Halzion
2020 song by Yoasobi
"Halzion" or "Harujion" (Japanese: ハルジオン; lit. 'Philadelphia fleabane') is a song by Japanese duo Yoasobi from their debut EP, The Book (2021). It was released as a single on May 11, 2020, through Sony Music Entertainment Japan. The song depicts the protagonist who spends days of disappointment after parting with her lover, finding hope while re-questioning her dreams and the meaning of life, and regains her motivation to move into the future. The English version of the song was included on the duo's second English-language EP E-Side 2, released on November 18, 2022.
"Halzion" was based on Soredemo, Happy End, a short story written by Hashizume Shunki, marking the first time that Yoasobi collaborated with a professional novelist. Unlike the duo's former two songs, the source material was not based on the novel-centered social media Monogatary.com. The song and the story it is based on were released as part of an advertising campaign Immersive Song Project by Suntory, to promote their new energy drink branded Zone.
Usage in media
Besides Zone, "Halzion" also appeared in EA's 2014 video game, The Sims 4, which was added into the base game via the November 10, 2020 game update. It can be heard through the S-Pop (Sim-Pop) radio station and has been re-written in Simlish language. Additionally, the song appeared on the 2020 Gekidan No Meets stage Mukō no Kuni, and Nintendo Switch 2021 televised advertisement Jibun Jikan-hen.
This brief starts where responsible research should: with the source description of “Halzion” as 2020 song by Yoasobi. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the arts & letters register because the source frames it as 2020 song by Yoasobi. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q97310622. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2021, 2020, 2022 and 2014.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
