Commi Island

is the island where Nami grew up. It was simple and peaceful until the Arlong Pirates took over, setting many strict and harsh rules. For example, in order to live, adults had to pay 100,000 beli and children 50,000 beli each month. From there, Arlong and his crew built up their forces in order to take over all of East Blue, bribing corrupt Marine officials like Nezumi so that no attention was paid to them. However, the island was freed when Monkey D. Luffy defeated Arlong and toppled Arlong Park. This is the location of the Arlong arc.

This island is notable for its plantations of rice and orange.
