This gradually changed as the upper and middle class started holding funerals in the mortuaries of hospitals. This posed an issue for hospitals because of the rapid increase in funerals being held and maxing occupancy. This resolved when a law was passed to allow the civilian population to hold funerals in the mortuaries of hospitals. The lower class then followed suit, copying the newly set traditions of the upper classes. With this change, the practice of cremation became viewed more as an alternative to traditional burials. Cremation was first introduced by Buddhism, but was banned in 1470. It wasn't until the Japanese colonization period that cremation was re-introduced in 1945 and later lifted the ban. It took until 1998 for cremation to rapidly grow in popularity. A Ted Talk done by Kelli Swazey discusses how Tana Toraja, a Sulawesi province in Eastern Indonesia, experiences death as a process, rather than an event. The culture of Tana Toraja views funerals as the most important event in a person's life. Because of this importance placed on death, Tana Toraja landscape is covered in the rituals and events transpired after death. The hierarchy of an individual's life is based on the sacrifices of animals made after their death. Funerals tend to be celebrated by Tana Toraja people, typically lasting days to even weeks long. Death is seen as a transformation, rather than a private loss. A Torajan is not considered 'dead' until their family members are able to collect the resources necessary to hold a funeral that expresses the status of the deceased. Until these funerals are upheld the deceased are held in Tongkonan, built to house corpses that are not considered 'dead'. The deceased can be held in Tongkonan for years, waiting for their families to collect the necessary resources to hold a funeral. The Tongkonan represents both the identity of the family and the process of birth and death. The process of birth and death is shown by having the houses that individuals are born in be the same structure as the Tongkonan, houses that individuals die in. Up until the funeral the deceased being housed in the Tongkonan are symbolically treated as members of the family, still being cared for by family members. Northern Territory Australian Aboriginals have unique traditions associated with a loved one's death.
