The Japanese art of fencing (5)
I believe the answer is:
kendo
'the japanese art of fencing' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for kendo that I've seen before include "Marrtial art" , "Japanese martial art using split bamboo swords" , "discipline" , "Japanese art of fencing with staves" , "Japanese fencing with bamboo staves" .)
