In 2009 when he visited rural areas during an exchange at Qingdao Agricultural University, he found that the agricultural development there relied heavily on chemical fertilizers. This experience inspired Kawasaki to find a new life goal after retirement - to develop green agriculture in China's rural areas. 

After seven years’ effort, he finally succeeded in the cultivation of organic plants, including tomatoes, and also helped a local farm to achieve relatively stable income. With his second goal of training agricultural talents, he has decided to stay in China and keep promoting circular agriculture in more places.
