Origin
Coined in 1882 from Chinese-derived kanji meaning 'gentle way', judo crossed the world through Olympic broadcast and military training, entering dozens of languages unchanged — one of the cleaner cases of deliberate cultural export via sport.
Definition
A Japanese martial art and competitive sport derived from jujitsu, founded by Kanō Jigorō in 1882, based on the principle of using an opponent's force against them rather than opposing it directly, from Japanese 柔道 (jūdō), literally 'gentle way', from 柔 (jū, 'gentle, yielding') + 道 (dō, 'way, path'), the latter from Middle Chinese 道 (daw).
The Full Story

Judo is a compound of two Sino-Japanese morphemes: 柔 (jū, 'gentle, yielding, flexible') and 道 (dō, 'way, path, method'). The term was coined in 1882 by Kanō Jigorō, a Japanese educator and martial artist who founded the Kodokan school in Tokyo, deliberatelydistinguishing his reformed system from the older combat art of jūjutsu (柔術, 'gentle technique'). Kanō replaced jutsu ('technique, art') with dō ('way'), signaling a philosophical shift from battlefield practicality toward moral and mental

When judo debuted as an official Olympic sport at the 1964 TokyoGames, it became one of the few words to enter mass global circulation through a single televised event. Within a decade, national judo federations existed across Africa, South America, and the Eastern Bloc — all using the Japanese word unmodified. The Soviet military had already embedded judo in its close-combat curriculum, and France
or pliant, cognate with nothing in Indo-European but conceptually parallel to Latin mollis. 道 (Classical Chinese dào) is the same root underlying Taoism (道教), meaning path, way, or principle, a core concept in Chinese philosophy from at least the 6th century BCE.
Judo reached English through direct cultural transfer, not trade routes. Japanese-Western contact intensified after Commodore Perry's 1854 forced opening of Japanese ports. Western athletes encountered jūjutsu first; judo followed as Kanō's Kodokan began hosting foreign students in the 1880s–90s. The word appeared in English sporting and diplomatic press around 1889–1905. It was never borrowed through an intermediary European language — it passed directly from Meiji-era Japanese into English as a cultural loanword, carrying its Japanese phonology intact. It is a borrowing, not a cognate of any Indo-European form. Key roots: 柔 (jū / róu) (Sino-Japanese / Old Chinese *ɲɨu: "yielding, soft, flexible, gentle"), 道 (dō / dào) (Sino-Japanese / Old Chinese *duːʔ: "way, path, road; philosophical principle or method"), 柔術 (jūjutsu) (Japanese: "the antecedent combat art ('gentle technique') from which judo was consciously derived and reformed").
