Talk:野ざらしの首、鬼ヶ島にて (Nozarashi no Kubi, Onigashima Nite)/@comment-76.177.212.73-20180610034956/@comment-26239285-20180610115948

In Japanese Wikipedia, both 著物 and 着物 redirect to an article on Japanese clothing and in weblio 著物 is listed as kimono but no further details are added. Plus a google image search for 著物 shows people in kimonos. I would guess that 著物 is a literary or other variant.

Since various secondary sources (Vocaloid and Evillious wikis, translator's web page) list the first occurrence of the word as著物, I wouldn't change it without confirming primary sources (i.e. the physical album if it has printed lyrics) first.
