The certification conditions of Organic vegetables in Japan are very strict, requiring that the land where organic vegetables are grown has not been used any pesticides or fertilizers within three years. Organic vegetables in Japan sell for only 20 to 30 percent more than regular vegetables. In China, organic vegetables cost several or even 10 times as much. This shows that organic vegetable farming in China is a lucrative business.
The conclusion assumes that the price of ordinary vegetables in Japan is not too high.
