When writting Japanese, when do I use hiragana, kana and Kanji?

Question

Are there specific parts of a sentence where I should use a particular one?

Answer 1

you need to study hiragana first. then study katakana and kanji.
you can use only hiragana to write if you dont know any kanji.

katakana = katakana are most often used for transcription of words from foreign languages. For example, "television" is written "terebi"
kanji = kanji are used to write parts of the language such as nouns, adjective stems and verb stems, while hiragana are used to write inflected verb and adjective endings (okurigana), particles, native Japanese words, and words where the kanji is too difficult to read or remember.
hiragana =
japanese children first learn hiragana and katakana and are gradually introduced to kanji. hiragana and katakana represents the same 47 syllables, and the alphabets are used together with kanji in writing modern japanese.
there are more than 60,000 kanji, but most people have a general knowledge of from 3,000 to 4,000 kanji. to simplify matters, most books and newspapers use only 1,850 kanji-the same number high school graduaters are expected to master.
Furigana are a Japanese reading aid. They consist of smaller kana printed next to a kanji or other character to indicate its pronunciation. In horizontal text, yokogaki, they are placed above the line of text, while in vertical text, tategaki, they are placed to the right of the line of text. They are one type of ruby text.
Furigana are most commonly used in works for children, who may not have sufficiently advanced reading skills to recognise the kanji, but can understand the word when written onetically in hiragana. Because children learn hiragana before katakana, in books for very young children, there are hiragana furigana next to the katakana characters. It is common to use furigana on all kanji characters in works for young children.
In works aimed at adult Japanese speakers, furigana may be used on a word written in uncommon kanji.
Furigana commonly appear alongside kanji names and their romanizations on signs for railway stations, even if the pronunciation of the kanji is commonly known. Furigana also appear often on maps to show the pronunciation of unusual place names.

Answer 2

um, if u good at hiragana, katakana, kanji u can use 3 kinds in one sentence.

the using them depend on ur ability. u can use them anywhere in sentence u want , but shound remember:

-hiragana is used mostly for verb , particle...

-some hiragana pronounce the same but the meanings diffrent so u need write them by kanji . In sentence , u use kanji that judge writing skills of urs . Using kanji make sentence shorter and easier to understand.

-katakana almost is noun , cant replace them by hiragana or kanji when saying the things that Japanese use them to record foreign sounds ( like "computer, radio...")
if u use english often so easy to remember them. Sometimes when forget the ways of saying for something in hiragana, u can use katakana. (like "uwagi" = "kooto" [coat] )
( some katakana meaning = hiragana meaning )

Answer 3

You can use whatever you want, whenever you want. By convention, kanji are used when they are available and well known, hiragana is used when kanji are not available or not well-known, and katakana are used for foreign words that are obviously recognizable as foreign.
