In Shinto, shintai ( 神体 , "body of the kami"), or go-shintai ( 御神体 , "sacred body of the kami") when the honorific prefix go- is used, are physical objects worshipped at or near Shinto shrines as repositories in which spirits or kami reside.  Shintai used in Shrine Shinto (Jinja Shinto) can be also called mitamashiro ( 御霊代 , "spirit replacement" or "substitute"). 
In spite of what their name may suggest, shintai are not themselves part of kami, but rather just temporary repositories which make them accessible to human beings for worship.  Shintai are also of necessity yorishiro , that is objects by their very nature capable of attracting kami.
The most common shintai are man-made objects like mirrors, swords, jewels (for example comma-shaped stones called magatama), gohei (wands used during religious rites), and sculptures of kami called shinzō ( 神像 ),  but they can be also natural objects such as rocks (shinishi ( 神石 )), mountains (shintai-zan ( 神体山 )), trees (shinboku ( 神木 )), and waterfalls (shintaki ( 神滝 ))  Before the forcible separation of kami and Buddhas of 1868 ( shinbutsu bunri ) a shintai could even be the statue of a Buddhist deity.
Famous shintai include the mirror (part of the Imperial Regalia of Japan), Mount Miwa, Mount Nantai, the Nachi Falls, and the Meoto Iwa rocks. Many mountains like Mount Miwa or the Three Mountains of Kumano (Kumano sanzan) are considered shintai and are therefore called shintaizan (神体山, shintai mountain).  The most widely known and renowned shintai is Mount Fuji. 
A yokozuna , a wrestler at the top of sumo's power pyramid, is a living shintai. For this reason, his waist is circled by a shimenawa , a sacred rope which protects sacred objects from evil spirits. A kannushi, that is, a Shinto priest, can become a living shintai when a kami enters his body during religious ceremonies.
The founding of a new shrine requires the presence of either a pre-existing, naturally occurring shintai (for example a rock or waterfall housing a local kami), or of an artificial one, which must therefore be procured or made to the purpose. An example of the first case are the Nachi Falls, worshiped at Hiryū Shrine near Kumano Nachi Taisha and believed to be inhabited by a kami called Hiryū Gongen.  In the second, the mitama (spirit) of a kami is divided in half through a process called kanjō and one of the halves is then stored in a yorishiro. This is the process which has led to the creation of networks of shrines housing the same kami, as for example the Hachiman shrine, Inari shrine or Kumano shrine networks.
Because over the years the shintai is wrapped in more and more layers of precious cloth and stored in more and more boxes without being ever inspected, its exact identity may become forgotten. 
The first role of a shrine is to house and protect its shintai and the kami which inhabits it.  If a shrine has more than one building, the one containing the shintai is called honden ; because it is meant for the exclusive use of the kami, it is always closed to the public and is not used for prayer or religious ceremonies. The shintai leaves the honden only during festivals (matsuri), when it is put in a "divine palanquin" ( mikoshi , a term usually translated in English as "portable shrine"  ), and carried around the streets among the faithful.  The portable shrine is used to physically protect the shintai and to hide it from sight. 
An example of the importance of a sacred tree is the 700-year-old camphor growing in the middle of Kayashima Station. Locals protested against moving the tree when the railway station had to be expanded, so the station was built around it. 
Inari Ōkami, also called Ō-Inari (大稲荷), is the Japanese kami of foxes, fertility, rice, tea and sake, of agriculture and industry, of general prosperity and worldly success, and one of the principal kami of Shinto. In earlier Japan, Inari was also the patron of swordsmiths and merchants. Represented as male, female, or androgynous, Inari is sometimes seen as a collective of three or five individual kami. Inari appears to have been worshipped since the founding of a shrine at Inari Mountain in 711 AD, although some scholars believe that worship started in the late 5th century.
A Shinto shrine is a structure whose main purpose is to house ("enshrine") one or more kami, the deities of the Shinto religion.
The Japanese term shinbutsu bunri (神仏分離) indicates the separation of Shinto from Buddhism, introduced after the Meiji Restoration which separated Shinto kami from buddhas, and also Buddhist temples from Shinto shrines, which were originally amalgamated. It is a yojijukugo phrase.
Nachi Falls in Nachikatsuura, Wakayama Prefecture, Japan, is one of the best-known waterfalls in Japan. With a drop of 133 meters, it is the country's tallest water fall with single uninterrupted drop; however, the tallest waterfalls with multiple drops in Japan are Hannoki Falls, at 497 m (seasonal), and Shōmyō Falls, at 350m.
Shimenawa are lengths of laid rice straw or hemp rope used for ritual purification in the Shinto religion.
In Shinto shrine architecture, the honden, also called shinden (神殿), or sometimes shōden (昇殿) as in Ise Shrine's case, is the most sacred building at a Shinto shrine, intended purely for the use of the enshrined kami, usually symbolized by a mirror or sometimes by a statue. The building is normally in the rear of the shrine and closed to the general public. In front of it usually stands the haiden, or oratory. The haiden is often connected to the honden by a heiden, or hall of offerings.
A Kumano shrine is a type of Shinto shrine which enshrines the three Kumano mountains: Hongū, Shingū, and Nachi [Kumano Gongen (熊野権現)]. There are more than 3,000 Kumano shrines in Japan, and each has received its kami from another Kumano shrine through a process of propagation called bunrei (分霊) or kanjō (勧請).
Himorogi in Shinto terminology are sacred spaces or altars used to worship. In their simplest form, they are square areas with green bamboo or sakaki at the corners without architecture. These in turn support sacred ropes (shimenawa) decorated with streamers called shide. A branch of sakaki or some other evergreen at the center acts as a yorishiro, a physical representation of the presence of the kami, a being which is in itself incorporeal.
Futarasan jinja (二荒山神社) is a Shinto shrine in the city of Nikkō, Tochigi Prefecture, Japan. It is also known as Nikkō Futarasan Shrine, to distinguish it from the Utsunomiya Futarayama Jinja, which shares the same kanji in its name. Both shrines also claim the title of ichinomiya of former Shimotsuke Province. The main festival of the shrine is held annually from April 13 to April 17. The shrine consists of three geographically separate sections. The main shrine is located between Nikkō Tōshō-gū and the Taiyū-in Mausoleum. Many visitors go to all three, as well as to Rinnō-ji; which are part of the Shrines and Temples of Nikkō UNESCO World Heritage Site. The "middle shrine" is located of the shore of Lake Chuzenji and the "inner shrine" is located at the summit of Mount Nantai, the volcano overlooking the lake. The shrine possesses two swords that are National treasures of Japan. Additionally, dozens of buildings and cultural artifacts are listed as National Important Cultural Properties. The precincts were also designated a National Historic Site.
Kumano Nachi Taisha (熊野那智大社) is a Shinto shrine and part of the UNESCO-designated World Heritage Sacred Sites and Pilgrimage Routes in the Kii Mountain Range of Japan. The Kumano Kodō route connects it to other sites under the same classification, which are primarily located in Wakayama Prefecture, Japan. The four sites on the route, classified as pilgrimage destinations and World Heritage Sites, are: 1) Nachi Taisha; 2) Hongū Taisha; 3) Hayatama Taisha; 4) Koya-san.
Kanjō (勧請) in Shinto terminology indicates a propagation process through which a kami, previously divided through a process called bunrei, is invited to another location and there re-enshrined.
A gongen (権現), literally "incarnation", was believed to be the manifestation of a buddha in the form of an indigenous kami, an entity who had come to guide the people to salvation, during the era of shinbutsu-shūgō in premodern Japan. The words gonge (権化) and kegen (化現) are synonyms for gongen. Gongen shinkō (権現信仰) is the term for belief in the existence of gongen.
A yorishiro (依り代/依代/憑り代/憑代) in Shinto terminology is an object capable of attracting spirits called kami, thus giving them a physical space to occupy during religious ceremonies. Yorishiro are used during ceremonies to call the kami for worship. The word itself literally means "approach substitute". Once a yorishiro actually houses a kami, it is called a shintai. Ropes called shimenawa decorated with paper streamers called shide often surround yorishiro to make their sacredness manifest. Persons can play the same role as a yorishiro, and in that case are called yorimashi or kamigakari.

Ōmiwa Shrine, also known as Miwa Shrine, is a Shinto shrine located in Sakurai, Nara Prefecture, Japan. The shrine is noted because it contains no sacred images or objects because it is believed to serve Mount Miwa, the mountain on which it stands. For the same reason, it has a worship hall, but no place for the deity to be housed. In this sense, it is a model of what the first Shinto shrines were like. Ōmiwa Shrine is one of the oldest extant Shinto shrines in Japan and the site has been sacred ground for some of the earliest religious practices in Japan. Because of this, it has sometimes been named as Japan's first shrine. Ōmiwa Shrine is a tutelary shrine of the Japanese sake brewers.
The term shinboku (神木) refers to a tree or sometimes forest as a shintai.
Iwakura (岩倉) refers to the belief in rocks as Yorishiro containing Kami in ancient Shinto. It also refers to the rock itself, which is the object of worship.
Kannabi refers to a region in shinto that is a Shintai itself, or hosts a kami. They are generally either mountains or forests.
Chinju-no-mori (鎮守の森) are forests established and maintained in or around shrines (Chinjugami) in Japan, surrounding temples, Sando, and places of worship.
