SECRET is making their comeback in full force.

The girl group, who will be making their official return this August, successfully completed their solo concert in Japan.

The four-member girl group held their "2014 Secret's Summer LIVE YooHoo" solo concert and gained the attention of both fans and local media in Japan. Secret's third solo concert was held in both Tokyo and Osaka, with the girls providing four performances in total.

The members of SECRET got fans wild as they performed their hit songs, including "Shy Boy," "Madonna," "TWINKLE TWINKLE" and more. Jun Hyoseoung, Jung Hana, Song Jieun and Han Sunhwa also held solo and duet stages throughout the course of their performances, promoting each member's individual projects in Japan.

SECRET thanks fans via Twitter for making it out to their concert and showing their ongoing support.

The success of their recent hit "Yoohoo" has led to the release of a Japanese version of their music video. For the recently released version, the girls showcased a highly different concept from their original Korean music video by giving fans a snippet of their time at a luxurious hotel.

"Yoohoo" was produced by popular K-pop producing team Duble Sidekick. The idol members recently made headlines when they decided to stray from their usual composing team, Kang Ji Won and Kim Ki Bum, according to Allkpop.

SECRET has been known for their swift concept transformations throughout the course of their career.

"Originally debuting with an urban R&B concept, the girls of SECRET have transformed themselves into the queens of retro ever since their breakthrough hits with 'Magic' and 'Madonna.' Furthermore, with Wonder Girls recently vacationing their long-held affair with retro in favor of a more fresh and futuristic approach, SECRET lays claim as the next best group to have established a retro identity," wrote the publication Seoulbeats.

Park Hyunmin of enewsWorld added that "SECRET's main appeal is its retro beat and sexy choreography."
