The theme song for the upcoming BL drama series "Kimi wa Natsu no Naka" has been decided: Masaharu Fukuyama's love ballad "Hotaru" underscores the story of the two high school students Wataru Toda and Chiharu Saeki. The official trailer, which presents the new remix of the song, was released on June 19, 2026.
"Hotaru" originally appeared in 2010 as the theme song for another drama series and was specially remixed for "Kimi wa Natsu no Naka." The producers chose the song because the lyrics about precious time with a loved one perfectly match the relationship of the main characters and the atmospheric summer sonata of the series. Fukuyama himself expressed delight at the request: "I am surprised and happy that my song from 2010 receives this honor. I hope that the newly remixed version of 'Hotaru' can accompany the feelings of Wataru and Chiharu in this summer of 2026."
The drama series is based on the manga of the same name by Nagisa Furuya ("Kimi wa Natsu no Naka," "Kimi to Natsu no Naka," published by Ichijinsha). It tells the tender love story between the unassuming high school student Wataru Toda (played by Tomoya Oku) and the popular but reserved classmate Chiharu Saeki (Kazuto Mokudai). The two are connected by a passion for films – from their shared hobby, a deeper affection soon develops.
The trailer was shot with an 8mm film camera, giving the images a grainy but refreshing aesthetic. It shows summer scenes and the sensitive moments between the protagonists. At the same time, the team released first scene photos from the first episode: In them, Wataru is asked by a female classmate to find out who Chiharu loves – but the friend's answer completely surprises him.
"Kimi wa Natsu no Naka" premieres on July 1, 2026 at 12:30 AM on TV Tokyo and other channels. A week earlier, on June 24, the series starts exclusively on the streaming platform U-NEXT. The further cast includes Shujiro Yoshimura, Seidai Hirakawa, Ren Komai, Shuto Imai, and Hiroto Oshita. The screenplay is by Yo Saito, direction is by Kozue Sasaki and Shun Haga. The music was composed by Erina Koyama.
