Kōji (弘治?) was a Japanese era name (年号, nengō,?, lit. "year name") after Tenbun and before Eiroku. This period spanned the years from October 1555 through February 1558.[1] Reigning emperors were Go-Nara-tennō (後奈良天皇?) and Ōgimachi-tennō (正親町天皇?).[2]
Change of era
- 1555 Kōji gannen (弘治元年?): The era name was changed to mark an event or a number of events. The old era ended and a new once commenced in Tenbun 24.
The name originates from the following Chinese passage: 「祇承宝命、志弘治体」.
Events of the Kōji era
- 1555 (Kōji 1, 1st month): A border war began between Mōri Motonari, daimyo of Aki Province, and Sue Harutaka, daimyo of Suō Province.[3]
- 1555 (Kōji 1, 11th month): The Mōri forces surrounded the Sue defenders in the Battle of Itsukushima. When the outcome of the battle became clear, Sue Harutaka committed suicide; and others, including Odomo-no Yoshinaga, followed Harutaka in suicide. This victory, and the subsequent consolidation of the Mōri holdings were owing to Motonari's four sons: Mōri Takamoto, Kikkawa Motoharu, Hoda Motokiyo, and Kobayakawa Takakage.[3]
- 1555 (Kōji 1): The forces of Takeda Shingen and Uesugi Kenshin met at the confluence of the Saigawa and te Chikumagawa in Shinano province; and the fighting was known as the Battle of Kawanakajima.[4]
- 1556 (Kōji 2): The Ōmori silver mine fell into the control of the Mōri clan during a campaign in Iwami province.[5]
- September 27, 1557 (Kōji 3, 5th day of the 9th month): Emperor Go-Nara died at age 62.[3]
