The word can be written in several ways, each with slightly different connotations. The most common way of writing irezumi is with the Chinese characters 入れ墨 or 入墨, literally meaning to "insert ink". The characters 紋身 (also pronounced bunshin) suggest "decorating the body". 剳青 is more esoteric, being written with the characters for "stay" or "remain" and "blue" or "green", and probably refers to the appearance of the main shading ink under the skin. 黥 (meaning "tattooing") is rarely used, and the characters 刺青 combine the meanings "pierce", "stab", or "prick", and "blue" or "green", referring to the traditional Japanese method of tattooing by hand.

Tattooing for spiritual and decorative purposes in Japan is thought to extend back to at least the Jōmon or paleolithic period (approximately 10,000 BC). Some scholars have suggested that the distinctive cord-marked patterns observed on the faces and bodies of figures dated to that period represent tattoos, but this claim is by no means unanimous. There are similarities, however, between such markings and the tattoo traditions observed in other contemporaneous cultures.

The Ainu people, the indigenous people of Japan, are known to have used tattoos for decorative and social purposes. There is no known relation to the development of irezumi.

Woodblock artists began tattooing.[citation needed] They used many of the same tools for imprinting designs in human flesh as they did to create their woodblock prints, including chisels, gouges and, most importantly, unique ink known as Nara ink, or Nara black, the ink that famously turns blue-green under the skin.
