The sun goddess hid herself in a cave..

"Japanese Mythology" by Masaharu Anesaki, "Mythology of all Races, vol.8 1928 & 1964
"In the Japanese cosmogonical myth, the sun goddess hid herself for a long time in a heavenly cave in fear of the storm god. 'The source of light disappeared, the whole world became dark,' and the storm god caused monstrous destruction. Gods made terrible noise so that the sun should reappear, and from their tumult the earth quaked. In Japan and in the vast extent of the ocean hurricanes and earthquakes are not rare occurrences; but they do not disturb the day-night succession, nor is there any resulting permanent change in the sky and its luminaries."
