North of Kadena Air Base in the East China Sea, the snorkeling at Maeda is considered the best shore-accessed dive site in Okinawa. There are actually two separate snorkeling dive sites known as Maeda Point and Maeda Flats, both of which are very popular for the visibility. You can expect to see healthy corals and diverse marine life. Occasionally, the Maeda Point snorkeling can be a crowded affair.
From the Maeda Point parking area, there is a short, but steep, stairway down to the rocky entry point for the snorkeling dive.
The snorkeling on Okinawa is best from May through October when the water temperature is more enjoyable for snorkelers. However, that is also the prime time for the stinging Habo Jellyfish, which is a type of box jellyfish. Since 2012, the local authorities have been posting more snorkeling restrictions/prohibitions at Okinawa beaches, so make sure to look for signs and follow them to avoid being arrested.
To reach the snorkeling in Okinawa by air, you will need to fly into Okinawa Naha Airport (OKA) on southern end of island. From the airport, there is a public bus #120 and also an airport limo bus that both head towards Maeda.
Overall, Maeda Point is the 3rd most popular snorkel dive spot of all 12 snorkeling dives in Japan.
