When the topic arose, IU swiftly signed the contract and was determined to participate in the project. She described it as a great opportunity for her to gain experience as a girl group member, and add new titles to her collection. The girl group gained success in Japan, where the concerts \"Girls Generation Japan 2012 Tour\" and \"Girls' Generation World Tour\", held at the NHK Hall, Daioh, and the Kobe World Memorial Hall respectively, were extremely successful. The concert was also historic, as it was the first time in the history of the Japanese concert industry that a girl group was invited to play in the NHK Hall. For their performance, they performed a costume change, a dance change, and a special stage performance. In October 2012, SNSD held a press conference at Shinagawa Prince Hotel, where they announced their plan to release a Japanese-language single with the same title.
On February 22, 2013, Billboard reported that N's Ark, an アートトランスのミュージックステージ Limited Edition boxed set that N would release on March 25, 2013, at a cost of 1,299 dollars. The box set contained a Blu-ray picture disk, and a DVD of the live album that N's Ark will release. The live album, which follows the same concept as the live DVD of Band-Maid, is a live recording of the girl group's concert tour in Japan. The live was recorded at Humac Town Hall, Kobe in February 2012, and was released on May 17, 2013. 7211a4ac4a
