In an emotional collaboration that transcends the screen, the King & Prince‘ member and the promising young actor star in “#春うたベスト50,” a campaign that explores family ties and the healing power of music in the spring of 2026.

Spring in Japan is not only a season of climate change, but also a period of life transitions and new beginnings. With this in mind, Universal Music has launched its eagerly awaited annual campaign, “#春うたベスト50” (The 50 Best Spring Songs), focusing its narrative on a story of brotherly reconciliation starring two figures from different generations: Ren Nagase (King & Prince) and young actor Soya Kurokawa.
This year’s campaign is not limited to a simple playlist. Through a series of four short commercials, the first of which, titled “Brothers’ Stories: Conflict,” premiered on March 12, we are introduced to the lives of the Tsukishima brothers. The plot introduces us to Yutaka (played by Ren), a fourth-year university student who, after facing successive failures in his attempt to succeed in music, decides to give up and accept a corporate job. On the other hand, Megumu (Soya Kurokawa), his younger brother in his last year of high school, feels betrayed. For Megumu, the promise to “make music together” was the driving force in his life, and seeing his idol give up on his dreams leads him into a personal crisis that pushes him to want to drop out of school.
The narrative uses Yorushika‘s songs, known for their emotional depth, to underscore the tension and nostalgia of this reunion in the family home. It is in this setting of “conflict” that the music of spring acts as the only bridge capable of bridging the gap that years and disappointments have opened between them.

Despite this being their first project together, the chemistry between Ren and Soya has surprised both the production team and fans alike. In a recent exclusive interview after filming, Ren praised his younger co-star’s maturity: “Soya has a very stable presence for someone his age. He doesn’t seem like a freshman in high school.” However, between laughs, He couldn’t help but reveal a small weakness of the young actor: his difficulty waking up in the mornings. “I found out that his mother still has to help him get up,” he said amusedly, to which Soya shyly replied, “Please don’t tell anyone!” These kinds of natural interactions helped build the bond of brotherhood that the campaign sought to project.
Soya, for his part, confessed to being thrilled to work with someone he admired on television. “I was surprised to have him in front of me. He was very kind, asking me what music I listened to and what my school life was like,” explained the actor, who recalled that his own high school graduation was marked by pandemic restrictions, which made him appreciate even more the theme of human connection addressed in the ad.
Playlists that Tell Personal Stories
As a central part of the “春うたベスト50” experience, Universal Music has made a series of playlists personally selected by the protagonists available on various streaming platforms (Spotify, Apple Music, YouTube, among others). Ren‘s selection reflects a more reflective tone, ideal for those facing the end of a work or academic stage meanwhile Soya‘s selection is focused on the energy of youth and the songs he often sings at karaoke with his friends, providing a vibrant and hopeful vision.
These playlists include not only current hits, but also classics that evoke the bittersweet feeling of Japanese spring. The campaign’s official website also allows users to explore the profiles of the characters, Yutaka and Megumu, delving deeper into the story of “reunion and regeneration” that will unfold in the next three installments of the commercial series.
Beyond promoting music, both artists agree that family is at the heart of this project. Ren reflected on his own relationship with his younger brother in real life, mentioning that “communication is sometimes difficult due to their busy schedules, but that small gestures, such as giving him clothes he no longer wears, keep that bond alive. “ I hope this commercial will motivate people to express their gratitude to their loved ones before the graduation season ends,” he said. Soya closed the presentation with a message of encouragement for his peers: “Spring brings many changes to our environment. I hope that by watching this story and listening to these songs, people can take a step forward with a more positive mindset.”
With the promise of three more chapters to come, the 2026 “#春うたベスト50” campaign is shaping up to be not only a commercial success, but a necessary reminder that even as seasons change and dreams transform, music and family remain our strongest anchors.
