Name

The group's name, JO1, was chosen by Lapone Entertainment among the suggestions given by "National Producers" through Produce 101 Japan's official website. According to the original suggestion, the “J” in JO1 refers to Japan, which is the origin of the group, while the “01” refers to the first year of Reiwa (令和) period where the group was first introduced.[3] The name was announced during the final episode of the show.[4]
