According to the Japanese Ritsuryo system, government of the people was based on the creation of the ancient family register system (detailed records of the people registered for each household) and yearly tax records (a register for collecting taxes of tributes and tax in kind), which were updated every year.
日本の律令制においては、人民統治の基盤として、古代の戸籍制度（世帯＝戸ごとに人民を詳細に記載登録したもの）と計帳（調・庸の税を徴収するための台帳）が作成され、毎年更新されていた。
