Popular duo KinKi Kids extended a world record this week with their 28th single, "Yakusoku." 171,000 units of the CD were sold in its first week, propelling it to #1 on the charts. This further cements their Guinness World Record of having the most consecutive number-one singles starting with the artist's debut. They also have improved their Oricon record of most consecutive years with a number-one single (13).

GReeeeN ranked in at #2, selling 72,000 copies of their new single, "Ayumi." While Junko Akimoto remained on the charts at #3, the rest of the top ten were all new releases: Kazuya Yoshii, Kaela Kimura, Gackt, Miliyah Kato, MUCC, Yui Horie, and Watarirouka Hashiritai.

On the albums chart, Kumi Koda emerged victorious with 253,000 in sales for her seventh release, "TRICK." It is her third consecutive original album to top the charts.

Trailing far behind Koda was Miho Fukuhara at #2 with 45,000 in sales. TERIYAKI BOYZ managed #3 with "Serious Japanese," which is scheduled to get a U.S. release next month. Kiyoharu (#5) and FLOW (#7) also entered the top ten with their new albums.
