Japan here I come! in Japanese?

How does one write 'Japan here I come!' in Japanese?

Hi : )

Your question is difficult. An answer of the question will vary for each situation.

Do you assume what situation? Please showing, ok?

Thank you.

Just as a post on my FB page so that all my Japanese friends will know! :)

Are you a male or a female, and are you going to write once you've arrived in Japan, or when you are about to leave your country to Japan? (Believe me, that makes a difference...)

Thank you for your addition of the situation :)
It makes sense.
You have a plan to visit Japan. don't you?

(1)nihon ni ikuyo（日本に行くよ）.

notes:
-This phrase near to "I go to Japan." in an English nuance.
-This phrase had a calm atmosphere.

(2)kondo nihon ni ikuyo （今度、日本に行くよ）.

notes:
This is near to "I plan to go to Japan." in an English nuance.
This phrase had a calm atmosphere like the (1).

(3)kondo nihon ni ikuze!! （今度、日本に行くぜ）.
-This is near to "I will go to Japan.(it shows a slight excitement)" in an English nuance.
-This phrase had an atmosphere excitedly.
-This phrase is used by the male.

(4)iza nihon he (いざ日本へ!)
notes:
-This is near to "I'm going to leave Japan now." in an English nuance.
-This phrase had a pleasant atmosphere.

Lots of expressions in a language can't be translated in other languages
A typical example: in the US an important person is called "a big cheese" ...in French a big cheese is just a big cheese..

An important person in French is "un grand homme" (a big man, even if he is 4 ft tall) BUT this is usually used when that person is dead..

Colloquially it is "un grand mec"..but wouldn't be used in front of that person..

Thank you all for your help!! :)

My trip is in November and I can't wait!

Have a nice trip : )
