Hiragana is used to write native Japanese words or to spell words or part of words that don’t have their own Kanji symbol. Kanji symbols are the busy looking characters derived from Chinese. Katakana is used mainly to write foreign words that have made their way into Japanese.
Hiragana and Katakana each consist of 46 basic symbols which can be modified slightly to cover every syllable you need. A lot of Hiragana symbols resemble Katakana symbols so you are already on your way to mastering that too.
