Aoyama Shop, where he first encountered organic vegetables. In 1998, Takahashi joined natural food products retailer Natural House Co., Ltd., where he helped complete a transition from additive-free foods to organic food operations, managed their retail shops, planned sales promotions, and worked with produce buyers via the products division. Following the 2011 Tohoku earthquake and tsunami disaster, he went independent and founded warmerwarmer. Working in cooperation with organic farmers all over Japan and organizations with ties to organic farming, he has endeavored to popularize vegetables with roots going back to ancient times and develop new agricultural markets for the future.

Hanjo joined the farming profession in 2016 in Ome City, Tokyo. Within the generally urban prefecture of Tokyo-to, he located this lush natural environment in which to pursue his environmentally friendly agricultural operations. In addition to 100 different standard-type vegetables grown throughout the year, Hanjo Farm also produces Western vegetable varieties as well as traditional vegetables of Tokyo and its predecessor city Edo. In Ome, a city known as the gateway to both the Tokyo metropolis and the forests outside of it, Hanjo pursues education on agriculture and food in order to promote agriculture among the residents of the big city. Operating on the motto "Connecting People With Agriculture," Hanjo and his farm will continue to pursue new challenges in agriculture.

Misaki Farm harnesses the power of Mother Nature to grow organic produce without relying on chemical pesticides, chemical fertilizers and the like. Their motto, "From the Soil to Your Mouth," shows their dedication to the entire process of making delicious vegetables, from preparation of the soil through to the customer's first bite. The farm grows about 60 different types of produce in pursuit of low-volume, high-variation production that delivers the unique flavors of all four seasons. In addition to the farm, Misaki runs Sachi Cafe together with her mother, where they use self-grown vegetables in dishes served to customers. The farm’s name is written as ‘Misaki Farm’, where ‘mi’ signifies sincerity and prosperity, and ‘saki’ conveys the idea of smiles and flowers blooming. They work in their fields every day with heartfelt dedication, hoping that the vegetables they grow will naturally bring smiles to the people who eat them.

This agricultural high school has a long history and long-established traditions—they celebrated their 130th anniversary in 2023. It provides education via five academic departments: Bioengineering, Production and Distribution, Food Engineering, Environmental Engineering, and Lifestyle Culture. Over the years, the school has produced numerous graduates who went on to become farmers and agricultural leaders throughout Miyazaki Prefecture and beyond. With the goal of training human resources capable of serving effectively in today's industrial society, they embarked on endeavors during the 2024 and 2025 academic years to spread awareness of and promote the "Meister High School" program. In practice, this involves collaborative learning with industry partners and cross-departmental, interdisciplinary study. In addition, the school has received high praise for its educational focus on the MIDORI Strategy for Sustainable Food Systems integrating technologies and techniques that reduce environmental loads. Specifically, these include small-plot cultivation using processed materials made with shochu liquor lees and spent grain from beer brewing (which were previously unutilized resources), composting of biodegradable clothing products, reduced-pesticide cultivation to handle common crop pests, and other such approaches aimed at realizing people- and environment-friendly farming methods. The school integrates these approaches into student projects as part of the curriculum. With an eye on the continually evolving agricultural industry, the school not only provides students with specialized knowledge and skills in each department, but also works to cultivate individuals who can approach agriculture and daily life with broader perspectives.

Born in Tokyo in 1944, Otake graduated from the Tokyo University of Agriculture (Laboratory of Tropical Horticultural Science) and, from 1989 onward, pursued the revival of Edo Tokyo Vegetable for JA Tokyochuo. In 1997, he planned and installed 50 informational signs throughout Tokyo explaining the agriculture of Tokyo and its predecessor city Edo, and has pursued a number of other promotional efforts as well. Otake has been named by the Minister of Agriculture, Forestry and Fisheries as an "Expert on Local Production for Local Consumption" as well as a "Voluntary Planner" in that same capacity. He also serves as a "Regional Empowerment Advisor" for the Ministry of Internal Affairs and Communications. As representative director and chairperson for the NPO Edo Tokyo Vegetable Concierge Association, Otake works to spread awareness of and popularize traditional Edo Tokyo Vegetable, and he also serves as a member of various other committees and as a lecturer.

Tenchijin, Inc. is a Japan Aerospace Exploration Agency (JAXA) certified startup that utilizes satellite data and AI technology to assess and analyze land, environment and infrastructure conditions. As the first space-industry startup in Japan to receive JAXA funding, Tenchijin utilizes data from earth observation satellites (meteorological data, Geographical data, etc.) in solutions for a wide range of societal problems. Tenchijin COMPASS, our main service, provides analyses based on both satellite and ground data in support of decision-making processes in many different fields, including agriculture, renewable energy and waterworks infrastructure. By providing objective data in easy-to-use, visual form for workplaces in such fields, Tenchijin COMPASS helps people make informed decisions and take action more effectively. The company's mission is to "Optimize human activity through the power of space data." As climate change continues to intensify, creating more problems every year in agricultural environments, there are times when farming experience alone isn't enough to see all factors involved. Tenchijin analyzes land suitability for cultivation by combining satellite data with meteorological data. In this project, Tenchijin will apply this expertise to explore ways to optimize growing conditions for endangered vegetables. By visualizing current farmland conditions, we aim to support decision-making that helps pass local vegetables on to future generations.
