This has more to do with non conventional home funerals...
Thanks for your reply, but this has more to do with what is needed to be done according to the laws of the society (State Law) by the society in which one lives.
I posted the movie first to show the cultural difference in which this is done in Japan. Home funerals are a rarity in the West. Home funerals were a thing of the past, here in America. Homes use to be built with attached parlors, but the home parlors became somewhat obsolete & later these rooms came to be called 'living rooms' when funeral parlors came into existence when the matter of funerals became something that a business does instead of something a family does in their own home. There are some things to consider if one wants to go this way. Such as dry ice can be used to keep the body preserved for a few days instead of embalming (which involves toxic chemicals) for the purposes of viewing the body in a home environment. Some preparation can be done by the one who is going to die, and/or by the family members.
One can make it a meditation by considering one's own death, by laying out the steps for a family member to follow, prior to one's own death. This is so family members don't have to scramble around trying to do things haphazardly in a hurry-up mode.
