Two symbols for each letter in both Hiragana and Katakana?

Question:

What do each mean? is it the upper/lower case distinction? or is it something else? And which would be which if this applied? And I'm not talking about noth of katakana and hirgana, I'm talking about each one having two for each, so that would be 4 symbols for each sound.

This is what I mean: http://www.ispeakjapanese.net/wp-content…

Thank you for the help

Answer:

No upper and lower case. The link you gave shows katakana and kanji, no hiragana there.
There are three writing systems in Japanese; kanji, hiragana and katakana. The sounds in the hiragana and katakana syllabaries are identical, they are just used for different things. Katakana is used for 'foriegn' names and words used in Japan.
