Visits to the Palace of the Sea God in Ancient and Medieval Japan.

Visits to the palace of the sea god are a recurring theme in premodern Japanese narratives, and comparing these stories across time periods reveals shifting perceptions of the supernatural world. The earliest sources for narratives of travel to the palace of the sea god in Japan date from the eighth century, most notably in the stories of Luck of the Mountain and Urashima Tarō. In these stories, the descriptions of the sea god's palace, the relationship of the sea god to the natural world, and even the location of the palace were tied to eighth-century understandings of kingship, weather, and geography. Later adaptations of these stories incorporate features of Buddhist geography, Chinese architecture, Buddhist narrative motifs, and even an alternative vision of supernatural time. These alterations occurred because the eighth-century narratives required adaptation to fit a new political, social, and religious reality. This comparison demonstrates that our vision of the supernatural world is inextricably tied to our understanding of the natural. When our fundamental grasp of the nature of reality changes, our imagination of the supernatural transforms in turn. [ABSTRACT FROM AUTHOR]
