In Edo Period, a hot spring was still primarily a place of remedy, but started to have a face of pleasure according to popularization of travels. In this study, I tried to clarify the diversification of hot springs by paying attention to the information networks among the people who visited hot springs. It was found that there were various kinds of information about hot springs, and they were made and sent by various media. And such information gave influence on the people's choice of hot springs and their behavior pattern there. The information which people collected at hot springs were orally spread, or recorded in their diaries and some were published, and the information cycle was made from the people visited hot springs to the people visiting hot springs.
