Katakana

Katakana characters are more angular than their hiragana counterparts and are used for words of foreign origin, emphasis and a whole bunch of swearwords.

W

The character listed as wu on the chart is actual pronounced and romanized as n. Si, ti, tu, and hu are all pronounced and romanized as shi, chi, tsu, and fu respectively. The above hiragana characters are all called the unvoiced characters. They are called this because the sounds resonate in a spot in your throat that isn't very far down. There are more characters that are called the voiced characters. These resonate in a spot that's deeper down. To make these characters, you simply add 2 little lines or a circle to the characters from above. Ks then becomes Gs, Ss becomes Zs, Ts become Ds, and Hs become Bs or Ps.

In this chart, both zi and di are actually ji and d is usually written as zu, although it is sometimes romanized as dzu.
