@onefive

@onefive (ワンファイブ) is a Japanese four-member girl group consisting of Kano Fujihira, Soyoka Yoshida, Tsugumi Aritomo, and Momoe Mori. The group was formed in October 2019, in the year all the members turned 15 years old. In addition to music, they have been involved in modeling, acting, and other activities while focusing on their "Japanese Classy Crush" concept. They are represented by the talent agency Amuse Inc. and are signed with the record label Avex Trax.

Name
The name @onefive was chosen because the members were 15 years old at the time of formation, and because it can be pronounced in Japanese as ichi-go (lit. "one-five"), referring to the concept of ichi-go ichi-e, which the members value. The "@" symbol, which is silent, was included in the name to mean "from us" and "now from this place". Fans of @onefive are collectively referred to as @fifth.

2019–2021: Formation and early years
@onefive was formed in October 2019 by the four graduating members of the Japanese idol group Sakura Gakuin, including Kano Fujihira, who was one of the kawaii metal band Babymetal's three rotating "Avengers" support dancers. On October 15, 2019, the group created social media accounts on Twitter, Instagram, and YouTube, but the identities of its members were kept secret. On October 19, 2019, while the members were still in Sakura Gakuin, their identities were revealed during the Sakura Gakuin Festival 2019 at the Kanagawa Arts Theatre. During the encore of the show, after performing as members of Sakura Gakuin, they performed their debut single "Pinky Promise" as @onefive for the first time. The choreography for the single was created by Mikiko.

Shortly after its formation, the group was unable to perform in-person events due to the COVID-19 pandemic, relying instead on an online presence to hold virtual events. Notable virtual events included the release event for the CD single "Mada Minu Sekai" (まだ見ぬ世界) on July 19, 2020, and the concert @onefive Online Live: Blue Winter 2020 on December 22, 2020. The music video for the song "Mada Minu Sekai" was recorded by the four members at their own homes during the pandemic.

In January 2021, @onefive collaborated with the Japanese fashion brand Apres Jour for the outfits worn in the music video for "BBB". The choreography for the song was created by Minako "Maru" Maruyama of Elevenplay.

On November 1, 2021, the song "Just for You" was featured in the Christmas commercial of the Japanese jewelry brand The Kiss.

On November 24, 2021, the digital single "Underground" was released, which marked the first time that the members created their own choreography. They were also intimately involved in the production process of the music video, sharing their ideas on hairstyles, makeup, outfits, visuals, and cuts. The process was documented, with an emphasis on the choreography, in a four-part documentary series released on YouTube titled Their Underground (彼女たちのUnderground, Kanojo-tachi no Underground).

2022: 1518, major label debut, and TV drama
On February 2, 2022, @onefive released its first studio album, titled 1518, and pronounced ichi-go ichi-e. The "18" in the title represented the age that the members would be turning in the year of the album's release. The song "1518" on the album marked the first time that the members wrote their own lyrics. The album also highlighted @onefive's desire to be "a group that grows up with the same generation". All of the songs apart from "1518" had their lyrics primarily written by a female high school student and singer-songwriter called Yura, who was the same age as the members of @onefive. Furthermore, the music video for "Lalala Lucky" was produced in collaboration with students of N High School and in cooperation with Adobe. "Lalala Lucky" was also featured in a web commercial for the Japanese hair dye brand Beautylabo.

On February 20, 2022, as the circumstances surrounding the COVID-19 pandemic continued to change, the group was able to hold its first in-person solo concert with an audience, titled @onefive 1st Live: 1518, in Osaka at the Umeda Club Quattro. This was followed by a second concert under the same title on March 6, 2022, in Tokyo at the Shibuya Club Quattro. During the second concert, @onefive performed a dance to the song "Let Me Go" by Yūki Tsujimura, who was prominently involved in the music production of the first album. The choreography and stage lighting for the dance performance were produced by Kano Fujihira.

@onefive's first festival performance was at Super Mawa Loop Osaka 2022 on May 8. Other festivals included Sakae Sp-ring 2022 on June 5, Yatsui Festival 2022 on June 19, and Spark 2022 in Yamanakako on July 18.

In October 2022, @onefive made its major label debut with Avex Trax when "Miraizu" (未来図) was featured as the theme song for the live-action television drama adaptation of the manga If My Favorite Pop Idol Made It to the Budokan, I Would Die. The four members of @onefive were cast in the drama as members of the fictional idol group ChamJam. Namely, Fujihira as Maki Hakata, Yoshida as Yumeri Mizumori, Aritomo as Yūka Teramoto, and Mori as Sorane Matsuyama. The drama was broadcast for ten episodes on ABC TV and TV Asahi from October to December 2022. "Miraizu" was performed in a live setting for the first time on the first day of the @onefive Live 2022: Spotlight concerts, held in Osaka at the Umeda Club Quattro on November 6, 2022, and in Tokyo at The Garden Hall on November 13, 2022.

2023: @fifth, live-action film, and Amazon Fashion
The official fan community service of @onefive was established on January 15, 2023, in the form of a subscription-based mobile application called @onefive Premium.

The community was renamed to @fifth later that year and serves as the official fan club of @onefive.

The concert @onefive Live 2023: ChancexChange, which was held in Tokyo at the Ex Theater Roppongi on April 9, 2023, marked the first time that the audience could sing and cheer out loud, being no longer restricted by the COVID-19 pandemic. It also coincided with the transition of the members of @onefive from high school to university, a "change" that they each elaborated on during the conversational parts of the concert.

On May 12, 2023, the live-action film adaptation of the manga If My Favorite Pop Idol Made It to the Budokan, I Would Die was released with "Chance" as its theme song.

November 17, 2023, marked the creation of the group's official characters, or mascots, called @chib15, pronounced chibi five. Each of the four members designed their own character: Laa the lion by Fujihira, Babu the chick by Yoshida, Zoey the fawn by Aritomo, and Mimi the rabbit by Mori.

It was announced on December 1, 2023, that @onefive would be a participating artist in the NTV Imaginarium 2023 metaverse festival, which was organized by Nippon TV in commemoration of the broadcasting corporation's 70th anniversary. The festival had a virtual reality component utilizing the Japanese metaverse platform Cluster, as well as a real life component in the form of an art exhibition at the Museum of Contemporary Art Tokyo. The members of @onefive created pieces of pixel art depicting their @chib15 characters for the festival, which were both physically displayed at the exhibition and virtually granted as NFTs to those who purchased tickets to the metaverse venue in Cluster. A series of virtual events had been planned to take place at the metaverse venue from December 9, 2023, to March 3, 2024, involving the various participating artists. @onefive's event was a metaverse party where attendees would dress their avatars in neo-retro style clothing, as seen in the music video for "F.A.F.O", and dance to the group's music.

In the final quarter of 2023, the group held two concerts under the title @onefive Live 2023: No15e Maker. The first concert, subtitled Underground, was held in Osaka at the Yogibo Meta Valley on November 25, 2023. The second concert, subtitled Overground, took place in Tokyo at the Ex Theater Roppongi on December 21, 2023. The two subtitles referred to the process of rising from the underground. At the conclusion of the second concert, it was announced that @onefive's second studio album would be released in the spring of 2024.

2024–present: Classy Crush and national tour
On April 8, 2024, the song "Mr.Gorgeous" was featured in a commercial for Amazon Prime Video.

On April 17, 2024, @onefive's second studio album and first major label album, titled Classy Crush, was released. The album contains songs that depict strong Japanese girls, including its lead song "OZGi", pronounced ojigi, which was produced with the theme of "Japanese Classy Crush". "Classy" refers to old things, stereotypical images and ways of thinking, and conventional ways of doing things. "Crush" expresses @onefive's desire to destroy things of that nature, which hold them back, and to move forward in a new way. "Japanese" emphasizes the cultural origins of the members of @onefive, including practices such as bowing, calligraphy, and ikebana, which they would like to preserve and promote. Classy Crush charted at number 16 on the weekly Oricon Albums Chart.

@onefive's first national tour was announced on April 1, 2024, scheduled between August 17 and September 15, 2024.
