First edition of an important Jesuit work, publishing for the first time the annual letters of 1589 and 1590 reporting on the situation in Japan, written by the Jesuit missionaries Alessandro Valignano in "Cansuca" (Katsusa in Kyushu) on 7 October 1589 (pp. 3-42), and Luís Fróis in Nagasaki on 12 October 1590 (pp. 43-125). They provide valuable information on the Jesuit missions in Japan and elsewhere in Asia as well as on the daily life, customs and political situation. This includes the establishment and development of Jesuit residences, churches and colleges, along with other activities, in Katsusa, Arima, Omura, Nagasaki, Bungo and many other cities and regions. Valignano wrote from the newly established Jesuit college at Katsusa, where in the following year he brought in a printing press from Macao and set up the first Jesuit printing office in Japan, publishing its first efforts in 1591.
The Portuguese Jesuit missionary Luís Fróis (1532?-1597) joined the Jesuits and worked from 1548 at Goa, where he succeeded Gaspar Berse. His first attempt to reach Japan failed in 1554, but he finally succeeded in 1563 and became one of the first Europeans to gain a deep knowledge of Japan and its culture.
