After the 12th century, Urashima Monogatari appeared in books about waka poetry such as "Toshiyori Zuino" (Toshiyori's Poetic Essentials), "Ogisho," and "Waka domosho" (a waka handbook for beginners), and they were written in kana (the Japanese syllabaries), being widely read among nobles in the imperial court.
12世紀以降になると、『俊頼髄脳』をはじめ『奥儀抄』、『和歌童蒙抄』など歌論書に浦島物語が登場し、仮名で書かれ宮廷や貴族達の間に浦島物語が広く浸透した。
