What script is the origin of Japanese writing?

The Japanese writing system consists of several scripts. In the Japanese writing system, Kanji, Kana, and Romaji are used functionally equally as cursive scripts.

Kanji (Japanese: 漢字) originate from Chinese script (Chinese: 漢字 / 汉字, Hànzì) and, as logograms, usually represent the root of a word.

Kana, i.e., Hiragana (Japanese: 平仮名 or ひらがな) and Katakana (Japanese: 片仮名 or カタカナ), are syllabic scripts (more precisely, moraic scripts) from the historical Man'yōgana system, which is derived from the Chinese "grass script" (also called draft script).

Kanji (Japanese: 漢字) are derived from Chinese scripts. Modern Japanese uses the Latin alphabet as its writing system, known in Japan as Rōmaji (ローマ字).

Numbers are written using kanji or Arabic numerals.
