Tenbun (天文), also known as Tenmon, was a Japanese era name (年号, nengō, "year name") after Kyōroku and before Kōji. This period spanned from July 1532 through October 1555.[1] The reigning emperor was Go-Heizei-tennō (後平城天皇).[2]

Change of eraEdit

  • 1532 Tenbun gannen (天文元年): At the request of Ashikaga Yoshiharu, the 12th shōgun of the Muromachi Bakufu, the era name was changed because of various battles. The previous era ended and a new one commenced in Kyōroku 5, on the 29th day of the 7th month.
