested in Korean culture and the Korean people. But when they start knowing that the majority of Korean people have huge hatred towards Japan and also the Japanese people, now many Japanese people are becoming suspicious when they hear the word Korea. It is not because they are racist or not. It is just a rule of thumb or statistics.
Koreans do remember the times when Japanese teachers would beat up Korean boys at school for using Korean, force Koreans to adopt Japanese-style names, and send young Koreans to the Pacific to be slaughtered, for the glory of Emperor Hirohito.
Personally, all the Japanese I met were nice people, and I normally don't talk history with them (I mean, what's the point?), because there are more pleasant stuff to talk about. Hopefully many others in Japan would also meet some Koreans some day and realize we are all the same people, with different historical baggages, trying to make sense in a world that doesn't make sense.
But then there are always some jerks who would say "Koreans are so mean, why do they hate Japan so much?"
Well, duh.
It takes different forms in different countries, but it is alive and well.
Does it help in anything?
If there are 10 people at a table about to starve to death, and only 5 of them are related, it helps their genetic lineage to prefer to feed relatives.
Racism, as an outgrowth of us-versus-them, most likely helped with keeping a lineage alive.
Many argue that an arbitrary division among the disenfranchised and poor is an effective barrier for them to rise up against the minority that hoard the resources for themselves. So one could argue that it does help someone.
Considering that racism is quite impractical.

I don't think it would be very hard to find places that are a lot more racist that Japan. (Not that you'd want to go there…)
We can only hope that these chains loosen over time as people reject the prejudicial treatment of others.
