Rookie girl group Crayon Pop has sold out their upcoming Japanese mini-concert.

Crayon Pop debuted in Japan prior to promoting in Korea and they’ve been very successful in the country, clinching two major endorsement deals with cosmetic and beverage brands. Continuing with their successful run, the group will be holding ‘Crayon Pop 2013 New Year Mini Concert’ in January.

This is the first concert for Crayon Pop in Japan and will be a part of their upcoming Japanese promotions. It took the rookies less than one hour to sell out all the seats for their concert as soon as the tickets went on sale.

Crayon Pop’s agency, Chrome Entertainment stated, “We were both surprised and thankful for all the support the fans have shown us. We’re planning on holding additional concert filled with fun stages, honest talk segment and Crayon Pop’s various charms.”
