The scattering of garbage by crows (karasu) is a significant social problem in Japan, and legions of neighborhood association representatives, usually grumpy older people, are out there enforcing rules designed to curb that problem. Most areas have laws requiring that garbage be protected against the scourge of crow related scattering and if you live in a standalone dwelling especially, you are responsible for ensuring that neighborhood association is not discussing your garbage and its present distribution across the neighborhood.
Fear not, preventing a knock on the door and an early morning supervised effort gathering up garbage is pretty simple. You need to buy some readily available products and use them correctly! Here are a few of the most commonly used options to foil the crows and keep your neighbors happy.
Just hang these flashers near your garbage area, and the light ingredient and a bioactive substance used in them will stimulate the eyes of the crow and prevent them from approaching. It’s like a scarecrow, only different, but besides the differences, it’s precisely the same. Understand? Great!

These flashers also “stimulate the eye of the crow,” which sort of sounds like a bad movie title. These belt-shaped strings of spiral rings give off a glaring reflected light, and crows are afraid of it. No sunglasses, because they do not have external ears on which to hang them.

Take cover! Using a crow net will keep the crows out of your trash. This type opens like an umbrella, and here comes the hard part, covers the garbage. It sounds harder than it is, I assure you. The pungent capsaicin (same chemical used in pepper spray) used in the net stimulates the taste of the crow, AKA; it tastes SPICY and crows, unlike tasteful human beings, do not appreciate it. The yellow color of the net also disturbs the view of the crow; I am not sure if they don’t like it, or it acts as a camouflage, but crows are not into the color yellow. Make a note of it!
