Tokyo Game Show (TGS), Japan's biggest gaming event which began at Chiba's Makuhari Messe convention center on Thursday, will continue through Sept. 18.

The show, which seemed impossible after the Great East Japan Earthquake on March 11, has drawn more than 140 exhibitors, with offsite parties happening late at night.

The Japanese game developers are now looking forward to ward off the threat that has arrived in the form of other big game developing names like EA and Activision.

Listening to the government's decision on setseuden (power consumption), the organizers have implemented measures like turning off escalators, using LED bulbs and limiting power for exhibition booths to reduce energy consumption.

Previously, the TGS had seen the arrival of the next-generation PS Vita. Now, there are around 40 PS Vita games on display with nearly 80 PS Vita demonstration kiosks for visitors to check out the new hand-held gaming device.

Here is a look at the TGS 2011.
