This film is particularly sought after by collectors due to its artistic innovation and historical significance. In 2015, Hara returned to the forefront with *SOAR: I Wish You Were Here*, a film that showcases his ability to blend various media, including animation and live performance. This unique approach to storytelling has attracted a dedicated following among collectors who appreciate the artistic depth and technical skill found in his works. Hara’s films are not only collector's items for their rarity but also for their rich contributions to the evolution of Japanese cinema.
