The first time that the Yukatchu's weapons were confiscated was during the reign of King Shō Shin (1477–1526), who centralized the Ryukyu Kingdom by forcing the Aji to leave their respective Magiri and move to Shuri. He confiscated weapons from commoners and Yukatchu who weren't part of the Ryukyuan military to lower the possibility of rebellion. The second time that the Yukatchu were disarmed was after the invasion of 1609 by Satsuma Domain, which prohibited the carrying of weapons by the Yukatchu.
