While struggling with accepting the death of her only son,she learned about service of the funeral home that can restore a deceased person as a humanoid for only 49 days.

In the film, the idea of the "49 days" (shijūku-nichi) is presented. This idea has a special significance for Japanese people.
It refers to the Buddhist service where, following the funeral, the
ashes of the deceased will be kept for 49 days at home instead of
immediately being put away in the tomb.
In Japan, the spirit of the deceased is believed to remain in this world
during those 49 days. The period is meant for the spirit to find peace
with itself, while the remaining family members remember the deceased as
they live alongside them.
I also feel that the period of 49 days is meant for those that have been left behind to come to terms with the fact of their having lost a loved one. Once the ashes have been placed in the tomb, the deceased no longer exists in this world.
Given such beliefs and rituals in Japan, I believe such service as the one depicted in this film may appear one day.
