This is a killer hornet native to Japan. This may not look that terrifying but an attack from one of these wasps can be fatal. They are more common than people think. If any locals find a nest, the prefecture office must be contacted. Officials will come and remove it. They are too dangerous for anyone to tamper with. The wasps will go after anyone they perceive as a threat. I was told that if I came across one, just to back off slowly and not run. Just back away slowly. They are not a big problem in the city, but out in the country, they do propogate. When officials remove them, they do it at night when the hive is asleep and wearing special protective clothing.
