Dancer is twice as game in Japan (2-2)
I believe the answer is:
go-go
'dancer is twice' is the definition.
I know nothing about this answer so I can't judge whether this works.
'game in japan' is the wordplay.
I cannot quite understand how this works, but
'game' could be 'go' (go is a board game) and 'go' is found within the answer.
The remaining letters 'go' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'as' is the link.
Can you help me to learn more?
(Other definitions for go-go that I've seen before include "Kind of erotic dancing" , "__________ dancer, exotic performer" , "Type of erotic dancing" , "Assertively dynamic" .)
