Behind of my clinic is rice paddy field.
The rice seedlings are done by automatic transplanter machine, which
introduced in 1970'~80' in Japan.
The rice harvesting machine also relief the manual works. But, the rice
production in Japan is inefficient, since the average land area of one farmer
own less than 1.0 hectare. After WWII, US occupation forces performed
the radical land reform in Japan. As a result, the large land owner had
disappeared and spitted the land into small piece one.
