Some of the best Japanese bboys, streetdancers, breakdancers gather in front of the OCAT building of JR Namba station in Osaka.
In October, an international competition called B1 Saikyo Tag (B1最強タッグ) was held there. It gathered contestants from all around the world as well as the best Japanese dancers.
Here is a little long, but worth watching video of a battle held on the evening before the main contest. Recorded on Oct. 8th, 2011. Enjoy!
