The Tango region of northern Kyoto Prefecture. Here, traces of human interactions mediated by the sea can be found everywhere. Many excavated artifacts which can be considered as evidence for this have been discovered in ancient ruins and burial mounds. Such traces aren’t limited to things from ancient times, nor to physical objects. Even as eras change, it is possible to also find those traces in tales and festivals related to Shinto and Buddhism. I would like to introduce some examples of that here.
