Glossary Timeline

Tenshō (天正) was a Japanese era name (年号,, nengō,, lit. "year" name) after Genki and before Bunroku. This period spanned the years from July 1573 through December 1592.^[1] The reigning emperors were Ōgimachi-tennō (正親町天皇) and Go-Yōzei-tennō (後陽成天皇).^[2]

Change of era

• 1573 Tenshō gannen (天正元年): The new era name was created to mark a number of regional wars. The era name was inspired by a passage from a Chinese classic, Lao Zi:  :"Those who are at peace with nature bring all under Heaven into its correct pattern" (清静者為天下正).

The era name Tenshō was suggested by Oda Nobunaga. The previous era ended and a new one commenced in Genki 4, the 28th day of the 7th month.

Events of the Tenshō era

• 1573 (Tenshō 1, 7th month): Ashikaga Yoshiaki lost his position as shogun. He shaved his head, becoming a Buddhist priest. Initially, he took the priestly name Sho-san; but he eventually came to be known as Rei-o In.^[3]

The Tokugawa defended the castle; and Tokugawa Ieayasu sought assistance from Oda Nobunaga. In response, Nobunaga and his son Nobutada arrived at Nagashino with a large force. In the ensuring Battle of Nagashino, the Takeda attackers were forced to retreat.^[4]

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,^[10] 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 daimyo of Western Japan -- Ōmura Sumitada, Ōtomo Sōrin and Arima Harunobu.^[11]

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.^[15]

• 1592 (Tenshō 20, 4th month): The Imjin War begins with the Siege of Busan.

In 1589-1590 (in the 23rd year of the reign of King Seonjo of Joseon), a diplomatic mission led by Hwang Yun-gil was sent to Japan.^[18] The Joseon ambassador was received by Hideyoshi.^[19]

In popular culture

The fictional plot of the classic Akira Kurosawa film Seven Samurai takes place in the 15th year of Tenshō.
