Japanese port to get a soak tipsy (5)
I believe the answer is:
osaka
'japanese port' is the definition.
(I've seen this before)
'get a soak tipsy' is the wordplay.
'get' means one lot of letters go next to another.
'tipsy' indicates anagramming the letters.
'a' put next to 'soak' is 'asoak'.
'asoak' is an anagram of 'OSAKA'.
'to' acts as a link.
(Other definitions for osaka that I've seen before include "Japanese port, on Honshu" , "Port city on Honshu, Japan" , "Major port and commercial and industrial centre on Honshu" , "S. Japan port, bay" , "Place" .)
