北西ハワイ諸島
The Northwestern Hawaiian Islands (also known as the Leeward Islands) are the small islands and atolls in the Hawaiian island chain located northwest of the larger islands of Kauaʻi and Niʻihau. For administrative purposes, all of these islands are controlled by Honolulu County. The Northwestern Hawaiian Islands consist of nine main islands and innumerable islets, coral reefs, atolls, sandbar, and intermittent islands—some of which are officially named. All of these islands account for only 3.1075 mi² (8.0485 km²) and have no permanent residents.
