Japanese martial arts

The martial arts developed or originating in Japan are extraordinarily diverse, with vast differences in training tools, methods, and philosophy across innumerable schools and styles. That said, Japanese martial arts may generally be divided into koryū and gendai budō based on whether they existed prior to or after the Meiji Restoration, respectively. Since gendai budō and koryū often share the same historical origin, one will find various types of martial arts (such as jujutsu, kenjutsu, or naginatajutsu) on both sides of the divide.
