How about Zhunan in the North West area of Taiwan?
The wind funnels between China and Taiwan, so it gets fairly consistent strong winds. Mainly 7's and 9's used.
Unlike most kite spots in Asia this one is super-easy to get to. Fly into Taipei, and take about a one hour transfer.
Small waves, choppy water (but at certain tide levels it flattens out), and there is a river mouth nearby if you want to play in flat water.
The beach is long and wide, but the sand is fairly dark in colour and the water is murky due to the churning of the sand.
We always stay at 'Spot' beach club. It's a beach shack with cheap dormitory style accommodation, but it's comfortable and a usually there's a good crew hanging out. They sell beer, soft drinks, and water, and some limited food. There is no kite shop there, so bring everything you think you will need. The last trip I stayed 3 nights, including all soft drinks (To add to my Bourbon), and one breakfast, totalled 2600 NT (USD $82) Transfers were 1500 NT each way (USD $47). It's pretty common for some of the regulars to do downwinders too.
