Chinese Horoskop vs. Japanese Horoskop

[Kaigen]

I was wondering about Chinese Horoskop.
as we know it starts in (example) Feb 17 1969–Feb 05 1970 Yin Earth 己 酉 Rooster
So I'm Rooster, people born in January 1970 should be rooster too.

That's where my problem starts. As you know I live in Japan, so why is the Japanese calendar different in dates?
even in Germany the Chinese horoskop have the same dates and is not called German calender.

Wiki: _https://en.wikipedia.org/wiki/Chinese_zodiac

The Japanese zodiac includes the Sheep instead of the Goat, and the Wild Boar instead of the Pig. The Japanese have since 1873 celebrated the beginning of the new year on 1 January as per the Gregorian Calendar.

That means, they adapted Chinese horoskop with Gregorian calendar? :O

It looks like that's what has happened. As you may know, the modernization efforts that were initiated in the Meiji period were quite extensive, and in order to become "as modern as the West", altering what originally was a lunar calendar system with far more deviations than the Gregorian calendar kind of makes sense, I guess.
