::summary Period of Japanese history (1648–1652) ::
Keian was a Japanese era name after Shōhō and before Jōō. This period spanned the years from February 1648 through September 1652. The reigning emperor was Go-Kōmyō-tennō.
Change of era
- 1648 Keian gannen: 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):
Events of the ''Keian'' era
- April 1, 1649 (Keian 2, 20th day of the 2nd month): There was a major earthquake in Edo.
- 1651 (Keian 4): Keian Uprising. Plans by well-organized rōnin to attack several Tokugawa strongholds simultaneously were timely discovered. The attempt plan to overthrow the Edo Bakufu by Marubashi Chūya and Yui Shōsetsu was thwarted.
- 1652 (Keian 5, 5th month): Nihon Ōdai Ichiran is first published in Kyoto under the patronage of the tairō Sakai Tadakatsu, daimyō of the Obama Domain of Wakasa Province.
