Yoshikazu Kawaguchi

He is a central character in the 2015 documentary film Final Straw: Food, Earth, Happiness, one of 25 films chosen for the Global Environmental Justice Collection used in university courses on sustainability in North America. The collection won the Buchanan Prize in 2020. In 1997, his work was featured in "Natural Farming - The World of Kawaguchi Yosikazu," a documentary at the Yamagata International Documentary Festival and shown at the 2010 International Film Festival on Organic Farming in Tokyo.

In 2008 he spoke at the 17th National Gathering of Natural Farming Practitioners along with Manabu Sakai (member of House of Representatives) and representatives from the Ministry of Agriculture, Forestry and Fisheries, the Ministry of Environment and the Agricultural and Life Sciences Department of University of Tokyo.

In 1991, he started Akame Natural Farming School which currently has more than 10 sites and another 5 teaching traditional medicine and around 250 students. It is one of a number of volunteer-run "no tuition" agricultural schools in Japan. Graduates from the school have further opened 44 learning sites throughout Japan, where approximately 900 people study 'Natural Farming'. Kawaguchi is at the heart of the contemporary Natural Farmers network in Japan.

Kawaguchi was born the eldest son of a tenant farmer of many generations; unlike Fukuoka, who was from the landlord class. Kawaguchi aspired to become a painter and attended Tennoji Art Institute, whilst continuing to work at the family's farm. His father died when Kawaguchi was only 11 years old, which meant he was forced to join the family farm. However, in 1978, after 22 years of conventional farming, he experienced severe liver damage caused by the agricultural chemical fertilizers, herbicides and pesticides used on the farm. The failure of allopathic doctors to cure him led in response to Kawaguchi discovering Fukuoka's seminal book The One Straw Revolution, studying and starting to promote both Natural Farming and Traditional Chinese Medicine. He was also influenced by Wes Jackson, the founder and former president of The Land Institute; Kawaguchi is said to be the leading representative of the second generation of Natural Farming, using a gentler, more flexible approach to Fukuoka's, in which there are no definitive rules and each application depends on the individual environment.

Yoshikazu Kawaguchi (川口由一, Kawaguchi Yoshikazu) (born 1939) is the leading Japanese practitioner of the "natural farming" method popularized by Masanobu Fukuoka and has farmed by this method in Sakurai City, Nara Prefecture for 30 years. He is a farmer, author, and founder of the Akame Natural Farming School, or 赤目自然農塾 in Japanese.
