Best Snorkeling in Japan

Snorkeling in Japan is best when the sea is calm and clear: low wave height, light winds and water inside a comfortable temperature range. Conditions vary a lot by spot, season and time of day, so we forecast each location below individually. As a rule of thumb, snorkel in the morning before the wind builds, and aim for the window around high tide when currents are slack and visibility is highest. Pick a spot to see its hourly snorkel score, the next good window and the best months to visit.
