Shin Hanga Date Translation
Translating dates is an essential skill for shin hanga collectors. The period during which shin hanga prints flourished was a time of cultural transition, with increasing Western influence on the Japanese lifestyle. While most text was presented from right to left, some margin inscriptions read from the left, in the Occidental manner. Sometimes, compound numbers were represented in the Western base-10 number system, as opposed to the traditional method of building compound numbers. Both of these changes have since become the norm in modern Japanese written and printed text. However, the ambiguous set of rules, at the time, led to a virtual free-for-all in how dates were constructed. This websites shows how to read dates in the standard format.
