The term dojo (kanji: 道場) means "martial arts hall/studio" in English. It is written どうじょう in hiragana. It may also be rendered in English as dōjō , doujou , dojyo , dōjyō or doujyou. It's pronounced roughly like "doe-joe", rhyming with the word "mojo".
This refers to the hall where not only sword fighting but any martial art may be engaged in. 道, do, means way or skill and is the same do used in kendoKENDO 剣道 "the way of the sword" learn more..., iaidoIAIDO 居合道 "art of drawing a sword" learn more..., aikidoAIKIDO 合気道 "way of gathering energy" learn more..., etc. In the Japanese reading, it is pronounced michi, which means a literal road or path. The figurative use is not uncommon, as when we speak of the path of life; there is a frequently used phrase, waga michi wo yuku, 我が道を行く, which means “[I will] go my own way [in life].”
場, by itself, has the Japanese reading of ba and means place. It is seldom used on its own, but you will find it in common Japanese phrases like sono ba (その場), which means “right there.”
