When we were kids, the Buddhist Temple showed Japanese movies in the auditorium, and we used to sneak in by the windows. What's interesting to me is that we used to talk to our mother in Japanese, and I even attended Japanese school for three years as a young teen, but lost most of my ability to speak it when our mother passed away in the early 80's.
When my wife and I visited Japan in the early 80's, the little I could read Japanese was really helpful. Even after these many years, I can still understand the jest of the story of Japanese movies.
I can still write a little of the Chinese calligraphy, and read the two alphabets (51 in each) in the Japanese language.
