ONE LOVE ONE HEART

ONE LOVE ONE HEART (Japanese: ワンラブワンハート, shortened to ラブワン) is a nine member Japanese group with both male and female members, formed on 28 January 2022 as a joint project between Stardust Promotion and Avex. Shibuya in Tokyo is built into the group concept.

The group debuted on 27 April 2022 with the distribution single Now or Never and describes itself as a youth entertainment group rather than a conventional idol act. Isshin Aihara, one of the members, holds a profile of his own in this catalogue for his acting work.

Sources list the line up slightly differently from one another, and the fandom name is given as both LOVEART and LOVEat, so both readings are noted rather than one being chosen.

ONE LOVE ONE HEART has settled into a yearly rhythm, releasing an album each January: LOVE1 in 2023, 愛せ、至極散々な僕らの日を in 2024, ゆれる青春 in 2025 and 約束のパスポート, an eleven track fourth album, on 28 January 2026. The group has played one man lives at venues including Zepp Shinjuku and Shibuya Stream Hall, and footage from the Oneman Live 2025 SPARK of LOVE, held at Hulic Hall Tokyo on 20 July 2025, was included on the fourth album’s Blu-ray edition.

The line up has performed as nine members since June 2023, having started as a ten piece. The group also runs an official fan club app, LOVE at, which handles advance ticketing, and a weekly Spotify programme called ONE TALK ONE TIME.
