Please look at this chart.

There are the number of people who are interestied in the Edo period.

Why do modern people want to know about the Edo period?

I think that the people who lived in the Edo period didn't have lots of money and things, but people could live with pleasure and smile.

Nowadays, although people have much money and food, they can't be satisfied with them.
