Popular girl group f(x) is preparing to officially release their popular song "Hot Summer," that received much love last summer, in Japan this summer in preparation to the group's Japanese debut.

The Japanese version of "Hot Summer" was first revealed as it has already been selected as the commercial background song for Uminoie Resort, giving fans in Japan a sneak peek to the catchy tune.

As the song is to be distributed for free before f(x) makes their official debut, it's expected to significantly boost the group's awareness in Japan before they begin subsequent promotional activities.

The song is garnering a lot of expectations for the response in Japan as the song received much love last summer in Korea.

Currently f(x) is focusing on individual activities and gearing up in preparations for their Japanese debut after concluding promotions for Electric Shock.
