Wakae Island at low tide

Wakae Island, or Wakaejima(和賀江島,Wakae-jima) is an artificial island, the oldest in Japan, now in ruins. The name means "Waka Bay Island" from Waka, Zaimokuza's old name (see the text of the commemorative stele, below). Its remains are located at the east end of Zaimokuza Beach near Kamakura and are still visible at low tide. It was built in 1232 and, in spite of its state of disrepair, it has been declared a national Historic Site because it is the sole surviving example of an artificial harbor from the Kamakura period.

Japan Constitutional monarchy in East Asia

Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south.

Zaimokuza town located in Kamakura City, Kanagawa Prefecture, Japan

Zaimokuza (材木座) is an area within the Kamakura, Kanagawa Pref., in Japan that runs along the sea from Cape Iijima near Kotsubo harbor to the estuary of the Namerigawa. The relation between the beach's name and that of its neighboring areas is complex. Although Yuigahama is in fact the entire 3.2 km beach that goes from Inamuragasaki to Zaimokuza's Iijima cape, the name is usually used to indicate just its half west of the Namerigawa river, while the eastern half is called Zaimokuza Beach (材木座海岸). This is the reason why, although the beach gives its name to only the west part of the beachside area, traces of the name Yuigahama can be found also in Zaimokuza.

Kamakura period period of Japanese history

The Kamakura period is a period of Japanese history that marks the governance by the Kamakura shogunate, officially established in 1192 in Kamakura by the first shōgun, Minamoto no Yoritomo. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan.

Although its component stones have sunk in the sand, its general contour is still clearly visible when the tide is low as a mound about 200m long. On its northern side there used to be several stone pillars used to moor ships in port call to avoid strong southern winds, but they are now all lost.

Tide The periodic change of sea levels caused by the gravitational and inertial effects of the Moon, the Sun and the rotation of the Earth

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.

On the beach, a large rock surmounted by a black stele marks the position of the former port. The stele, erected by the Kamakuramachi Seinendan (Kamakura Youth Club) in 1924, explains in Japanese the history of the site and its importance.

History

During the Kamakura shogunate, Sagami Bay was busy with trading ships, but the shallowness of the bay made the use of barges indispensable. Accidents between ships were common and it was therefore decided to build a port. A priest named Ōamidabutsu(往阿弥陀仏) applied for permission from the Shogunate to build an artificial port in the area. Permission was granted in 1232.

Kamakura shogunate feudal military government of Japan

The Kamakura shogunate was a Japanese feudal military government of imperial-aristocratic rule that ruled from 1185 to 1333. The heads of the government were the shōguns. The first three were members of the Minamoto clan. The next two were members of the Fujiwara clan. The last six were minor Imperial princes.

Sagami Bay bay in Japan

Sagami Bay lies south of Kanagawa Prefecture in Honshu, central Japan, contained within the scope of the Miura Peninsula, in Kanagawa, to the east, the Izu Peninsula, in Shizuoka Prefecture, to the west, and the Shōnan coastline to the north, while the island of Izu Ōshima marks the southern extent of the bay. It lies approximately 40 kilometres (25 mi) southwest of the capital, Tokyo. Cities on the bay include Odawara, Chigasaki, Fujisawa, Hiratsuka, Itō, and Kamakura.

In its first form, the harbor functioned as both a breakwater and a wharf and was built with large stones laid as a foundation, with smaller stones on top. It was later extended gradually and repaired several times until the end of the Edo period, when it was abandoned.

Edo period period of Japanese history

The Edo period or Tokugawa period (徳川時代) is the period between 1603 and 1868 in the history of Japan, when Japanese society was under the rule of the Tokugawa shogunate and the country's 300 regional daimyō. The period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, "no more wars", and popular enjoyment of arts and culture. The shogunate was officially established in Edo on March 24, 1603, by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration on May 3, 1868, after the fall of Edo.

Text on the stele

The original inscription is in old-fashioned Japanese. Here follows a translation of the text based on the transcription in modern Japanese provided by the Kamakura Citizen Net .

"Waka" is the former name of today's Zaimokuza. This place used to be a harbor where timber was collected and shipped and, for this reason, the town's name changed soon to the present one.
Wakae Island was an embankment built to avoid the destruction by the waves of Waka's harbor. 768 years ago, a priest named Oamidabutsu asked permission for its building and, with the support of Moritsuna, work was started on July 15th and ended on August 9th.
