Kaisatsuko

Kaisatsuko is a big word that means "checkpoint" in Japanese. Have you ever gone on a trip with your family and seen a police officer or a security guard standing by the road, checking cars that are passing by? That's what kaisatsuko is all about.

When you're driving on a road in Japan, you might come across a kaisatsuko. It's like a little station where police officers or security guards check your car to make sure everything is safe and secure. They might ask you to show your driver's license, registration documents, or your car insurance papers. They might also check your car to make sure you don't have anything dangerous or illegal inside.

The kaisatsuko is there to keep everyone safe and make sure that everyone is following the rules on the road. They also help catch people who might be driving drunk or breaking other rules. It might seem a little scary to see a checkpoint like this, but don't worry - the officers and guards are there to help keep you safe as you travel on the road.
