Killer skirts from Nagoya enthralling fashionable Japan (5)
I believe the answer is:
ninja
'killer' is the definition.
(I've seen this before)
'skirts from nagoya enthralling fashionable japan' is the wordplay.
'skirts from' suggests removing the centre.
'enthralling' is an insertion indicator.
'fashionable' becomes 'in' (in can mean fashionable or trendy).
'japan' becomes 'j'.
'nagoya' with its middle taken out is 'na'.
'in'+'j'='inj'
'na' going around 'inj' is 'NINJA'.
(Other definitions for ninja that I've seen before include "Feudal assassin" , "old mercenary" , "martial art expert" , "Killer" , "Japanese mercenary warrior" .)
