I have no personal experience of working in Taiwan, but anecdotally, it has a Japan-esque work culture. Full-time employment at a traditionally managed Japanese company -- i.e. being a salaryman -- is, largely, not an experience I would recommend to someone I loved. There exist some startups or e.g. foreign-owned firms which would be far less odious options.

Living in Japan is wonderful. A++ would totally immigrate again. A substantial portion of my present happiness is having created a job which means that I am 99.8% insulated from Japanese megacorps.
