East Corner is a boat-access reef corner off Nyaung Oo Phee Island in Myanmar's Mergui Archipelago, reached as part of a resort-linked or liveaboard dive plan rather than a simple shore hop. The site sits on a current-prone edge of the island, so divers should expect moving water, a guided entry, and a plan that follows tide and pickup timing. It is best approached as a macro-friendly reef stop with clear-water windows, seasonal island access, and more emphasis on control and positioning than on long swim distance.
