The Nagasaki Kunchi (長崎くんち) is the festival of Suwa Shrine that has been annually celebrated for about 400 years. A distinct feature of this festival is that it incorporates different aspects of Chinese and Dutch cultures, which have played a role in the city's history. The festival's name is believed to come from ku-nichi ("9th day"), the ninth day of the ninth month of the lunar calendar.

The highlights of Nagasaki Kunchi Festival are the dance and show performances by groups representing Nagasaki's various city districts. Each district participates only once every seven years, so this festival remains fresh to even the regular viewer.
