Festivals have many meanings. These include prayer for a bumper crop, or expression of gratitude after crop harvest.
At the festivals, you can see lots of people wearing Japanese traditional clothes called “Yukata”.
Among various types of festivals, there is a festival called “Noryousai”, which is held for people who want to escape summer heat and enjoy cool evening.
If fireworks are displayed in “Noryousai”, the festival can also be called “Hanabitaikai” or firework displays.
