About Fukuoka, Japan

Fukuoka, Japan

Fukuoka, Japan is a submarine cable landing point in Japan (coordinates 33.5904°, 130.4017°). It serves 3 submarine cable systems, making it a multi-cable landing site in Japan's international connectivity infrastructure.

Fukuoka is a designated city in the Kyushu region of Japan and the capital city of Fukuoka Prefecture. The city is built along the shores of Hakata Bay, and has been a center of international commerce since ancient times. The area has long been considered the gateway to the country, as it is the nearest point among Japan's main islands to the Asian mainland. Although humans have occupied the area since the Jomon period, some of the earliest settlers of the Yayoi period arrived in the Fukuoka area. The city rose to prominence during the Yamato period, and because of the cross-cultural exposure, and relatively great distance from the social and political centers of Kyoto, Osaka, and later, Edo (Tokyo), Fukuoka gained a distinctive local culture and dialect that has persisted to the present day.
