Pop group, Keyakizaka46 have stirred controversy online after their Halloween costumes were compared to Nazi uniforms.

The Japanese girl idol group wore military-style costumes when they performed at Yokohama arena in Japan on Saturday.

Their show was called ‘Perfect Halloween 2016’ with the group of girls (aged 15 – 21) dressed in black one-piece military-style dresses, a cape and a peaked hat. Since their performance, social media has been abuzz with backlash.

The group formed in August 2015 – as a sister group to Nogizaka46. Their first single was Silent Majority, which made it to number one on the Billboard Japan Top Singles Sales chart - proving that the girl group is popular.

But their costumes weren’t so popular this weekend. The backlash has been picked up by many online publications.

The band has not made any comment about their costume, with some taking to social media to suggest the clothing choice was solely a publicity stunt.

The group was produced by well-known Japanese record producer, Yasushi Akimoto.
