Japanese is written using three alphabets: hiragana(ひらがな), katakana(カタカナ) and kanji(漢字).
Hiragana and Katakana were created in Japan. Each of them represents sounds only.
The kanji are different. Each of kanjis has meanings and several pronunciations.
Ex: 人 means people, person.
You can choose your favorite Kanji, hiragana or katakana to create your original hanko.
