It’s a pity that this beautiful Japanese pit viper (mamushi) had been run over. It was on the path next to the road and it looked like a bicycle tyre had clipped its head. Luckily the snake was in a reasonable enough condition to be able to take some photos.
These are venomous snakes but you would have to be extremely unlucky to get bitten, since they are reclusive and slow-moving. They look worse than they are in reality and, according to the article on Wikipedia (here) of the around 3,000 people bitten each year, only ten die. Apparently, although the venom is quite strong, it’s very difficult for the snake to bite a human in a way that it can inject a large dose. I guess the only people who die are those people who try to pick them up to take photos (like me perhaps!!).
