I found this while searching the web this morning. It appears to be a nearly comprehensive (gasp!) listing of martial arts organizations here in Taiwan. Of course, Chinese martial arts are most predominant but it also lists karate organizations, kendo, aikido, etc. as well.
The list is even divided into styles, at least roughly. The names of teachers, phone numbers, and addresses are all included. This is the most organized list of this type I have ever seen here so I thought others might find it useful.
