Mikio Fujioka

The band came up with the album title “Metal Resistance” because they believed it represents who they are and what they do as Babymetal. Su-metal said that “it’s about them exploring new, different aspects of what they can do.”

On April 1, 2019, Babymetal announced, via Twitter, that they would be releasing their third album later that year. On May 10, 2019, the band released the single "Elevator Girl". On May 29, 2019, it was announced that Babymetal will perform at the Glastonbury Festival in England on June 30, making them the first Japanese band to play on one of the festival's main stages. Babymetal also revealed plans for their first arena concert in the United States at The Forum in Los Angeles, CA, set for October 11, 2019. This was later revealed to coincide with the release of the band's third album Metal Galaxy with its featured song "Da Da Dance". It was featured on NPR's "best new albums of the week" the week of its release. On July 1, 2019, Babymetal released a new single from the upcoming album and a video entitled "PA PA YA!!", featuring F.HERO. The video, shot at one of their shows in Yokohama, also includes touring member Kano Fujihira, one of three girls currently rotating in Yui's place - Kano Fujihira, Riho Sayashi and Momoko Okazaki - who are known as the "Avengers".

In October 2019, the band became the first Asian act to reach the peak of Billboard Top Rock Albums Chart.

Tristan Peterson, of Metal Obsession, remarked in his review of the band's debut album "This band was created for the demographic of “Music that your Japanese Boyfriend/Girlfriend, who doesn’t really like Metal, would enjoy.” as well as "[Babymetal] has made metal cute without losing any of its edge."

In regards to their music video for the song “Karate", Moametal said that she’s “very proud that they are now representing this culture that came from Japan through their music, and it’s a way for more people outside of Japan to also learn what karate is all about.” The lyrics talk about never giving up and moving forward. Yuimetal stated that the choreography for the song represented the lyrics and that “it’s important to be able to express the messages that they want to put across through the music with their dance moves.” The majority of their lyrics are in Japanese and they see their choreography as a way to break the language barrier.

Babymetal is credited for creating the kawaii metal (“cute metal” in English) genre, which combines elements from J-pop and heavy metal. This genre has introduced metal to new audiences, and many new kawaii metal bands such as Doll$Boxx and Deadlift Lolita have formed since Babymetal’s debut. While most kawaii metal bands are based in Japan, the genre has begun to spread outside the country to places like South Korea, where kawaii metal bands like Pritz have formed. Furthermore, the reach of Babymetal’s influence has stretched far beyond Japan. In 2016 Babymetal became the highest-charting Japanese band ever in the UK’s Official Charts history with the release of their album Metal Resistance. In the US, Metal Resistance was the first Japanese album to chart in the Billboard Top 40 in over 50 years, where it reached #39 in its first week. The last Japanese artist to break the Top 40 was Kyu Sakamoto in 1963. In 2019 Babymetal became the first Asian act to top the Billboard Rock Albums chart with the release of their third studio album Metal Galaxy.

Yuzo Kayama, a famous musician, actor and songwriter in Japan, said of the song "Gimme Chocolate!!", “I think it’s hard to sing, but the pitch of the song is accurate. The rhythm is new, there are some Japanese points, the dance is innovative, and it’s crisp.” Reiko Yukawa, a well-known music critic in Japan, stated, “Babymetal is pretty cute with singing and dancing, they have charisma like Himiko, and glittering that no one can replace."

The Los Angeles Times stated, "Babymetal is a Japanese concept group, and they’re the most divisive thing in heavy music right now." MetalSucks stated, "Babymetal isn’t metal. It’s theater, the Japanese pop industry deconstructing post-millennial metal and modern pop tropes and reconstituting them into a fully realized, 360-degree entertainment experience." After Judas Priest's Rob Halford performed with Babymetal in July 2016, he stated, "Babymetal is the future of metal."

On October 19, 2018, Babymetal announced that Yui Mizuno (Yuimetal) had decided to leave the band due to poor health, following her absence from live performances since December 2017. Since her departure, the band has performed with one or more backup dancers at live performances. In 2019, the band introduced three backup dancers called Avengers who performed in rotation at each live show to form a trio with Moametal and Su-metal.

On April 1, 2018, Babymetal posted a mysterious video entitled "Metal Resistance Episode VII – The Revelation" on their YouTube channel. In the video, it is explained that a "dark side" of Babymetal exists, "with seven metal spirits", and that a "new era is about to begin". On May 1, they announced via Twitter that they were launching their own record label, named Babymetal Records. One day later, they posted another cryptic message via Twitter and Instagram, stating that "no one will know who, when, where, or how, the Chosen Seven will be presented, only the Fox God knows." Over the next week, they posted a series of cryptic images onto their Instagram story, labelled 1-7, and displaying mysterious, black and white imagery in anticipation of the tour and the Chosen Seven.

On May 8, 2018, just ahead of the Babymetal World Tour 2018, the band released a music video for a new single, "Distortion". Yuimetal was absent from Babymetal's tour of the United States in May 2018, with no advance warning. Amid fan speculation on Mizuno's status with the group, a representative of 5B Management, the American management company representing Babymetal, replied to an inquiry from Alternative Press Magazine by saying that "Yuimetal remains a member of the band, but she is not on this current U.S. tour." The reply also hinted about "a new narrative for the future of the band which is currently evolving" and a "storyline" that "has changed." However, Yuimetal was also absent from Babymetal's European tour in June 2018, and her appearance for the Asian leg remained unconfirmed. Babymetal has since performed at Rock on the Range in Columbus, Ohio, the Download Festival in Donington Park, United Kingdom, and the Rock am Ring and Rock im Park festivals in Germany.

On July 9, 2018, the band won the champion of Heavy Metal World Cup 2018.

On October 19, 2018, shortly before the Japan leg of the tour, the band released a new single, "Starlight". On the same day, the band officially announced Yuimetal's departure from the group. Mizuno has since released a statement explaining her decision and her desire to pursue a solo career.

On October 30, 2018, the Apocrypha: The Legend of Babymetal graphic novel was released by Z2 Comics, with story by "The Prophet of the Fox God" and art by GMB Chomichuk. The story presented the legend of the Three as they traveled through different time periods to combat evil.

During the 2018 World Tour, due to Yuimetal's absence, the band performed with Moametal and Su-metal in front of one another, using risers to separate, while two backup dancers perform at the sides of the stage. Since her official departure, the traditional triangle formation has been restored, with a non-singing backup dancer performing in Yuimetal's place.

In January 2017, Babymetal supported Metallica for their WorldWired Tour at Gocheok Sky Dome and also appeared in Japan's performance of the Guns N' Roses' Not in This Lifetime... Tour as the opening act. In April 2017, Babymetal supported the Red Hot Chili Peppers during The Getaway World Tour in the US. In June 2017, Babymetal performed at the KISW Pain in the Grass music event in Auburn, Washington. During the summer of 2017, they supported Korn on their Serenity of Summer Tour. Afterwards, they commenced their The Five Fox Festival in Japan tour.

In October 2017, Babymetal were officially revealed as the performers of the "Unikitty Theme" for the Unikitty! TV series. On December 2 and December 3, 2017, Babymetal performed at the Hiroshima Green Arena, with the shows billed Legend "S" Baptism XX. This was the first time the group performed in Su-Metal's hometown of Hiroshima, and it was an early coming of age celebration for her, since December 20, 2017 was her 20th birthday (as hinted in the show title), the age of majority in Japan; the lyrics to "Headbangeeeeerrrrr!!!!", about a girl's fifteenth birthday, were even modified for the occasion. This was also Babymetal's first performance without all three members, as Yuimetal was unable to perform due to illness.

On December 30, 2017, Kami Band guitarist Mikio Fujioka fell from an observation deck; he died from his injuries on January 5, 2018.

The band was formed in 2010, with the original lineup of Su-metal (Vocal and Dance), Moametal (Scream and Dance), and Yui Mizuno as "Yuimetal" (Scream and Dance), with the concept of creating a fusion of the heavy metal and Japanese idol genres. Originally a sub-unit of the Japanese idol group Sakura Gakuin, Babymetal became an independent act in 2013, following Nakamoto's departure from Sakura Gakuin. Babymetal released their eponymous debut album in February 2014. Their second album Metal Resistance was released worldwide on April 1, 2016 (2016-04-01 ) . Babymetal has also embarked on several tours, with a majority of their tour dates taking place outside of Asia.

During the band's headlining shows at Yokohama Arena in December 2015, announced a second studio album to be released on April 1, 2016, as well as a world tour starting in London at the Wembley Arena, and concluding in Japan with a debut at the Tokyo Dome. On January 15, 2016, the second album's title was revealed to be Metal Resistance.

On March 13, the band's producer, Kobametal, received an Excellence Award from the Association of Media in Digital (AMD) in Japan for his success in promoting the band internationally. On April 2, one day after the release of Metal Resistance, Babymetal became the first Japanese act to headline Wembley Arena, with the largest sale of merchandise for a single day event in the venue's history, coinciding with the highest ever entry for an album in the UK charts for a Japanese act. The Guardian gave their Wembley performance a rating of five out of five stars. On April 5, Babymetal made their U.S. television debut, performing "Gimme Chocolate!!" on The Late Show with Stephen Colbert. Babymetal were added as a character skin in the Wii U video game Super Mario Maker in 2016.

On May 26, 2016, WWE's Triple H announced on Twitter that Babymetal's song "Karate", along with A Day to Remember's "Paranoia", would be used as official theme songs of NXT TakeOver: The End. On July 18, the band made a special appearance at the Alternative Press Music Awards where they performed "Karate" before being joined onstage by Judas Priest frontman Rob Halford. Halford, along with Nakamoto and the Kami Band, performed an abridged version of "Painkiller", followed by a performance of "Breaking the Law" where they were rejoined by Mizuno and Kikuchi on guitars. On July 27, Metal Hammer readers voted Babymetal's debut album as the best album of the 21st century. In September 2016, Warner Bros. announced that a hybrid live action-animation fantasy-adventure short form series featuring the members of the band was under development. The series would be developed by Blue Ribbon Content in collaboration with Amuse Group USA (an Amuse Inc. subsidiary based in the United States). The band's producer, Kobametal, is also involved with production of the series.

On September 19 (Red Night) and September 20, 2016 (Black Night), Babymetal ended their Babymetal World Tour 2016: Legend Metal Resistance by performing at the Tokyo Dome, with both nights sold out and approximately 55,000 people attending each night. These included fans from Japan and many others from around the world. Yuimetal admitted she was "still in shock" that she was playing at the venue. Moametal felt the same, calling it "a big challenge for young girls of our age to stand on that stage". Su-metal explained that "In Japan we have played many big venues like Budokan and others, but Tokyo Dome was always a place that I have been dreaming of performing at." In December 2016, Babymetal supported the Red Hot Chili Peppers during The Getaway World Tour in the UK. During their final show on the tour, Red Hot Chili Peppers drummer Chad Smith joined Babymetal onstage to perform their covers of Judas Priest's "Painkiller" and "Breaking the Law". After the performance, Smith thanked Babymetal for being on tour with them and led the audience in singing "Happy Birthday" to Su-metal.

In August 2014, it was announced that the band would return to England to play another show at London's O2 Academy Brixton on November 8, their final European show of the year as part of the group's "Babymetal Apocalypse" phase. It was later announced that the band would also return to New York City, which they had visited earlier in the year without giving an actual performance, performing at the Hammerstein Ballroom on November 4. At their Brixton performance, the band debuted a new song titled "Road of Resistance." Later revealed to be a collaboration with Sam Totman and Herman Li of prominent power metal band DragonForce, the song was subsequently released as a bonus track of their first live album Live at Budokan: Red Night, released simultaneously along with the band's third live video album Live at Budokan: Red Night & Black Night Apocalypse on January 7, 2015, and later released as a digital single. Li later revealed via Twitter and Facebook posts that he and Totman had been working on the song's guitar parts since 2013. In 2015, they re-released their eponymous album via earMusic and RAL/Sony Music Entertainment. Ahead of their performance at the Metal Hammer Golden Gods Awards on June 15, the trio made a surprise appearance during DragonForce's set at Download Festival, performing "Gimme Chocolate!!", despite event organizer Andy Copping stating that he would never book the band.

On February 26, 2014, Babymetal released its first, eponymous album. It contained thirteen tracks and was also available in a limited edition that included a DVD with music videos and live footage. The album was well received by music critics as well as the public, selling over 37,000 copies in Japan its first week, debuting at number four on the Oricon Weekly Album Chart, and number two in Billboard Japan. It also topped iTunes Metal charts in Germany, the United Kingdom and the United States, and reached number 187 on the US Billboard 200 chart on March 22. Their album also made it into the Heatseekers chart at number four. On March 1 and 2, 2014, the band gave two concerts at Budokan. With the average age of 14.7, they became youngest-ever female act to perform a show there. The two concerts were attended by 20,000 people. On April 3, 2014, an episode of the Fine Brothers' YouTubers React show was uploaded to YouTube, covering the band and the music videos of "Doki Doki Morning", "Iine!", and "Gimme Chocolate!!"; the band members' own reaction to the video would later be released on April 30, 2016.

Later in 2014, Babymetal embarked on their first world tour, the Babymetal World Tour 2014, performing in Paris, Cologne, and in the United Kingdom at the Sonisphere Festival 2014. They made their debut appearance in the United States on July 27 with a headlining show at The Fonda Theatre in Hollywood. They played Heavy Montréal 2014 in Canada on August 9 alongside Metallica and Slayer, and also performed at Summer Sonic 2014 in Japan on the Mountain Stage with bands such as Avenged Sevenfold and Megadeth. Babymetal was also the opening act to five of Lady Gaga's concerts in her "ArtRave: The Artpop Ball" 2014 tour in August along the western United States. Babymetal also released their second live album Live: Legend 1999 & 1997 Apocalypse on October 19, 2014, featuring their live performances at both the NHK Hall and at Makuhari Messe Event Hall from 2013.

Patrick St. Michel from Japanese music and culture site MTV 81 praises the "pure, headbang-inducing energy" of the group's live performances and describes their style as a mixture of "...seemingly disparate sounds of heavy metal and idol pop, creating music anchored both by throat-mauling screeches and cuddly choruses." The magazine Metal Hammer described their act using the formula "Short skirts, school girl charm and squeaky voices — just like in the manga comics. But they mix the whole thing with Metal."

In their concerts, Babymetal are accompanied by a backing band. In their early stages, the backing band consisted of the "Babybones"—a group of nameless individuals dressed in skeleton costumes that would mime live performances while pre-recorded studio tracks were being used. In late 2012, Babymetal debuted a live band for their live performances which they referred to as "Full Metal Band" - a group of live musicians dressed in white robes and corpse paint. They have since been referred to by band members and fans as "Gods of Metal" and more recently "Kami Band". From late 2012 to early 2014, the two groups would alternate, with the Kami Band being used more for festival appearances and special events. At the Babymetal Death Match Tour in May 2013, the Kami Band performed all music live for the first time. As of early 2014, the Babybones band has been quietly retired, and the Kami Band has since been established as Babymetal's primary backing band.

Babymetal's music videos, which showcase their distinct visual aesthetic, have helped the band gain broad attention. Their video for "Gimme Chocolate!!" went viral in 2014 with USA Today's Brian Mansfield commenting that the "video looks like some kind of bizarre animé, with a dark-goth set and band members playing in skeleton costumes, and the three girls execute intricate choreography, flash heart signs and make windmill arm motions like they're playing air guitar"

On January 9, 2013, the band debuted on a major record label with "Ijime, Dame, Zettai". Released under the main Toy's Factory label and Juonbu Records, it sold 19,000 copies in its first week and debuted at number six in the Oricon Weekly Singles Chart. In the spring of 2013, Nakamoto graduated from junior high school and therefore had to "graduate" from Sakura Gakuin (a group of elementary and junior high school girls). However, their management decided that Babymetal would not dissolve and would continue its activities as a band. The group released its next single, "Megitsune", on June 19, 2013, under Toy's Factory and the band's new sublabel BMD Fox Records.

On August 10 and 11, 2013, Babymetal again took part in the Summer Sonic Festival, performing in Tokyo and Osaka. Later, in October, Babymetal also became the youngest artists ever to perform at the heavy metal music festival Loud Park. In November, Babymetal released a promo video for the Japanese premiere of Metallica's movie Through the Never, and released its first live music video Live: Legend I, D, Z Apocalypse, which debuted at seventh place in the weekly Oricon Blu-ray Disc charts, and at second place among music Blu-rays. In December, Babymetal performed overseas at Anime Festival Asia Indonesia 2013, and performed for a second time in Singapore.

On December 10, 2013, Babymetal released "Babymetal Apocalypse", an incomplete binder that would be gradually filled with pages intermittently made available later. Pages would include the lore of Babymetal, artwork and photos, and information on member-exclusive events, like "Apocrypha" during the Babymetal World Tour 2014. By purchasing the binder and entering a code included with the enclosed art book online, one could join the band's official fanclub called "Babymetal Apocalypse Web". A video uploaded to "Babymetal Apocalypse Web" members in December 2014 announced the transition to a new official fanclub called "The One", which started with limited edition releases for Live at Budokan: Red Night & Black Night Apocalypse, and would continue to release member-exclusive media with news published to the official fansite.

Babymetal's first CD single was a collaboration with the band Kiba of Akiba, titled "Babymetal / Kiba of Akiba". Released in March 2012 by Juonbu Records, the single ranked at number three on the Oricon weekly indie chart, and number one in the Tower Records Shibuya weekly indie ranking. In the summer of 2012, the band released a music video for their next single, "Headbangeeeeerrrrr!!!!!", directed by Hidenobu Tanabe. In August 2012, Babymetal debuted at Japan's Summer Sonic Festival, becoming the youngest act ever to perform at the festival, at the average age of 12. The same year, Babymetal performed outside of Japan for the first time, Anime Festival Asia 2012, in Singapore.

The Kami Band has consisted of a rotating line-up of different musicians since its debut in late 2012. As of early 2018, however, the line-up has been relatively stable, consisting of guitarists Takayoshi Ohmura, Leda, and Isao, bassist Boh, and drummers Hideki Aoyama and Yuya Maeta with members occasionally substituting for one another if needed. Kami Band member Leda has contributed to Babymetal's music, most notably on their album Metal Resistance (credited as Ledametal).

Babymetal's first live appearance was on November 28, 2010 (2010-11-28 ) , at Sakura Gakuin's first solo concert, Sakura Gakuin Festival ☆ 2010. In July 2011, Babymetal premiered the song, "Ijime, Dame, Zettai" ("No More Bullying"), at a Sakura Gakuin concert, but it would only be performed during live concerts for the time being. The band's first single, "Doki Doki Morning", originally appeared on Sakura Gakuin's debut album Sakura Gakuin 2010 Nendo: Message, released on April 27, 2011 (2011-04-27 ) . A music video for the song was uploaded to Toy's Factory channel on YouTube on 12 October 2011, and was released as a DVD single in late 2011, under the independent Toy's Factory sublabel Juonbu Records. The music video totaled over 1 million views by the end of 2012.

Kobametal, the band's producer and long-time heavy metal enthusiast, started planning to launch an idol/heavy metal fusion group in 2009 after he was impressed by Suzuka Nakamoto's performance with her previous group, Karen Girl's, thinking she was suitable to be the lead vocalist for the new group. The band was formed in 2010 in Tokyo, Japan, as the heavy music club (重音部 , Jūonbu) , or sub-unit, of the female idol group Sakura Gakuin, which was also newly formed that year. According to Kobametal, Yui Mizuno and Moa Kikuchi were added to complement Nakamoto's "unique stage presence" with their then small statures, dancing around her "like angels". None of the three members were familiar with metal music before the inception of the band.
