Japanese cartoon featuring in seminars from the east (5)
I believe the answer is:
anime
'japanese cartoon' is the definition.
(Japanese animated film)
'in seminars from the east' is the wordplay.
'in' indicates a hidden word.
'from the east' is a reversal indicator.
'emina' is hidden within 'seminars'.
'emina' back-to-front is 'ANIME'.
'featuring' is the link.
(Other definitions for anime that I've seen before include "Japanese cartoon style" , "Drawing style" , "style of Japanese film" , "Japanese cartoon film genre" .)
