Naginatajutsu is the Japanese martial art of wielding the naginata (長刀). The naginata is a weapon resembling the European glaive and the Chinese guan dao. Most naginatajutsu practiced today is in a modernized form, a gendai budō, in which competitions also are held.

Bōgu , properly called kendōgu , is training armour used primarily in the Japanese martial art of kendo, with variants used for jūkendō, tankendo, and naginata.
