Springmaker Films has announced the release of ONE OF ONE, a feature-length documentary uncovering the story of Naito Auto Engineering, a family-run restoration shop in Tokyo that has quietly become one of Japan’s best-kept secrets. The film premieres September 1, 2025, on Amazon Prime Video, Apple TV+, Google Play and Vudu.
Founded in the aftermath of WWII by Shinichi Naito, a self-taught mechanic who once worked on bomber planes, the workshop has thrived under the leadership of his son Masao, who transformed it into an internationally renowned destination for classic car restoration. From Porsches and Ferraris to Lotus and Alfa Romeos, the Naito family has built its reputation on meticulous craftsmanship and an unshakable dedication to detail.
Directed by first-time filmmaker Ben Bertucci, the 85-minute documentary combines new footage from Tokyo’s backstreets and expressways with the family’s archival film and photographs. It explores Masao’s looming retirement and the question of whether the next generation can preserve both the artistry and unity of the family legacy.
Alongside the film, a limited-edition companion book was created and is available for pre-order now. The 250-page hardcover expands the story through unseen workshop moments and Bertucci’s raw, intimate photography, offering readers a deeper look into the Naitos’ generational journey.
