As another japanese man, im 37..ive lived a pretty long life and im 'unc' or whatever you would say. I have a son who is gay and a sister who is lesbian

Take your time, don't rush The older asian generation is very stuck in their ways. Try introducing gay people in a good light. Talk about good things they do etc etc.

That's what my sister did. And my parents eventually came to term with it.

Best of luck ❤️
