Japanese mums work too much - After reading of JAPAN

Japanese working mum is very busy every day, especially mum with kindergarten or elementary school age children is. Japanese women desire to share of child rearing and housework with their husband. But, their husbands do not go back home early and Japanese women need to all tasks by herself.
Japanese men are not fully aware that they should do all the child rearing and housework.
I personally think that it was caused that old Japanese family divided wife/husband or mother/father’s responsibility. Thus, a lot of older people and their son may become dependent on young mums. And young mums may think that mums should do everything right/perfectly as her mother did though young mums work.
Now Japan government proceeds with the Realization of Work Style Reform. I already realized my work style reform and changed my mind to taking care of my nephew and usually leave at the fixing time after finish my tasks. I strongly suggest all workers to prioritize and control the tasks efficiently before ever with aim of leaving at the fixed time and to take paid holiday more. The people can enjoy hobby and relax, and can do the child rearing and housework after the hours and during paid holiday. Please give Japanese mums rest more.
