Oto-hime or Otohime (Japanese:乙姫), in the Japanese folktale of Urashima Tarō, is the princess of the undersea palace Ryūgū-jō.
Second daughter

Oto-hime (Princess Oto)'s name consists of the character also read otsu meaning "No. 2". Thus Oto-hime must have been the 'second daughter' or 'younger princess' of the Dragon King (Ryū-ō), as explained by folklorist Yoshio Miyao[ja] in his bilingual edition of the In Urashima fairytale. Miyao whimsically wonders whatever became of Kō-hime, the elder daughter never mentioned.
