The Japanese Summer Festival will be held at 10 Feb 2013 at New Quay Piazza, Docklands. I've been there last year and really enjoyed the Bon Ordori group dancing. Many things and people with traditional kimono to photograph.
Melway: 2E D4
Trams: City Circle Tram 35 – Stop Harbour Esp.
Tram 70 / 86 to Waterfront City Docklands – Last Stop
I've also included the information about the festival in the URL.
