Dangerous Animals

Kumejima has a few species of animals that are dangerous to humans. If you think you have come in contact with a poisonous animal please dial 119, the Japanese emergency number to get assistance.

  • Kumejima Habu – The Kumejima Habu (Protobothrops flavoviridis)
    is a type of pit viper common throughout the Okinawan Islands. It’s often a yellowish color and is found most often in warmer weather, especially at dusk and dawn and throughout the evening hours. It is most often seen in rural areas though it can be found in streets and near the ocean as well. Avoid contact and seek emergency medical help if you are bitten. Please be aware that other types of snakes on Kumejima are not poisonous, and the Kikuzato’s Book Snake is a protected species that lives in the mountain rivers.

Earthquakes are a part of life in Japan. In the five years I’ve lived in Okinawa Prefecture, I have felt 3 small tremors. Though the ones I have felt were very small and there are fewer than other places in Japan, there is still a possibility of large earthquake. Please be prepared at all times and consider reading the US Embassy’s information on disaster preparedness.

Information on current earthquakes can be found on the Japanese Meteorological website in English.


The March 2011 Tsunami raised awareness of the danger of high waves throughout the world. Kumejima has an evacuation system with points around the Island in the event of a major tsunami. There are also occasional practice drills and signs around the island showing your current elevation above sea level. Please check the Japanese Meteorological Agency’s Website for the latest information and suggestions. On Kumejima you will hear an alarm and the words “kunren kunren” before/during a drill.

If you hear or see a warning, follow others away from water and towards the highest places you can get to. If you are on the beach, and the tide suddenly goes out, move away from it as quickly as possible as the water may receed drastically before a major tsunami.


Typhoon or hurricanes are common in the Okinawa Islands from July through November, with one or two major storms over Kumejima each year. These Hurricanes can have strong winds that cause electricity to go out and other hardships. With today’s technology, there is usually several days of warning as storms are tracked, though they can happen suddenly as well. Most buildings on Kumejima are constructed with typhoons in mind. You will find concrete and typhoon glass in many buildings. Avoid going outside during storms and avoid the ocean. Prepare for disasters as suggested on your local embassy’s website.

Most Typhoons are over within a day, though the damage from fallen trees, etc. may require more time to recover from. Stay away from windows as strong winds might brake them, or cause objects to fall into them. Prepare fresh water for drinking incase the water supply is temporarily shut off. You should also consider preparing candles and or flashlights with extra batteries.

As with all of the above, if you are staying in a hotel, familiarize yourself with the emergency plans they have on file. If you are unsure of what to do in an emergency, please ask someone.
