Nami no Oto

Morning sand, salt left behind, a distant train. In this AI music video, Hikari walks back to a shore that no longer feels like home, carried by the sound of the waves.

"Nami no Oto" is an original song by Hagane Sakura 鋼の桜, blending Japanese acoustic pop-rock with a nostalgic 2000s J-pop feeling, crisp steel-string guitar, warm live drums, melodic bass and subtle clean electric textures.

The song is about returning to a place that no longer truly feels like home, and realizing that some memories remain even after the people, words and reasons for staying have disappeared.

This time, Hikari carries the song alone. Her voice begins close and intimate over the acoustic guitar, almost as if she were speaking quietly to the shoreline.
