Hunters have been hired to kill the boars. So far around 800 have been killed. Boar meat is a popular dish in Japan. However, the meat of these boars is too dangerous to eat. In fact, it is 300 times over the safe limit. Disposing of the dead boars is very problematic; there are very few facilities to handle them.
Now, there are many wild animals in the area. There are reports of large populations of wild dogs and rats, as well.
