Katakana is is a Japanese syllabary, one basic component of the Japanese letters, along with hiragana, and kanji. Among the syllables are the five vowels (a i u e o). The rest are syllables combined by one of these vowels with a consonant. One exception is the n [ん]. In addition, most syllables can be slightly changed by adding two small strokes or a small circle in the top right corner next to the character. For example, ha[は] changes to ba [ば] with the addition of two small strokes, or to pa [ぱ] with the addition of a small circle. This application will help you to learn Japanese Hiragana, and you enjoy learning it.
