It's not easy to pick 10 places in Asia ( I can do 1, no problem - anywhere east of the Urals

) but here goes, with some rather broad areas :-
1.
Sabah ( includes Gng. Kinabalu, Danum etc. )
2.
Hokkaido, Japan. ( includes Shiritoko peninsula, Kushiro marsh, Daisetsu Mts. etc. )
3.
Nansei Shoto, Japan ( includes Amami, Okinawa, Iriomote-jima etc. )
4.
Vietnam. ( too many superb places to mention individually ).
5.
Tibet ( ditto ).
6.
Sumatra ( anywhere ( that hasn't been trashed ) in Bukit Barisan )
7.
Nepal ( ditto Tibet / Vietnam )
8.
Sichuan, China. ( just for the 'shed-load' of endemic species alone )
9.
Taiwan.
10.
Tuva. ( Partly because it's a bu**er of a place to get to but also the wildlife and scenery are unbelievable. )
I've just hammered these out as I kept thinking of other places that could, quite easily, be fitted in. I'll probably change my mind on a few in the next 5 minutes, but these will do - for now.
