Enhancing the beauty of Nikko Toshogu Shrine, a World Heritage Site, is lacquer, a natural material closely associated with Japanese culture. Lacquerer Noritake Sato uses his expertise to preserve the shrine's brilliance. We follow him as he attempts to restore part of the Honden, or Main Hall. One corner of the supporting structure is exceptionally damaged, and Sato's careful research hints at the difficulties encountered by his predecessors. Reviving the lustrous beauty of 400 years ago – this is Sato's challenge.
