In polite speech, the question mark is often replaced by the particle か.
Usage
Simply add か to the end of a polite sentence. No question mark is strictly necessary in traditional writing, though the modern period or ? is often used.
行きましたか。Did you go?
これは何ですか。What is this?
映画を見ましたか。Did you watch the movie?
Casual Questions
In casual speech, do not use か to ask yes/no questions. It can sound surprisingly sarcastic or harsh. Instead, just raise your intonation.
食べる?Will you eat? ↗
行く?Are you going? ↗
分かった?Did you understand? ↗
