History and Predominant Feature of the Nihojima

History of the island of Nihojima near Hiroshima city

During the Jomon and Yayoi periods, the water level of Hiroshima Bay was high, and the Otagawa Delta did not exist. Only small islands such as "Niho-jima," "Ni no Shima," "Kanawa-jima," and "Unajima" were present. People began to inhabit Niho-jima from Yamato period (390 AD), and it played a significant role as one of Japan's leading cinnabar mining sites known as "Niu.".
In the west, there is the "Miyajima of Aki," and in the east, there is "Niho-jima(Niho Island)," both of which were said to delight passing ships. A poem from the early Heian period by the court noble and poet Ono no Takamura (also known as Sangi Takamura) (802-851 AD) remains: "Entering the sea, crossing twenty bays, among the ten islands, the island with a deep fragrance is one of the seven bays." The term "seven bays" refers to fishing bases, including "Housogi Bay," "Fuchizaki Bay," "Hiuna Bay," "Tanna Bay," "Oko Bay," "Honura Bay," and the "Mukainada Bay" of Mukainada-jima.

Due to Niho-jima's primary industry being fishing, the populace owned one or more boats per household, enabling them to engage in naval warfare as mariners. Consequently, there were battles among various local clans vying for control of the island's naval forces. Later, under the rule of the Aki Takeda clan, the guardians of Aki Province, the islanders served as guides and were referred to as pirates (security forces). In the early Edo period, "Ninoshima," "Kanawajima," "Touge-jima," "Kakuma-jima (Benten-jima)," "Kobenten-jima," "Ando-jima," and "Ujina-jima" were incorporated, forming the "Ninoshima Village" in Anan District. It became known as the "largest village in Japan."
In the year 1662 (Kanbun 2), an embankment was constructed from Hijiyama(Mt. Hiji) to Ohkou Bay on Niho-jima. Subsequently, in the following year, 1663 (Kanbun 3), the areas known as "Nino-jima west shinkai" and "Nino-jima east shinkai" were developed, linking Nino-jima seamlessly with the Hiroshima Castle area, including Hijiyama. In 1664, the address of Nino-jima Village was changed from "Annan District" to "Aki District."

After becoming connected, the lifestyle of local population transformed into a blend of fishing and upland farming known as "half-farming, half-fishing." Additionally, due to limited fishing grounds, residents sought new opportunities in areas such as Hokkaido, Hawaii, California, and Brazil between approximately 1885 and 1924. A significant number of people migrated, with 96% of immigrants originating from Hiroshima Prefecture (38.2%), Yamaguchi Prefecture, Kumamoto Prefecture, and Fukuoka Prefecture. Notably, among the Hawaiian immigrants, 997 were residents of Nino-jima Village. On August 31, 1917 (Taisho 6th year), "Nino-jima Village" in Aki District was renamed to "Nino Village." Then, on April 1, 1929(Showa 4th year), "Niho Village" was incorporated into "Hiroshima City" and became known as "Hiroshima City Nino."

Well‐Known Products of Nihojima
