A longing for Japanese money (3)
I believe the answer is:
yen
'a longing for japanese money' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for yen that I've seen before include "Itch, craving" , "Unit of money in Japan" , "Have a longing for Japanese money?" , "Itch, desire" , "Japenese currency" .)
