[2][3] Mount Gusuku is considered a symbol of Iejima due to its distinctive conical shape.

[1][3][4] The Japanese reading for the mountain is "Shiro-yama;" however, in Okinawan, it is pronounced "Gusuku-yama."

[2] Mount Gusuku is 70 million years older than the rest of Iejima.

Historically the utaki at Mount Gusuku has been utilized for prayers for safe sea voyages and crops.
