The final resting place

Japan with its ageing population and a lack of physical space has a problem of where to bury it's dead. 

Traditionally the population is divided up into 50% Shinto (non organised), 34% Buddhist 4% formalised Shinto and the rest a mixture, including Christians. 
A combination of pragmatism and traditional practice has made the Japanese adapt there single grave/headstone cemeteries into a mixture of high tech, low tech solutions.
The high tech end has a computerised automated retrieval system where, when you arrive to pay your respects you insert your identification card and the urn, carrying your loved ones remains are extracted from a vault and automatically presented on a Plinth with a photo of the dead person projected onto the urn. No trudging through the cemetery or tidying the plot it's all very sanitised within a modern building amongst the tower blocks and offices. Being a sceptic I wondered if the urn wasn't symbolic and the retrieval somewhat imaginary but then the whole process of dying and where you go afterwards is a bit of an illusion.
At the other end of the scale was the multiple burial plot. Here about 20 to 30 healthy people of different ages bind themselves together as a family who's purpose is to be buried in the same grave as and when the time comes. These communal plots are in ares of woodland and the selling point is not only cost but that relatives and friends coming to pay their dues have  a pleasant experience
I rather like the idea of a community born of life with a focus on death. Who knows what relationships may spring from such deliberations.
I still hanker after a cardboard coffin possibly with a happy picture on the outside. Suggestions on a postcard please.
