Nagasaki Kunchi
Kunchi, also Nagasaki Kunchi or Nagasaki Okunchi, is the most famous festival held in Nagasaki, Japan. From October 7–9 the presentations of the festival, which vividly reflect Nagasaki's colourful history, spill over from the three festival sites into the streets and create an atmosphere of celebration throughout the city.
Background
The event began as a celebration of autumn harvests in the late 16th century and became a shrine festival when Suwa Shrine was founded in 1614. The name kunchi is derived from the word. The festival originally began on the seventh day of the month and lasted through the ninth day, maintained today as Okunchi's start date of October 7 and end date of October 9.According to local explanation, another purpose was to check for hidden Christians after the ban on Christianity. This is still evident today in the custom of garden showing, when the presenting neighbourhoods open up their homes to public scrutiny.
