@onefive

Biography

@onefive (Japanese: ワンファイブ, Hepburn: Wanfaibu) is a Japanese girl group consisting of Kano Fujihira, Soyoka Yoshida, Tsugumi Aritomo, and Momoe Mori. It was formed in 2019, when the members were 15 years old. The group is active internationally in music, modeling, acting, and other endeavors. Differing from conventional Japanese idols, @onefive describes itself as a "new species of idol" that is not only kawaii, but also values live performance skills and creative involvement. With its "Japanese Classy Crush" concept, the group cherishes the culture of Japan while crushing stereotypes. @onefive is represented by the talent agency Amuse Inc. and is 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, Mada Minu Sekai, and BBB

@onefive was formed in October 2019 by four active members of the Japanese idol group Sakura Gakuin: Kano Fujihira, Soyoka Yoshida, Tsugumi Aritomo, and Momoe Mori. They adopted the stage names Kano, Soyo, Gumi, and Momo, respectively. Fujihira was also active as one of the three rotating "Avengers" support dancers for the kawaii metal band Babymetal, which originated as a sub-unit of Sakura Gakuin. 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×Pinky Promise20 October 2019 · SingleSpotifyYouTube Music (search)Tracklist · 1 track1Pinky Promise3:23" as @onefive for the first time. The choreography for the single was created by Mikiko. "Pinky Promise" was released as a digital single on the following day, October 20, 2019, officially marking @onefive's debut. 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. In May 2020, the members began a project in which they collaboratively produced merchandise with their fans through social media.
@onefive's first CD single, "Mada Minu Sekai" (まだ見ぬ世界), was released on June 24, 2020. The music video for the title track was recorded by the members at their own homes during the pandemic. The group also collaborated with Adobe on a photo collage contest for the single. On June 25, 2020, the first issue of the youth culture magazine Ite by Ohta Publishing featured @onefive on its cover, wearing the outfits for "Mada Minu Sekai". On June 29, 2020, a four-episode radio special hosted by the members called @onefive's Mada Minu Talk (@onefiveのまだ見ぬトーク) began on JFN Park. A live-streamed performance was held on July 19, 2020, to commemorate the release of the CD single.

2022: 1518, major label debut, and OshiBudō 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 title track "1518" marked the first time that the members wrote their own lyrics. They also choreographed the entire song. The other songs on the album, though not written by the members, also contain their thoughts and opinions. The music video for "Lalala Lucky" was produced in collaboration with students of N High School and in cooperation with Adobe. The collaboration highlighted @onefive's desire to be "a group that grows up with the same generation". "Lalala Lucky" was also featured in a web commercial for the Japanese hair dye brand Beautylabo. The members co-choreographed "Lalala Lucky" with Minako "Maru" Maruyama from Elevenplay.
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.

2026–present: Doh Yoh, Road to Budokan, and Sakuraization

The group's second EP, Doh Yoh×DOH YOH15 January 2026 · EPSpotifyYouTube Music (search)Tracklist · 6 tracks1Alps Vibes3:582KIBIDANGO3:093Magical Irony prod.☆Taku Takahashi (m‐flo)3:314Hot Air Balloon3:105Sleepless Night3:266KAWAII KAIWAI - Chinese Ver. - (Mobile Game "Strinova" Theme Song)3:20, was released on January 15, 2026.

@onefive launched its Road to Budokan initiative on April 1, 2026, with plans to perform at the Nippon Budokan by spring 2027. The goal was set for two reasons: first, due to the influence of playing the role of ChamJam in the live-action television drama and film adaptations of If My Favorite Pop Idol Made It to the Budokan, I Would Die; and second, since people of the same birth year as the members, 2004, would be job hunting and starting work after graduating from higher education around that time.
The Road to Budokan initiative began with a project called Sakuraization, in which the members embraced their origins in Sakura Gakuin as part of their journey toward the Budokan as @onefive. The first song from the project, "Kakumei Shōjo S" (♡革命少女S♡), samples "Heart no Hoshi" by Sakura Gakuin, and was released on April 15, 2026. The members were involved in the songwriting process through instructing their creative personnel on key words to include in the lyrics and on which parts of the original song to keep. The second song, "M1X5R×M1X5R20 May 2026 · SingleSpotifyYouTube Music (search)Tracklist · 1 track1M1X5R3:14", samples "Verishuvi" by Sakura Gakuin, and was released on May 20, 2026. The third song, "Muteki Atashi Mōdo" (無敵☆アタシモード), samples "Doki Doki Morning" by the Sakura Gakuin sub-unit Babymetal, and was released on June 24, 2026. It entered the Billboard Japan Heatseekers Songs chart. Babymetal's producer, Kobametal, gave his permission to sample "Doki Doki Morning", and Babymetal member Moametal said she supports @onefive's activities. The three songs were released as a music card titled Sakuraization on June 24, 2026. The @onefive Live 2026 "Sakuraization" concerts were held at the Ex Theater Roppongi in Tokyo on June 6, 2026, and at Bigcat in Osaka on July 3, 2026.
On October 7, 2026, "Vanilla Latte" became the ending theme song for the romantic drama Dekiai Kareshi no Tsukurikata: Se Kara Honmei ni Naru Onnanoko no Hanashi (溺愛カレシの作り方 セから本命になる女の子の話), broadcast on TV Tokyo. "Vanilla Latte" was released on October 8, 2026, and would later appear alongside "Serotonin" on the music card Serolla Latte on October 22, 2026.

Artistry

Differing from conventional Japanese idols, @onefive describes itself as a "new species of idol" (新種のアイドル, shinshu no aidoru) that is not only kawaii, but also values live performance skills and creative involvement. The members actively contribute their ideas to various aspects of the group's creative processes, such as song concepts, album sequencing, cover art, setlists, outfits, and merchandise. @onefive's lyrics often depict strong Japanese girls and incorporate the thoughts and opinions of its members. On certain occasions, the members have directly written lyrics or choreographed in part or in whole for recorded songs. For example, the song "1518" from the album 1518 was wholly written and choreographed by the members. They have also created special pieces of choreography and rewritten lyrics for live shows. Their live shows invite fan chants, circle pits, and rhythmic towel spinning.
The group promotes the good qualities of Japanese music while also incorporating elements of foreign music. Some of those elements have included hip-hop, rage, Afrobeat, dancehall, jungle, Jersey club, and Middle Eastern music. For example, "Kaguya×KAGUYA14 August 2024 · SingleSpotify (search)YouTube Music (search)Tracklist · 1 track1/1KAGUYA3:54" blends hip-hop, EDM, and traditional Japanese music. Hip-hop has been especially prominent, with the songs "Justice Day×Justice Day23 August 2023 · SingleSpotifyYouTube Music (search)Tracklist · 8 tracks · 2 discsDisc 11Justice Day3:182Like A3:453SAWAGE3:334Justice Day –Instrumental–3:185Like A –Instrumental–3:456SAWAGE –Instrumental–3:33Disc 21Justice Day (Music Video)3:362@onefive LIVE 2023 –Chance×Change– @2023.4.9 EX THEATER ROPPONGI(Live)", "ChocoLove", "Sit Down Please", and "Kibidango×KIBIDANGO22 October 2025 · SingleSpotifyYouTube Music (search)Tracklist · 1 track1KIBIDANGO3:09" serving as notable examples. Other genres include hyperpop and chiptune. The group's early music has been described as predominantly electropop, with songs like "Pinky Promise×Pinky Promise20 October 2019 · SingleSpotifyYouTube Music (search)Tracklist · 1 track1Pinky Promise3:23", "Mada Minu Sekai" (まだ見ぬ世界), and "BBB". The members have mentioned Blackpink, Perfume, Red Velvet, and Mamamoo as influences. In 2026, member Momoe Mori used the phrase "Babymetal × Perfume = @onefive" to describe the song "Muteki Atashi Mōdo" (無敵☆アタシモード).
While influenced by international sounds and artists, @onefive emphasizes its Japanese origins and identity with its "Japanese Classy Crush" concept. "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 their own new way instead. "Japanese" emphasizes the cultural origins of the members of @onefive, and indicates that while doing away with the negative parts, the group wishes to preserve and promote the parts of old, traditional Japan that are good and beautiful, such as bowing, calligraphy, and flower arranging. In this regard, the song "OZGi", which is a stylized spelling of ojigi, incorporates traditional Japanese culture in its music, lyrics, and choreography, especially with its "bowing dance". Likewise, "Kaguya" is inspired by The Tale of the Bamboo Cutter and contains a bon odori section. "Alps Vibes", as well, interpolates the melody of the dōyō "Alps Ichiman Jaku", and the outfits for the song include traditional Japanese elements, such as yagasuri, a type of kasuri pattern. Similarly, "Kibidango" reinterprets the dōyō "Momotarō" in the style of "kawaii hip-hop", and its choreography is reminiscent of kneading kibi dango confections.

Reception

Satoshi Shinkai, writing for Real Sound, lauded the group's singing and dancing as "incredibly high level" and "polished through rigorous training". Dai Tanaka from Barks opined, "The singing and dancing skills that @onefive has cultivated are very high." Spice's Endo pointed out the "professional quality" of the self-produced choreography for "Underground" and "Let Me Go". Pop 'n' Roll noted the "multifaceted nature" and "high quality singing and dancing" of the group during a self-choreographed performance of "Just for You" that was accompanied by member Soyoka Yoshida on the piano. Bhodhit Magazine's Yusei Abe observed, "Their live performances are certainly wonderful, but their personalities are truly lovely as well." Writing in English for Nante Japan, Hannah Lee described @onefive as "pushing the boundaries of what exactly is an 'idol' in today's sound". Tokyo-based American journalist Patrick St. Michel identified the quartet as an "idol alternative" that has "always been interested in the cutting edges of idol pop sound rather than its conservative core". Mexico's Revulsión evaluated the group's music as "sonically optimal for the international ear".
