Thanks for reading, up-voting and re-steeming.. Yes this article took some time.
I do believe the younger generation is extremely immersed in technology and are becoming more individualized to the point that many do not know how to socialize, but it is not only in Japan. I think the workaholic culture has a lot to do with it. There isn't much time for socializing and many are too tired for sex. They need to cut down the working hours so people can become more "productive".
