JO1 debuted on March 4, 2020, and was named Best 5 New Artists at the Japan Gold Disc Award. Since then, they have achieved seven consecutive Oricon number-one singles as well as six number-one songs and two consecutive number-one albums on the Billboard Japan Hot charts. They received the Excellent Work Award at the Japan Record Award for "Trigger", from their third studio album Equinox (2023). Their other accolades include three MAMA Awards and three MTV Video Music Awards Japan.

 

The name "JO1" was picked by Lapone Entertainment from recommendations made by the public (dubbed "national producers") via the official website of Produce 101 Japan. According to the initial suggestion, the letter "J" in the name refers to Japan, the group's origin nation, while the "O1" refers to the first year of the Reiwa, when the group was formed. However, "JO1" officially means that "the trainees who have dreamed together at Produce 101 Japan will become one and aim for the top of the world". The name was revealed in the final episode of the show.

2019: Formation through Produce 101 Japan

JO1 was formed through the reality competition show Produce 101 Japan, which was aired primarily on the streaming service Gyao! from September 25 to December 11, 2019. A total of 6,000 participants auditioned for the show, ranging in age from 16 to 30 and not affiliated with any talent agency. The final 11 trainees were picked by viewers from the 101 through online voting and announced during a live television broadcast on TBS. Unlike previous Produce 101 franchise-winning groups, there was no intention of restricting the group's activity after its debut.

Most of the Produce 101 Japan trainees had no experience in the entertainment industry, resulting in JO1 members having varying levels of experience. Ren Kawashiri and Shosei Ohira have previously worked as backup dancers for SMAP, Tomohisa Yamashita, Wanna One, Pentagon, and Exile among others. The latter, Keigo Sato, Syoya Kimata, and Issei Mamehara went to a local dance school; Kimata was also active as a cover dancer and Mamehara was a kid's dance teacher. Ruki Shiroiwa is a former member of Johnny's Jr., the trainee group of Johnny & Associates, and Tsukicro, a voice actor music group, while Shion Tsurubo spent ten months as a trainee at FNC Entertainment. Kawanishi, Kinjo, Kono, and Yonashiro had never received any dance or vocal training.

2020: Debut and The Star

JO1 headed to South Korea shortly after the conclusion of Produce 101 Japan to produce their debut single, Protostar, where they went through an "intense" one-month boot camp to strengthen their skills and chemistry as a group. The single was released on March 4, 2020, and debuted at number one on the Oricon Singles Chart with over 300,000 copies sold in the first week, making JO1 the seventh artist to accomplish so with a debut single, while its lead track, "Infinity", reached the top of the Billboard Japan Hot 100. On March 24, JO1 made their first live television appearance on NTV's morning show Sukkiri.

On August 26, JO1 released their second single, Stargazer, with Hui from the South Korean boy band Pentagon co-producing the lead track "Oh-Eh-Oh". Unlike the previous single, the production and training were done remotely due to the COVID-19 pandemic. On September 5, JO1 headlined the 31st Mynavi Tokyo Girls Collection Autumn/Winter 2020 in the Saitama Super Arena.

In November, JO1 released their first studio album, The Star, which debuted in second place on the Oricon Albums Chart and the Japan Hot Albums, trailing only Be by BTS. In December, JO1 made their first appearance at the FNS Music Festival, performing the promotional single "Shine a Light", and held their first live-streaming concert, Starlight, attracting an estimated 120,000 viewers from over 30 countries. JO1 received awards such as the Rising Star Award from the MTV Video Music Awards Japan and the Mnet Asian Music Award for Best Asian Artist. The group was also named one of the Best 5 New Artists at the Japan Gold Disc Award alongside SixTones, Snow Man, NiziU, and Yoasobi for their net sales in 2020.

2021–2022: Open the Door, Kizuna, and first arena tour

In February 2021, JO1 made their first appearance in South Korea on M Countdown and held their second online concert, Starlight Deluxe. Their third single, Challenger, was released on April 28 and became the eleventh best-selling single in the first half of 2021, with "Born to be Wild" topped the Japan Hot 100.

Their fourth single, Stranger, was released on August 18, and it was the group's fastest single to sell 400,000 copies on the Billboard Japan chart. On September 23, JO1 performed at the Pacifico Yokohama joint live concert KCON World Premiere: The Triangle alongside other Produce 101 Japan subsequent groups. It was their first performance in person since their debut due to the pandemic. On October 9, Lapone Entertainment announced that member Sukai Kinjo, who had skipped the event, would suspend his activities to receive treatment for adjustment disorder.

In November, JO1 held their first live concert, the 2021 JO1 Live "Open the Door", at the Makuhari Messe instead of the planned national tour. The concert drew 45,000 spectators in total and featured songs from the group's fifth single, Wandering, which became their first single to be certified double platinum by the Recording Industry Association of Japan (RIAJ). The single features "Prologue", the closing theme for the anime series Boruto: Naruto Next Generations.

Lapone stated on February 14, 2022, that Kinjo would resume his activities. JO1 later released two new songs, "Dreamer" and "Toberu Kara" (飛べるから, I Can Fly), as the theme songs for their first drama series Short Program and documentary film JO1 the Movie: Unfinished - Go to the Top. On April 22, JO1 released the digital single "YOLO-konde", produced by 3Racha of Stray Kids, whose concept development and lyrics writing process were shown on the NHK program This Is JO1 - Go to the Dream. In May, JO1 released their second studio album, Kizuna; the group's first number-one album on the Oricon and Billboard Japan charts. It includes "Move the Soul", the opening theme of Aniplex's original anime series Fanfare of Adolescence. JO1 embarked on their first arena tour to five prefectures in September and October, attracting 110,000 people.

2022–present: Debut on Kōhaku Uta Gassen, Equinox, and first Asian tour

JO1 released their first English song, "All Hours," in June 2022. Their sixth single, Midnight Sun, was released in October and sold 600,000 copies on the Billboard Japan chart in its first week, while the lead track, "SuperCali", spent two weeks in the top six of the Japan Hot 100. By the end of 2022, JO1 ranked high on several Billboard Japan's year-end charts, propelling them to number 25 on the Artist 100 chart. JO1 then made their debut on the NHK's annual New Year's Eve musical show Kōhaku Uta Gassen with "Infinity".

On April 5, 2023, JO1 released their seventh consecutive Oricon number-one single, Tropical Night, featuring "Tiger" as the lead track. JO1 performed the song to open the Hanshin Tigers vs. Hiroshima Toyo Carp match at Hanshin Koshien Stadium. In May, JO1 made their debut at the annual K-pop joint concert Dream Concert in Busan and headlined its Japanese edition the following month alongside Jaejoong and Junsu.

JO1 released their second consecutive number-one studio album, Equinox, on September 20, 2023. It includes the self-produced song "NEWSmile", the theme of the morning news show Mezamashi 8. In August, JO1 embarked on their second arena tour, Beyond the Dark, which included a performance in the Kyocera Dome, attracting approximately 200,000 people. The group also began their first Asian tour in November. On October 20, JO1 released "Eyes On Me" featuring DJ R3hab and made their debut on TV Asahi's prime time music program, Music Station. They are the second non-Johnny & Associates and LDH boy band to perform on the show after public criticism of the former's alleged influence on domestic rival groups' inability to appear on the show emerged. JO1 received the Excellent Work Award at the Japan Record Award in December for "Trigger" and performed "NEWSmile" as the first artist from the white team at the 74th NHK Kōhaku Uta Gassen.

In January 2024, JO1 released "Your Key" as the opening theme of the anime series Four Knights of the Apocalypse, which ranked first on Oricon's music DVD/Blu-ray chart upon its release as the group's first Blu-ray single on March 27.
