...In addition, attention should also be paid to headgear during mourning and funerals. If one went out during the 49-day (hon'imi) period, it was customary to wrap one's head in white cotton cloth, which was called "tento osekore." Men who were taboo at funerals would place triangular pieces of cloth or paper on their foreheads, which were called "kanmuri," "kamieboshi," "shihou," "kamikakushi," "mikakakushi," or "manji no nun," or wear a headband made of white cloth, or wear a woven hat made of rush grass, which was called "kichugasa." This was a custom in various places. It was also widely accepted throughout the country that women would wear special topknots called "irogami," "ureigami," "kichushimada," or "kichumage," or would cover their bodies from the head up with hemp kimonos, thin white silk kazuki, or plain white kimono short sleeves called "katsugi," "irokatsugi," "ino-kaburi," or "kaburi-katabira," or would wear the left sleeves of such kimonos over their heads called "sode-kaburi," or would wear white cotton hats, sleeve-shaped cloth, or hand towels called "wata-boushi," "kaburi," or "iro" when joining funeral processions. Mourning clothes have changed with the changing concept of mourning.
