How do the Japanese deal with their giant hornets?

Question:

I was reading this:
http://www.cracked.com/article_15816_the…

And they seem very scary. Killing 40 people every year in a horrifying way. I wonder how the Japanese deal with this sort of problem since even inside Tokyo there are these hornets. Do they have suits and exterminators?

Answer:

I've never heard any problem caused by hornets in Japan.

How can you be sure that there are hornets killing people in Japan? Maybe the article says so? I did not read it much.

I live in Japan but don't know this. Medias never talk about it.
