Ogasawara Sea Turtle Season
小笠原ウミガメシーズン
Tokyo · Kanto
Sea turtle nesting on Ogasawara is a season, not a dated event, so no single day can be promised. Green turtles come ashore to nest from roughly mid-April through August with the peak in June and July, and hatchlings emerge from late July into October. Sightings depend on tide, moon and weather on the night, and observation is through licensed local tours — book one on arrival rather than planning the trip around a specific date.
