Futarasan Shrine forms part of the Shrines and Temples of Nikko, a UNESCO World Heritage Site, together with Nikko Toshogu and Rinno-ji. The listed property covers 50.8 hectares, and UNESCO describes it as a place where a long tradition of worship, high artistic achievement, and a striking harmony between architecture and the surrounding forest come together. Its buildings are a fine illustration of Edo-period architecture applied to Shinto shrines and Buddhist temples. The shrine itself holds treasures worth knowing about. Eleven buildings in the complex, including the Honden and the Haiden, are designated national Important Cultural Properties, and the shrine possesses two swords that are National Treasures of Japan. One small curiosity concerns the name. The same characters, 二荒山, also belong to a shrine in Utsunomiya, and both claim the title of ichinomiya of the former Shimotsuke Province. That is why this one is often called Nikko Futarasan Shrine. Compared with Toshogu next door, it tends to feel calmer, and visitors often linger among its cedar groves.
