What it is

A matchlock arquebus adopted in Japan after Portuguese castaways reached Tanegashima island and copied within a few years by local smiths. Within decades Japan produced more firearms than any European country, with massive use in the Sengoku wars.

The 1543 date comes from Japanese chronicles (Teppō-ki, 1606) and is cross-checked with Portuguese sources giving 1542-1544; the famous 'three-volley fire' at Nagashino is much questioned by historians.

What it led to

  • Oda Nobunaga's arquebusier tactics (Nagashino, 1575)
  • the unification of Japan under Toyotomi and Tokugawa
  • Japanese castles adapted to arquebus fire
