Nakamoto beach

If snorkeling is your prime objective then the expansive area of coral-rich ocean which extends from the shore is unlikely to disapoint. Some people chose to snorkel in the outer-reef area due to the diversity of life which can be encountered, but do bear in mind that venturing into deeper water further from the shore naturally carries its risks. Plus, there are no lifeguards, and the coastguard is based a fair distance away on Ishigaki.
The tide has taken its toll on the coastline and the result is some interesting rock formations at the rear of the beach which offer welcome shade from the sun.

There is also a sheltered picnic area at the top of the stairs which lead to the beach along with a small snack bar which is open throughout the warmer months. A snorkel and fin set can be rented here for 1500 yen. Lifejackets and parasols are also available.
This is one of those beaches where the local authorities seem to be being intentionally vague about whether swimming is permitted or not. On arrival you'll be greeted by a sign which reads 'swimming is dangerous' in Japanese, which differs to signs found on most beaches without safety nets which typically read 'swimming prohibited'.
The fact that a business which rents out snorkeling gear is allowed to freely operate suggests that swimming at this beach, which attracts thousands of tourists to the island every year, has at least been accepted. However, it would be nice if the local authorities would take one further step, accept some responsibility, and actually employ a couple of lifeguards.
