National sport of Japan (4)

I believe the answer is:

sumo

'national sport of japan' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for sumo that I've seen before include "Jap. wrestling" , "Style of traditional Japanese wrestling" , "Grappling" , "Large Japanese wrestler" , "Kind of wrestling" .)

I've seen this clue in the Universal, the USA Today and the Newsday.com.
