JO1

JO1 (ジェイオーワン) is the final group of the audition show Produce 101 Japan formed with its top 11 contestants in 2019.

Their fans are called "JAM" which stands for: J for "JO1", A for "and", and M for "Me". "JO1 and Me", meaning "JO1 and the fans".

Pre-debut: Formation through Produce 101 Japan
JO1 was formed through the Japanese version of the South Korean reality competition show Produce 101 titled Produce 101 Japan, which aired from September 25 to December 11, 2019. A total of 6,000 people auditioned for the show, out of which 101 contestants were chosen. Every male Japanese citizen between the ages of 16 and 30 without any ties to an entertainment company was eligible to apply. Contestants had to go through several rounds of evaluations before the top eleven were chosen by viewers through online voting and announced via live broadcast on TBS. The winners then signed with Lapone Entertainment, a joint company between Yoshimoto Kogyo and CJ E&M.

Prior to appearing on the show, several members had already been active in the entertainment industry. Kawashiri Ren attended Very Merry Music School and worked as a professional back-up dancer for artists like SMAP, Dreams Come True, F.T. Island, Wanna One, LBH, Yamashita Tomohisa, and Pentagon. Shiroiwa Ruki is a former member of Johnny & Associates' trainee group Johnny's Jr. and was part of the voice actor music group Tsukicro in 2017, where he was set to portray the character Hibiya Ruki but he ultimately left the group before their official debut.

Prior to their debut, the group held their first fanmeeting on January 31, 2020 at Pacifico Yokohama and at Osaka Orix Theater from February 18 to February 20, 2020.

2020: Debut with PROTOSTAR and first studio album: The STAR
Shortly after the end of Produce 101 Japan, the group flew to South Korea to train for their debut and record their first single. On December 24, 2020, Mnet denied rumors that the group went to South Korea to debut there and stated that JO1 would mainly promote in Japan and that their debut album would also not include Korean songs.

On January 14, it was revealed that the group's debut single would be titled Protostar and that it would be released on March 4 of the same year. Protostar was an immediate commercial success, selling more than 320,000 units in the week of its release and peaking at number one on both the Oricon Weekly Singles Chart and Billboard Japan Japan Top Singles Chart. Its title track "Infinity" also peaked at number one on the Billboard Japan Hot 100. The song was aired for the first time on February 5, 2020 on J-Wave's radio station Step One and they gave their first live performance of it on the NTV morning show Sukkiri. Protostar was certified Platinum by the RIAJ for surpassing 250,000 copies sold and was also featured in various mid-year rankings, such as Oricon's 2020 Mid-Year Ranking on June 19 and Billboard Japan's 2020 Mid-Year Top Artists ranking.

The group was scheduled to perform at KCON 2020 JAPAN's main event KCON 2020 JAPAN x M COUNTDOWN on April 4, 2020 at Makuhari Messe. Since the event was canceled due to the coronavirus outbreak, they attended KCON:TACT 2020 SUMMER for a Meet & Greet instead, making them the first Japanese boy group to ever participate in the convention.

On June 21, 2020, after their performance at KCON:TACT 2020 SUMMER, JO1 announced the release of their second single album Stargazer for August 26, 2020. The song "My Friends" was written by member Yonashiro Sho and choreographed by Kawashiri Ren. The single debuted at number one on the Oricon Weekly Chart and the Billboard Japan Top Singles Chart. Just like "Infinity", their new title track "OH-EH-OH" ranked first on the Billboard Japan Hot 100. Additionally, as both Protostar and Stargazer ranked first on the Oricon Weekly Chart, they became the first artist to earn two consecutive wins on the chart since Hinatazaka46's "Do Re Mi Sol La Si Do" on July 29, 2019. Stargazer was certified Platinum by the RIAJ. On September 5, the group performed as the headliner for the 31st Mynavi Tokyo Girls Collection 2020 Autumn/Winter 2020, the largest fashion event in Japan, at Saitama Super Arena. On October 16, the group released the first version of their official lightstick. They also performed at KCON:TACT Season 2, which took place from October 16 to October 25, 2020.

Both songs charted in Japan Hot 100, while the lead track "Real" peaked atop the chart. Stranger was the group's fastest single to surpass 400,000 copies sold on the Billboard Japan charts. JO1 later participated in a joint live concert, KCON World Premiere: The Triangle, on September 23 at the Pacifico Yokohama, alongside other Produce 101 Japan subsequent groups: OWV and Enjin. It was JO1's first performance with a live audience since they debuted. On October 9, Lapone Entertainment announced that member Sukai Kinjo, who had missed the concert, would suspend his activities after being diagnosed with adjustment disorder to receive treatment.

On November 19–21, JO1 held their first live concert, the 2021 JO1 Live "Open the Door", at the Makuhari Messe, instead of the planned national tour to comply with the COVID-19 preventive measures. Between the five shows, the concert amassed a total of 45,000 audiences in attendance. It featured songs from the group's next single, Wandering. The single was supported by double lead tracks, "Bokura no Kisetsu" (僕らの季節, Our Season) and "Prologue". The latter was produced by UTA [ja] and used as the ending song for the anime series Boruto: Naruto Next Generations. Prior to his break, Kinjo managed to participate in the recording of the single except for the song "Oasis".
