Most people in the expat community I know went to Hong Kong and Singapore instead for the following reasons: 1) Easy to do business 2) Easy to get your money in and out. 3) Low taxes 4) Central travel hubs in Asia 5) Less backwards mindset as these cities feel more cosmopolitan and are interconnected with the outside world
With HK having less and less freedom, Singapore is really the only choice for foreigners to have a decent life quality in Asia. Tokyo could potentially be an option too, but it's really hard to live there due the very different structures in Japanese society and taxes are pretty high.
