How do you say I'll talk to you later?
How do you say formally and informally I'll talk to you later in Japanese

Question

Answer

"じゃまた"　"またあした"　"またね"   And the "ne" works at the end of either of the first two. 
"Ja mata"  "mata ashita"   "mata ne"
I'm not too sure about a formal setting. Though, またあした would be the most formal of the three.
It translates to "again tomorrow?" じゃまた to "well then, again?" and またね "Again, right?"

Answer

あとでね。

では後程。（では　のちほど）
