(Osen)

Four-member girl group f(x) completed concerts at Ariake Coliseum in Tokyo on Saturday and Sunday.

In the concert titled “f(x) the 1st concert Dimension 4 - Docking Station in Japan,” the group tried out new versions of their songs “Hot Summer” and “4 Walls” with Japanese lyrics, doing 35 total songs.

F(x) will continue their performances at Fukuoka, Osaka and Nagoya from Tuesday.

They first held a Japanese concert in the year of their debut in 2009, but it took seven years for them to return.

The group recently staged their first solo concert in Seoul in the end of January.
