, also known as from its location, is a Japanese castle located in à Âmura, Nagasaki Prefecture, Japan.
Kushima castle is built on a peninsula extending into à Âmura Bay. Kushima Castle was the ancestral home of the à Âmura clan, having first been constructed in the Kamakura period by descendants of Fujiwara no Sumitomo. It was the base of Kirishitan daimyà  à Âmura Yoshiaki (1568âÂÂ1615), who assisted Toyotomi Hideyoshi in securing control of Kyà «shà «. After Hideyoshi's death and the Battle of Sekigahara, the à Âmura clan was confirmed by shà Âgun Tokugawa Ieyasu as a tozama han with revenues of 27,000 koku in their ancestral territories. The Sengoku period castle of 1598 was rebuilt in 1614 by à Âmura Sumiyori per plans draw up by noted castle designer Katà  Kiyomasa. After the start of the national isolation policy and the persecution of the Japanese Christians, many local Christians were herded into the grounds of à Âmura Castle and forced to take poison in 1616. à Âmura Sumiyori himself was poisoned in 1619.
The à Âmura daimyà  remained in residence at Kushima Castle until the Meiji Restoration of 1868. It was the seat of the local government until 1871, when the former à Âmura Domain was merged into the new Nagasaki Prefecture. The donjon was pulled down in 1871, as were all of the supporting structures. Today, only the moat and portions of stone walls remain.
In 1884, a Shinto shrine was erected on the foundations of the former keep, in honor of the spirits of the generations of à Âmura daimyà Â. In 1981, one of the yagura and some earthen walls were reconstructed. The site of the castle now forms à Âmura Park, which contains a number of protected plant species, including many examples of the à Âmura sakura and extensive public gardens.
