Japanese word ‘Habu’ refers to a particular type of snake that inhabits the Ryukyu Islands. These snakes are also known as Tree Vipers or Pit Vipers. There are three species of Habus found on Okinawa. Two of these species have been introduced and one is native to the island. They are all venomous snakes that feed mainly on rodents and other small mammals.

Okinawan Pit Vipers are large, venomous and can be aggressive when provoked, but on the island of Okinawa these dangerous creatures are not always regarded as being something to avoid. It is the custom in Okinawa to catch these snakes and use their bodies to make a potent drink known as Habu sake.

Native Okinawa Pit Vipers are of a pale greenish yellow color and are marked with a wavy pattern of dark green patches with yellow edges. The underside is much plainer and almost white.

A Okinawan Pit Viper can grow up to eight feet long, although most of them don’t reach that size. The introduced species are only three or four feet in length and are more gray-brown in appearance than the native Okinawa Habu.

On Okinawa Island it is important to know what to do in case you get bitten by one of these aggressive snakes. These Pit Vipers' venom is not always lethal but it is hemotoxic, which means it can do a lot of harm to blood cells while poisoning the blood.

Victims of a Okinawan Pit Viper bite may die or can suffer permanent disability if they do not get immediate medical attention. The thing you should never do is to apply a tight binding around the bite. This will only allow the venom to have a worse affect in that area.

The correct action to take when this snake bites someone is to clean up the area around the bite in order to prevent infection within the bloodstream. The affected part of the body will need to be kept immobile until a medical professional can treat the victim.

Statistics show that the population of Okinawa is known to have some of the longest-living inhabitants in the world. The presence of Okinawan Pit Vipers is obviously not a huge threat to all Okinawans, and the availability of effective medical treatment means that a bite does not have to be debilitating or result in death.

Okinawan Pit Vipers are more active in the summer months and can often be seen basking on rocky ledges. They can also be found in caves. Most of the snakes inhabit forested areas, but they will move out into farmland and cross fields that are close to fresh water. Okinawan Pit Vipers also appear in and around human settlements, where they are known to hide in old tombs and inside traditional walls made of limestone rocks.

Some Okinawans who know where Okinawan Pit Vipers are found collect large numbers of them and use their bodies to make Habu sake. This strong liquor is often drunk from bottles containing the remains of the snake itself. It is also believed to have medicinal qualities.

The toxicity of Okinawan Pit Viper venom is neutralized by alcohol during the process of preparing it. A jar or a bottle of the sake may contain a complete snake that has been submerged in alcohol and may have a strong smell, but the drink has a less obnoxious smell when the snake’s guts are removed before it is submerged.

If it is true that Okinawan Pit Viper has a positive affect on health, then it is also possible that its consumption has contributed to the longevity of the Okinawan population. The potent drink is also supposed to increase virility, having a similar effect to taking Viagra, a belief probably having its roots in the fact that habus take for hours when they mate.

Okinawan Pit Vipers are valued as much as they are feared. They should be avoided in the wild and need to be deterred from human habitation, but with immediate medical treatment, a bite from a Okinawan Pit Viper will not kill or do any permanent damage.
