When Did the Portuguese Arrive in Japan? 1543 — Tanegashima Changes Everything

1543. Three Portuguese traders — António Mota, Francisco Zeimoto, António Peixoto — blown off course aboard a Chinese junk, washed ashore on Tanegashima (south of Kyushu).

What They Brought

• Arquebuses (matchlock guns) — first firearms in Japan.
• Gunpowder knowledge.
• Tobacco, tempura technique, new textiles.

Immediate Impact

• Tanegashima lord Tokitaka bought two guns, ordered swordsmiths to replicate.
• Within a decade: 300,000+ arquebuses produced — more than any European army.
• Transformed Sengoku warfare (Oda Nobunaga’s 3,000 gunners at Nagashino, 1575).

Beyond Guns

• Nanban trade (1543–1639) — Portuguese carracks from Macau/Goa.
• Jesuit missions (Francis Xavier, 1549) — Christianity spreads fast.
• Cultural imports: tempura, kasutera (castella cake), konpeitō candy, bidama (marbles), buttons, playing cards.

The End

1639: Shogunate expels Portuguese, bans Christianity, seals Japan (sakoku). Only Dutch (Dejima) and Chinese (Nagasaki) remain.

But that 1543 landing? It rewired Japanese history.
