In Japan, an experiment began on August 24 to predict cabbage shipments and wholesale prices eight weeks in advance using satellite data, and to increase advertising and displays in about 50 supermarkets when supply was high. JAXA, Dentsu and JA Tsumagoi Village are running the project with cabbages grown in Tsumagoi, Gunma Prefecture.<\/p>\n

This is not an announcement that guarantees exact cabbage prices or that food waste has already been reduced. After confirming the high correlation between predicted and actual values \u200b\u200bin the 2025 data, the effect is tested in stores, and the effects on sales, farm income and food-waste reduction still need to be measured.<\/p>\n

What does the satellite see in cabbage<\/h2>\n

Optical satellites repeatedly view growth signals, such as field color and crop size, over a large area. The research team combined this data with field surveys and market data to predict harvest times, shipment volumes, and wholesale prices. For 2025 Tsumagoi cabbage, we compared the actual results with predictions made 8 weeks ago. The exact error rate was not disclosed in this announcement.<\/p>\n

What’s different in stores?<\/h2>\n

If supply is expected to increase, cabbage and related ingredients will be displayed together and cooking suggestions and advertising will be expanded. If supply appears to be decreasing, adjust the timing, scale, and messaging of promotions. Starting with the Tokyo Sangenjaya store on the first day, it will sequentially expand to about 50 stores in the metropolitan area and Kansai.<\/p>\n

Why field observation alone is not enough<\/h2>\n

Farmers’ direct inspection of their fields is accurate, but it is difficult to check large areas with the same standards. Satellites can detect supply changes early by repeatedly observing large fields. However, since there is a problem with optical images being cloudy when there are a lot of clouds, we plan to use ALOS-4 radar data, which is less affected by weather and day and night, in the future.<\/p>\n

What does it mean to consumers and farmers?<\/h2>\n

Meeting demand when supply is high has the potential for sharp price declines and less unsold produce. Consumers may see culinary suggestions more frequently during times of ample seasonal supply. However, results are not yet available on how much advertising changes demand, stabilizes farm income, or actually reduces waste.<\/p>\n

What number to check next<\/h2>\n

After the experiment, prediction errors, sales differences between stores with and without promotions, waste volume and price changes, and operating costs must be disclosed. We also need to see if the same approach works in other crops and regions. What we now know is that satellite forecasts are starting to tie into actual store operations.<\/p>\n
