Join the Babymetal revolution!

Babymetal started their 2015 right playing a sold-out show for 20,000 fans inside the arena.

The group performed songs like "Gimme Chocolate," "Megitsune" and "Iine!" that have all seen their videos go viral on YouTube.

Fans were more than willing to dance along with Babymetal's kawaii choreography.

A little fog, anyone?

Boasting a huge production values, the stage setup resembled an epic castle complete with columns and drawbridges. 

Babymetal perform with their backing band KAMI BAND (Gods of Metal Band) who are freaky looking...but also freakishly talented.

Thousands of screaming fans (mostly male) eager to cheer on Babymetal's biggest concert to date.

In the non-stop show, a costume change meant throwing on these skeleton hoodies over their cutesy, gothic dresses.
