It is held in Australia, Broome. (see http://www.shinjumatsuri.com/).
Broome's Festival of the Pearl, Shinju Matsuri, began over 35 years ago.

Handing out the meal.
The pearling industry thrived here, with up to 400 luggers fishing off the local shores. People from Japan, China, Malaysia and elsewhere were brought in to work the boats and dive for pearl shells. When the pearl harvests would finish, the traditional cultural festivities and celebrations would begin.
With the release of the film Shinju we will soon be celebrating the 'Festival of the Pearl' ourselves ;o)
NOTE: Shinju (from the Japanese 真珠 meaning pearl).
