The Kunisaki Peninsula (国東半島, Kunisaki Hantō) is a peninsula in northern Ōita Prefecture, Kyushu, Japan that juts out into the Seto Inland Sea.[1] The peninsula is almost circular. There is Mount Futago (両子山, Futago-san) in the central part of the peninsula.[2]
See main article: article and Rokugō Manzan. On the Kunisaki Peninsula, there are several mountain valleys which radiate from the centrally-located Mount Futago outwards toward the surrounding sea. Beginning 1,300 years ago, these areas were divided into six sections. Many temples were constructed in this area and the area developed a unique religious culture. The temples and the unique culture of these valleys is referred to as Rokugō Manzan (六郷満山). This culture is said to be the birthplace of Shinbutsu-shūgō (神仏習合), or the syncretism of Shinto and Buddhism.[3] [4] thumb|Torii, typically seen at Shinto shrines, at Futago-ji Temple. This is indicative of Rokugō Manzan's mix of Shinto and Buddhist elements.
Some of the influences of Shinbutsu-shūgō can be seen in the many Rokugō Manzan Tendai sect temples. The Rokugō Manzan temples' Shinto elements originated from the influences of nearby Usa Jingū, the head shrine of Hachiman shrines in Japan. Usa Jingū, which is located in Usa at the base of the Kunisaki Peninsula, was itself influenced by Buddhist elements. In fact, the former Usa Hachimangu-ji (宇佐八幡宮寺) which was at the site of the present-day Usa Jingū is said to be the earliest example of Jingū-ji, or "mixed shrine-temple complex."[5] [6]
The most central of the Rokugō Manzan temples is Futago-ji (両子寺）which is more than 1,300 years old and is located on Mount Futago. Other important Buddhist temples and sites in the area include:
The Kunisaki Peninsula is known for its mountain climbs and hiking trails. The Kunisaki Hantou Minemichi Long Trail (国東半島峯道ロングトレイル), or simply "The Kunisaki Long Trail," is a well-known 134 kilometer-long hiking route which is located on the peninsula.[8] Hikers may choose to do the trail in its entirety or sections of it. The trail, which has been used by monks for hundreds of years, leads hikers to many of the peninsula's most notable landmarks (primarily its temples).[9] thumb|Stone Buddhist Nio guardian statue in front of a torii along the Kunisaki Long Trail. This too shows the peninsula's history of Shinbutsu-shūgō.During the trek, many stone Buddhist statues can be seen. It is said that more than half of all stone statues in Japan are located on the Kunisaki Peninsula. The trail also includes a climb of the 721 meter-tall Mount Futago, the tallest mountain on the peninsula.
