The first documented introduction of the matchlock which became known as the "tanegashima" was through the Portuguese in 1543. The "tanegashima" seems to have been based on snap matchlocks that were produced in the armory of Malacca in Portuguese Malacca, which was captured by the Portuguese in 1511. The name "tanegashima" came from the island where a Chinese junk with Portuguese adventurers on board was driven to anchor by a storm. The lord of the Japanese island Tanegashima Tokitaka (1528–1579) purchased two matchlock muskets from the Portuguese and put a swordsmith to work in copying the matchlock barrel and firing mechanism. Within a few years the use of the "tanegashima" in battle forever changed the way war was fought in Japan. From 1560, firearms were used in large battles in Japan. In his memoirs published in 1614, the Portuguese adventurer turned author Fernão Mendes Pinto placed himself in that first landing party, although this claim has been roundly discredited and in fact contradicts his claims to be simultaneously in Burma at the time. However, Pinto does appear to have visited Tanegashima soon thereafter.
