A Video of Rice Farming Problem

I'll want to introduce a video related to rice farming problem in Japan.
I found this video on youtube.
The title is "Elderly Rice Farmers in Japan."

 Japan has a problem which most workers of rice farming are aged people. This video shows the  reasons are low rice prices, a population outflow from the country to the city and so on. Also, some youngers become rice farmers, but they say it is hard to make a living for farming. Like this, the video suggest unease about the future of rice farmers' shortage of successors and we have to consider the solution.
