In truth, I intend to be cremated by the Neptune Society, but my ashes should go to Japan and Israel. Specifically to the most crowded part of Shinjuku in Tokyo and the beaches of Tel Aviv.
When I looked up the issue of burial or ashes in Israel I found that there is a significant industry in that field. Many Jews want to be buried where their ancestors lived and were buried. Maintaining a 3000 year old tradition.
I will be cremated so all the costs of shipping a body are irrelevant. I actually have friends and clients in Israel so making business arrangements is equally irrelevant.
However, there must be a vast number of Christians for whom scattering ashes in the holy land would be appealing. I see no business oriented in that direction.
It shouldn't be difficult to set up such business. It would consist mostly of listings in relevant Christian pro-Israel media.
I have a long history of having started businesses, nearly all of which have failed. This idea is free to anyone.
