Great place to start would be Hiragana! Then Katakana. 

Start learning basic nouns to get your foot in the door as well as some basic phrases. :)

Feel free to contact me with any questions you have!

-Hiragana

-Katakana

(If you are serious about it because you want to live there or something:

-Remembering the Kanji 1)

-Genki or another textbook

-Watching a lot of anime/translating songs, or something like that.

That's all.
