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
Urashima and Otohime cross a bridge in the kingdom under the sea. Japanese painting, late 16th or early 17th century
Oto-hime (Princess Oto)'s name consists of the character also read otsu meaning "No. 2".[a][1] 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.[1] Miyao whimsically wonders whatever became of Kō-hime, the elder daughter never mentioned.[2]
Explanatory notes
^This is otsu as in the
stock phrasekōotsu meaning "No. 1 and No. 2", as Miyao explains. Further explanation: kō and otsu are the first two of ten
heavenly stems, which combined with the twelve
earthly branches (
Chinese zodiac) complete the
Sexagenary cycle system. The kō can also be read as "ki-no-e", and otsu as "ki-no-to", literally "wood-elder" and "wood-younger"; thus each stem is a combo of the five elements and either yang/ying.
