"It's all Love!," the collaborative single between Kumi Koda and misono, topped the charts this past week with over 74,000 in sales. Ever since Oricon launched its weekly sales rankings in 1968, this is the first time that a group composed of actual siblings has taken the #1 spot in its initial week.

Counting singles that reached #1 after the first week, the Koda sisters are the 4th sibling group to accomplish this feat. The first was the male duo Billy Banban in 1972, followed twice by The Finger Five (4 brothers and 1 sister) in 1973 and 1974, and then the Irish sisters The Nolans in 1980.

Kumi Koda is no stranger to the #1 ranking, but misono had never before reached higher than #2 since the start of her career as part of the band day after tomorrow.

The AKB Idoling!!! collaboration ranked #2 on the singles chart, followed in order by Mai Kuraki and Kaori Mizumori. Masayoshi Yamazaki also entered the top ten with a new song at #9.

On the album rankings, Dreams Come True's "DO YOU DREAMS COME TRUE?" regained the #1 seat, after being temporarily ousted last week by Ayumi Hamasaki. The album has now reached the milestone of 1 million units shipped.

The only new release in the top ten albums was "PB" by SPECIAL OTHERS, which landed at #10. Meanwhile, Ayaka's second album "Sing to the Sky" (released last June) jumped up from #278 to #84, apparently fueled by last week's announcement of her marriage to actor Hiro Mizushima and her impending hiatus due to Graves' disease.

Hikaru Utada's second English album, "This Is The One," held onto the #1 spot on the foreign albums chart for the third consecutive week.
