Bonsai
At first only the rich and noble people of Japan had bonsai. One family could have many bonsai, which would grow in pots in the garden outside of the house. A servant might take care of all the bonsai and would learn a lot about how to grow bonsai. The rules about how to grow a bonsai properly were not well known and were not shared with other people. Later more people began to grow bonsai. Some were holy people, like monks. Some were Japanese families who were not noble or really rich, but who had enough money and time to grow one or two bonsai in their gardens or house yards. This larger group of people began to share what they learned about the rules of bonsai and so more people could join in growing bonsai. By the twentieth (20th) century, the rules of bonsai were very well known in Japan and many people could afford to grow their own bonsai.
