Ecoplus conducted a weekend farming workshop, ‘ABC of Rice Farming: Weeding’, in Minamiuonuma City, Niigata Prefecture, on the weekend of 20–21 June 2026. Thirteen participants, including four families with children, joined the event from the Tokyo metropolitan area and the local region. They took on the challenge of ‘weeding rice paddies’ — the greatest hurdle in pesticide-free rice farming — and observed the maintenance of terraced rice fields in a mountain village, gaining first-hand experience of the realities of rice cultivation.
The dry weather had persisted since May and the mountain streams had run low. However, this weekend, the rainy season front moved northwards, bringing rain. Consequently, we brought forward our work in the rice paddies to Saturday the 20th.
Weeds such as ‘konagi’, which has long, narrow leaves that spread out in a cross shape, and ‘omodaka’, which has pointed, triangular leaves, are growing in the rice paddies. ‘Inubie’, which resembles rice plants when standing upright, is also sprouting up here and there. Some inubie are even growing out from the roots of rice seedlings that have grown to around 30 centimetres tall, as if hiding among them.
After the rice was planted in mid-May, we held three weeding sessions with the help of a fieldwork team from Waseda University, among others. Nevertheless, weeds are sprouting up again. Moreover, in areas where the soil was exposed due to a lack of water, we had to pull the weeds out by hand, which was very labour-intensive.
Thanks to the guidance of local veteran KATO Yoshiharu and the participants’ hard work, we managed to clean two sections of rice paddy totalling around 500 square metres in just two and a half hours. The entire paddy now looks much tidier.
On the second day, it was drizzling. We visited the terraced rice fields in Tochikubo village, which is located about 300 metres higher up. HIGUMA Keiichi, a young full-time farmer, was mowing the weeds along the ridges. Pampas grass and other weeds, growing nearly chest-high, covered the wide, steep ridges densely.
“In terraced rice paddies, the area of the ridges is greater than that of the paddies. Managing the ridges and the irrigation channels that run between them is crucial,” explained Mr HIGUMA, who was drenched in sweat and rain. He also showed us the structure where the main waterway is dammed in places to divert water into the paddies on either side.
Our guide, wildlife expert FUKAZAWA Kazuki, discovered the eggs of a forest tree frog beside a disused rice paddy. The participants were surprised to see the white, foam-like eggs, which were about 10 centimetres in diameter, on a branch about 4 metres high.
They commented, “I was surprised to hear that it takes a month just to mow the grass along the ridges of 90 rice paddies once, and that we’d be doing that three times.” They also shared positive feedback such as, “The feel of the soil and the scenery while weeding are wonderful,” “This is a volunteer activity, so I’ll come back to weed again within the next two weeks,” and “It would be great if we could grow herbs in the fallow fields.”
From 30 to 31 May 2026, Ecoplus hosted and supported 23 Waseda University students during a field study in Kabanozawa village, Minamiuonuma City, Niigata Prefecture. This was part of the “Field Basic Seminar”, led by Professor Takako Takano, who also serves as Ecoplus’s executive director. Twenty-three second- and third-year students participated.
We stayed in the Kanazawa village, which is home to the Joetsu Kokusai Ski Resort’s guesthouse district. On the first day, we headed to the chemical-free rice paddy used by Ecoplus for its “ABC in a rice paddy” programme. Rice planting had been completed there just a week earlier. We tried our hand at ‘additional replanting’ — the process of replanting seedlings that had been washed away because they had been planted too shallowly during the initial planting.
As soon as the students stepped into the paddy barefoot, there were screams of “Eek!” and cries of “There’s something on the bottom of my foot!” Once things had settled down, we took a closer look at the paddy and noticed the abundance of creatures unique to pesticide-free farming. We gently straightened seedlings that were about to fall over, adding two or three more to spots where there was only one. We worked our way through the field, doing this.
Working together as a team of 23, we replanted an area of about 300 square meters in just 30 minutes. Next, we moved to a field about half that size to pull up newly sprouted weeds. Despite it being only a week since planting, the fine weather had enabled the weeds to extend their slender leaves a few centimetres above the muddy surface. We loosened the roots by stirring the mud with both hands. Since the weeds wither once exposed, there was no need to pull them out.
This task was performed in rice paddies all over Japan until around 50 years ago. While it was undoubtedly familiar to the Japanese people of that era, many of whom were farmers, it was a new experience for the young students.
Next, we heard firsthand accounts of the current realities facing rice farming from local elder TOGE Hideo, veteran farmer KATO Yoshiharu and young full-time farmer HIGUMA Keiichi.
On the second day, we visited a temple that has long been a pillar of the community. We then attended a talk by OGAWA Yasuhiko, the head priest of Ryuzan-ji Temple, which dates back over 600 years. The students asked Mr Ogawa questions about his training days and the challenges facing the community. Mr Ogawa shared, “I am still training every day; this very place is my training ground. My wish is for the people of this community to live better lives. Rather than telling them what to do, I listen to them and support them — like a strap on a train when it sways.”
During the walking tour, participants explored the local area alone or in groups, talking to passersby and observing the environment. This gave them hands-on experience with the basics of fieldwork.
During the reflection session, participants shared comments such as “I realized just how tough the current situation is for farmers,” “I’d only ever been on the consumer side, but now I understand the producers’ perspective,” and “I was moved by the beauty of the natural scenery.”
若い世代にとっては、体験を通じて視野を大きく広げる機会になったようです。
For the younger generation, this experience seemed to be a valuable opportunity to broaden their horizons significantly.
On April 25 and 26, 2026, ECOPLUSP hosted the “Enjoying the Ooyamazakura” event in the Shimizu village of Minamiuonuma City, Niigata Prefecture. Eight participants with business persons, journalists, historian, and university students from the Tokyo metropolitan area and elsewhere, visited the Ooyamazakura tree, famous for blooming atop the snow.
This year, the snow melted quite early. Even at an elevation of around 800 meters, where there is usually about 50 centimeters or more of snow remaining, there was almost no snow. The shrubs, which are normally held down by the snow, had sprung up and formed bushes. Because of this, we had to push our way through the brush, a process known as “yabukogi.”
After about 30 minutes, we reached the Ooyamazakura, which had already passed its peak bloom, with petals fluttering gently to the ground. The characteristic red young leaves of the Ooyamazakura were beginning to emerge, creating a stunning contrast with the snow at the 2,000-meter-high ridge and the fresh greenery of beech trees and other plants.
Dinner at the guesthouse “Yamago,” where we stayed, was a feast of local mountain vegetables. The menu included young shoots of Mitsuba Akebi—the most prized local delicacy—refreshing, mild-tasting fiddlehead ferns, high-quality bracken (dried from last year’s harvest), and assorted tempra of “Taranome,” “Koshiabura,” both are young buds of trees, and buds of butterbur . We thoroughly enjoyed this meal paired with local sake.
The second day was also sunny and clear. We entered the beech forest behind the village. This forest has been protected—with a strict prohibition on cutting down trees—to prevent avalanches from reaching the village. Beech trees over 20 meters tall stand in rows, including giant specimens estimated to be 200 years old. The young leaves covered the entire sky, creating a space enveloped in fresh green. The chirping of small birds echoed through the air.
In the middle of Mt. Makihata (elevation 1,967 m), one of the wild cherry trees, the O-yama-zakura, blooms silently amid the snow. In late spring, we will visit the site and enjoy the cherry blossoms over the snow.
Whether or not the cherry trees will be in full bloom depends entirely on the progress of the season. Either way, we will enjoy the sudden appearance of flowers and young leaves during the late arrival of spring in the deep mountains. We will conduct the program under the security advice of the local hunters, expecting the bears to wake up early from hibernation. Due to the age of the family that operates the inn, we can only accept a limited number of applicants.
Contents: Hiking over the snow, Nature observation, Visiting cherry trees. Hiking in the beech forest, Enjoying the local dishes, and so on. Break up will be 10 am on site, then you can come down to the town where you can stroll the street, called, “Bokushi-Dori,” which represent Edo time atmosphere, or other museums.
Fees, 6,000 JPY for the program including guides, equipments, insurance and others, which is 3,000 JPY for students and children. Lodging fees around 8,000 JPY needed.
Transportation: Public bus service will be terminated at the end of March. If you are not coming by car, you need to take taxi from JR Shiozawa Station, or sharing ride with staff or other participant coming by cars.

We enjoyed the rice harvesting workshop of “The ABCs in Rice Paddies” with 15 participants on September 20-21, 2025, in the Kabanozawa village of Minamiuonuma City. Due to the unstable weather, we changed our plans and harvested rice on the 20th. On the 21st, amidst pouring rain, we observed a local farmer’s “rice preparation” work and learned about the current state of rice farming.
With only 35 millimeters of rainfall in July, less than 20% of the average, the rice paddies in Minamiuonuma were left cracked and in terrible condition. Rain finally came in early August, providing some relief, but temperatures remained over two degrees higher than average throughout the summer. The two pesticide-free paddies that we tended to through planting and weeding, following the basics of rice farming, have shorter stalks and fewer stems than last year.
On the 20th, rain was forecast for the evening, so we quickly finished lunch and headed to the fields to start harvesting. We began cutting the rice with sickles. The tricky part was bundling the cut rice. After listening to explanations from veterans who had participated several times before, we each struggled but managed to finish making rice bundles.
Occasionally, sunlight filters through the blue sky. A strong wind blows from the south, causing the rice stalks to sway like waves. During breaks, we were soothed by the sounds of insects like crickets while gazing at the rice fields stretching out before us.
Work progressed smoothly, and the first field was finished in about two hours. “We still have time, let’s do it,” said one participant. We started harvesting the second field. Everyone was getting the hang of it, and roles naturally divided: some cut, some bundled, some carried, and some hung the bundles on the drying racks. In just one hour, we neatly harvested half the field.
Heavy rain fell on the second day, starting in the early morning. We split up and rode in cars to visit the Tochikubo village, which was located about 300 meters higher in elevation. During a break in the rain, we toured the rice paddies and explored the beech forest.
At local farmer HIGUMA Keiichi’s workshop, the “adjustment” process was underway: removing moisture from the harvested rice, dehusking it, removing stones and other foreign objects, and sorting out small or discolored grains. “This year’s rice is beautiful,” he said, showing us the finished product.
Japan Agriculture’s purchase price for rice has risen from ¥20,000 last year to ¥33,000 this year in Minamiuonuma. Furthermore, an additional ¥4,000 seems to have been added in September. During the discussion session after the tour, veteran local farmer Kato Yoshiharu explained the current situation, stating: “The latest combine harvesters can cost as much as 25 million yen. Considering the price of machinery, farms of the previous scale simply can’t survive.”
In recent years, particularly, unstable weather patterns, including abnormal heat, droughts, and prolonged rains, have persisted, leading to ongoing instability in the quality and quantity of rice. Even if we aim to increase production, expanding the rice fields isn’t something we can easily do.
Mr. HIGUMA lamented, “I heard the minister came to Minamiuonuma City to inspect the drought situation, so I called city hall. They said no special budget measures were allocated. He just came to look.” Hearing this, the participants also felt the severity of the rice problem.
During a visit to a local supermarket, locally grown new-crop brown rice was being sold for 10,000 yen per 10kg bag. “At this price locally, it’s no wonder they charge 7,000 yen for 5kg in the Tokyo,” someone remarked.
