This article explores the history, etiquette, and social acceptance of wearing a ponytail in Japan. Ponytails have been popular hairstyles throughout Japanese history, with evidence showing that they were worn by both men and women during the Heian period (794-1185). It is generally considered inappropriate to wear your hair up in a ponytail at formal occasions such as weddings or funerals; instead it should be worn down or tied back into a low bun. Workplace policies on ponytails can vary depending on the company and industry, with most companies having strict rules against wearing overly casual hairstyles while at work. The cultural impact of ponytails in Japan may vary due to historical associations with samurai warriors; however there appears to be quite an even split between those who accept wearing them versus those who do not approve.
