Traveller abroad very keen on Japanese theatre (5)
I believe the answer is:
nomad
'traveller' is the definition.
(nomad is a kind of traveller)
'abroad very keen on japanese theatre' is the wordplay.
I cannot quite see how this works, but
'keen' could be 'mad' (both can mean enthusiastic about) and 'mad' is located in the answer.
The remaining letters 'no' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nomad that I've seen before include "drifter" , "One travels from place to place with no permanent home" , "Member of travelling people" , "Member of a wandering pastoral community" , "Unsettled character" .)
