I started learning Japanese a few years ago. I can read and write Hiragana and Katakana to some extent and also a very little Kanji. Actually, I found it very interesting, but Japanese is a difficult language to learn for a speaker of a germanic language. :-) I also discovered that the Japanese unashamedly pinched the chinese characters about 400 years ago - before that they had no writing. But that they were willing and able to leverage this discovery for themselves demonstrates what you said.
Incidentally, I discovered you can't learn a foreign language without learning about the culture. It changed my views of East Asia forever.
