Time has issued its best of Asia issue and the Nomad notes that it suggests Seoul offers the best location to be nude.:

When you do it for the first time, you stand there for mere seconds, thinking “I can’t believe this,” before scurrying for the cover of your fashionably minimalist bedroom. The second time, you force yourself to linger a little longer and at least take in the view. But well before your stay at the Park Hyatt is over, you have accustomed yourself to standing naked in a bathroom that comprises nothing but glass on three sides, situated above one of the busiest intersections of one of the busiest cities of the busiest continent on earth. Sustaining it all is the questionably held faith that the thin panes in front of you really are reflective.

Also curious, the list suggests Lahore in Islamic Pakistan as the locale for the best experience in a red-light district and megacity Tokyo as having the best fishing hole.
As such, it’s not so much of an objective attempt at naming the ‘best’ as it is a fluffy — albeit enjoyable — filler issue. In that vein, AP would welcome other suggestions for the ‘best’ in Asia. Surely readers are no less informed than the writers for time (although you will be unpaid).
