Bujutsu is a compound of the roots bu (武) meaning war or martial and jutsu (術) meaning technique.
Budō is a compound of the roots bu (武) meaning war or martial and dō (道) meaning path or way,
Budō translates as “martial way” or “the way of war” but bujutsu is translated as “science of war” or “martial craft”.
Therefore, a valid translation of ‘bujutsu‘ is: “Martial Science”
Just sayin…
