Okinawa Safety Guide 2025

Monitor Japan Meteorological Agency (jma.go.jp) typhoon forecasts regularly during July-October typhoon season.

Stock 2-3 days of food and water if a typhoon warning is issued; remain inside until the all-clear is given.

Swim only at supervised beaches and obey the beach flag warning system: green (safe), yellow (caution), red (closed).

Wear a jellyfish guard suit or full-coverage swimsuit May-October to protect against habu-kurage (box jellyfish).

Never swim or snorkel alone — strong ocean currents can develop suddenly, particularly on the east (Pacific) coast.

Wear reef shoes and avoid standing on coral; sharp coral cuts in tropical water are prone to serious infection.

Use reef-safe sunscreen (without oxybenzone or octinoxate) to protect Okinawa's precious coral reef ecosystems.

In rural and forested areas, wear enclosed shoes and long trousers to avoid habu snake encounters — they are venomous pit vipers that are nocturnal and often hide under rocks and wood.

Leave valuables (passports, extra cash) in your hotel safe rather than in parked rental cars, particularly at beach car parks.

Obtain travel insurance that covers typhoon-related trip cancellations and medical evacuation before traveling to Okinawa.

Carry emergency contact cards: Police 110, Ambulance/Fire 119, Coast Guard 118, English helpline 0120-46-1997.

If caught in a rip current, swim parallel to the shore to escape the current — never swim directly against it.

Be cautious at cliff viewpoints (Cape Manzamo, Cape Hedo) — barriers are not always present and paths can be slippery after rain.

Apply high-SPF sunscreen and reapply every 2 hours; the subtropical UV index in Okinawa is intense year-round, even on overcast days.

Seek prompt medical attention for any jellyfish sting: rinse with seawater (not fresh water), apply vinegar, and do not rub — seek emergency treatment for box jellyfish stings.
