Research Abstract

We collected and analyzed many archaeological datas and historical records on water-clock time systems and capital city systems in ancient palace-sites of Japan. As a result, We made clear that the origin of clepsydra and the tormation of that time systems related deeply with Ritsuriyo-systems and ancient capital city systems.
Particularly, we made definitely clear the regular time system in ancient capital city and the gates's opening and shuting time system of ancient palaces. We understood clearly that the first production of clepsydra in +660 was the big epoch of the formation of the regular time system and the gates's opening and shuting time system in ancient palaces. The centralization system of ancient nation in Japan developed on a large scale in the late of the 7th century. We understood that the first production of clepsydra and the epoch of time system was closely related with these political situation and reformation, and also the formation nf ancient capital city systems.
In ancient local public office sites, for example, Dazaifu-site and Tagajyo-site, we hare collected and analyzed many archaeological datas and historical records on water-clock time systems and city systems. In public offices of Dazaifu and Tagajyo, clepsydrans and those time systems. In public offices of Dazaifu and of 8th century. But the regular use of clepsydra in Kokuga, that is to say, provincial offices of Dewa, Mimasaka, Kaga, etc., began more slowly. We made ancient nations, and the formation of public officies and ancient cities.
About the ancient China and Korea, we collected and analyzed many archaelogical datas and historical records on water-clock time systems and city systems. We proved that techniques and systems of clepsydra, and that time systems, were adopted from those systems of Tang. But bell-and-drum time-information systems in cross roads of capital cities were not adopted to ancient Japan.
