But don't worry about the bees; worry about yourself. Matayak stings feel like "hot nails," and can easily pierce clothing. They're also incredibly lethal, injecting a fucked-up venom that kills red blood cells and shuts down your liver. And anyone allergic has better odds of surviving a grizzly attack than a swarm of Matayaks, because their stings cause such a bad anaphylactic shock that vulnerable people can up and die of a heart attack on the spot.
And in case you've decided to simply give Japan a miss now, even that won't save you. Matayaks have recently started forming terrible migrating swarms, because ecological changes have thinned out their natural enemies, which they apparently had. (Does "all that is good in this world" count as a natural enemy?)
In 2013, a swarm of giant hornets killed at least 42 people in one Chinese province, plunging the area into a state of emergency. And thanks to international trade, the little monsters are spreading to other continents as well. In 2018, the hornets popped up in the UK, which released an emergency message warning of an all-out invasion. Here's hoping they can find a little Bee Churchill to fight it.
