Japan's National Consumer Affairs Center has announced the White Paper on Consumer Affairs 2017, which shows that nearly 70% of Japanese youths age between 20 to 29 years old prefer putting their money in savings, being the highest age group preferring to do so. This is related to the trend of young people's consumption tends to become more rational, will less sense of consumption urgency. At present, the current rate of Japanese commercial banks is only 0.001%, but the Japanese people, including young people, save enthusiastically. This means that the Bank of Japan's hope for savers to spend and invest through negative interest rate might fail, and if this continues Japanese economy will have more difficulty in realizing its inflation goal.
