The folktale “The Family that Sank in the Water" was narrated by a female speaker of Kolyma Yukaghir, Akulina Vasilievna Sleptsova. Sleptsova was born in the village of old Nelemnoe, in the Sakha (Yakutia) Republic of Russia. The folktale was recorded and transcribed in August 2006 during my fieldwork in the village of Nelemnoe. I corrected the transcription in 2008 with the help of Dar'ja Petrovna Borisova, a younger speaker of this language. The whole text is given in Section2; the morphological analysis of the text and Japanese translation are given in Section 3.
