(Today’s blog is all about Japan’s history)
Suddenly, was the establishment date of the Kamakura Shogunate was 1192? (This questions is very common for people who have educated at Japanese school)

Right! Those who think that you know the age. I heard that the theory that it was established in 1185 recently. The school textbook also said that it is 1185 years.

However, 1185 years seems to be doubtful, and there are other theories in 1180, 1183, 1184 and 1190 in addition. What do you call “Kamakura shogunate”? According to its interpretation the age is different.
