Japanese funeral and grave are very expensive. Both cost millions of yen. There is not the memorial service of the parent now because Japanese youths are poor. Then, Japanese Buddhist temple Choukeiji started interesting service "Web Nehan(Web涅槃)". "Nehan" means Nirvana in Japanese.
Web Nehan is an online grave. Users can place the full name of the deceased, an address, photos, anniversary of a death, sound, video, motto, family precepts in the page in the Internet and can customize it freely. ID and a password are published in a user and can make a visit to a grave from anywhere if there is Internet environment. The cost is 200,000 yen in 33 years. It is cheaper than a real grave.
A point of this service is that a temple runs it. In Japan, family, grave, monk and temple are tied closely. Individual can develop similar system. However, the value of Web Nehan is to run it a temple.
By the way, the chief monk of Choukeiji is a former newspaper reporter and former TV director. He left them and became a monk. Therefore he seems to do a new challenge without being seized with old convention.
