@banana the population of japan is aging & the total population is shrinking since 2007 and will continue to do so for the next century. a drop of 1 milliion a year is expected for the next decades
One can only expect the same kind of problems for a religous group like the Jehovah's witnesses since they represent the demographics of the society. You agree with me that Japan has the largest percentage of ageing people right? Well, the same goes for the Japanese Witness group.
After 2005 things started to change and will result in an ultimate free fall
See http://en.wikipedia.org/wiki/Demographics_of_Japan#Vital_statistics
The decline in Japanese Witnesses is a normal reflection of the overall decline in the population.
For example :
Nr of Average publishers in 2009 217,530
Nr of Average publishers in 2014 215 294
Net decline 2236 publishers over a period of 5 years that is a decline of only about 0.2 percent per year
It has nothing to do with technology, being fashionable, or beliefs that answer peoples needs or not. The decline can be simply explained by looking at the demographic information of the country and the demographic behaviour in groups like the witnesses (for example within JW's less people decide to get kids because of this system/kingdom interests)
