Golden Week in May is one of the most fun weeks for many Japanese people. Golden Week is celebrated from the end of April to the first week of May because imperial-related national holidays fall within these days. The weather is warm but not yet too hot, so people take days off and go on vacation! The days immediately after Golden Week are still fun for people in Tokyo because of the Sanja Matsuri festival in Sensoji Temple. Sensoji Temple is popular for tourists from overseas, so this is a good time to experience a Japanese festival at such a famous site in Japan.
