What are the traditional customs of Japanese summer festivals?

Japanese Summer Festival is the general name of various folk activities held in Japan in summer, usually held in July and August when Japan welcomes hot summer, including Gion Matsuri in Kyoto, Tenjin Matsuri in Osaka and Kanda Festival in Tokyo. During the event, most Japanese will wear kimonos to promote traditional culture and food. One of the most important traditional customs is to offer sacrifices to God, praying for good harvest, good health and long life. On this festival, people will make sacrifices to the gods in temples and shrines and pray for their protection. In addition, there are many water-related customs in summer festivals, such as swimming, dragon dancing and lion dancing. These activities are aimed at commemorating the arrival of summer and praying for a bumper harvest of water.
