Way of thinking about marriage for young generations changed. First, the number of women who not getting married is going up in Japan. Woman do not need to financially help from man because they have more working opportunities than before. In 1965, only 2 % of population would not get married, but, now, 10% of population for woman would not get married (Bradly, Marceau, Hirata, 2018). Second, Late marriage is progressing in Japan. Young generations cannot afford to marry and provide for their family because they get low salary (fan, 2018), so they choose to stay single instead of working hard for their family. As a conclusion, marriage is no longer importance for young generations in Japan. Well-ordered living environment caused extending the average lifespan in Japan.

Decreasing the number of marriage couple and late marriage shows that the Japanese has less interested in marriage than before. Substantial medical administration and balanced diet allow to extent the average life expectancy. Values for marriage and well-ordered living environment are the key of progressing aging society.
