discontinued after the Meiji Restoration. Industry Main industries in Nii-jima include commercial and sports fishing, construction, koga rock mining, and tourism. There is also some small scale farming. Koga stone, a pumice-derived rock of rhyolite was utilized as house building material. Now its silica component is used to make transparent green glass art. It can also be used to make moyai art. The stone is indigenous only to Nii-jima and Lipari Island, Italy. Tourism Sites Maehama Beach on the western side of Nii-jima sees many wind surfers. The triathlon and ocean water swims take place here. Mount Fuji can often be seen from Maehama. Habushi Beach, on the eastern side of the island, is a nationally protected reserve with its waves and white sand, and is a good location for surfing. The beach is approximately 6.5 km long and is overlooked by koga volcanic cliffs, the highest of which is 250 meters. Moyai Hill, overlooking Yunohama and Maehama beaches, contains more than 100 large stone carvings. In the local dialect, moyai means 'to work together in effort', and these statues make evident this effort. On the western side of JR Shibuya in Tokyo proper is a giant moyai statue, a gift from the people of Nii-jima. Yunohama Onsen hot spring, on Yunohama Beach, is a large outdoor bath built in the style of pseudo-Greek ruins that provides stunning panoramic views of the setting sun and the Pacific Ocean. The bath itself accommodates up to 100 bathers. Water used in the bath is drawn from the ocean below. Jūsansha Jinja, is a Shinto shrine at the base of the cliffs of Mount Miyatsuka in the north-western corner of the main village on the island. This shrine, built in the Edo period, is recognized as caretakers of intangible cultural assets by the Tokyo government for the kagura music and sacred dancing, known as shishi-kiyari that are held every December 8. Nearby Jūsansha is Chōei-ji, Chōei Temple, a temple dedicated to Nichiren Buddhism. Beside the temple lies the Exiles' Cemetery. The cemetery, covered with the local white sand, is dominated by the gravestones of the 118 exiles, banished to Niijima by the Tokugawa Shogunate during the Edo era for non-political crimes. A short walk from Chōei Temple is the Exile Execution Ground. Eleven exiles who committed crimes on the island were executed here. Komori Yasu, from the kabuki story 'Yowa Nasake Ukinano Yokoguchi'
