Japan is an island country in the northwest Pacific Ocean with one of Asia’s most diversified ecosystems. There are five large islands and thousands of smaller coasts, all of which are harsh and mountainous. These rocky hillsides are ideal habitat for Japan’s 47 snake species, some of which are poisonous and should be avoided at all times. Apart from Spain and Brazil, the snakes in Japan are also some of the world’s venomous ones.

Snakes flourish in Japan’s humid climate and feed on a diverse range of amphibians, rodents, and small mammals. But are there any dangerous snakes in Japan that you should be aware of? Simply said, absolutely. There are various venomous and hazardous snakes in Japan that any visitor should be aware of and avoid.

Snake bites continue to be a catastrophic and life-threatening environmental concern in tropical countries. In Japan, there were 1,670 hospitalizations due to snake bites between 2007 and 2008. The Mamushi, Japan’s most lethal and venomous snake, was responsible for the majority of these incidents.

Mamushi (Japanese Grass Snake)

The Mamushi, scientifically known as Gloydius blomhoffii, is the most frequently encountered venomous snake in Japan. This nocturnal species adorns a brownish-gray color, blending perfectly with the surroundings. It enables snakes to hide in leaf heaps and ambush unsuspecting prey. Mamushi can be found in a variety of habitats such as swamps, marshes, meadows, open woodland, and rocky hillsides.

As Japan’s most venomous snake, the Mamushi snake bites between 2,000 and 3,000 humans each year. Recovery usually takes about a week and may necessitate hospitalization; severe reactions may necessitate intensive care. A Mamushi snake bite kills about ten people in Japan each year.

Habu (Okinawa Habu)

The Habu, or Protobothrops flavoviridis, is a nocturnal pit viper indigenous to the southern regions of Japan, especially Okinawa. With its distinct triangular head and stout body, the Habu’s venomous bite can induce severe symptoms, including paralysis.

A habu snake bite can cause nausea, vomiting, hypotension, and even death. Despite its strength, deaths account for about 1% of all snake bites documented.

The Tsuta-no-mamushi, or Rhabdophis tigrinus, is a unique venomous snake that stores toxins from toads it consumes. Its characteristic dorsal stripe earns it the ‘tiger’ moniker.

Unlike other snake species, tiger keelbacks employ its poison mostly for defense against predators rather than pursuing prey. The toad venom is stored in a gland at the back of the snake’s jaw and sprayed at any predators that strike. In many cases, keelbacks prefer to escape rather than fight, emphasizing the fearful attitude of this potentially poisonous snake.

So, despite the fact that this snake is venomous, relatively few deaths have been reported due to its proclivity for defensive behavior rather than hostility and striking. This snake is easy to overlook in the wild and undergrowth since it develops to a maximum total length of 44 cm. Colors range from pale olive green to reddish-brown, with little blackish dots on some.

Yamakagashi (Himehabu)

The Yamakagashi, or Rhabdophis tigrinus, is considered less aggressive and generally avoids humans. However, when threatened, it delivers a potent venomous bite causing immediate discomfort.
