School #9 of 10 in our series. Ono-ha Ittō-ryū is the oldest surviving branch of Ittō-ryū — official sword school of the Tokugawa shogunate, founded by a man who won a duel to the death to inherit it. Still teaching in Tokyo under its 18th headmaster, in an unbroken line, today.

School #8 of 10 in our series. Kashima Shinden Jikishinkage-ryū’s 8th headmaster, Naganuma Kunisato, pioneered the first standardized bōgu armor and shinai in Japanese martial arts history — the direct ancestor of every piece of kendō equipment used today. The gravestone inscription proves it.

Hyōhō Niten Ichi-ryū

School #6 of 10 in our series. Miyamoto Musashi fought over 60 duels and never lost. He built a two-sword school that defied every convention of Japanese swordsmanship — and wrote The Book of Five Rings while dying of cancer in a cave. Hyōhō Niten Ichi-ryū carries that legacy today, four centuries later.
