I've now reached an area of Lonsdale (near Swanston) which is apparently very popular with Japanese tour groups.

How do I know?

Well, lemmie see... there are the small Japanese figurines that appear behind the display of glasses in this optometry practice.

There's the fact that a description of the services offered appears in Japanese on the practice window.

But the big give-away? Just a few metres along from this practice I saw three coach loads of Japanese tourists standing across the footpath waiting for their tour buses to depart.

Elementary, my dear Watson.
