"Ultra Music Power," the first single by new Johnny's unit Hey! Say! JUMP, sold 247,000 copies this past week, putting it at the top of the singles chart. This makes them the 13th artist to enter the charts at #1 with a debut single. This was last achieved in early 2006 by KAT-TUN with "Real Face."

On the albums chart, fellow Johnny's group KinKi Kids also claimed the #1 spot, selling 190,000 copies of their new album "Phi." With this, 12 of their 13 albums (including their 3 best albums) have been chart-toppers.

Meanwhile, voice actress Nana Mizuki's album "GREAT ACTIVITY" came in at #2 with 43,000 copies sold. This is the highest sales ranking ever for an album released by a seiyu. Mizuki also holds a similar record for singles released by a seiyu, having reached #2 with "SECRET AMBITION" earlier this year.
