Round Japanese train? (6)
I believe the answer is:
bullet
This could be a double definition.
'round japanese' is the first definition.
'bullet' can be an answer for 'round' (thesaurus). I am unsure of the 'japanese' bit.
'train?' is the second definition.
(I know that bullet is a type of passenger train)
Can you help me to learn more?
(Other definitions for bullet that I've seen before include "Piece of ammunition" , "Have attraction" , "Projectile ammunition" , "Point in report" , "Revolver missile" .)
