Kenshi Yonezu's Lemon Reaches One Billion YouTube Views, a First for a Japanese Language Music Video

A milestone eight years after the video's release

Kenshi Yonezu's Lemon passed one billion YouTube views at 11:08 p.m. on November 3, 2026, becoming the first music video for a song sung in Japanese to reach that figure, according to the artist's official announcement. Directed by Tomokazu Yamada, the video was published on February 27, 2018.

The official milestone announcement, published on Yonezu's website on November 4, puts the journey at approximately eight years and 249 days. The achievement brings a new record to a song that topped Japan's annual charts, became a karaoke staple and helped turn its creator into one of the country's leading musicians.

Yonezu responded with something more complicated than a celebration. The singer and songwriter credited the TBS drama Unnatural, for which he wrote Lemon, while describing his bewilderment at watching the song become much bigger than he had imagined.

In his statement, Yonezu said he still struggled to understand the scale of its success:

In all honesty, I still don't really get why 'Lemon' became such a huge song with this wide a reach.

His response, alongside messages from Unnatural star Satomi Ishihara, screenwriter Akiko Nogi and director Ayuko Tsukahara, gives the milestone a human dimension. For Yonezu, Lemon became a signature song almost before he could process what was happening. For the people who made the drama, it remains tied to particular scenes, friendships and memories.

A song about loss with a personal starting point

Lemon was written for Unnatural, broadcast in 2018, and deals with the grief of losing someone important. Yonezu's grandfather died while he was working on the song, an experience that helped shape its treatment of death and enduring affection.

The recording pairs a melancholy melody with a driving rhythm and a distinctive vocal sample. Those musical details give the song movement even as its subject remains painful. Listeners encounter a pop song that carries sorrow without standing still.

Yonezu also gave substantial credit to the drama's production team. In his statement, he said Lemon's reach grew from its association with a television series he admired and from the care with which the team used it.

The relationship went in both directions. Tsukahara's response describes the song feeding into the drama's images, while Ishihara and Nogi describe how hearing it still brings back emotions from that period. Lemon became part of how they remember making Unnatural, as well as part of how audiences remember watching it.

Success was already measurable in 2018 and 2019

Lemon's billion views follow years of success across several different ways of listening. It was Billboard Japan's Song of the Year in 2018 and again in 2019, making Yonezu the first act to take that annual honor with the same song in consecutive years.

In September 2019, downloads passed three million. By the end of that year, the music video had accumulated more than 495 million YouTube views, already close to half of the new milestone.

Those figures show how much of Lemon's audience arrived early, and how much listening continued afterward. The video accumulated roughly another half a billion views between the end of 2019 and November 2026. Its reach extended well beyond the original television broadcast and the first wave of attention.

The song also connected several kinds of music consumption. At the end of 2018, it led four measures used in Billboard Japan's Hot 100 calculations: downloads, video views, Twitter mentions and lookups, which counted occasions when a CD was copied to a computer. Its success spread across purchases, online viewing and public conversation.

Karaoke made Lemon a song people performed themselves

Lemon held first place on the Oricon weekly karaoke ranking for a record 85 consecutive weeks. That amounts to more than a year and seven months during which it remained the leading song on that chart.

It also topped Billboard Japan's karaoke list for 49 consecutive weeks after that measure was introduced. The two runs belong to different rankings, each with its own measurement period.

Karaoke adds another dimension to the viewing record. A YouTube play records someone watching or listening; a karaoke performance involves someone choosing to sing the song. Lemon became a piece that listeners repeatedly made part of their own gatherings and routines.

Yonezu brought the song to a major television audience at the end of 2018. For his first televised singing performance, on the 69th NHK Kohaku Uta Gassen, he appeared by live broadcast from the Otsuka Museum of Art in his home prefecture of Tokushima. The performance placed his breakthrough song at the center of one of Japan's biggest annual music programs.

Yonezu describes a hit that escaped his expectations

Yonezu recalled being astonished by the speed at which Lemon's reputation spread after release. He had expected to make a worthwhile song, but the public response quickly exceeded his own sense of its place in his work.

In his statement, the songwriter compared the experience to starting a small campfire and watching it grow into a wildfire:

It was like lighting a small scrap of wood on fire, thinking I'd start a campfire, only to have the flames spread instantly and eventually turn into a full-blown wildfire with me just standing there holding a lighter in one hand and a bucket of water in the other.

Yonezu connected that experience with musicians he had watched while growing up. He once found it difficult to understand why an artist might seem distant from a beloved signature song or reluctant to perform it. Lemon helped him understand the discomfort of having one work become the public's defining image of its creator.

His description centers on the speed at which listeners give a song meanings of their own. The creator's original intentions become only one part of its life. Ishihara's and Nogi's statements illustrate that process: the same recording carries different memories for each of them.

Yonezu nevertheless made his gratitude explicit. In a follow-up message on X, he thanked listeners again and said he had not had enough time to revise the original statement, which he felt had turned out rough and less celebratory than intended.

Satomi Ishihara remembers an old guitar

Satomi Ishihara, the star of Unnatural, attached her congratulations to a specific memory from the production's closing party. Late in the evening, Yonezu came after enthusiastic requests from the group and performed Lemon on an old guitar that was out of tune.

Ishihara said the occasion combined the satisfaction of completing the drama, the happiness of the party and her birthday. She described it as a day that marked a turning point in her life and said she would never forget the performance.

Eight years later, hearing Lemon still brings back the excitement and happiness of that period, she said. Her message connects the huge viewing total to the private experiences behind it: individual people hearing the song at particular moments in their lives.

That recollection also shows the distance between Lemon's public scale and its personal meaning. A video can reach one billion plays while a single informal performance, on an imperfect instrument, remains the version someone treasures most.

The drama's creators hear their own memories

Akiko Nogi, who wrote Unnatural, described Lemon's journey from a theme song commissioned for the drama to a song shared by audiences much more widely. She also said it retained the power to awaken intensely personal memories.

For Nogi, hearing it unexpectedly can bring back feelings she does not necessarily want to revisit, yet does not want to lose. Her account gives a concrete explanation for repeated listening: a familiar song can preserve an emotional connection that someone wants to keep close.

Ayuko Tsukahara, the drama's director, described a different creative connection. Lemon supplied inspiration that went beyond the usual role of a theme song and became part of the images she created for Unnatural.

Tsukahara said that even now, hearing the song brings the drama's characters, including Mikoto, Shoji and Nakado, back into her imagination. She congratulated Yonezu on reaching so many people and expressed hope that they could work together again.

Yonezu credited the production with helping Lemon reach listeners. Tsukahara credited the music with shaping the production itself. Their statements describe a collaboration in which the television drama and its theme song strengthened each other.

The dates behind the billion views

Lemon's history stretches from its original video release to a new concert video and another tour. The main dates show how the song has remained present through successive stages of Yonezu's career:

• February 27, 2018: The music video directed by Tomokazu Yamada was published.
• December 2018: Lemon finished as Billboard Japan's Song of the Year, and Yonezu performed it on NHK's Kohaku Uta Gassen.
• September 2019: Downloads passed three million.
• End of 2019: The video had more than 495 million views, and Lemon secured a second consecutive annual song title.
• November 3, 2026, at 11:08 p.m.: The video crossed one billion views.
• November 4, 2026, at 8 p.m.: A performance of Lemon from the 2025 TOUR / JUNK concert at Tokyo Dome was scheduled to premiere on Yonezu's official YouTube channel.
• November 6, 2026: Yonezu's 2026 TOUR / GHOST was scheduled to begin.

Fans also noticed a numerical coincidence. Counting the publication date inclusively, they described the interval to the milestone as eight years, eight months and eight days. The repeated eights recalled Hachi, Yonezu's former name as a Vocaloid producer. Hachi means eight in Japanese.

Vocaloid is software that lets creators make a synthesized voice sing lyrics and melodies. Yonezu's earlier work under that name gives the number pattern a particular appeal for listeners who followed him before Lemon.

A signature song within a wider career

Yonezu's career had already expanded beyond Lemon by 2019. His arena tour that year drew 170,000 people, while concerts in Shanghai and Taipei marked his first performances outside Japan.

Other work reached audiences through different settings. He wrote Spirits of the Sea for the animated film Children of the Sea, and Uma to Shika became closely associated with Japan's 2019 Rugby World Cup campaign after beginning as the theme for a drama about a rugby team.

He also wrote and produced music for other performers, including Masaki Suda's Machigaisagashi and the children's group Foorin's Paprika. Those projects help explain why Yonezu's reflections concern the place of one enormous hit within a much broader body of work.

The billion views celebration arrived just before another period of touring. Following the scheduled November 6 opening of GHOST, international dates were planned from December in cities including Taipei, Seoul, Los Angeles, London and Paris. The Tokyo Dome performance video offered a new presentation of Lemon as Yonezu prepared to return to the stage.
