In the concert picture (above) that was released on January 9th, Psy can be seen singing and dancing in front of a giant, inflatable, mechanical doll of his likeness. This prop had been also used before in Psy's performance of 'One Touch" last month. 

During the performance, the mechanical doll moved in a humorous manner, alternating smoking and drinking with his arms. The doll even manages to strip in the middle of the performance, making it more memorable. It's not surprising that Psy took the doll all the way to Japan to show it off.

The doll was not the only notable aspect of Psy's performance. He also dazzled and impressed the audience with his powerful vocals and choreography. His florescent costume also helped. 

'YG Family Concert' will also be held in Saitama on January 21st and 22nd.
