Beware the Habu
Habu ( Trimeresurus flavoviridis ) are poisonous pit vipers found on Okinawa. As with most snakes they keep to themselves so you’re very unlikely to see a habu in the wild while on Okinawa. Unfortunately you are likely to see one sitting at the bottom of a bottle of Awamori (Okinawan Sake). Similar to the worm in a bottle of tequila the snake is thought to give the alcohol an extra kick. Another interesting fact about the habu is that in 1910 someone made the decision to import Indian Mongooses into Okianawa to control the habu population. The mongoose has now become a serious pest on Okinawa, killing and eating virtually every native creature on Okinawa, except for… the habu.
