Reference excerpt

Itsukushima Shrine (厳島神社, Itsukushima-jinja) is a Shinto shrine on the island of Itsukushima (popularly known as Miyajima), best known for its "floating" torii. It is in the city of Hatsukaichi, in Hiroshima Prefecture in Japan, accessible from the mainland by ferry at Miyajimaguchi Station. The shrine complex is listed as a UNESCO World Heritage Site, and the Japanese government has designated several buildings and possessions as National Treasures. The Itsukushima shrine is one of Japan's most popular tourist attractions. It is most famous for its dramatic gate, or torii, on the outskirts of the shrine, the sacred peaks of Mount Misen, extensive forests, and its ocean view. The shrine complex itself consists of two main buildings: the Honsha shrine and the Sessha Marodo-jinja, as well as 17 other different buildings and structures that help to distinguish it.

History

Origin Itsukushima jinja was the chief Shinto shrine (ichinomiya) of Aki Province. This shrine is one of the "Three Great Shrines of Aki Province", along with Take Shrine and Hayatani Shrine. The first torii on the site is said to have been erected in 569, supposedly by Saeki Kuramoto during the reign of Empress Suiko (592–628 CE). Although a torii has been in place at the site since 1168, the current structure dates to 1875. The present shrine has been popularly attributed to Taira no Kiyomori, a prominent noble of the Imperial Court and later Chancellor (Daijō-daijin), who contributed heavily to the construction of the shrine during his time as governor of Aki Province in 1168. Another renowned patron of the shrine was Mōri Motonari, lord of Chōshū Domain, who was responsible for rebuilding the honden in 1571. As a result of waging war against Sue Takafusa there in 1555, Motonari is said to have tainted the island's grounds by battling on the island. Spilling blood violated the strict taboos meant to preserve the sacred purity associated with Shinto shrines. The only surviving structure in Itsukushima shrine from the Kamakura period is the Kyakuden or "Guest-God's Shrine".

Kiyomori It was not uncommon during the 12th century for the nobility to build shrines or take on other architectural projects in order to "reflect their power and splendor". The Taira clan are known specifically for their involvement in maritime trade with the Song dynasty (960–1279) and for attempting to monopolize overseas trade along the Inland Sea. Kiyomori was at the height of his power when he established the Taira dominion over the island. He "ordered construction of the main hall of Itsukushima shrine as a display of reverence for the tutelary god of navigation and to serve as a base for maritime activities". Miyajima soon became the Taira family shrine. Supposedly, Kiyomori chose the location also for the reason to further establish himself in the Heian aristocracy as one who deviated from the social norms of Shinto pilgrimage. He lavished great wealth upon Itsukushima, and he enjoyed showing the place to his friends and colleagues, or even to royal personages". It is also said that Kiyomori rebuilt the shrine on account of a dream he had of an old monk who promised him dominion over Japan if he constructed a shrine on the island of Miyajima and paid homage to its kami who are enshrined there for his success in life. The renovations funded by the Taira allowed for Itsukushima to "grow into an important religious complex".

Religious significance The Itsukushima shrine is dedicated to the three daughters of Susano-o no Mikoto: Ichikishimahime no mikoto, Tagorihime no mikoto, and Tagitsuhime no mikoto. Otherwise known as the sanjoshin or "three female deities", these Shinto deities are the goddesses of seas and storms. Kiyomori believed the goddesses to be "manifestations of Kannon", therefore the island was understood as the home of the bodhisattva. In Japanese, the word Itsukushima translates to "island dedicated to the gods". The island itself is also considered to be a god, which is why the shrine was built on the outskirts of the island. Adding to its sanctity, Mount Misen is the tallest peak at about 1,755 feet (535 m). Tourists can either hike or take a ropeway to the top. Its treasures include the celebrated Heike Nōkyō, or "Sutras dedicated by the House of Taira". These consist of thirty-two scrolls, on which the Lotus, Amida, and Heart sutras have been copied by Kiyomori, his sons, and other members of the family, each completing the transcription of one scroll, and it was "decorated with silver, gold, and mother-of-pearl by himself [Kiyomori] and other members of his clan".

Originally Itsukushima was a pure Shinto shrine "where no births or deaths were allowed to cause pollution". Because the island itself has been considered sacred, commoners were not allowed to set foot on it throughout much of its history to maintain its purity. Retaining the purity of the shrine is so important that since 1878, no deaths or births have been permitted near it. To this day, pregnant women are supposed to retreat to the mainland as the day of delivery approaches, as are the terminally ill or the very elderly whose passing has become imminent. Burials on the island are forbidden. To allow pilgrims to approach, the shrine was built like a pier over the water, so that it appeared to float, separate from the land. The red entrance gate, or torii, was built over the water for much the same reason. Commoners had to steer their boats through the torii before approaching the shrine.

Architecture

Japan has gone to great lengths to preserve the twelfth-century-style architecture of the Shrine throughout history. The shrine was designed and built according to the Shinden-zukuri style, equipped with pier-like structures over the Matsushima bay in order to create the illusion of floating on the water, separate from the island, which could be approached by the devout "like a palace on the sea". This idea of intertwining architecture and nature is reflective of a popular trend during the 16th century as well as the Heian period in which Japanese structures tended to "follow after their environment", often allowing trees, water, and other forms of natural beauty to enter into the decor of homes and buildings. That led to a far more intimate relationship between the two.

Worked examples

Example 1 — a first encounter with Itsukushima Shrine

Start with the simplest possible case. Write down what Itsukushima Shrine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Itsukushima Shrine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Itsukushima Shrine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Itsukushima Shrine

In research
Itsukushima Shrine appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Itsukushima Shrine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Itsukushima Shrine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Beppyo shrines, Buildings and structures completed in 1168, Buildings and structures in Hatsukaichi, Hiroshima, so understanding it makes those chapters shorter.
In everyday life
Look for Itsukushima Shrine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
