Port on Osaka Bay (4)
I believe the answer is:
'port on osaka bay' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kobe that I've seen before include "Japanese port, hit by an earthquake in 1995" , "Japanese 1995 earthquake site; be OK (anag.)" , "Eastern port" , "City in Japan" .)
