The mamushi is a pit viper, a type of snake that has heat-sensing pits between its eyes and nostrils. It lives in Japan, in places such as swamps, meadows and farmland. It matters because its bite is one of the most dangerous of Japan's snakes.1

It lives in swamps, marshes, meadows, open woodland, rocky hillsides and montane rock outcroppings. It is often found in and around farmland because rodents are common there.1

Its venom is mostly haemolytic, meaning it breaks down red blood cells. It also contains two neurotoxins, which attack the nerves, and an anticoagulant, which stops blood from clotting. Reported effects include kidney failure, visual disturbances and palsy (paralysis).1

About 2000 to 3000 people in Japan are bitten by a mamushi each year. Approximately 10 die annually. Severe bites require intensive care, and typical bite victims need about one week of hospital treatment.1

  • Treatment is given in hospital. It involves cutting the wound to remove venom and injecting mamushi antivenom. Pregnant women who are bitten have had miscarriages, so medical care is essential.1

Òtítọ́

1

Recovery takes a long time. Bite victims may need several months to fully recover, even after hospital treatment and weeks of follow-up care.1

2

It is highly resistant to its own venom because its blood contains neutralising factors, including phospholipase A2 (PLA2) inhibitors.1

3

Its beta-toxin acts before the nerve junction, so anticholinesterase drugs cannot block or treat its effects.1

4

Its venom contains a peptide called ablomin, which is very similar in amino acid sequence to helothermine, a venom peptide of the Mexican beaded lizard.1

5

It is considered one of the most venomous snakes in Japan, along with the yamakagashi and the Okinawan habu.1

6

Its venom varies very little across Japan in either potency or effects.1
