Tanegashima Matchlock (Japanese Arquebus, Tanegashima)

Timeline

1. 1543–1545Tanegashima · KyushuIn 1543, two Portuguese adventurers (arriving aboard a Chinese trading vessel) sold matchlocks on Tanegashima to the island lord Tanegashima Tokitaka. The lord bought two and immediately ordered swordsmith Yaita Kinbei to copy them. Kinbei and subsequent craftsmen solved the key problems of barrel welding and powder-chamber sealing in extremely short time, successfully producing Japan-made matchlocks — teppō. The speed of this technology transfer was a rare case worldwide at the time.
2. 1550–1575Nagashino (present-day Shinshiro, Aichi Prefecture) · HonshuAfter the matchlock's introduction it spread rapidly among daimyō across the land, with Sakai (Osaka Prefecture) becoming the most important production center. At the Battle of Nagashino in 1575, Oda Nobunaga concentrated some three thousand gunners using rotating-volley tactics to rout the Takeda cavalry, demonstrating the strategic value of massed firearms use and regarded as a turning point in Japanese military history. Gun output then expanded sharply, with domains competing to recruit gunners.
3. 1621–1630Edo (present-day Tokyo) · HonshuBetween 1621 and 1630 the Tokugawa shogunate continued advancing the sword-hunting edicts and the sakoku system: casting and possessing firearms required shogunate permission, and output was concentrated in shogunate-designated arsenals (mainly in Kunisō, Sakai, and elsewhere). By monopolizing firearm production the shogunate maintained political stability and prevented provincial daimyō from accumulating military advantage. Meanwhile, lacking external technological stimulus, the design of the Tanegashima matchlock saw almost no improvement during this period, forming the historically famous phenomenon of 'technological freeze,' in stark contrast to Europe's flintlock revolution.
4. 1850–1868Japan · JapanAfter the arrival of the Black Ships in 1853, the shogunate and domains recognized the severity of the gap in firearms with the West and began secretly importing Western rifles. After the 1868 Meiji Restoration, the Japanese military fully re-equipped with Western rifles and artillery; the Tanegashima matchlock exited the military stage, but its historical status as a tool of 250 years of feudal political control, and the war revolution it triggered in the 16th century, remain highly regarded in military history scholarship.
