Oki Islands
Tokoyo is a figure in Japanese mythology. She was the daughter of a samurai named Oribe Shima. Shima had displeased the Emperor, who was in an ill state of health, and was subsequently banished. As a result, he had to set up home on a group of islands called the Oki Islands, away from his daughter. Both he and Tokoyo were miserable at being separated, and she became determined to find him. She sold all her property, and set out for a place called Akasaki, which was just off the coast from the Oki Islands. Although she asked the fishermen to ferry her there, they all refused, since it was forbidden to visit anyone banished there.
