Hideaki Takizawa, also known as Tackey of Tackey & Tsubasa, released his first solo single last week, titled "Ai Kakumei." The song led the charts at 57,000 copies, making him the first member of a group to reach #1 with a debut solo single since Koichi Domoto did it in 2006.

At #2 was Junko Akimoto, still riding a wave of renewed interest after Kohaku Uta Gassen. Her "Ai no Mama de," originally released last January, continued its ascent for the second week in a row. Mihara also saw her album "Second Story" jump from #54 to #23 this past week. Released in August, it debuted at #90 and quickly fell off the charts, but it resurfaced at #67 about a month ago.

New singles from Remioromen, The Possible, and Base Ball Bear entered the rankings at #3 to #5.

On the album charts, EXILE and Mr.Children regained their top spots, taking #1 and #2 to bump Ikimono Gakari down to #3. In terms of new releases, indie band SOUTAISEIRIRON made #7 with their first full album, while Base Ball Bear picked up #10.
