日本で戸籍とはいつ作られましたか？
Introduced in the 6th century, the original population census in Japan was called the or the . This census was introduced under the "ritsuryō" system of governance. During the Bakufu, there were four major forms of population registration: the (Registry of Human Categories), the (Religious Inquisition Registry) also called the "shūmon aratamechō", the (Five Household Registry) and the (Death Registry). The "shūmon jinbetsu aratamechō" was created around 1670 and lasted almost 200 years. It combined social and religious registration, and data was renewed annually. Several categories of outcasts were not registered at all under this system, or were registered in specific registers, for instance the burakumin. The modern koseki, encompassing all of Japan's citizenry, appeared in 1872, immediately following the Meiji Restoration. This was the first time in history that all Japanese people were required to have family names as well as given names. Although all previous social categories were abolished and almost all Japanese people were recorded as "heimin" (commoners), some minorities became labelled as "new commoner" or "original eta" ("shinheimin" or "motoeta"), and discrimination went on. Problems also happened at the edge of the national territory, for instance in the Ogasawara Islands.
