Sora no Oto: Journey Through the Universe with Hayato Sumino Screening in Yokohama

A journey through “sound and the universe,” led by piano

At the heart of the production is music from “Human Universe,” an album Hayato Sumino created around the connections between music, the universe and the human heart. Piano melodies that are both delicate and powerful are paired with images of space, creating a world where stars and music seem to resonate together. The program explores the relationship between the universe and sound through the imagery and music unique to a planetarium.

The official introduction highlights the resonance between invisible sound waves and the universe. Blending scientific and philosophical perspectives, the production takes audiences on a journey to explore the origins of sound. More than simply gazing at the stars, this program offers time to reflect on the universe and music.

Voice actor Natsuki Hanae narrates the production, guiding a story told through piano and visuals with a voice that is both clear and powerful. Hanae is known for roles including Tanjiro Kamado in “Demon Slayer: Kimetsu no Yaiba.” The official page also features his comments on narrating the production. He says he hopes visitors will enjoy a chance to spend time in the otherworldly setting of the planetarium and reflect on the universe and music.

For more background on Sumino’s musical career, his official profile also mentions “Human Universe,” released in 2024. The album won the Classic Album of the Year award at the Japan Gold Disc Awards. Learning about the music’s background before your visit is one way to enjoy the screening.

The production page also notes that an “English audio guide [is] available.” Check the official schedule for your visit date to confirm screening times, and look for information about the audio guide if needed.
