5 member idol group B1A4 have topped Japan’s Tower Records Chart.

On January 20th, B1A4’s fifth single, Shiroi Kiseki, topped the reservations portion of the Tower Records Chart.

According to reports, this showed that all of B1A4’s single packages had topped the cumulative charts and not just the K-Pop charts, proving their popularity in Japan.

Tower Records is a ranking site for Japanese albums and videos.

Their title song, “Shiroi Kiseki,” was a self-composed song by leader Jinyoung and was created for their Japan fans.

On the other hand, their teaser video for the title song has been released online.

This single will be released in three different editions on January 21st.

There will be limited editions as well as regular first press editions. These two types will come with either an individual member autograph session, gift lottery or high-touch event.

Their previous Japanese single, Solo Day, was released last September.
