Japanese is the Spanish of Taiwan. Relative to the USA, I mean. Japanese here functions like Spanish in many parts of the USA. A lot of people know a little bit of the languages. Their cultures form a large part of the respective culinary customs. Many people feel an inchoate interest or sense of urgency to learn more of them or to visit a native country of that language. Both languages are seen as (somehow) "important these days." Even those who do want to learn them are intimidated by the difficulty of the grammar (compared to their mother tongue).
Oh, and I'm learning both of them with a serious interest to move to Japan.
