Japanese uses a combination of the following three writing systems:
Kanji: Chinese characters, introduced to Japan via Korea around the third or fourth century AD, are primarily used for word roots and stems. There may be as many as 50,000 kanji characters, though only 5,000 to 10,000 are commonly used.
Hiragana: 46 phonetic symbols, curvilinear in style, used mainly for grammatical elements of Japanese such as verb and adjective endings and particles.
Katakana: 46 phonetic symbols, more angular in style, used to write words imported into Japanese from other languages  and foreign names.

Kanji and kana (hiragana and katakana) characters are written according to established principles of stroke order with "top to bottom" and "left to right" being the most important.  A knowledge of these principles is extremely important to achieve the proper shape of the characters.

The beauty of kanji has been expressed for centuries in calligraphy, the art of drawing characters with a brush. Nowadays, with the aid of computers and modern printing technology, it is possible to print perfectly formed kanji and kana characters in a variety of colours and styles on T-shirts and other apparel.
