Question: what is dozo in japanese?
Answer: Dozo means “go ahead” or “go first.” While some words are shortened to make them easier to say (“arigatou gozaimasu” becomes “arigatou”), dozo is often lengthened to “hai-dozo” as if it were one word (Yes-go-ahead). Other times, to be insistent that someone go ahead of you, there is the very handy dozo-dozo.
