The waves are gathered on the shore of Sumi Bay, and in the gathered night, when in dreams I go to you, I hide from people's eyes (Kokin Wakashu (A Collection of Ancient and Modern Japanese Poetry), Hyakunin Isshu (one hundred waka poems by one hundred poets) 18).
すみの江の岸による浪よるさへや夢のかよひぢ人目よくらむ（古今和歌集、百人一首18、）
