On December 3rd, AKB48 sub-unit Watarirouka Hashiritai 7 held their release commemoration event for their latest single, �Kibou Sanmyaku�, at Yomiuri Land in Inagi, Tokyo.

Although it was raining, all 7 girls made a lively appearance in red and white Santa dresses. The energy on set got an additional boost thanks to a cameo from Crayon Shin-chan himself, whose animated series will be using "Kibou Sanmyaku" as its theme song.

Member Watanabe Mayu (17) commented, �Although it rained, we had so much fun that the rain eventually blew away." The girls also mentioned their upcoming appearance on Kohaku Uta Gassen, and they expressed, �We will do our best to perform in front of large crowd.�
