In Japanese, the word
hōsōshin or
hōsōgami (疱瘡神 (ほうそうしん, ほうそうがみ)) translates literally to "
smallpox god". According to the
Shoku Nihongi, smallpox was introduced into
Japan in 735 into the
Fukuoka Prefecture from Korea. In those days, smallpox had been considered to be the result of
onryō, which was a mythological spirit from Japanese folklore who is able to return to the physical world in order to seek vengeance. Smallpox-related
kami include
Sumiyoshi sanjin. In a book published in the
Kansei years (1789–1801), there were lines that wrote that smallpox devils were enshrined in families which had smallpox in order to recover from smallpox. Smallpox devils were said to be afraid of red things and also of dogs; thus people displayed various dolls that were red. In
Okinawa, they tried to praise and comfort devils with
sanshin, an Okinawan musical instrument, and lion dances before a patient clad in red clothes. They offered flowers and burned incense in order to please smallpox demon. In Okinawa, there was smallpox poetry in
Ryuka; the purpose of smallpox poetry in the Ryukyu language is the glorification of the smallpox demon, or improvement from deadly infection of smallpox. There is a collection of smallpox poetry including 105 poems published in 1805. Traditional smallpox folk dances have been observed even in present-day Japan, including
Ibaraki Prefecture and
Kagoshima Prefecture, for the avoidance of smallpox devils. ==Red treatment==
