This is not the first time AKB48 has performed a medley in Kouhaku Uta Gassen. Their first appearance in the 58th Kouhaku Uta Gassen, they performed Aitakatta and Nantetatte Idol together with artists Shokotan and Leah Dizon. Then on the 60th Kohaku Uta Gassen they performed RIVER Surprise Kohaku Remix, a medley of RIVER and Namida Surprise.
This year's Kohaku seems to be an AKB48 special. There will be tonnes of appearances by AKB during the whole duration of the show, not just their segment. They will be appearing in other artist's segments, including backdancing to Arashi's Bokutachi no Furusato Nippon, and a collab with Mizuki Nana singing an anime song. Members will also be doing backstage reports. The full list after the jump. The show will start on 7:30PM on 31 December 2010 and will run until 11:45PM.
