Here's the twist: the band's signature tag, “Harajuku core,” isn't something they came up with themselves. By their account, they took it straight from words overseas listeners left in the comments.

This article follows them in order, from a girls' school music club to a U.S. tour, and on to one day in August 2026, when two support drummers stood in during Chika's hiatus. Channel figures are as measured by this site on November 1, 2026. Interview quotes from English-language media are given as published; quotes from Japanese sources are our translations.

Who Are HANABIE.'s Members? How to Say the Name, and Where the “。” Came From

According to Sony Music's official profile, the band has four members: Yukina (vocals), Matsuri (guitar and vocals), Hettsu (bass) and Chika (drums).

Chika's hiatus from band activities was announced on July 31, 2026. As of November 1, 2026, we could not find any announcement of her return in Sony Music's news (more on this below).

The profile lists Yukina, Matsuri and Hettsu as “Born in 1999” and Chika as “Born in 2000.” Yukina's entry includes “Screamer” and “Height 149cm”; Hettsu's includes “Fashion-monster” and “Heavy drinker.” And Chika's “Has matchless love for ice cream” has a charm all its own.

The word in the band's name, hanabie, is a seasonal term for a temporary return of chilly days in spring. According to Cocotame, Sony Music's own media site, it was chosen because Yukina was born in April and the other three members were born in winter. “Many (Japanese) bands have English names, so we should definitely have a name in Japanese,” Hettsu recalled. “And we chose the name that would stand out on flyers.”

The final “。” was Yukina's doing: filling out an application for something, she added it to the band name “without permission from the rest of the band (laughs).” She was copying another band that she and Hettsu were into at the time, so it seems to have been a pretty casual decision.

Overseas, the name often gets pronounced “ha-na-bee” instead of “ha-na-bee-eh.” In an interview with JRock News, Matsuri said the band had started letting fans know how it is pronounced.

A Band That Started in a Girls' School Hallway

It all began in the hallway of an all-girls school that runs from junior high through high school. According to an interview with TOKION, Yukina, who had already decided to join the high school's after-school music club, approached Matsuri, who was rumored to love heavy music. Matsuri used to bring her favorite band's towels to gym class, so her secret was out.

The band formed in June 2015. The Japanese version of the official profile describes them as “classmates who met in their high school's after-school music club” (translated from Japanese).

Matsuri was the only one who had played any instrument. Vocals turned out to be the last role left, and Yukina apparently volunteered for it herself. She taught herself to growl, too. On a 2023 radio show (in Japanese), Yukina said:

“We were originally a MAXIMUM THE HORMONE cover band back when we were students. That's when I practiced on my own.” (translated from Japanese)

Their seniors, though, reportedly told them to learn the basics first, so early on they covered bands such as ELLEGARDEN. The school didn't allow them to play shows off campus, so they got permission on condition that their parents came along, collecting signatures from everyone from their homeroom teacher up to the principal.

From then on, the place they kept going back to was Shinjuku ANTIKNOCK, a live house (small rock club) in Tokyo's Shinjuku. They'd rush over still in their school uniforms, then push one another over who had to be the first down the stairs past that dark entrance. It's such a high-school story that it's hard not to smile.

Who Came Up With “Harajuku Core”?

Their early look was the exact opposite of today's. To fit in with the metalcore bands around them, it was skinny black jeans and a white T. Yukina says she once even splattered red paint on a white T-shirt to make it look like blood. But they soon realized that just wasn't them. Around the time of “L.C.G.” in November 2019, they began putting the cuteness of the anime they love, and of Sanrio, front and center.

The turning point came while the pandemic had live shows on hold. In January 2021 they released the music video for “WE LOVE SWEETS” (我甘党), and English-language comments from overseas started piling up under it.

In the song, they scream their love of sweets in strawberry headgear, and it still has 4.42 million views. It was picked up in reaction videos by creators overseas, and Yukina says that made them start thinking about their overseas listeners.

The name “Harajuku core” also came from overseas listeners' comments. The interviews we read don't say which video they were posted under, or when. In the second part of the TOKION interview, Matsuri recalled listeners writing, “This is a new genre! It's HARAJUKU CORE!” HANABIE. is a hard band to explain, so Yukina's reaction was, “That's it!”

It's a little funny that what the official profile calls “their original genre, ‘Harajuku-core’” started out as something fans typed in the comments.

What Is HANABIE.'s Signature Song “Pardon Me, I Have To Go Now” About?

The most-viewed video on their channel is “Pardon Me, I Have To Go Now” (お先に失礼します。), released January 9, 2023. The Japanese title is a set phrase people say at work when they leave before their colleagues. It has 12.77 million views, far ahead of the No. 2 video, “Be the GAL~Early Summer ver.~,” at 4.84 million.

With a music video set in an office, it might look like a jab at a “black company,” the Japanese term for an exploitative employer. But Matsuri told JRock News that what they wanted to depict was the workplace greeting itself: “Rather than depicting a ‘black company’, we're simply showcasing the use of greetings like ‘Osaki Ni Shitsurei Shimasu’.” It seems the idea was to highlight a Japanese expression that, as Matsuri put it, doesn't exist “in many other cultures.”

On July 26 that same year, they made their major-label debut on Epic Records Japan with the album Reborn Superstar! (来世は偉人！).

A Revolving Drum Seat, and Chika's Arrival Two Months Before the Debut

HANABIE.'s drum seat has changed hands several times since the band formed. In November 2020, the official channel posted a video sending off Ruka, who had served as their support drummer for about two and a half years.

The big crunch came in 2023. According to Hettsu, the band's third drummer was set to leave in April, with their major-label debut due in July and overseas shows lined up after that. We could not find out, as far as we looked, why that drummer left.

Enter Chika, who had been playing in bands since junior high in Hamamatsu, Shizuoka Prefecture. The band she was in was nearly over and she was thinking about quitting when, she says, a teacher at her music school told her about HANABIE. It was her first band playing loud music, but she decided to join as soon as she got the offer. As she told Cocotame, “I thought it was my destiny.”

She joined at a show in Machida, Tokyo, on May 27, 2023. An official video posted the next day carries the line “The four of us will continue to make our activities more exciting!”

Touring Overseas, and Why They Keep Singing in Japanese

The month after their debut, they were already abroad: Europe in August 2023, then the U.S. from September. The festival in Slovenia that was supposed to open the European run was canceled because of heavy rain and flooding, EN.CORE ROCKS reported.

At a festival in the Netherlands, Yukina spotted a boy crying in the crowd. According to Metal Hammer, he was visiting from the U.S. and had talked his parents into a family trip so he could see HANABIE. play. He had been crying tears of joy.

Before long, they had come far enough that the Japanese version of the official profile lists “Lollapalooza” and “Wacken Open Air” among their appearances.

Even so, they don't seem inclined to tilt their lyrics toward English. In the second part of the Cocotame feature, Matsuri said, “I think we should properly sing in Japanese exactly because we now have more opportunities to perform overseas.” Stage banter is a different story, though: Hettsu has been trying to toast the audience in each country in its own language.

What Happened on the 2026 North American Tour

The “U.S. tour in March” that the Japanese version of the official profile mentions did take place. According to Live Nation's announcement, 21 shows were planned, from Boston on March 13 to Los Angeles in April.

Early on, though, they stumbled at the Brooklyn show. According to a local report, Yukina lost her voice, and after the start time was pushed back several times, the four of them came out on stage to announce that the set was canceled. The two support acts reportedly played in their place and carried the night.

The tour went on, and a JRock News report on the April 10 show in San Francisco wrote that any concern about Yukina's throat vanished once she stepped on stage.

Chika's Hiatus, and Three Cities in One Day

On August 2, 2026, they played the “Triple Scoop Tour 2026,” hitting three cities in a single day. Osaka at 9:45 a.m., Nagoya in the afternoon, Tokyo at night: a frankly reckless schedule.

In the video, Yukina reveals that the idea was “born while we were joking around, saying, ‘Should we just do it all in one day?!’” (translated from Japanese).

In fact, two days before the tour, on July 31, 2026, it had been officially announced that Chika “will be taking a hiatus from band activities for the time being due to health concerns, following medical advice.” So all three shows were played with support drummers. According to OTOTOY's official report (in Japanese) and the video description, Gaku Taura of Crystal Lake played drums in Osaka, and Ruka in Nagoya and Tokyo.

The notice says the band will “continue to support her so that she can return in the best possible condition,” and the description of the “Bari Bari Buddy” music video, published on October 14, 2026, still lists the lineup with “Dr. Chika.” As of November 1, 2026, we could not find any announcement of her return in Sony Music's news.

Taura is someone the band owes a great deal to: Matsuri told JRock News, “If we hadn't met Gaku-san, I don't think it would be the same ‘HANABIE.’” He also produced their early releases.

As for Ruka, a Natalie article (in Japanese) writes the name in katakana as ルカ, the same spelling as the 2020 support drummer. In the documentary video, Matsuri introduces “our support drummer, Ruka,” and Ruka says, “It's been seven years, huh.” It seems safe to say that the Ruka the band sent off in 2020 has come back.

At the final stop, Shinjuku ANTIKNOCK, Yukina looked back on the days when hardly anyone came to their shows. “Back then, there were so few people on the floor” that they once threw the stage riser down onto the floor and played from there, she said, and that day the same venue was packed.

Matsuri said, “If we do this when we're grandmas, I think it'll kill us,” but it seems she'd like to keep doing projects like this.

Next Up: Their Third Album, UMAMI

New releases are already on the calendar. According to the official announcement (in Japanese), “Bari Bari Buddy,” the ending theme for the TV anime I Reincarnated as a Sword II (転生したら剣でしたII), is scheduled for release as a single on November 4, 2026. The album UMAMI is scheduled for release on December 2; at the time of the September 13 announcement, the track list had not been decided. The nationwide 2MAMI TOUR 2026 is scheduled to run until December 12 at Zepp Shinjuku, where coldrain will share the bill on the final night.

The official YouTube channel has 350,000 subscribers, about 89.89 million total views, and 320 videos as shown on the channel page. As of November 1, they have posted 96 videos so far in 2026, and they keep putting out Shorts that document life between tour dates.

The high schoolers who once jostled at the top of those stairs are now a band that plays festivals around the world and still comes home to the same live house.
