How do you say how was your day in Japanese?

Answer 1

There are two common ways of asking "how was your day?" in Japanese. These are: 今日はどうだった？ (kyou wa dou datta) and 今日はどんな一日だった？ (kyou wa donna ichinichi datta). I believe that the first option is more common, but either should suffice.The above sentences should be used only when talking to close family or friends. In the case of a superior or someone of a higher status than your own, you should use the more polite versions which are 今日はどうでしたか (kyou wa dou deshita ka) and 今日はどんな一日でしたか (kyou wa donna ichinichi deshita ka).

Answer 2

I would say "(their name) no hi WA ikaga deshita ka." which is polite.

Other possibilities:

kyou WA dou deshita ka.

lit: How was today?

kyou WA yokatta deshita ka.

was today good?
