Today, Thursday in the afternoon, the 16th of the month of December of the year 1610, at 6 o'clock, was when perhaps as many as nineteen people from Japan, China, arrived and entered here in the city of Mexico. A noble, their lord, the ambassador, from the court of the great ruler the emperor of Japan, who brought them, came to make peace with the Christians so that they would never make war but always be at peace and esteem each other, so that Spanish merchants will be able to enter Japan and none of the people there will be able to impede them. And likewise the people of Japan will be able to come enter New Spain to do business, to come here to sell goods that are made there, and no one here will be able to impede them, for thus the lord Viceroy don Luis de Velasco, Marqués of Salinas, whom they came to see, informed themChimalpahin diary, "Annals of his time" 16 December 1610, p. 171.
