Okinawa has three species of pit vipers and one coral snake. These venomous snakes are commonly found in the jungle. They are sometimes found in neighborhoods and local parks at nighttime during the summer season. Majority of the snake bites that I am familiar with happened on neighborhood night walks or harvesting sugar cane. I have seen pit vipers on public roads at night, on sidewalks, crawling on fences, on rock walls, in drainage ditches and inside vending machines.
The Okinawan Habu is the largest and most venomous pit viper found on Okinawa.

The Taiwanese Habu was introduced to Okinawa in the 1970′s. They were imported for exhibitions and medical purposes. Somehow a few escaped and have populated the Island. I have seen over a dozen on my night hikes near Ryukyu Mura in Onna village.

The Okinawan coral snake is extremely rare. I have only seen two specimens

Ways to avoid injury!
- Avoid catching or handling venomous snakes
- Wear exposure protection, such as snake boots when exploring the forest at night.
- Bring a flashlight on night walks in the neighborhood
Safety first or pay the worst!
