A Royal Evolution: Celebrating the 8th Anniversary of King & Prince

A Legacy of Radiance: 8 Years with King & Prince

On 23 May 2018, the J-Pop scene was changed forever. It marks eight years since six young men (almost teenagers) crossed the threshold of their debut with “Cinderella Girl,” instantly becoming the heirs to a crown that promised to shine for decades. Today, as they (and we too!) celebrate their eighth anniversary, the story of King & Prince reads very differently from how we imagined it back then, but their brilliance is more intense than ever; it has been a chronicle of courage, transformation, and an unbreakable bond with their fans; Tiara.

From the overwhelming energy of their early years as a sextet, through the challenges of becoming a quintet, to the bold and historic transition into the duo now led by Ren Nagase and Kaito Takahashi, King & Prince has proven that a name is not just a brand, but a vow. This eighth anniversary does not merely celebrate chart-topping hits or tours of the country’s most important domes; it honors the maturity of two artists who chose to keep the flame alive when the winds blew hardest.

Today, we trace the journey of the “Cinderellas” who became kings of their own destiny, and are witnesses to how their evolution has redefined the meaning of loyalty and artistry in the modern Idol era.

The discography of King & Prince is, at its core, a story of artistic emancipation. When they debuted in 2018 with “Cinderella Girl,” they didn’t just release a hit; they established a visual and sonic standard that seemed immovable. They were the “Princes of the Reiwa Era”: orchestral strings, sweet vocal harmonies, and impeccable pop that recalled the golden age of Idols. During their early years, their music was a sanctuary of optimism and idealized romance. However, the group soon began to display a creative restlessness that pulled them away from the glass castles.

The first major sonic “earthquake” arrived with “Mazy Night,” where heavy synths and a much more aggressive rhythm began to erode their purely angelic image. But it was the collaboration with American R&B legend Babyface on “Namae Oshiete“ that confirmed King & Prince was seeking global respect. It was no longer just about being “idols“; it was about being musicians capable of navigating groove and soul with sophistication.

The climax of this transformation was felt in “Magic Touch“ and “Ichiban.” Here, the group embraced hip-hop not as an accessory, but as a primary language. The complexity of their choreography—demanding body control worthy of elite professional dancers—transformed their identity. They left behind the neatness of the waltz to master street dance. With their current transition as a duo, “moooove!!“ represents absolute freedom: a breezy funk/urban sound where Ren and Kaito flow with astonishing naturalness, proving that the crown isn’t worn on the clothes, but in the attitude and versatility.

Over the past eight years, Ren and Kaito have demonstrated that their talent knows no bounds, dominating cinema screens, television, and the covers of fashion magazines across Japan. The duo’s success is therefore not confined to the music scene but spans a wide range of audiovisual genres, with their multifaceted artistic talents shining through in every new project that emerges from their busy schedules. Their presence is a constant in Japanese daily life, and what makes this duo exceptional is their ability to separate their “idol” identity from their roles as prestigious actors and style icons, attracting an audience that extends far beyond the traditional fandom.

Ren has established himself as one of the most respected actors of his generation. His transition from youthful roles to complex dramas has been meteoric, highlighting his capacity for acting “metamorphosis“. From his award-winning role in Yowamushi Pedal (winning Best New Actor at the Japan Academy Film Prizes) to global Netflix hits like Drawing Closer, Ren has demonstrated astonishing interpretative maturity. His latest film, “Oni no hanayome“, is proving a huge hit at the box office, whilst critics are once again praising her ability to adapt to all kinds of roles and share the screen with the industry’s biggest names. As a model, Ren has collaborated with various brands, notably Dior, which has awarded him the title of “Friend of the House“, and Universal Music (the record label to which King & Prince belong), although he has previously worked with other Japanese brands such as Ken-ei Pharmaceutical, for which he has been the commercial face of several of their products.

Meanwhile, Kaito is the creative and multi-talented heart of the group. Even before his debut, he was already a nationally competitive dancer, a skill that today defines the technical complexity of the duo’s choreography. Kaito has broken the mould by becoming the first artist from his agency to officially debut as a mangaka (manga artist, whose work was serialised in Betsucomi magazine).

In his acting career, he stands out for choosing characters with great psychological depth and emotional nuance, establishing himself as an actor of great sensitivity. Among his most popular roles on the small and big screen are “Daga, Jounetsu wa Aru” (for which he won the Best Actor award at the 116th Drama Academy Awards) and his latest leading role in the films “Kimi no Kao de wa Nakenai” and his appearance in the film: “Ōi, Oui“.

In addition to his work as a professional dancer and actor, Kaito has been exploring his role as a designer in collaboration with the Italian luxury and haute couture brand ETRO. Since his first collaboration in 2024, Kaito has continued to travel back and forth between Japan and Milan every year; he even produced and launched his own capsule collection, “#ETROperKaitoTakahashi”, which was a huge success in the country’s boutiques, with some items even selling out. He has also been the face of the Korean skincare brand Torriden in Japan and the well-known udon chain Marugame Udon, with its popular “Udonuts” product.

The 8th Anniversary Milestone: Conquering the Streaming World

Historically, accessing music from artists under some Japanese labels was a privilege almost exclusive to the Japanese physical market. However, King & Prince became the spearhead of a necessary revolution. Their embrace of social media was not just a marketing move, but an act of musical democratization that allowed Tiaras worldwide to connect with them in real-time!

The group’s success on platforms like YouTube and TikTok has been overwhelming. On YouTube, their videos not only rack up millions of views but have served to showcase facets that traditional television formats did not allow: from their impressive Dance Practice videos —essential for understanding the technicality of tracks like “Magic Touch“— to intimate live streams that break the barrier between idol and fan. On TikTok, songs like “Theater“ or “SPOTLIGHT“ have sparked global trends, proving that their music possesses a universal language that transcends linguistics.

And although we were already able to enjoy their new music releases on multiple streaming platforms, as well as their compilation album “Mr 5” released to mark their 5th anniversary, Ren and Kaito have chosen the perfect gift for their Tiaras to mark the 8th anniversary of their debut; announced a few weeks ago during a live stream on YouTube, they revealed that all the group’s songs (singles, B-sides, etc.), from both their 6-member and 5-member eras, would also be made available to anyone wishing to experience the emotions that King & Prince have always evoked in us, regardless of the number of members in the group.

This heartfelt gift not only ensures the preservation of their legacy but also positions Ren and Kaito as global artists. By releasing a further 78 tracks from their catalogue catalogue, King & Prince cease to be a local phenomenon and become a soundtrack available to the whole world, ensuring that their reign is, at last, truly universal.

“Tiara” Moments: A Journey Through Memory and Heart

To speak of King & Prince’s eight years is, inevitably, to speak of the history of their fans. The name “Tiara,” proposed by Genki Iwahashi (but it is Ren and Kaito who have given it a new meaning of unity and unconditional support) during their debut event, was not just a label; it was a promise that the group and their audience would always walk together under the same light. This timeline is not merely a list of events, but a map of shared emotions.

The journey began with a surprise press conference on January 17, 2018 at the Universal Music building in Tokyo to announce the CD debut of the 6-member group King & Prince, then the presentation of their first single “Cinderella Girl,” at the “King & Prince Event” held at Roppongi Hills Arena on March 15, 2018 and the “First Concert Tour 2018,” a tour that solidified the phenomenon.

Seeing the Yokohama Arena illuminated by six different colors for the first time is a memory many Tiaras cherish as a treasure. That tour did not just celebrate the success of their first single; it established the majestic aesthetic that would define their early years. With the release of their self-titled first album in 2019, the group proved they were much more than a one-hit wonder, offering a vocal variety that promised a brilliant future.

Over the years, their concerts became milestones of resilience. From “L&” (2020), which had to be held online due to the pandemic but managed to unite the world through screens, the spectacular “Mr.” First Dome Tour (2022), where they fulfilled the dream of filling Japan’s largest venues for the first time, to “The Continuity Statement” (May 2023): A bittersweet yet crucial moment, when Ren and Kaito vowed to uphold the name of King & Prince, a gesture that strengthened their bond with Tiara.

Each of these events has been marked by closing speeches filled with honesty. King & Prince’s messages of gratitude have never been empty phrases; they have been confessions of vulnerability and strength, where Ren and Kaito have reiterated that “as long as there is one Tiara listening, King & Prince will continue to exist.” This May 23rd, looking back, we don’t just see records; we see a family that has learned to shine even in the longest of nights.

As we look back and trace these eight years of history, it becomes evident that King & Prince is not a group content with living off past glories or the echo of what once was. In an industry as ephemeral and demanding as J-Pop, achieving nearly a decade of relevance is not just a matter of talent; it is a testament to an almost unprecedented capacity for metamorphosis. What began as a classic fairytale in 2018 has evolved into a much more complex, real, and ultimately inspiring narrative.

Ren and Kaito have not just inherited a name; they have taken up the scepter with a maturity that transcends their chronological age. They have had to navigate the most difficult transition of their careers under intense public scrutiny, and they have done so with an integrity that has fortified the brand’s foundations. Far from being intimidated, they have honored every step of the group’s history, integrating its legacy into a new vision where high-fashion, prestigious acting, digital avant-garde, and sonic experimentation converge into a unique and unmistakable style.

Today, King & Prince is the reflection of a perfect balance: Ren‘s sophistication and Kaito’s overflowing creativity. Together, they have proven that the essence of the group did not reside in a specific number of members, but in a spirit of excellence and an unbreakable connection with their audience. They have transformed the concept of “Idol” into that of a “Complete Artist,” capable of topping music charts while conquering the runways of Milan or Japan’s most important cinema screens.

For Tiara, the fandom that has supported every step of this journey, these eight years are not the end of a path, but the prologue to a much more ambitious era. Ren and Kaito‘s promise is clear: to keep evolving without losing the light that made them shine from day one. With their eyes fixed on the horizon and renewed confidence, King & Prince continue to prove to the world that as long as there is passion on stage and loyalty in the stands, the glow of their crown is not only eternal —it shines with a new, blinding intensity every year. The reign has only just begun.
