Yaita Kinbee Kiyosada, the Japanese blacksmith who was ordered to copy and reverse engineer Portuguese matchlock muskets could not make the screw properly himself and had to give his 16-year-old daughter Wakasa in marriage to a Portuguese man in exchange for the Portuguese teaching him to build the muskets. Today Japanese in Tageshima regard Wakasa as a heroine for giving herself to a Portuguese man in exchange for teaching how to screw the end of the musket barrel. A statue was built in her honour as well as candy, restaurants and boast named after her.
