He has released nine studio albums and, with forty-eight singles released, holds the male soloist record for most top ten consecutive singles in Japanese music history. His single "Returner (Yami no Shūen)" (2007), is his first and only single to reach the number one spot on the Oricon charts. In 2007 became a founding member of S.K.I.N, a Japanese visual kei rock supergroup, and in 2010 formed his own band project Yellow Fried Chickenz. Besides being established in the modern entertainment industry and considered a pop icon, Gackt's music has been used as theme songs for video games (Dirge of Cerberus: Final Fantasy VII), video game films (Dragon Age: Dawn of the Seeker), anime series/films (New Fist of the North Star, Mobile Suit Zeta Gundam, Texhnolyze and Trickster) and television series (Kamen Rider Decade). In addition to his music career, Gackt has voice acted (including characters inspired by him in video games like in Bujingai and Genesis Rhapsodos in Crisis Core: Final Fantasy VII), and live acted in a few films, including a film he wrote, Moon Child, his international debut Bunraku, Japan Academy award nomination performance for Best Actor in Fly Me to the Saitama, and TV series most notably as Uesugi Kenshin in the NHK drama Fūrin Kazan.

Gackt was born on July 4, 1973, as the second of three children in a Ryukyuan family, in Okinawa of the Ryukyu Islands, Japan. His father was a music teacher, who primarily played the trumpet, and his mother was also a teacher. Gackt has an older sister and a younger brother. He lived in Okinawa until he was 7 years old (with short periods when was 16 and 26), because of his father's job, living in many different cities on Honshu and Kyushu islands in addition to Okinawa: Yamaguchi, Fukuoka, Shiga, Osaka, and Kyoto. He studied in the Moriyama High School in Shiga, and was enrolled in the Kyoto Gakuen University. Gackt's musical education began at age three when his parents initiated his classical piano education. At age seven, continuing his classical piano education became more difficult because of time spent at elementary school and the repeated change of instructors due to relocating from city to city. It would take another four years until his parents allowed him to quit lessons. However, after losing a piano competition to a boy he met in the middle school, Gackt voluntarily returned to his piano studies, even writing orchestral scores. He has credited the classical pianist and composer Frédéric Chopin with being "the one who taught me the beauty, depth, fun, sadness, the kindness of music; that music could grant people courage, and the meaning of the layers of sound. It isn't an exaggeration to say Chopin is the foundation of my music". Since his father played the trumpet, Gackt is also familiar with brass instruments. Having only listened to classical music and enka while growing up, he did not become interested in rock music until high school, and went on to master modern percussion.

In the early 1990s, Gackt was working as a host and dealer in a casino, while also being an assistant drummer for an amateur band. At the time he wanted to become more serious about his music activity but had a negative perspective on life. While at the casino, he met a businessman who inspired him to find a purpose in life, that being music. About a year later he left the band and he found himself working multiple jobs, among them as a sound technician at a studio where he could practice drums. When Gackt was twenty-years old, he met guitarist You Kurosaki, his future solo career support guitarist, at a music live house in Kyoto. They formed the band, Cains:Feel, whose name had biblical reference to the story of Cain and Abel. The group lacked a vocalist, so Gackt became the frontman, and the band went to record a demo tape before disbanding. In 1995, he was introduced to the visual kei band Malice Mizer which was on hiatus due to the departure of their frontman Tetsu. Gackt moved to Tokyo and joined them in October 1995. As their vocalist, pianist and primary lyricist on studio albums Voyage Sans Retour (1996) and Merveilles (1998), he also contributed three songs in their catalog, "Regret", "Hamon" and "Le Ciel", the latter being their most successful single as a band. During this time, the band's fame soared; and, after four years and two studio albums, in January 1999, it was officially announced that he left the band. According to his interviews and autobiography, the issues with the management office, members' differences, and his isolation from the band led to his departure.

Gackt launched his solo career on January 1, 1999. After completing his recordings, his first gig as a solo artist was the 99 Gackt Resurrection tour held in 11 locations across Japan. It was followed on May 12 with his debut release, the extended play Mizérable, released by Nippon Crown. The album peaked at number two, spending 12 weeks on the Oricon charts.

Gackt has a low-pitched voice with a vibrato pitch at D3-D4, and is capable of using falsetto, like for example in the songs "Ares" and "4th", among others. In his songs, he shows a wide range and often sings both low and high notes in the same song, sometimes also adding the falsetto. According to Gackt, he overextended his voice between 2003 and 2004 so searched for the right range until 2005, since which he has used a more restrained vocal style. His voice has been described as "very melodramatic", as well as "smooth, sleek, unnaturally heartfelt", "velvet" and "molasses".

His songs range from melodic ballads to intense hard rock songs, in which he masterfully combines "raw rock elements" with "listener-friendly compositions" and string instruments. Josephine Yun in A Concise Report on 40 of the Biggest Rock Acts in Japan (2005) noted his "talent for orchestration and for blending classical elements into the rock genre... and his style ranges from romantically classical to experimental and unfolding progressive rock". Some songs, like for example "Mind Forest", "Metamorphoze", "Returner (Yami no Shūen)", and those related to the album Last Moon, are distinctive for their blend of modern Western musical instruments and traditional Japanese musical instruments, a kind of music called by Gackt as "Zipangu rock" from which can be sensed it originates from Japan. Gackt often "stressed the beauty and importance of Japanese lyrics", writing "all of his music and lyrics to quality, not quantity". He uses double meaning words, and lyrics are "meaningful and heartfelt". They also deal with emotions of sadness, kindness, coexistence, beauty, fragility, depth of love for others and loneliness among many others. His process of writing songs and making concerts is by first writing the story, then writing and composing the songs based on it with a specific image in the live performance. It results in songs that are conceptually related, but still independent from each other. Most of his studio albums are conceived around two conceptual stories: story of "Moon Saga" (Moon, Crescent, Diabolos, Last Moon), set in Asia (mostly Japan) and Europe is a vampire story although by itself it is not, as the vampires were presented as a way of expressing a certain evil side and existence of humans. The theme is based around the existential questions of humanity, a symbolical and psychological story about the repetition of human sins, war and the question of what is the ultimate meaning of human life; and story of "Requiem et Reminiscence" or short "ЯR" (Rebirth, Re:Born), which is set in Nazi Germany during the World War II and questions where humans start and end and why at the same time destructive and loving, humanity decides to start wars.

Gackt's example of a more typical concert is D.r.u.g. Party tour (2006-2007) featuring his rock songs, with Oricon review noting his eroticism and charisma while performing, and Gackt considering it his and worldwide's pinnacle of an all-out androgynous style by a man. Another typical, yet physically intense concept, is that of his rock band Yellow Fried Chickenz (2010-2012, 2024–present). The Camui Gakuen festival shows (2009-2019) have Gackt performing cover versions conceptualized around a same-titled fictional school where Gackt acts as the student council president wearing a school uniform. He can be seen cross-dressing as a female, being a drummer of SEX Japan (pun on Yoshiki and his band X Japan), or a guitarist of The Balue Hearts (pun on The Blue Hearts) among others. In 2025, Gackt began a new live concept Maō shinfonī (魔王シンフォニー, Demonic Symphony / Demon King Symphony), fusing a rock band and more than 70-piece standing orchestra as one sonical ensemble, all wearing black robes and masks alike a "black mass", and in instrumental part Gackt is conducting the orchestra. It is also introducing to the classical music concerts an all-standing first floor, smoking effects, and more for a production of a "truly dark fantasy".

Gackt is considered a Japanese pop and fashion icon, J-pop/J-rock superstar and Japanese idol, and due to his involvement with the visual kei movement, which emphasizes androgynous and changing appearance, he is referred to as a "living manifestation of readers' fantasy men" found in bishōnen manga. Otaku USA magazine in 2007 stated "His 'more than human' appearance and persona were a hit with the mass media in Japan. It was as if a fictitious character suddenly popped out in the real world". He has been compared to fictional characters like Griffith from Berserk, Cloud Strife and Squall Leonhart from Final Fantasy, as well as having been an inspiration for manga characters. In his late career his appearance changed to more "macho". Gackt became associated with Japanese daimyo Uesugi Kenshin who he played in NHK Taiga drama Fūrin Kazan. Gackt was subsequently invited to act as Kenshin at Jōetsu city's traditional 82nd Kenshin Festival in August 2007. In August 2010 he participated in the 85th Kenshin Festival for the third time, with a record attendance of more than 240,000 visitors. Four more times he reprised the role in the festival, with a new record high number of 243,000 visitors in August 2015. Gackt's sex appeal has been noted by national polls, such as by Oricon, similar to those done by People. He often ranked highly in beauty listings, as the most or one of the most beautiful/sexiest Japanese men, celebrities or artists. In 2009, he was also ranked fifth among rock music personalities in Japanese history. Gackt on several occasions served as a fashion model (including for Yoshiyuki Konishi), producer and designer. In the first half of his career he had own jewelry & sunglasses brand Darts. In 2002 received Japan Glasses Best Dressed Award, and in 2003 Best Dressed Award by Japan Men's Fashion Association. In 2007 at the China Fashion Week in Shanghai received award for the Japanese Fashion Artist of the Year. Over the years, Gackt appeared as a performer, guest and regular member on several television variety shows, including Hey! Hey! Hey! Music Champ, and since 2009, TV Asahi's New Year's special Geinoujin-Kakuzuke-Check (Celebrity Rating Check), as of January 2026 he holds the record streak of 87 straight individual wins, building an image of a top connoisseur and "first-class entertainer". Gackt was one of the judges of Japan's first season of Got Talent show which premiered on February 11, 2023. Gackt appeared in many television commercials, including for Fujifilm, Shiseido, Daihatsu, Niconico, Tsutaya, Square Enix, and Konami, among others. From July 2014 to August 2016 in collaboration with Nestlé Japan was started a gaming channel "Game Center" with daily video release of Gackt playing video games, gathering more than 15 million views in first season alone. In 2019 became ambassador for PUBG Mobile in Japan, a collaboration that until 2023 saw him contributing original models of himself, skin outfits which wore in his career, weapon skins and voice pack. On July 31, 2008, Internet Co., Ltd. released Gackpoid, a Vocaloid using a recorded selection of Gackt's voice.

Gackt's other entrepreneurship projects include, among others, producing a line of sake "Chateau Gackt" in 2013. In 2016, he co-founded a real estate company with Satoshi Ikeda, named Gackt & Ikeda Asia Bridge Partnerz, in Kuala Lumpur. In 2017, he got involved as a core member and strategic advisor for Asia of a virtual currency project, Spindle. In 2019 was chosen as the executive organizer of the Japan Grown Diamond Association. In 2023 went on a long-term collaboration with a newly constructed winery and vineyard at Kaminokuni, Hokkaido.

The year 2007 saw the creation of the Save our Dears charity to help the victims of the Chūetsu offshore earthquake that struck the Niigata Prefecture. To raise funds for this charity, Gackt designed a keychain and bracelets, in addition, the charity also featured two Orico UPty MasterCard credit cards. Gackt's fan club Dears, raised ¥2,000,000 (US$26,041) which Gackt donated to the city of Jōetsu at the 83rd Kenshin Festival in 2008. On December 14, 2010 he participated in and performed in a Hohoemi project charity event called "Message! to Asia", by DATV at Tokyo Dome, whose profits were planned to help street children in Cambodia and the Philippines. For an auction at the event, he auctioned his custom 1999 Pontiac Firebird Trans Am MS6, which was sold for ¥6,015,000 (US$72,033). In 2011, because of the Tōhoku earthquake and tsunami, Gackt founded the "Show Your Heart" charity for collecting money to buy supplies for the victims. In March, a truck convoy with 72,000 lb (33,000 kg) of food and clothes was delivered and a nationwide street-corner fund-raising campaign was held, with Gackt's participation, which collected ¥25,234,490 (or US$320,193). All money collected through bank transfers and street fundraising activities was transferred from Rakuten to the Japanese Red Cross, totalling ¥208,181,735 (US$2,641,564). Part of the 2011 world tour and other activities of Gackt's band project Yellow Fried Chickenz revenue was also donated to the Japanese Red Cross. At several theatre plays of his Moon Saga: Mysteries of Yoshitsune I (2012), with the help of the Ashinaga (organization), orphans from the earthquake were invited and also received a monetary donation for scholarship. In addition to making a private donation, Gackt sold merchandise during the 2020 tour which raised ¥4.7 million (roughly US$44,000) to support the reconstruction of the recently burned-down Shuri Castle in Shuri, Okinawa.

Gackt is an ethnic Uchinanchu i.e. Ryukyuan. When he was young he experienced discrimination for it in Japan but it did not have a negative effect on him. He reportedly also experienced discrimination in a Paris hotel in 2015 for being Asian. His stated life and music goal is giving people hope, connecting them and uniting Asian countries. When he was 20 years old, Gackt was briefly married to a South Korean woman, and his "last big love affair" which ended in 2014 was reportedly with Japanese-born South Korean singer Lee Ahyumi. Gackt has lived for most of his life in Tokyo, Japan. In 2012 he moved to the Philippines and Hong Kong, with his primary residence located in Malaysia, where he has a mansion of 1,700 square meters situated in a residential area on the outskirts of Kuala Lumpur. In 2022 he was announced to be building and designing a new mansion in Malaysia. He also speaks Mandarin, Korean, English, and some French. He has a second-degree black belt rank in ITF taekwondo, as well as experience in other martial arts like karate, boxing, jiu-jitsu among others. In the past years he enjoys playing poker and since 2017 plays competitively on live tournaments, with largest cash of $75,600 from fourth-place finish in Aria High Roller, Las Vegas. He stated that his philosophical way of life is similar to Japanese Bushido. His personal religious belief is close to a nature god. His family believed that their deceased members became gods and they should venerate them, hence exist two conceptions of Ryukyuan religion in Okinawa whether to venerate the ancestors or nature. It does not have a well-defined theorization and rituals, but the practice is an acknowledgment of everything that surrounds people, "a love of nature". Gackt every year with his 20-30 staff members is cleaning his family Monchū tomb deep in the mountains of Southern Okinawa from where his ancestors originate, while the family altar in Northern Okinawa because his great-grandfather founded a town there.

In celebration of Gackt's 15th anniversary on July 1, 2015, the remix album titled, Gacktracks -Ultra DJ ReMix-, was released. It contained club remix versions of his songs done by Japanese DJs, including DJ Koo, Taku Takahashi, Tomoyuki Tanaka (FPM), Jazztronik, Marc Panther and many others. Gackt stated he personally would not decide to do the project from a musical perspective because he was not fond of EDM. He chose the DJs on a first-come, first-served basis, and, because of the great interest for participation, he believed in a second collaboration in the near future. He also expressed his concern on the decline of originality and growing irrelevance of music in modern daily life. On July 3 a release party was also held. On October 7, 2015 his forty-sixth single, "Arrow" was released. In the same month, he embarked on another small tour of cover concerts conceptualized around a fictional school, "Camui Gakuen", and with it performed on Hyde's band Vamps "Halloween Party" at Makuhari Messe, and on Niconico Super Party at the Saitama Super Arena. His solo live tour in almost seven years, Last Visualive Saigo no Tsuki –Last Moon–, started with a fanclub only concert on March 19, 2016 at Misato City Cultural Hall in Saitama, with the first public show being held on March 21 at the Colany Hall in Yamanashi. The tour ended on July 3 with two consecutive shows at the Saitama Super Arena. Overall, a total of 42 concerts in thirty cities were held, with an audience of about 120,000 people. There were planning talks about holding a world tour. The eighth studio album Last Moon was released on April 27, 2016. The 48th single "Tsumi no Keishō (Original Sin)" (罪の継承～Original Sin～; lit. "Inheritance of Sin: Original Sin"), conceptually related to the latest album, was released on March 22, 2017.

Gackt is known for his unique concerts, which he wants to preserve as works of art. His conceptual kind of concerts related to "Moon Saga" and "Requiem et Reminiscence" are different from typical music concerts neither they fit in the usual categories of a musical or a theatre play. Thus Gackt calls them "Visualive", because they are formed by a story, music, movies, theatre and musical elements, as well as live performance (with Gackt "acting" as the story protagonist). The shows are elaborately divided into two basic parts, conceptual and entertainment, which can be further divided into four parts, first has introduction concept movie followed by first set of concept songs, second has stage clothes change and second set of concept songs, third after a video of relief has a separate set of songs and MC with audience engaging in playful entertainment, and fourth has ending conceptual performance and closing movie. Reviewers described them as rock spectacles with a teartful story that will make the audience wish for a peaceful world. During the performance of "Rain" on 2002 and 2003 tours had the water drops falling like a rain from the ceiling onto the stage. His final performance of Diabolos tour in 2005 at Tokyo Dome (costing roughly $4.3 million) received praise and shocked the audience, as included entering the arena on a horseback in full gallop with four other horse riders, in a suspended coffin during "Lust for Blood", singing "Love Letter" hanging 20m in the air, and disappearing in a sudden smoke explosion. The 2008-09 Requiem et Reminiscence II and 2016 Last Visualive - Last Moon tour concerts lasted up to four hours. The Visualive concert format was originally created during the Requiem et Reminiscence tour in 2001, and according to Gackt, it took him almost ten years to arrive to a satisfying point of form during the Requiem et Reminiscence II tour in 2008-2009. However, he found such way of expression as difficult and physically and mentally exhausting, with a profitability that is not in accordance with the demands of entertainment industry. By 2007 he had a lot of requests to tour worldwide, but such large-scale shows are difficult to have in foreign countries and need significant logistical support for transportation.

In 2006, he continued his tour with a concert on January 14, in Korea, at Fencing Stadium in Korean Olympic Park, which was his first Asian solo concert. In the same month his twenty-fourth single, "Redemption" was released, which included theme songs "Redemption" and "Longing" of the Square Enix game, Dirge of Cerberus: Final Fantasy VII. On February 28, he appeared at the graduation of the Maiko High School in Hyōgo Prefecture. Besides the words of encouragement, he performed an unreleased song especially written for the graduation. It was released the following year on February 7, as "No ni Saku Hana no Yō ni". Since then he continued to appear in graduation ceremonies, with 16 performances by 2025. In August, at an Otakon conference, it was publicly announced that he would form a rock supergroup, S.K.I.N., with X Japan drummer Yoshiki, Luna Sea guitarist Sugizo, and guitarist Miyavi. The group had an ambitious vision to be the first Asian band to conquer the world charts. On December 24, Gackt went on a small nationwide fan club tour Training Days – Dears Reserved Unique Gackt (D.r.u.g./Drug) Party, which also continued with four concerts in Korea and Taiwan in January 2007. The tour, being his first livehouse tour since going solo, had a specific theme as while performing rock songs embraced an all-out androgynous style approach. On June 20, Gackt released his twenty-seventh single, "Returner (Yami no Shūen)", which was the first in his career (both solo and as a member of a band) to reach the number one spot on the Oricon charts. Its music and video were inspired by the NHK Taiga drama Fūrin Kazan in which Gackt played Uesugi Kenshin. The supergroup S.K.I.N. made debut performance on June 29, 2007 at Long Beach Arena, California, but no further activities were announced. On 10 October, he held a press conference at the Apple Store in Ginza, Tokyo, where besides advertising the first iPhone, Gackt announced he would have his entire back catalog, with new, previously toured, live song recordings, put up on the iTunes Store, as well as that "The Greatest Filmography" would be released on October 9 in the United States and Canada. His album Diabolos was released on October 26 in eighteen European countries. On November 17 and 27, he performed at M.net/Km Music Video Festival in Korea as a special guest star, and he appeared and performed at the 2007 Japan-China Cultural Exchange Grand Concert Final in Beijing where sang "Jūnigatsu no Love Song" in Japanese, Korean, and Mandarin. On December 19, Gackt released a compilation album, 0079–0088, including songs used in the Gundam franchise. Gackt also performed at the 58th Kōhaku Uta Gassen.
