Japan is a developed country. One reason why is the literacy rate is 99%. Literacy rate,how many people know how to read and write. Reading and writing are very important, most jobs require that or else you can't work there. Another reason is that the life expectancy is 84.46 years this is the average life spand for men and woman. Living a long life would be most people's dream. Also living a long life he or she could be a grandma or grandpa or dad or mother. They could tell there relatives about there great life hopefully. My last reason is the GDP per capita is 37,100. GDP mean total value goods and services per year. 37,100 is a good number and shows that they can pay for school and medicine and etc. Japan is a developed country.
