Today is a national holiday, Kenkoku Kinen no Hi or National Foundation Day. This day was originally called Kigensetsu or Emperor Day came from Nihonshoki. The ancient report said that the first Emperor Jinmu established Japan on this day.
Japan is one of the oldest countries in the world. Japanese ancient calendar says it's 2676th year now. Of course that is unreliable theory, but still Japan has its long long history. I'm really proud of that.
Today is Japan's National Foundation Day. It is based on Japan's old history book Nihonshoki. It says the first Emperor Jinmu Tenno acceded to the throne on the date.
National Foundation Day holiday was once suspended after WW2, but came back to a national holiday in 1967.
Normally, Japanese people don't do anything special for the day, but some people display the national flag in front of their porch. I think it is a good day for thinking of our nation today.
