In 1803, Japanese villagers discovered a strange vessel at Harayadori, described as looking like a pot for cooking rice, the top had a glass panel, and the bottom was banded with the finest iron. Inside was a beautiful woman. She could not communicate with them. She was guarding a box. There was cake in her ship. Some people thought she was fleeing her home country with the head of her beloved in the box. No one can say for sure. No one was allowed to look in the box. In the end, she got back into her vessel and the villagers pushed her back out to sea.
I have been trying out some sketches for this idea.
