Kenshi Yonezu’s Comment & Latest Artist Photo Revealed!
“In creating this song, I spent a lot of time diving into the script, but I also found myself turning to traditional nursery rhymes for inspiration. In particular, the songs ‘Tulips’ and ‘Antagata Dokosa’ (a traditional Japanese circle-game song) had a significant influence on me.
I believe that the passing down of traditions and connections between people, and where that ultimately leads, doesn’t necessarily require anyone’s approval or official validation. It’s something that people simply settle into and choose for themselves. The song is titled ‘Haru ga Tomori’ (The Light of Spring). I hope you enjoy it.”
Kenshi Yonezu Profile
After dominating the Vocaloid scene under the name “Hachi,” Kenshi Yonezu began releasing music under his real name in 2012.
In 2018, “Lemon” topped the Billboard Japan Year-End charts for two consecutive years, exceeding 3 million sales and setting the record for the most-viewed music video in Japan. “Paprika” became a social phenomenon among children across Japan, and his 2020 album STRAY SHEEP established a record with 2 million copies sold. “KICK BACK” achieved a historic feat as the first-ever Japanese-language song to earn Platinum certification from the Recording Industry Association of America (RIAA).
In 2025, “IRIS OUT” set numerous milestones—including the highest weekly stream count and the fastest song to reach 100 million streams in Japanese domestic history—while also achieving the highest-ever ranking for a Japanese-language song on global charts, continuing his streak of making music history.
Starting in November, he will hold his largest tour to date, “Kenshi Yonezu 2026 TOUR / GHOST,” performing across Japan and internationally.

First Look: The Apothecary Diaries Film Drops Thrilling Latest Trailer
Set to the sound of theme song “Haru ga Tomori,” the newly released trailer unveils the curtains on a top-tier mystery entertainment venture surrounding treasure hidden within a floating city.
Accompanied by intriguing lines like “If everything ends without ever knowing…” and “A lonely person,” the trailer begins with the bouncy piano melody of the theme song, hinting at the start of a new incident.
To return the remains of Ruo Qing—a middle-ranking consort who passed away five years ago—to her hometown, Maomao and Jinshi visit Binan-shu, a territory under the direct control of the Bi Clan. There, they encounter Yinshan, a former head court lady who served Ruo Qing, and Mu Qing, the youngest son of the Bi Clan.
Watching Yinshan offer kind words to protect Mu Qing—a concubine’s child shunned by the clan’s other children—Maomao receives the impression of a relationship almost like mother and child. However, the gentle atmosphere is short-lived. The mood turns ominous instantly with the appearance of Suija, a water pirate captain searching for treasure hidden by the deceased former leader.
Yinshan mutters “Why…” upon seeing Ruo Qing’s body; Muqing confesses that he was not a wanted child, exposing the secrets harbored by the clan; and the head of the corpse is stolen by someone unknown. The secrets surrounding Ruo Qing’s remains trigger multiple incidents, steering events in an unexpected direction. Set against the emotional melody of the theme song “Haru ga Tomori,” this trailer is a must-see for fans that raises anticipation for the film to an absolute high.
