How do you say "This is my first time visiting Japan" in japanese?

Question:

Instead of just giving the translation by itself, can you please give the translation and break it down word from word? That would help a lot! Thank you to all that answers :)

Answer:

初めての日本訪問です。
hajimete no nihon houmon desu.
初めて （HAJIMETE) ― first
日本 （NIHON ）― Japan
訪問 (HOUMON）― visit

OR

日本にきたは初めてです。
nihon ni kita wa hajimete desu.
First time coming to Japan.

In Japanese, words like "I" or "this" are not needed in most cases.
