You may know these kanji are called "common use kanjis(常用漢字 Joyo-kanji)".
We remember this for nine years, but i think it is hard for foreigners to
remember these in a short time after becoming an adult.
After all, the easiest way to remember them might be watching anime and manga.
I also study English watching Hollywood movies.
However, recently, the number of foreigners who understand Japanese
is increasing dramatically and I am really surprised.
