Girls' Generation continued their success in Japan with the single "Mr. Taxi / Run Devil Run", released in April 2011. The single peaked at number two on the Oricon Singles Chart and as of April 2017, was certified Million by the RIAJ. After releasing three singles in Japan, their debut eponymous Japanese studio album was released in June 2011. To promote the album, Girls' Generation embarked on The 1st Japan Arena Tour, which started in Osaka on May 31, 2011 until July 18. The group subsequently followed up the success of their Japan tour by embarking on their eponymously titled third tour, the Girls' Generation Tour, starting just a few days later on July 23 and had the group perform in Singapore for the first time.
