Keian
Period of Japanese history (1648-1652)
Keian (慶安) was a Japanese era name (年号, nengō; "year name") after Shōhō and before Jōō. This period spanned the years from February 1648 through September 1652. The reigning emperor was Go-Kōmyō-tennō (後光明天皇).
01Change of era
- 1648 Keian gannen (慶安元年): The new era name was created in response to criticism that Shōhō was too closely related to Shōbō (焼亡, meaning "death by burning"). The previous era ended and a new one commenced in Shōhō 5, on the 5th day of the 2nd month.
The new era name was drawn from the Chinese classic, The I Ching: "At the end happiness, joy of quiet righteousness, answer the world unlimited" (乃終有慶、安貞之吉、応地無疆):
