Reconstruction:Proto-Japonic/turu

The core meaning appears to be vine; line; string as a noun, and to hang down, as a line or string; to form or take the shape of a line or string (both transitive and intransitive) as a verb.

Cognate with *tura (“vine; line, string; line (of things), queue, procession”).

Vovin (2008) considers it possibly related to an ancestor of Korean 두루미 (durumi, “crane”), with a root-final -m vanishing later, leaving only a Kansai accent pattern behind.[1] May ultimately be a regional Wanderwort. Compare also Proto-Turkic *durunja (“crane”) (whence Turkish turna), Mongolian тогоруу (togoruu, “crane”), Hungarian daru (“crane”). (Can this⁽⁺⁾ etymology be sourced?)
