What to be careful of in Okinawa: wildlife hazards
Habu snake: A venomous pit viper found on land in Okinawa’s brush and forests. Rare in Naha city or resorts. You’re unlikely to encounter one on a tour, hotel walk, or beach. If you do see one, leave it alone and it will leave you alone.
Box jellyfish: Summer (mid-June to mid-September), especially July–August. Beaches install protective nets; guided snorkel tours in Kerama or Blue Cave avoid them. Stings are rare if you wear the provided wetsuit and listen to guide briefings.
Sea snakes: Present year-round, especially in warm water. Venomous but docile. Wear a wetsuit; they rarely bite unless provoked. Guides brief you to stay a distance and never touch.
Cone snails: Beautiful shells on the sea floor. Never pick up. They can deliver a venomous harpoon sting. Look, don’t touch.
Stonefish, lionfish, sea urchins: Reef residents. Wear water shoes and wetsuits. Don’t step on the reef; don’t touch anything. Guides emphasise this.
The single best defense is "look but don’t touch." Wear the provided wetsuit on every snorkel. Guides on the Kerama and Blue Cave tours manage these risks expertly.
