Does walk, say, regularly, in Japanese city (5)
I believe the answer is:
osaka
'japanese city' is the definition.
(I've seen this before)
'does walk say regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'does'+'walk'+'say'='doeswalksay'
The alternate letters of 'doeswalksay' are 'OSAKA'.
'in' is the link.
(Other definitions for osaka that I've seen before include "Place" , "Port city on Honshu, Japan" , "Kinki's capital" , "Third most populous Japanese city" , "Japanese port city" .)
