Question:

It kind of confuses me O.o . alot of words seem to have a Kanji form, most from what i've seen. but i looked at some manga that are written in japanese, and some words are in kanji from what i can tell, and some are in hirigana o.o . eh my actually question is(ugh i forgot what else i wanted to ask D: ), in japanese,if your like writing an essay, can you just write everything in kanji o.O ?..... if my question is confusing, let me know.
Thank You :D !

Answer:

No Japanese people can completes any essay without hiragana.
The fact that we can complete the writing in Japanese without any kanji characters means that the basis of Japanese writing is hiragana.
No kanji in Japanese makes it tough read though because it's much harder even for Japanese to know where the start or end of words, you know, hiragana is a continuous form of writing, there's no space in between.
Believe me, it's much easier to read documents with kanji than those written only in hiragana.
Even Japanese people can forget how to read and write Kanji, so when we forget it, then we use hiragana instead.
苺 is usually written in hiragana form in Japan. Kanji sounds more rigid than hiragana to Japanese people. So it's probable that いちご might be used for something like kawaii stuff or somthing like that.
And 苺 can be used for something more formal ones like.....sorry nothing come to my mind.

>is it considered weird to just write in Hirigana?
It's only weird when an adult Japanese person write thing only in hiragana. He/she will be regarded as non-educated or even retard person. However, we also know that learning kanji for foreigners like you is hard so it's no problem for foreigners to write it all in hiragana. We will even admire your effort.
