Yatate (矢立) are small personal smoking-pipe-shaped writing sets from medieval Japan which provided a carrying box for the ink cotton, and a shaft for a brush (and possibly a letter opener).

This particular item is very unusual in the fact that it is shaped like a matchlock rifle . Also Known as a Tanegashima (種子島), most often called in Japanese and sometimes in English hinawajū (火縄銃, "matchlock gun"), was a type of matchlock configured arquebus firearm introduced to Japan by the Portuguese traders in 1543.
