After the conclusion of the Babymetal World Tour 2016: Legend Metal Resistance, the band supported Red Hot Chili Peppers, Metallica, Guns N' Roses, and Korn on their world tours as an opening act for several of their shows.

[13] During the tour, the band also took part in Summer Sonic Festival in Osaka and Tokyo on August 19 and 20, respectively.

[14] When asked for the reason for starting the tour, Su-metal explained they set those events in music clubs to be able to see their fans up close, and Moametal said that she had wanted to perform in front of different audiences.

[18] Others, particularly international audiences who won tickets via lottery, complained that it was unfair to be barred from shows due to not being in the correct age range.

The Chosen 500 was announced on September 22, 2017, and released exclusively to a select five hundred "The One" fanclub members on January 20, 2018.
