Sakurazaka46: Reinventing an Idol Group

#Sakurazaka46 #JapaneseMusic #JPop

Japanese idol history is full of graduations, new generations, and changing concepts, but a complete change of name is far less common. Sakurazaka46 did not begin as an entirely new act assembled from unfamiliar faces. It emerged from Keyakizaka46, one of the most commercially successful and visually distinctive Japanese idol groups of its era, and carried many of the same members into a deliberately different chapter.

That history makes Sakurazaka46 more than another large J-pop group. It represents an ongoing experiment in artistic renewal, generational succession, and collective identity. In an industry where a famous brand can become both an advantage and a burden, how does a group respect what made it important while still earning the right to become something new?

From Keyakizaka46 to Sakurazaka46

The story begins in August 2015. According to Sakurazaka46’s official profile, 22,509 people applied for the audition that produced Keyakizaka46, the second group in the Sakamichi Series after Nogizaka46. Keyakizaka46 made its recording debut on 6 April 2016 with “Silent Majority.”

The single established the group’s public image immediately. Its serious atmosphere, confrontational message, and dramatic choreography distinguished Keyakizaka46 from many conventional idol debuts. The official profile states that “Silent Majority” achieved what was then the highest first-week sales total for a female artist’s debut single on the Oricon chart. [Official profile]

Keyakizaka46 appeared on NHK’s Kōhaku Uta Gassen only eight months after its debut and ultimately placed eight consecutive singles at number one on the Oricon weekly singles chart. Its performances depended on more than attractive costumes and synchronised movement. Songs, choreography, facial expressions, camera direction and the position of the centre were treated as parts of a single dramatic statement.

That approach gave the group a recognisable identity, but it also made change difficult. Audiences associated the Keyakizaka46 name strongly with a particular emotional intensity, performance structure and central figure.

In July 2020, during the streamed concert KEYAKIZAKA46 Live Online, but with YOU!, the group announced that Keyakizaka46 would end its activities after a final concert and restart under a new name. Its final concerts were held on 12 and 13 October 2020.

Sakurazaka46 officially began its activities on 14 October 2020. The new name had been revealed the previous month through the large screens near Shibuya Station. [Official profile]

The change was not presented as an attempt to pretend that Keyakizaka46 had never existed. The official website still maintains a Keyakizaka46 archive, while the members’ shared history remains essential to understanding the new group. However, the new name created space to redistribute attention, introduce different centres and develop a broader emotional and visual vocabulary.

A New Beginning with “Nobody’s fault”

Sakurazaka46 released its first single, “Nobody’s fault,” on 9 December 2020, with second-generation member Hikaru Morita as centre. The title suited a group emerging from a period of uncertainty and significant change: firm, defiant and forward-looking.

The sound and staging retained some of the sharpness audiences expected from the members’ previous work, but the presentation did not simply reproduce the Keyakizaka46 formula.

The early Sakurazaka46 system included the “Sakura Eight,” the eight members placed in the first two rows of the main formation. These members also appeared across the single’s coupling songs. Later formations evolved beyond that particular system.

This development mattered because Sakurazaka46 gradually became less dependent on one permanent central figure. Different members could carry different musical concepts, allowing the group to maintain a recognisable performance standard without becoming visually or emotionally static.

Hikaru Morita became one of the principal faces of the early Sakurazaka46 period, centring “Nobody’s fault” and “BAN.” Karin Fujiyoshi, Ten Yamasaki, Hono Tamura, Rena Moriya and members of the newer generations subsequently received title-track centre positions.

Each performer brought a different quality. Fujiyoshi became associated with controlled dramatic intensity, Yamasaki with expansive physical presence, Tamura with mature force and Moriya with a softer form of elegance. This rotating-centre approach became one of Sakurazaka46’s defining strengths.

Music, Movement and Contrast

Sakurazaka46 is generally classified as J-pop and as a Japanese idol group, but those labels do not fully explain how its music functions. Many of its title tracks are designed as complete performance pieces. Their impact depends on rhythm, formation changes, gestures, expressions, costumes, and visual storytelling as much as on the recorded melodies.

“BAN,” released in 2021, used urgent electronic production and forceful choreography to reinforce a theme of resisting social dismissal. “Nagaredama” pushed the group towards a louder and more aggressive presentation, while “Samidare yo” demonstrated a more lyrical and restrained side.

“Sakurazuki,” released in 2023, placed greater emphasis on melancholy and elegance. “Start over!” then returned to a restless and rebellious energy with Karin Fujiyoshi at the centre.

The contrast between these songs is important. Sakurazaka46’s development cannot simply be described as the group becoming lighter than Keyakizaka46. It still uses darkness, tension, frustration and defiance, but it has expanded the range of emotions surrounding those elements.

A Sakurazaka46 concert can move from severe theatricality to tenderness, humour or direct communication with the audience. The members are therefore not confined to repeating one expression of resistance.

The 2024 single “何歳の頃に戻りたいのか？” (“Nansai no Koro ni Modoritai no ka?”), “自業自得” (“Jigou Jitoku”) and “I want tomorrow to come” further demonstrated the group’s changing centres and concepts.

Third-generation member Shizuki Yamashita received her first title-track centre position with “自業自得” and returned as centre for “I want tomorrow to come.” Billboard Japan’s reporting on the latter confirmed its 23 October 2024 release and highlighted Yamashita in the principal visual. [Billboard Japan]

In 2025, the group released “UDAGAWA GENERATION,” “Make or Break” and “Unhappy birthday構文,” as well as its second album, Addiction, on 30 April.

Mio Matono became the centre of “Make or Break,” while Yu Murai received her first Sakurazaka46 title-track centre with “Unhappy birthday構文.” The official formation archive documents the participating members and positions for these releases. [Official formation archive]

The group continued its release schedule in 2026 with “The growing up train,” issued on 11 March, and the double A-side “Lonesome rabbit / What’s ‘KAZOKU’?”, issued on 10 June.

“The growing up train” returned Karin Fujiyoshi to the title-track centre and brought fourth-generation members into the selected line-up. The fourth-generation song “光源” (“Kougen”) was centred by Konomi Asai, giving the new generation a distinct showcase rather than using its members only as background additions. [Billboard Japan; official formation archive]

Both title tracks on “Lonesome rabbit / What’s ‘KAZOKU’?” were centred by Hikaru Morita. The release was the first double A-side single issued by a Sakamichi Series group. According to Billboard Japan, it sold 683,481 physical copies during its first chart week and reached number one on Billboard Japan’s Top Singles Sales chart. [Billboard Japan]

The 16th Single: “愛MUST BE”

Sakurazaka46’s 16th single, “愛MUST BE,” is scheduled for release on 14 October 2026. Third-generation member Airi Taniguchi holds the centre position, marking her first time centring a Sakurazaka46 title track.

The selected formation contains 16 members. The front row consists of Hono Tamura, Airi Taniguchi, and fourth-generation member Ui Yamakawa, with Taniguchi occupying the central position.

Reina Odakura centres the BACKS song “自称バレエダンサー.” According to the official announcement, the TYPE-D artwork is composed of the BACKS members, while Airi Taniguchi appears on the TYPE-A cover as the title-track centre. [Official release announcement; Billboard Japan]

The single is being released in four limited CD and Blu-ray editions and one regular CD-only edition. Seven original songs are distributed across the different versions:

• “愛MUST BE”
• “元凶”
• “自称バレエダンサー”
• “アベセン”
• “1mmも飛ばない鳥”
• “あの日の私で”
• “I’m the law”

Because this article was updated on 6 October 2026, “愛MUST BE” must be treated as a forthcoming release. Its confirmed formation, songs, and release date can be reported, but no first-week sales or completed chart results should be attributed to it yet.

Generations and the Transfer of Identity

Large Japanese idol groups are designed to change. Members graduate, new auditions are held, and the group name survives beyond any particular line-up. In practice, however, replacing experience and public recognition is never automatic.

The transition must feel credible to established fans while giving newer members enough space to become more than substitutes for their predecessors.

Sakurazaka46 inherited first- and second-generation members from the Keyakizaka46 period. The third generation was introduced in 2023 and quickly became central to the group’s next phase.

Members such as Shizuki Yamashita, Yu Murai, Mio Matono, Airi Taniguchi and Yuzuki Nakashima gradually received visible formation positions, centre opportunities and generation-specific performances.

Their emergence changed the central question surrounding Sakurazaka46. Instead of asking whether the group could survive its rebranding, audiences could begin asking how its identity would continue after the members who experienced the original 2015 launch had departed.

The fourth generation added another layer of renewal. By 2026, Konomi Asai, Neo Sato, Chihiro Nakagawa and Ui Yamakawa had entered selected title-track formations.

Fourth-generation songs and concerts also created space for the cohort to establish its chemistry independently. The official formation records show how Sakurazaka46 alternates between selected title-track line-ups, generation songs, unit tracks and BACKS performances. [Official formation archive]

The BACKS structure gives members outside a single’s main selected formation their own song and performance opportunities. BACKS concerts can create alternative centre positions and allow members to demonstrate development.

The system makes the group’s internal hierarchy visible, which can be emotionally difficult for members and fans. However, it also creates identifiable opportunities for performers who are not selected for a particular title track.

Current Sakurazaka46 Members

As of 6 October 2026, Sakurazaka46’s active roster consists of 30 members across the second, third and fourth generations.

This list is based on the official participant roster for the 16th-single events. The main alphabetical directory is less reliable for determining current status because archived profiles of some graduated members can continue to appear in its search results. [Official 16th-single event roster]

Momomi Yamada is a fourth-generation member active in the cohort’s music and live-performance development. She has participated in the generation’s dedicated songs and the group’s 16th single activities.

The fourth generation consists of nine members. Its development has been unusually visible through dedicated music, fourth-generation concerts, and the gradual inclusion of members in Sakurazaka46’s main selected formations.

Captain Rina Matsuda and Group Leadership

Captain Rina Matsuda has been important to Sakurazaka46’s generational transition. She succeeded Yūka Sugai as captain in November 2022, when the leadership position was transferred during Sakurazaka46’s first Tokyo Dome concert under its current name.

Matsuda’s position combines public communication, group cohesion, and continuity between generations. Sakurazaka46’s performance identity may be intense, but its offstage and variety-show image often depends on warmth, quick reactions, and the ability to present members as distinct individuals rather than anonymous parts of a formation.

Concerts Built Around Performance

Live performance is one of the clearest ways to understand Sakurazaka46. The choreography frequently uses the entire formation to frame, obstruct, carry, or confront the centre. Individual members may disappear into the larger group before emerging for a brief expressive moment.

This technique makes the collective formation part of the storytelling. The centre is not simply the person standing in the middle. She becomes the focal character inside a larger physical composition.

The group held its first Tokyo Dome concerts under the Sakurazaka46 name in November 2022. In June 2024, it returned for two additional Tokyo Dome performances as part of the 4th ARENA TOUR 2024 Shin Sakurazensen – Go on back?

According to the official concert report published by Billboard Japan, the two dates drew a combined audience of 110,000, including fans who travelled from outside Japan. [Billboard Japan]

The programme connected several phases of Sakurazaka46, from “Nobody’s fault” to the live debut of “自業自得,” while also placing the third generation inside the group’s central concert narrative.

These concerts demonstrate why judging Sakurazaka46 only through its audio recordings misses an essential part of its appeal. Its songs are designed for bodies moving through space. Lighting, costume, staging, facial expression, and formation changes give the lyrics and music additional meaning.

The group held its 5th ANNIVERSARY LIVE at MUFG Stadium, Japan’s National Stadium, on 11 and 12 April 2026. Moving from the uncertain restart of 2020 to a two-day anniversary event at that venue illustrated the scale achieved by the Sakurazaka46 name in its own right. [Official site]

Building an International Audience

Sakurazaka46’s fans are known as “Buddies,” a name taken from a coupling song included with the group’s debut single.

The term has become particularly useful internationally because it gives overseas followers a shared identity without requiring detailed knowledge of Japanese idol terminology.

Sakurazaka46 performed at Japan Expo Paris and Japan Expo Malaysia in 2023. The group also received the Popularity Award in the female singer category and the Best Musician Award at the 2023 Asia Artist Awards in the Philippines.

Billboard Japan reported that the popularity award was determined through voting by fans around the world. [Billboard Japan]

In July 2025, Sakurazaka46 made its first performance appearance in the United States at Anime Expo in Los Angeles. The official announcement connected the appearance to J-POP SOUND CAPSULE @AX2025 and a collaboration involving HUNTER×HUNTER. [Official site]

These appearances do not transform Sakurazaka46 into a conventionally globalised pop act, and Japan remains its principal market. Nevertheless, they show that the group’s visually direct and choreography-driven performance style can communicate beyond Japan even when international spectators do not understand every lyric.

Television and the Members Beyond the Stage

The weekly TV Tokyo variety programme Soko Magattara, Sakurazaka? has aired since October 2020. It succeeded the Keyakizaka46 programme Keyakitte, Kakenai?

The programme performs a different function from the group’s music videos and concerts. Onstage, members may appear severe, mysterious, or emotionally overwhelmed. In variety content, they can appear competitive, awkward, witty, relaxed, or unpredictable.

That contrast is central to the Japanese idol model. Audiences are encouraged to follow personal development rather than consume only finished musical performances.

Member blogs, meet-and-greet events, variety shows and the official Sakurazaka Channel allow individual personalities to emerge outside the group’s dramatic musical identity. For international viewers, official online video content has become an important point of access, although language availability can still restrict wider engagement.

Controversies, Rumours and Misinformation

Sakurazaka46 has experienced relatively few publicly confirmed cases of member misconduct under its current name. The group’s most widely documented controversy occurred during the earlier Keyakizaka46 era, while several other supposed “scandals” remain based on anonymous claims, tabloid reporting, or fan interpretation.

Separating confirmed events from unsupported allegations is particularly important when discussing an idol group whose members are exposed to constant online observation.

The 2016 Costume Controversy

The most clearly documented controversy connected to the group’s history occurred in October 2016, during the Keyakizaka46 period.

At a Halloween performance held on 22 October, the members wore black military-style costumes featuring long coats, capes and peaked caps. The clothing was criticised for resembling uniforms associated with Nazi Germany and the Waffen-SS.

The Simon Wiesenthal Center, a human-rights organisation focused on Holocaust remembrance and antisemitism, publicly condemned the costumes and called on Sony Music and producer Yasushi Akimoto to apologise.

Sony Music Japan subsequently issued an apology, acknowledging insufficient historical understanding during the creation of the costumes. The company stated that it had not intended to associate the performance with Nazism and promised that the costumes would not be used again. Yasushi Akimoto also apologised for failing to provide adequate supervision. [Associated Press; Simon Wiesenthal Center reporting]

The controversy is therefore real and documented. However, it must be identified as a Keyakizaka46-era incident from 2016 rather than something that happened under the Sakurazaka46 name.

There is no reliable evidence that the young performers personally designed the costumes or endorsed Nazi ideology. The production side accepted responsibility, as it controlled the event’s costume and presentation decisions.

Allegations of Internal Bullying

Reports and online speculation have alleged internal conflict and bullying during the Keyakizaka46 period. Some of these stories were later linked to member departures, formation decisions, or visible changes in relationships.

However, no public official finding or sufficiently documented independent evidence has confirmed these allegations as an organised bullying campaign.

Much of the available material relies on unnamed sources, tabloid narratives and fan interpretations of television footage or member behaviour. That does not prove that every interpersonal problem was invented, but it is not enough to identify supposed perpetrators or present a coordinated bullying narrative as fact.

The responsible conclusion is that allegations circulated, but they remain unverified. Naming members as bullies without stronger evidence would be both unfair and potentially defamatory.

Dating and Relationship Rumours

Claims about secret relationships, members disliking each other, or management imposing hidden punishments must be evaluated individually.

An anonymous post, edited video clip, unusual facial expression, or change in formation position is not sufficient evidence of a relationship, argument, or disciplinary action. Idol fandoms frequently construct narratives from incomplete public information, particularly when a member misses an event or receives fewer performance opportunities.

Some former idols may discuss relationships after leaving their groups, but later disclosures do not automatically verify every rumour circulated during their membership.

For Sakurazaka46, there is no reliable basis for presenting online claims about current members’ private relationships or supposed internal hostility as confirmed scandals.

Stalking and Intrusive Fan Behaviour

The most clearly documented recent problems have involved conduct directed at the members rather than wrongdoing by them.

In May 2024, Sakurazaka46’s management issued an official notice asking people to stop following members, their relatives and staff. The statement said that incidents had occurred near offices, television stations, concert venues, recording facilities, photography locations, and rehearsal studios.

Management also stated that information about vehicles and individuals involved had been provided to the police. [Official Sakurazaka46 statement]

This represents a genuine safety issue. It should not be described as a member scandal because the members were the targets of the behaviour.

The notice also demonstrates why invasive fan actions cannot be excused as ordinary enthusiasm. Following performers into private or work-related spaces can cause fear, disrupt professional activities, and require police involvement.

Defamation and False Online Claims

In March 2025, Seed & Flower established a dedicated reporting channel for potentially illegal posts involving Sakurazaka46.

Management explained that members and staff had encountered defamatory posts, insults, threats and claims that were not based on facts. The official statement specifically referred to cases in which unverified rumours were collected and redistributed as though their truth had already been established. [Official Sakurazaka46 statement]

Seed & Flower stated that it had consulted legal advisers and pursued requests to identify anonymous posters. Courts had granted disclosure orders in multiple cases. Management also warned that particularly serious cases could result in civil compensation claims or criminal complaints.

These announcements confirm that false or potentially unlawful posts were a significant enough problem to require a formal reporting system and legal action.

However, the statement did not identify every rumour involved. It therefore cannot be used to declare all criticism or every negative report about the group false. Each allegation still needs to be evaluated according to its evidence.

The warning also applied to people who amplify defamatory content. Reposting, quoting or otherwise spreading an unsupported allegation can increase the harm even when the person sharing it did not originate the claim.

What Can Honestly Be Concluded?

Based on publicly available official statements and reliable reporting, no major pattern of confirmed member misconduct has been established under the Sakurazaka46 name.

The most substantial confirmed controversy connected to the group’s history remains the 2016 Keyakizaka46 costume incident, for which Sony Music and producer Yasushi Akimoto apologised.

Claims involving bullying, dating, management punishment or internal hostility should remain classified as unverified unless reliable new evidence becomes available. The most clearly documented recent problems have involved stalking, intrusive fan behaviour, harassment and defamatory rumours directed at the members.

This distinction matters. Responsible entertainment reporting should neither protect public figures from legitimate criticism nor turn unsupported online speculation into permanent accusations.

Why Sakurazaka46 Matters

Sakurazaka46 matters because its success was not guaranteed by the strength of the Keyakizaka46 name.

A famous past can attract attention, but it can also freeze expectations. If the renamed group had copied its predecessor too closely, the transformation would have appeared cosmetic. If it had abandoned every recognisable quality, it could have alienated the audience that followed the members through the change.

Instead, Sakurazaka46 retained its seriousness of performance while distributing responsibility across more centres, more generations and a wider range of emotions.

The group created a catalogue in which aggressive songs, reflective material and brighter fan-oriented moments can coexist. Its identity now lies less in one irreplaceable member or one permanent mood and more in its ability to make changing formations feel dramatically purposeful.

There are still genuine challenges. Every graduation removes experience, each new generation must establish public recognition, and international visibility remains modest compared with the group’s domestic scale.

The selection and BACKS systems can also make differences in opportunity highly visible. Nevertheless, Sakurazaka46’s history demonstrates that instability can become part of an artistic identity rather than merely a threat to it.

From “Nobody’s fault” to the album Addiction, the introduction of the fourth generation and the forthcoming “愛MUST BE,” Sakurazaka46 has turned reinvention into a continuing process.

It is not simply Keyakizaka46 under a different name, nor is it disconnected from the group that came before. Sakurazaka46 exists in the space between memory and renewal—and that tension remains the source of some of its most compelling performances.
