Congratulations! If you've finished all of the hiragana writing lessons up to this point, you have all of the basic hiragana down. There are still a few more sets of hiragana to work on, but they are made up mostly of the kana you have already learned.

The first set of these is the dakuon set. These are the voiced versions of some of the sounds that you have already learned. The only difference in writing the kana is that the voiced version gets a set of dakuten (also called nigoriten) added to it. Dakuten look like straightened quotation marks.

The k, s, t, and h rows of the hiragana table can take the dakuten.

When the dakuten are added to the k row (ka ki ku ke ko), the k sounds become g sounds (g as in gum).

When the dakuten are added to the s row (sa shi su se so), the s sounds become z sounds except for shi, which changes to ji.

When the dakuten are added to the t row (ta chi tsu te to), the t sounds become d sounds except for chi, which becomes ji, and tsu, which becomes zu.

When the dakuten are added to the h row (ha hi hu he ho), the h sounds change to b sounds.
