Drama in Japan about southern food (4)
I believe the answer is:
nosh
'food' is the definition.
(nosh is a kind of food)
'drama in japan about southern' is the wordplay.
'drama in japan' becomes 'noh' (I've seen this before).
'about' indicates putting letters inside.
'southern' becomes 's' (abbreviation).
'noh' placed around 's' is 'NOSH'.
(Other definitions for nosh that I've seen before include "Scoff" , "Eat (sl.)" , "Food (coll)" , "eating this?" , "Slangy food or meal" .)
