"He will go to Japan in two weeks."

Translation: 他两个星期后会去日本。

Why does the 后 come after 两个星期?

[NasuSamaruk0]

This is the grammatical rule when specifying time. 后 and 前 are the common characters that are supposed to be placed after the specified time.

Playing around with the given English sentence, we have:

• The subject is placed first in the sentence.
• "In two weeks" being placed between subject-and-action, and then worded as "two weeks after".
• The action "will go to Japan" is placed last.

So the worded sentence is literally "He, two weeks after, will go to Japan". Translate, so we have the answer.

Could some one explain why we need 会 in this sentence ? I understood that once the futur is contained in the sentence i.e ”两个星期后“ the verb should not be preceded by 会.

Duolingo is ... special about 会 and 了. It often demands them where native speakers don't.

There are sentences where native speakers do require 会 or 了, but I've given up hope of learning about them from Duo.
