How long is the flight from thailand to japan,?

Question

more specifically, Utapao to Hiroshima

Answer 1

A non-stop flight from Bangkok to Tokyo is typically 6 hrs. on a commercial airline. Unless you have a private plane, there are no flights to Japan from Utapao, even from Bangkok there are no non-stops to Hiroshima. So it's hard to answer your question unless you say you are flying a private plane or whether you'll depart from Bangkok and connect in any number of different cities in Asia.
