The Airuzu archipelago (sometimes known as well as the Hieyoks Archipelago, but this second term it's often discussed, as could be used as well for other Hieyoker archipelagos) is the group of islands that forms the country of Hamu, and extends roughly from northeast to southwest along the northeastern coast of the Hieyoks mainland.
The archipielago is compressed by the major island, Hondo, in a central possition, Minami to the southwest and Kita to the northwest and Hoppo to the north. The archipielago consists in about 7.000 isles and islets, some inhabited and others unhabited.
