Strokes

Definition

将来, 今后, and 以后 are all Nouns, which means “future; from now on, in the future; afterward, later”.

将来, 今后, and 以后, the three words of time all indicate a period of time after a certain moment.

将来 and 今后 indicate the time after the present moment, while 以后 can also indicate the time after a moment in the past.

Moreover, all three words can function as the subject or object, but 将来 sounds more formal and can take an attributive. 今后 is more literary than 以后.

Example

将来, 今后, and 以后 are interchangeable,but with different stress.
将来 is more formal, while 今后 is more literary.
