Futarasan Jinja shrine, standing next to Toshogu, is dedicated to the deities of the sacred mountains of Nikko: Mount Nantai, Mount Nyoho, and Mount Taro. The sacred bridge Shinkyo Bridge is also part of the Futarasan shrine.
It was founded by Shodo Shonin, a Buddhist monk who introduced Buddhism in Nikko and also founded Rinnoji, in 782. It is now a part of the holy trinity (Toshogu Shrine, Futarasan Shrine, and Rinnoji Temple) designated as UNESCO World Heritage Site as Shrines and Temples of Nikko.
There is a small forested garden within the shrine complex, which stands more shrine buildings and a spring, surrounded by old sacred trees, which is not covered by free admission.
There are two more Futarasan Shrines: One is in the Summit of Mount Nantai and the other is at Lake Chuzenji.
Futarasan can be accessed from JR or Tobu Nikko Station, and a bus that unloads at Shinkyo bus stop. Alternatively, it is 29-30 minutes on foot from the station. It is located on the west of Tosho-gu.
Rinno-ji, Tosho-gu, Futarasan, and Taiyu-in is situated in the same site, north of the Shin-kyo bridge. The temples and shrines be accessed in a combined ticket worth 1000 yen, except for the Treasure Museums of Rinno-ji and Tosho-gu, and the path leading to the tomb of Ieyasu with the sculpture of the Sleeping Cat (520 yen). However, the combined ticket was suspended due to lack of consensus between the shrines and temples.
Futarasan is open 8:00 to 17:00 (April-October) and 8:00-16:00 (November-March). Entrance costs 200 yen, when not included in the combined ticket with the temples near the Shin-kyo Bridge, and 200 yen for entry to the garden.
