Aimer (エメ, Eme) is a Japanese pop singer and celebrated for her rich, husky voice that conveys deep emotion, ranging from vulnerability to intensity, and for her prominent role in composing and performing theme songs for series and films. Hailing from , she has cultivated an enigmatic public image as a "faceless voice," rarely showing her face in music videos or brightly lit performances to emphasize her vocal artistry over visual presence, though she made a rare full reveal during a 2016 appearance on the television program Music Station. Aimer made her major debut on September 7, 2011, with the single "Rokutousei no Yoru" (alongside "Kanashimi wa Aurora ni" and "Twinkle Twinkle Little Star"), which served as the ending theme for the anime series NO. 6 and peaked at number 28 on the Oricon weekly singles chart. Initially signed to Defstar Records (a sublabel of Sony Music Entertainment Japan), she transitioned to Sacra Music in 2021 while being managed by Agehasprings; her stage name draws from the French verb aimer, meaning "to love" or "to like." Over the course of her career spanning the and , Aimer has released eight studio albums, including Sleepless Nights (2012), Penny Rain (2019), Walpurgis (2021), and Open α Door (2023), alongside numerous singles and best-of compilations like Best Selection "Blanc" and Best Selection "Noir" (both 2017). Her music blends and rock elements, often exploring themes of longing, resilience, and introspection through her own lyrics. Aimer's most notable achievements stem from her anime collaborations, where she has provided opening and ending themes for major productions such as Demon Slayer: Kimetsu no Yaiba—including the opening "Zankyosanka" (2021–2022), which held the number-one spot on the Billboard Japan Hot 100 for a record seven consecutive weeks and nine total weeks, and the ending "Shiawase" (2021)—as well as the ending "Deep Down" for Chainsaw Man (2022), endings for the Fate/stay night: Heaven's Feel film trilogy (2017–2020), an ending for Bleach (2011), and the theme "Taiyō ga Noboranai Sekai" for the Demon Slayer: Kimetsu no Yaiba film To the Infinite Castle (2025). These works have not only topped Japanese charts but also garnered international acclaim, contributing to her reputation as one of Japan's leading voices in anime music and live touring, including sold-out arena shows and festival appearances.

Early life

Childhood and family background

Aimer was born in , , in 1990, though the exact date has not been officially confirmed by the artist herself. She grew up in a household immersed in music, as her father worked as a professional in a rock band, exposing her to various genres from an early age. This environment fostered her innate interest in music during her formative years. As a child, Aimer began studying piano in elementary school, developing skills that led her to compose her own songs by her teenage years; she initially dreamed of pursuing a career in music performance.

Musical influences and vocal development

During her adolescence, Aimer drew significant inspiration from Japanese artists Ringo Sheena and Hikaru Utada, whose intricate pop and alternative styles shaped her early songwriting and performance aspirations. She also admired the pop-punk energy of Avril Lavigne, which prompted her to pick up the guitar in middle school and experiment with English lyrics in her compositions. These influences spanned rock, pop, and alternative genres, reflecting the diverse musical environment of her upbringing influenced by her family's involvement in music. At the age of 15, Aimer experienced a sudden loss of her voice due to overstraining her from excessive singing, resulting in a of vocal nodules that required nearly a year of silence therapy for recovery. This traumatic incident initially left her unable to speak or sing, but upon regaining her voice, it had transformed into a distinctive timbre characterized by emotional depth and a lower register, which she now views as a pivotal that enabled her professional path. Initially self-taught in her musical endeavors, including basic singing and guitar playing inspired by her idols, Aimer developed control over her altered range through practice and collaborations, allowing her to handle both delicate ballads and more powerful expressions.

Career

2011–2015: Debut and breakthrough singles

Aimer made her major debut on September 7, 2011, with the triple A-side single "Rokutousei no Yoru / Kanashimi wa Aurora ni / " under Defstar Records, a sub-label of .

Her second single, "Re:pray / Sabishikute Nemurenai Yoru wa," followed on December 14, 2011, with "Re:pray" selected as the 29th ending theme for the anime . The release included a cover of Lady Gaga's "Born This Way" on its B-side, showcasing Aimer's versatility in blending original material with reinterpretations. This single topped the Mora digital download charts, highlighting her growing digital presence. In 2012, Aimer continued building momentum with her third single "Yuki no Furu Machi / Fuyu no Diamond" in February and her fourth single "Anata ni Deawanakereba Kasetsutouka / Hoshikuzu Venus" on August 15. The latter's title track functioned as the ending theme for the Fuji TV Natsuyuki Rendezvous and achieved significant acclaim, ranking fifth on Keisuke Kuwata's list of the top 20 songs of 2012. These releases solidified her reputation for emotive ballads tied to narratives, attracting a dedicated audience among viewers. Aimer's debut studio album, Sleepless Nights, arrived on October 3, 2012, compiling tracks from her initial singles alongside new material like "Yoru Gyakousha Nothing to Lose" and "Egao." The album peaked at number five on the daily chart and number 11 on the weekly chart, earning a nomination for the 2012 CD Shop Awards for its atmospheric production and lyrical depth. It represented a breakthrough in establishing her sound, characterized by introspective themes and orchestral arrangements. Her second studio album, , was released on June 25, 2014, peaking at number 18 on the weekly albums chart and featuring tracks like "Sakasama no Chou" and "Kataomoi," further exploring her emotive style with orchestral and rock influences.

It reached number six on the weekly chart, underscoring her rising commercial traction.
