Trained assassin from town in Japan (5)

I believe the answer is:

ninja

'trained assassin' is the definition.
(I've seen this before)

'from town in japan' is the wordplay.
'from' indicates the answer is hidden within the clue.
'NINJA' can be found hidden inside 'town in japan'.

(Other definitions for ninja that I've seen before include "Assassin from Japan" , "Japanese mercenary warrior" , "Mercenary in feudal Japan" , "Animated turtle" , "Assassins" .)

I've seen this clue in The Telegraph.
