Mows walkway regularly in this city (5)
I believe the answer is:
osaka
'this city' is the definition.
(Japanese city)
'mows walkway regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'mows'+'walkway'='mowswalkway'
The alternating letters of 'mowswalkway' are 'OSAKA'.
'in' is the link.
(Other definitions for osaka that I've seen before include "Large city and port in Japan" , "Place" , "Kinki's capital" , "Japanese metropolis" , "Japanese city near Kobe" .)
