Japanese verse originally hidden away in Kyoto university (5)
I believe the answer is:
haiku
'japanese verse' is the definition.
(I've seen this before)
'originally hidden away in kyoto university' is the wordplay.
'originally' suggests taking the first letters.
'university' becomes 'u' (abbreviation for university).
The initial letters of 'hidden away in kyoto' is 'haik'.
'haik'+'u'='HAIKU'
(Other definitions for haiku that I've seen before include "Seventeen-syllable Japanese poem" , "Japanese poem of seventeen syllables comprising three lines" , "Jap 17-syllable poem" , "Type of Japanese poem" , "ode" .)
