the '''Eto'''.

Eto originally is a Chinese calender invented in the ancient period. It consists of ten ordinal signs and twelve zodiacal symbols and the combination of both characters makes a cycle of sixty years, the '''Sexagenary cycle'''. In Japan the Eto was used not only to count time by years but also to show time by hours (In this case one day is divided into twelve fractions.) and direction. Dates based on Eto can often be seen on the '''Nakago''' of the Japanese sword.

In Kantei (Attribution), it is very important to know the Go Kinai Shichi Do as the smiths of the same region are to show the regional influence in their work. Therefore the old administrative division is still used in studying the Japanese sword.
