Fish-Man Island is the only known underwater island of the Grand Line and it located 30,000 feet under the land mass known as the Red Line. This makes it the only island on the half way point for all who are trying to cross to the New World, the second half of the Grand Line. Due to the inedible depths, a normal ship or submarine can not reach it. A ship requires a special bubble coating to survive the dangerous journey.

This is the only location on the ocean's floor that light reaches. That is becasue of the roots of the Sun Tree Eve (陽樹イブ Yōju Ibu) reaches from the top of the Red Line and to the ocean floor. There are many theories for the reason, but the tree absorbs the light from the surface and carries it all the way to the roots. When night falls on the surface, the light also dims for Fish-Man Island. The Sun Tree Eve also releases oxygen to resupply the island.

The entire island is covered by a double layer bubble that holds in the air and water. Safe entry can only be made through the official entrance gate.
