Artist born in Japan - or thereabouts (3)
I believe the answer is:
ono
I believe this clue is a double definition.
'artist born in japan' is the first definition.
(Yoko Ono)
'thereabouts' is the second definition.
(short for 'or nearest offer' in sales listings)
'or' acts as a link.
(Other definitions for ono that I've seen before include "Or nearest offer (abbr.)" , "Yoko ..., wife of John Lennon" , "Singer's wife" .)
