I just happened to find it. If there is anybody who wants to learn Japanese in a proper course.

Thank you for your additional information, Wei. I'm sure it helps others.
Anyway, I'm interested in Taiwanese writing and reading. I don't have enough time to spare for that at the moment, though...
Thank you for the information, Yuko! It looks awesome.
I went to the link. For those of you interested, it's a FREE online course (5 weeks, 3 hours per week) on Japanese pronunciation and communication provided by Waseda University, which to my knowledge is a top-notch Japanese University, kind of like a Japanese Ivy League. It starts on Nov. 6; I'm not sure if you have to watch it live or if you can watch it later as a recording. You need to know basic Japanese and know how to read Hiragana and Katakana.
