Deer devouring your arborvitae? Chowing down on your corn? You have plenty of company. In Japan. A population of 105,000 deer on the main Japanese island of Honshu - where Tokyo lies - is doing so much damage to forestry and agriculture in Nagano Prefecture that some people are calling for a truly drastic measure.

Reintroduce wolves from abroad. That's right, wolves, which vanished from Japan at the beginning of the 20th Century due to overhunting of the wolves themselves and of the deer on which they fed.

Wolf reintroduction is a second option for controlling deer. The first choice is legal sport hunting. Problem is, almost no one hunts in Japan anymore. The land where Samurai prided themselves on their ability to down game with bow and arrow and Ainu tribesmen engaged bears with spears has only a quarter as many hunters as in the past. And the number is shrinking fast.
