It's not unusual in Japan or Malaysia (6)
I believe the answer is:
normal
'it's not unusual' is the definition.
(I've seen this before)
'in japan or malaysia' is the wordplay.
'in' says the answer is hidden in the clue.
'NORMAL' is hidden in the letters of 'japan or malaysia'.
(Other definitions for normal that I've seen before include "Usual, typical, expected" , "Popular" , "Customary" , "Standard; at right angles" , "Unexceptional" .)
