Official website
Nagasaki Prefecture has many islands and a long, intricate coastline. Even during the period of national isolation (sakoku), it remained open to other countries through Dejima and developed a unique culture that mixes Japanese, Chinese and Dutch elements. The history of the Hidden Christians (who kept their faith in secret) also remains strong.
