I am new to Japanese, the cool language.

I have done several researches on the language. I have realized that there are 3 or 4 systems that Japanese have. They are hiragana, kanji, katakana and romanji. I may be wrong but correct me if you must.

As of the fact, I just wanted to ask that which system is the first thing to study and memorize from Japanese? Let me know, thanks!
