Kasedori is a traditional event in Japan where people dress up like big, scary birds and run around scaring people. On a specific day every year, people in a small town in Japan dress up in costumes made of straw and feathers to look like these big birds.
The idea behind this event is to scare away bad luck and evil spirits, so people will be safe and happy for the rest of the year. The costumes are very detailed and can look really scary, with big beaks and claws and frightening expressions.
On the day of the event, people dressed like these birds run around the streets of the town, making a lot of noise by flapping their wings and screeching. They may even chase after people, but don't worry, it's all in good fun!
Everyone in the town comes out to see the kasedori and sometimes they even have special performances where they dance and sing in their bird costumes. It's a fun and unique way to celebrate and get rid of bad luck.
