The first known written reference to Japan was found written and recorded in a Chinese book called the Book of Han.  It was written around the first century AD.  Do you know a lot about Japan?
I do very little about Japan.  I know I like sushi.  Can you tell me more about Japan's culture?
The culture of Japan, as far as food goes, is quite interesting.  Most of their cuisine is like many Asian cultures, it centers around rice.  But they also have miso soup and other dishes that emphasize seasonal ingredients.  I like Japanese food too.
What exactly is miso soup.  I have seen in on menus but I really never tried it.
There are varieties; but basically, it is a soup that combines a soybean seasoning, and then mix that with rice.  It is a simple soup, but it tastes great!
