Old Japanese Clock

By Takafumi AMANO

This app is only available on the App Store for iOS devices.


This app is a time converter between current hour system and old Japanese hour systems. It can use two systems, fixed hour system and temporal hour system. The fixed hour system has six system types, engishiki, guchureki, semmyoreki, semi-engishiki, kanagoyomi and shichiyoreki. There were used mainly from the Nara era through to the Edo era (710-1872) . The temporal hour system has seven system types, temporeki, koten, shaku-sun-bu (class 1 and 2), three-divided (class 1 to 3). There were used mainly in the late Edo era (1844-1872).

The app is useful when you will read a Japanese historical document, adjust a Japanese clock, mimic samurai life, and so on. If you need more information, please check developer's web site.
