embassy to Europe (Tenshō Ken'ō Shisetsu) sailed from Nagasaki, and its members would not return until 1590. It headed by Mancio Itō and organized on the initiative of Alessandro Valignano. Although less well-known and less well-documented than Hasekura Tsunenaga's diplomatic mission to the Vatican (known as the "Keichō Embassy") in 1613–1620, this historic diplomatic initiative remains a noteworthy accomplishment. The mission is sometimes referred to as the "Tenshō Embassy" because it was initiated in the Tenshō era. This venture was organized by three daimyōs of Western Japan – Ōmura Sumitada, Ōtomo Sōrin and Arima Harunobu. 1583 (Tenshō 11, 4th month): Battle of Shizugatake. 1584 (Tenshō 12, 4th month): Battle of Komaki and Nagakute.

December 17, 1586 (Tenshō 14, 7th day of the 11th month): Ogimachi gave over the reins of government to his grandson, who would become Emperor Go-Yozei. There had been no such Imperial since Emperor Go-Hanazono abdicated in Kanshō 5. The dearth of abdications is attributable to the disturbed state of the country and to the fact that there was neither any dwelling in which an ex-emperor could live nor any excess funds in the treasury to support him. 1586 (Tenshō 14, 12th month): A marriage is arranged between the youngest sister of Hideyoshi and Tokugawa Ieyasu. 1586 (Tenshō 14, 12th month): The kampaku, Toyotomi Hideyoshi, was nominated to be Daijō-daijin. 1586 (Tenshō 14, 12th month): An earthquake strikes the Chubu region, killing 8,000 people. 1587 (Tenshō 15): Gold or silver coins called Tenshō-tsūhō were minted. The gold coins (Tenshō-ōban) weighed 165 grams; and these oval shaped coins were worth 10 ryō. 1588 (Tenshō 16, 7th month): Emperor Go-Yōzei visits Toyotomi Hideyoshi's mansion, sword hunt decree 1590 (Tenshō 18, 7th month): Hideyoshi led an army to the Kantō where he lay siege to Odawara Castle. When the fortress fell, Hōjō Ujimasa died and his brother, Hōjō Ujinao submitted to Hideyoshi's power, thus ending a period of serial internal warfare which had continued uninterrupted since the Ōnin era (1467). 1592 (Tenshō 20, 4th month): The Imjin War begins with the Siege of Busanjin. In 1589–1590 (in the 23rd year of the reign of King Seonjo of Joseon), a diplomatic mission led
