Aiko (Japanese singer)

Aiko is one of the few artists whose music was not available on any subscription streaming services in Japan for many years. However, from midnight on 26 February 2020, her catalog became available on major subscription platforms. On 14 December 2021, during the final show of her concert tour "Love Like Pop Vol. 22", she told fans that she had married a younger man sometime in 2020. They first met when one of Aiko's friends attended her concert together with him; he had long been a fan of Aiko. Notation in songwriting credits While her stage name as a singer is written as "aiko", her songwriting credits are registered as "AIKO". She had decided before her major debut that she wanted to use a romanized name, but had not firmly settled on whether it would be written in upper- or lowercase letters. When she applied to JASRAC, it ended up being registered in all caps as "AIKO". On the omnibus album Dōtei Omnibus CD Vol.1, both the artist name and the lyricist/composer credits are written as "AIKO", but from astral box onward, the artist name has been written as "aiko" while the lyricist/composer credits remain "AIKO". Official Fan Club The official fan club is called "BABY PEENATS". The name was coined by Aiko herself, inspired by Snoopy, which she loves. == Music career ==

In April 1996, Aiko became a radio host of FM Osaka after graduating from college. She released a CD which she produced independently with her friends of college in August. She participated in "The 5th Music Quest Japan Final" on 10 October, and was awarded the Excellence Award shared with Ringo Shiina. She released an EP on an independent label in 1997, followed by a single and a mini-album in 1998. In July 1998, Aiko debuted on a major label with her first single, "Ashita" (あした), which was used as the theme song for the movie Toire no Hanako-san. In 1999, her fourth single "Hanabi"(花火) became a smash hit. In 2000, her second album, Sakura no Ki no Shita (桜の木の下), reached number one on the Oricon weekly charts, with the total CD sales amounting to 1.4 million copies. Her sixth single, "Boyfriend", sold over 500,000 copies and became her best-selling CD single. She made her first appearance in NHK's 2000 Kohaku Uta Gassen. == History ==

Before Major Debut Aiko was born on 22 November 1975 in Suita, Osaka Prefecture. Due to family circumstances, she spent some time living at a relative's house from her upper elementary school years, and it was around this time that she began aiming to become a singer. As a junior high school student, she told family friend and singer-songwriter Hiroshi Madoka about her dream of becoming a singer, but he advised her against it, saying that it would be a difficult path. In high school, she began composing songs on the piano. While attending Osaka Prefectural Higashi-Yodogawa High School, she served as vice president of the student council and also played in a band with friends until graduation. In May 1995, while enrolled at Osaka College of Music Junior College, she participated in the 9th TEENS’ MUSIC FESTIVAL and performed "Aitsu o Furimukaseru Hōhō" ("How to Make Him Turn Around"), a song she had written and composed herself,[note 2] winning the Grand Prix. In April 1996, after graduating from junior college, she became a presenter on FM Osaka's COUNTDOWN KANSAI TOP40, and subsequently hosted three radio programs in total.[note 3] Around August of the same year, she released the independently produced Dōtei Omnibus CD Vol.1, created jointly with friends as her graduation project. In October, she entered The 5th MUSIC QUEST JAPAN FINAL, where she received the Excellence Award alongside artists such as Ringo Sheena. [note 4] In 1997, a producer from Pony Canyon contacted Aiko after noticing her at contests, and on 20 December she released the indie album astral box. In 1998, she released her first indie single "Hachimitsu" and her second indie album GIRLIE. In April, she was approached to sing a film theme song, and talks progressed toward her major-label debut. == Major Life Debut ==

In July 1998, Aiko made her major-label debut with her first single, "Ashita." The song was used as the theme for the film Shinsei Toilet no Hanako-san, gaining significant attention particularly on FM radio stations in the Kansai region. She also held her first solo concert, "LOVE LIKE POP!", at Esaka Boomin Hall. In 1999, her third single "Hanabi" became a hit, remaining on the Oricon charts for an extended period. She also made her first appearance on Music Station, bringing her national prominence. In 2000, her second album Sakura no Ki no Shita reached No.1 on the weekly Oricon chart. The album became a major commercial success, selling 1.4 million copies and earning the Japan Gold Disc Award for Rock Album of the Year. The single "Boyfriend," released the same year, sold over 500,000 copies and led to her first appearance on the 51st NHK Kōhaku Uta Gassen. In 2001, her album Natsufuku became her second consecutive million-seller and again received the Japan Gold Disc Award for Rock Album of the Year. In July, she began the concert tour "LOVE LIKE POP Vol.6." During the Fukuoka performance, she injured her throat and was later diagnosed with acute laryngopharyngitis caused by vocal nodules. Some performances were postponed, but after recovering, she held additional shows and successfully completed the tour. In 2003, Aiko appeared in her first television commercial, for Glico Café Au Lait, which aired nationwide. Both Kyushu-only versions (Miyazaki and Kagoshima) and national versions were produced, featuring her songs "Chōchō Musubi" and "Andromeda." On 30 August, she held her first outdoor guerrilla free concert, "Love Like Aloha," at Katase Nishihama Beach. Despite being announced only shortly beforehand on mobile sites and her official website, the event attracted 25,000 attendees. In October, she performed at Aoyama Gakuin University's school festival, her first such appearance in about four years. In 2005, her single "Kira Kira" was selected as the theme song for the television drama Ganbatte Ikimasshoi. Her artist book aiko bon was published by Sony Magazines, detailing aspects of her upbringing and path to debut that had rarely been discussed previously. In Oricon's annual ranking, "Favorite Artists Selected by 20,000 Music Fans," she placed first for two consecutive years, 2005 and 2006. Following the release of Kanojo, the album debuted at No. 1 on the Oricon charts. On 30 August, she held her second outdoor guerrilla free concert, "Love Like Aloha Vol.2," at Southern Beach Chigasaki. Although a heavy downpour struck right before the show began, the event was completed successfully, drawing an audience of 25,000. In 2007, she released her first double A-side and 22nd single, "Hoshi no Nai Sekai / Yokogao." The song "Yokogao" was used as the theme song for the TV drama Hotaru no Hikari . In 2008, she released her 8th album Himitsu on 2 April. Celebrating the 10th anniversary of her major-label debut, she launched the campaign "aiko 10th Anniversary Chotto Ureshii Happy Surprise."

In 2009, her double A-side and 25th single "Milk / Nageki no Kiss" reached No. 1 on the Oricon Weekly Singles Chart for the first time in her career. It marked the first time in 7 years and 8 months that an artist more than 10 years post-debut achieved their first No. 1 on that chart, following N.M.L.’s "Zero Landmine." That same year, she provided the song "Ano Ko no Yume" as the theme for the NHK morning drama Welkame, and performed the song—which had not yet been included on any single or album—at the 60th NHK Kōhaku Uta Gassen (later included on the 2010 album BABY).

Beginning 18 April at Zepp Tokyo, she held Love Like Rock Vol.7, the longest and largest venue-based live house tour of her career (25 shows across 7 cities).

On 9 August, she announced the sixth edition of her outdoor free concert Love Like Aloha Vol.6, her first in three years. The concert was held on 30 August at Southern Beach Chigasaki and is said to have drawn about 37,000 attendees. In 2019, she provided the song "Melon Soda" as the campaign theme for FM802’s Access Project. The song was made available for limited rental at TSUTAYA. On 5 June, she released her first best-of album in eight years, aiko no Uta., a four-disc set compiling 56 tracks, including 42 single A-sides (including double A-sides) released up to that point, along with selected B-sides. On 29–30 August, she performed in Tatekawa Danshun 35th Anniversary Performance Tamayura ~tamayura~. Beginning 5 October at Zepp Tokyo, she held Love Like Rock Vol.9. Around this time, her longtime music producer stepped away due to various circumstances, and from then on her activities effectively shifted to self-production. In 2020, she released her 39th single "Aozora" on 26 February, featuring arrangements by Toomi Yoh. At the same time, her entire catalog became available on major subscription-based streaming services. She appeared as a guest vocalist on "Good Morning ~ Blue Daisy feat. aiko", a new track on Tokyo Ska Paradise Orchestra's best album TOKYO SKA TREASURES – Best of Tokyo Ska Paradise Orchestra released on 18 March. This marked her first release of a song written and composed by someone else since her debut single. Along with "Aozora," she also performed with Tokyo Ska Paradise Orchestra on music programs. Due to the spread of COVID-19, her Zepp Tokyo performances scheduled for 7–8 March were postponed, with new dates set for December 2021.

On 30 August, she premiered the online event Love Like Aloha Memories: Sunahama ni Motte Ikareta Ashi on her official YouTube channel, featuring re-edited footage from past Love Like Aloha concerts, including some previously unreleased clips. She also made a surprise appearance in the ending, announcing her upcoming online concert. Although a national tour had originally been planned for late 2020, it was postponed without announcement due to the pandemic. On 17 October, she held her first paid, pre-recorded no-audience online concert, Love Like Rock ~ Betsuwaku-chan vol.2 ~. As with a regular tour, merchandise was sold, and streaming ticket purchasers received physical items including paper tickets, questionnaires, and silver tape used in special effects. Four days later, on 21 October, she released her 40th single "Honey Memory." In 2021, on 3 March, she released her 14th album Dōshitatte Tsutaerarenai Kara, her first album in 2 years and 9 months. She was scheduled to begin the national tour Love Like Pop Vol.22 on 14 May, but five performances—including opening night—were postponed due to the extension of Japan's state of emergency and event guidelines in response to COVID-19. The tour officially began on 8 June at Tokyo Garden Theater. Due to infection conditions and local government guidelines, four additional performances in the Kanto region scheduled for 19 August, 31 August, 1 September, and 7 September (the 7 September Hachioji performance was originally the 14 May opening show, postponed again) were postponed but eventually completed on 14 December. The postponed final two dates of Love Like Rock Vol.9 from 2020 were rescheduled and held over five days—1, 2, 6, 7 December, and 22—at Zepp Tokyo. Because of event restrictions, all shows were fully seated rather than standing, but all were successfully held.

On 14 December 2021, Aiko revealed on her live show performance that she had tied the knot with her significant other a year earlier. Influences The artists that Aiko has been influenced by include KAN, Sugar Babe, Yumi Matsutoya, DREAMS COME TRUE, Carole King, Jackson 5, Billy Joel, Stevie Wonder, and others. She is also a fan of Southern All Stars and has covered their songs, as well as songs by Keisuke Kuwata, in free live performances at the Southern Beach Chigasaki. Kuwata has praised Aiko, calling her "a wonderful person," and in 2013, she covered "Kabutomushi" at the "Act Against AIDS 2013 Showa 88th Year! Second Solo Red and White Song Battle". Musicality Aiko tends to use chord progressions influenced by jazz. According to Seiko Kikuchi, her compositions are based on the blue note scale, which can be said to give her a blues-singer style. While Aiko is often featured in the media for her thoughts on romance and fashion, when her music is covered, it's often focused solely on the lyrics, though her melodies and chord progressions also reveal extraordinary qualities. During her "Love Like Pop" live tour series, she would improvise songs using keywords from the audience, showcasing her versatility as a melody maker . In 2020, in response to a request from Takashi Okamura (Ninety-Nine), she created the song "White Peach" on the spot. She shared it on her Twitter account, proving that her sense of creativity was still sharp. Aiko has absorbed various genres from both Western and Japanese music, and according to her producer, the genre of her songs changes depending on the period of creation. For those familiar with music theory, Aiko's songs may feel unusual in terms of chord progressions before the arrangement and chorus are added. It is often said that she intentionally uses strange chord progressions and melodies, which sometimes causes discomfort during the demo stages. Despite this, she has never thought that her songs are strange. This approach began when she was surprised by the many rules in music school. She wanted to make music freely, as the songs she sang as a child felt more liberated. Her producer advised her not to memorize technical jargon but to communicate the sounds she hears in her head. Thus, she has adhered to a composition method that is free from logical thinking about chords. Even if the song's original form seems odd, she always manages to turn it into a pop song. For vocal takes, she freely sings during recording, and the producer selects the best take. Even when singing the same song, the melody changes slightly each time. Rather than worrying about whether it's pitch-perfect, she trusts the producer to choose the take that conveys the most emotion. Hobbies and preferences Her favorite sports are swimming and volleyball; she took swimming lessons from childhood alongside piano lessons, while volleyball was a temporary yet active involvement through a school club. She is also skilled at drawing, having provided illustrations for tour merchandise and for cover artwork of her single such as Sakura no Toki and DECADE. Aiko is an avid manga reader and often introduces her favorite works in magazines and tour pamphlets. These pamphlets have also included original illustrations contributed by manga artists. Since receiving a radio cassette player as a Christmas present in elementary school, she has also been a dedicated radio listener. Favorite and disliked food Likes: umeboshi (pickled plums), karashi mentaiko (spicy cod roe), yam. Dislikes: bamboo shoots, eggplant, mitarashi dango. Personal relationships Yuka – Originally a devoted fan of Aiko. When Aiko appeared on the Waratte Iitomo! "Telephone Shocking" segment, she introduced Yuka on the program. KAN – Considered one of Aiko's greatest artistic influences. In 2004, they performed "Kabutomushi" together at Act Against AIDS Live in Osaka. Aiko has also appeared as a guest on KAN's radio programs and concerts. She later joined the memorial project unit KAN with His Friends. Keisuke Kuwata (Southern All Stars) – They have frequently appeared together on programs such as Music Station (TV Asahi). Both artists have publicly covered each other's songs and expressed mutual admiration. When Kadokawa Shoten published a special feature on Aiko in 2014, Kuwata contributed a special essay. Sheena Ringo – As noted earlier, the two have known each other since before their major-label debuts. Porno Graffitti – They became acquainted when the band moved from their hometown to work in Osaka. Their relationship deepened after co-hosting radio programs, eventually forming the unit "Jaken 4 Kyoudai". Subsequent albums list each other in their "Special Thanks" sections ("Aiko" in Porno Graffitti's releases, and "Porno Graffitti" in Aiko's releases). Hiro Terahei – Has known her since before her debut. Aiko appeared on his radio program with each new CD release. Shinya Arino – Aiko was a fan and followed him enthusiastically during high school. Shinseido Machida (Record Store) – Two Shinseido stores—Lumine Machida and Machida Tokyu Twins—were widely regarded as "sacred place" for Aiko fans. Each location featured a dedicated Aiko corner, , given by Aiko herself. Some key characteristics are: • A permanent "Aiko" genre section existed alongside standard J-POP categories. • The Lumine Machida store closed on 31 July 2013, and relocated to Machida Tokyu Twins on 6 August 2013. The Twins store later closed on 30 July 2014. • Store staff members were appointed as " managers," a role passed down through generations. additionally, all major-label singles, albums, and DVDs were available for purchase. • A message box allowed fans to send notes directly to Aiko, which staff delivered to her; Aiko once shared a photo on her official site showing herself reading these messages. • The store was one of the few places where fans could listen to her independent-era recordings. • After relocation to Tokyu Twins, the Aiko section expanded in size, and a handwritten autograph from Aiko celebrating the reopening was displayed. == Concerts and live events ==

Aiko's live events and concert tours can be broadly categorized into three main types. First is the Love Like Pop tour, which primarily follows the release of an album after her major debut. Initially held in live houses, the tour later expanded to larger venues such as concert halls following her rise in popularity. Occasionally, large-scale concerts at arena-class venues such as the Nippon Budokan, Osaka-jo Hall, and Yokohama Arena feature "additional performances," which are not simply extra dates but often include substantial changes in the setlist and stage production to accommodate the larger venues. The second type is the Love Like Rock tour, which began in 2002 and visits live houses nationwide. This tour is characterized by its rock-inspired atmosphere in terms of song selection, composition, and costume choices. Despite her status as a top artist, Aiko maintains a bold and aggressive approach, continuing to serve her fans with a spirit of humility and passion. The third type is the Love Like Aloha tour, an occasional outdoor concert with no entrance fee. It consistently attracts 20,000 to 30,000 attendees despite usually being announced only a week in advance. This surprise event has become an annual late summer tradition for fans. The first event was held on 30 August 2003, at the western beach of Enoshima, Kanagawa, and subsequent events have been held in Chigasaki at Southern Beach on the same date in 2006, 2008, 2012, 2015, 2018, and 2024. Additionally, Aiko holds fan club-exclusive concerts, such as BABY PEENATS Meeting. Live performances Aiko is known for her highly praised live performances, which are often limited in number, turning each concert into a "platinum ticket" event. Despite performing around 20 songs per concert, the shows often extend for over 3 hours due to long MC segments. Venues range from Zepp-class to concert halls, sometimes featuring catwalks or other elements that reflect her personal touch in the stage design. These concerts are also marked by handmade touches, such as original questionnaires and creatively designed tour merchandise, which stand out in contrast to the polished productions typical of top artists. Her unique audience interactions during MCs, including her signature call-and-response chants like have also become popular, occasionally imitated by other artists. Additionally, Aiko has gained fame for collecting audience-suggested themes for impromptu solo performances. However, since the opening night of Love Like Pop Vol.20 on 8 June 2018, she has stopped performing these impromptu acoustic songs. Another notable characteristic is that, compared to other artists with similar career length and concert scale, Aiko's ticket prices remain relatively affordable. Setlist Aiko's setlists are often made up of songs she personally wants to perform at that moment. Even on album tours, not all songs from the album are guaranteed to be performed. Since Love Like Pop Vol.14, it has become common for two consecutive concert dates to feature almost entirely different sets. If the tour lasts a longer period, the setlist may change between the first and second halves, or the songs may be adjusted to reflect the season. As a result, a single tour can feature as many as four different setlists. However, the basic structure, such as the arrangement of fast and slow songs, has remained consistent over the years. In recent years, the usual encore has evolved into double or triple encores, often with unexpected songs added to the setlist. For example, at the final performance of Love Like Pop Vol.18 on 31 December 2015, at Osaka-jo Hall, after a countdown and double encore, Aiko performed an additional eight songs, totaling 33 tracks, and the concert lasted over four and a half hours. == Shows ==
