Japanese festivals are traditional festive occasions. Some festivals have their roots in Chinese festivals centuries ago, but have undergone great changes as they mixed with local customs.

Some are so different that they do not even remotely resemble the original festival despite sharing the same name and date. There are also various local festivals (e.g. Tobata Gion) that are mostly unknown outside a given prefecture. It is commonly said that you will always find a festival somewhere in Japan.
