The Japanese Economic Miracle was a time in Japan's history when the country's economy grew extremely quickly between the 1950s and 1980s. It started after World War II when the country was poor and ruined, but the government and people worked very hard to help the economy improve. People started working in factories to make things, and the government invested lots of money in new technologies, like cars and electronics. They also created many factories and businesses which helped make Japan one of the most successful countries in the world. As the economy grew, people had more money to spend on things, and the quality of life also improved. It's called a miracle because it happened very quickly, and was one of the most impressive economic successes ever!
