Snow Man's Sakuma Daisuke takes center stage in a new behind-the-scenes documentary for his starring film role. The special footage, titled "Movie 'Specials' Dance Documentary ~That Summer, The Journey Until We Could Dance~," dropped on YouTube this week.

The documentary offers fans an intimate look at the rehearsal process behind the dance sequences in "Specials," Sakuma's latest acting project. For international fans, Sakuma is known as one of Snow Man's main dancers and has been expanding into solo acting work alongside the group's activities.

Snow Man, part of Johnny & Associates (now SMILE-UP.), has seen several members branch into individual projects while maintaining their group commitments. The nine-member group debuted in 2020 and quickly became one of Japan's top idol acts.

The documentary's title hints at an intensive summer rehearsal period, suggesting the dance sequences required significant preparation. This type of behind-the-scenes content has become increasingly popular with J-Pop idol films, giving fans insight into the dedication required for these crossover projects.

While "Specials" marks another step in Sakuma's acting career, Snow Man continues their music activities. The group regularly balances individual member projects with collective releases, a common approach in the Japanese idol industry that allows artists to explore different creative outlets while maintaining their group identity.
