Sado is known as much for its unblemished natural beauty as for its melancholy history. Revolutionary intellectuals, such as the Buddhist monk Nichiren, were banished to Sado to endure harsh exile as punishment for treason. When gold was discovered on Sado during the Edo period (1603-1868), the homeless and poverty-stricken were sent to Sado to work as forced laborers in the mines. This long history of hardship has left a tradition of soulful ballads and folk dances. Even the bamboo grown on the island is said to be the best for making shakuhachi, the flutes that accompany the mournful music.
May through September is the best time to visit Sado. In January and February the weather is bitterly cold, and at other times storms can prevent sea and air crossings. Although the island is Japan's fifth largest, it's still relatively small, at 530 square km (331 square mi). Two parallel mountain chains running along the north and south coasts are split by a wide plain, and it is here that the island's cities are found. Despite the more than 1 million tourists who visit the island each year (more than 10 times the number of inhabitants), the pace is slow.
