Tenshō (天正) was a Japanese era name (年号, nengō, "year" name) after Genki and before Bunroku.
This period spanned the years from July 1573 through December 1592 during the Senguoku era.
The previous era ended, and a new one commenced in Genki 4, the 28th day of the 7th month.
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.
[20] The fictional plot of the classic Akira Kurosawa film Seven Samurai takes place in the 15th year of Tenshō.
