Visit Sado, ablaze with colour for autumn pleasures.

Sansuke and Okiku, who are reputed to started rice cultivation in Sado, are enshrined at the two peaks of Mt. Ogamiyama and Mt. Megumiyama in the middle of the Kosado area. The southern slopes are known as a spot to see beautiful autumn foliage, and lead to Momijiyama Park. You can walk around the park on a promenade and enjoy views from a viewing deck in the park.

Osado Skyline is approximately 30km-long route for a scenic drive between Kanai and Aikawa. The highest point is above 900m, and you can look over the entire island, from Mano Bay, Ryotsu Bay, Kuninaka Plain to Kosado Mountains. The view from Hakuundai, a rest area with a viewing deck, is stunning. The scenery in each season such as fresh foliage in early summer and red leaves in autumn is a must-see.

Mount Donden, officially named Mt Tadaramine, is the whole highland area including three mountains above 900m. As the nickname,originated from the word "donden", which means roundtop mountain, indicates, Mount Donden is located at the heart of steep Osado Mountains and solely appears with modest inclines among the mountains. The surrounding area is a treasury of alpine plants and wildflowers. Mount Donden is one of the new Top 100 Mountains and TOP 100 Mountains of Flowers in Japan and many trekkers visit there from April towards early Summer.

Hakuundai is a lodge-style building standing at about 850 metres above sea level. The viewing terrace offers a stunning panoramic view across Sado, including Ryotsu Bay, Kuninaka Plain and Ogi Peninsula. At the souvenir shop inside the building, you will find Sado specialties, such as "Okesa persimmon butter", "fig jam", and "wild grape wine". Curry over rice with the Island's black Berkshire pork, and soft ice cream made from fresh cream are special menu items at the light meal corner. Hakuundai is closed for winter as Osado Skyline will be closed due to snow.

Tamemori Endo (Abutsubo Nittoku Shonin) served Nichiren upon being exiled to Sado and became an avid believer of the Hokke mantra. Together with his wife, Sen-nichini (a Buddhist nun), he opened his residence as a temple in 1278, and this is said to be the origin of Myosenji Temple. The temple used to be a residence of the Takeda Honma clan, deputy governor of Sado, and the ambience of a castle still remains. On site stands the only five-story pagoda in Niigata Prefecture, as well as the grave of Suketomo Hino, who was forced into exile on Sado after the Shochu Incident.

Under Emperor Kanmu's ordinance, Seisuiji Temple was founded in 808 by Ken'o Hoshi, a Buddhist monk who came from Kyoto on a missionary tour. There is Guzeden (literally: salvation) Hall, imitating the wooden stage at KiyomizuderaTemple (written in the same characters as Seisuiji: 清水寺 in Japanese) in Kyoto, but the main object of worship is 1,000-armed Kannon Bosatsu (Guanyin: Goddes of Mercy), also in imitation of Kiyomizudera Temple. Enmeizenzaijurosonten (the god of longevity) is worshipped at this temple, too, and a painting called, "Zenzaijurojin," by Mahori Hogan Yoshitaka, a master artist, was donated. Seisuiji Temple is one of the temples on Sado's Seven Gods of Fortune pilgrimage route.

Keikuji Temple is a temple of the Shingon School (founded in 807) with Dainichi Nyorai (Mahavairocana: supreme Buddha of the Cosmos) as the main object of worship. The name of the temple "Keikuji (written as 慶宮 in Japanese) derives from the lore that Emperor Juntoku's eldest daughter, Princess Keishi (慶子), spent her life here. The Princess worshipped Fukurokuju Sonten (God of Longevity), so a master artist, Mahori Hogan Yoshitaka, donated a painting entitled "Jingo (divine protection) Fukurokuju". Keikuji Temple is one of the temples on Sado's Seven Gods of Fortune pilgrimage route. Hasso (eight patriarchs) Hall, equipped with an octagonal shrine with a rotational system, is one of a Niigata Prefecture's Tangible Cultural Assets.
