Daichi Hirosawa, born February 14 under the Aquarius sign, began his career as a construction worker before joining the original Shōnen Hollywood. His designated green Hollywood Color mirrored his earthy practicality. As an idol, he dreamed of constructing a grander Hollywood Tokyo theater, envisioning himself as its architect. The group disbanded abruptly less than a year after their president’s unexpected passing, despite soaring popularity. Post-idol life saw Daichi return to construction, his steadfast pragmatism unchanged.

Now a stage carpenter specializing in set design, he maintains deep ties to Hollywood Tokyo. His mentorship of the new Shōnen Hollywood generation includes guiding Kira Saeki, a member plagued by self-doubt. Daichi encourages Kira to find strength in authenticity, advocating for sincerity over flashiness—advice that helps Kira accept his own unassuming nature.

His surname, Hirosawa, blends “wide” and “marsh,” while his given name, meaning “big earth,” reflects both his grounded persona and past profession. A stage play adaptation later portrayed his legacy, with actor Kazumi Doi embodying his role, though further spin-off or media engagements remain unrecorded.
