Religion

I noticed that in asian culture, religion used to be much more active than it is today. Especially when shinto was a more prominent belief system, worship was a matter of action. For example, the kagura was designed to be performed for the gods. Failure to perform the kagura meant bad things would happen. The same for the vietnamese water puppets and its analogs in Korea, China and Japan. To not perform these rituals meant a bad harvest.With the influx of Christianity in the 1900's, these beliefs and cultures began to dilute. It makes sense though that modernity would usher in Christian religious practices.

Take the example of rice cultivation. Rice can only be grown during periods of rain and thus there is a lot of free time for people to spare. During the period between planting and harvest, people performed rituals.  With modern innovations that came from the west such as tomatoes and wheat, people began spending that time used previously for worship, to plant and thus made money. To fill the spiritual gap, people embraced Christianity.
