I find your technique very dubious. I recommend a more organized system of Japanese study.

Kanji is chinese. But they make the students learn in it japanese schools

I am very confused about your title "sentence structure in kanji." Kanji is one of the three systems of writings in Japanese. Many of the hiragana words can be written in kanji form. However, I wouldn't worry about the kanji until you have become more proficient in basic Japanese. After that you could gradually start learning kanji. Just make sure you don't start with difficult kanji such as 綺麗 before you learn kanji such as 山.

How about throwing the guy some suggestions? If you want a quick and dirty grammar book, try Barron's Japanese Grammar. For it's size it is pretty good for the beginning/intermediate student. Decide on a text book series to use. A couple of the best are the Yookoso! and Genki series. There are plenty of kana (hiragana & katakana) study sources out there. If you buckle down, it should take no more than a weekend to master it. If at all possible, do not study Japanese in romaji. Get away from it as soon as possible and move on to kana study materials. You need to have a firm understanding of grammar before jumping into kanji. Good luck!

Kanji comes from Chinese, but is not Chinese. Characters were adapted, but meanings and pronunciations are very different.

Good advice, Derek. I wouldn't push yourself to learn hiragana and katakana in a weekend. You should be able to do it in a few weeks, though.

Actually, it really does make it hard to understand. Also, a spell check would help us out too. Didn't, not dident. I'm not trying to be an A**H**, really, I'm not. Listen, Japan is the most literate country in the world. Might as well get used to writing clearly now so your JAPANESE is better later.

Kanji particles: NO
Adj.: Just like english

not that I wanna sound pedantic or anything, but the article used there is HA (は)

Learning kanji on your own is fine, but I would definately recommend you learn Japanese as a language with a teacher before you get too involved with the written styles - it will only seem backwards and confusing otherwise (trust me, I know from personal experience lol)

You know , its hard to master the structure of Kanji, I mean sometimes they can write a series of kanji without any particle or anything. like they make up new words. I just dont get it even thought I am Chinese.

Yeah, you see those expecially for like goverment titles and offices or stuff like this: 地下水汚染対策事例集.
