According to legend, it was in this year that a fragrant spring gushed from the shrine grounds and that drinking the water could cure diseases, which led the Emperor Seiwa to grant the shrine the name 'Gokogu' (lit. Fragrant Shrine).
伝承によると、この年、境内より良い香りの水が湧き出し、その水を飲むと病が治ったので、時の清和天皇から「御香宮」の名を賜ったという。
