🥬 Sept 2026 Vegetable Price Outlook

❓ What was announced?

On August 28, 2026, Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) published its growth and price outlook for vegetables shipped to the Tokyo Metropolitan Central Wholesale Market in September 2026. Because unstable weather has been driving larger price swings, MAFF has issued this monthly outlook since 2011, based on interviews with major production areas and wholesale companies, to help growers time shipments and help shoppers plan purchases. For September, cucumbers and tomatoes are expected to trade above the average. Cucumbers from the Tohoku region saw growth stall due to a lack of sunshine and cool mornings and evenings from late July through August; tomatoes were hit by low temperatures in June and limited sunshine, with concerns over poor fruit set caused by a sudden heat spike in mid-July. Both are forecast to run slightly above average in the first half of September and return to normal in the second half. By contrast, potatoes and onions — 97% and 90% sourced from Hokkaido respectively — are growing well and running large, so shipment volumes should exceed the average and prices fall below it. Lettuce also comes in below average as Nagano shipments recover. Carrots are below average only in the first half of the month, while daikon, Chinese cabbage, cabbage, spinach, green onions, broccoli, eggplant, green peppers and taro all stay at normal levels. "Average" here means the average of the past five years, and a ratio of roughly 90–110% is labeled "normal." Note that under the 2025-base Consumer Price Index, the food index for July 2026 stood at 103.1 and is trending up, so "below average" does not automatically mean cheaper than last year.

👥 Who does this affect?

• ●Foreign residents who cook for themselves — students, single workers — and want to keep food costs down
• ●Households in Japan buying groceries for a family
• ●Foreign nationals running or working at restaurants, delis or bento shops that use a lot of vegetables
• ●People on vegetable-centered diets, including vegetarian and halal
• ●Anyone who plans meals and shopping around supermarket sales

🌏 Impact on foreign residents

With food prices climbing, knowing in advance which vegetables are expensive and which are cheap is especially useful for foreign residents who are not yet comfortable reading Japanese product labels. Cucumbers and tomatoes run high in early September, so switching salads toward lettuce and onions, or cooking with eggplant, green peppers and cabbage — all at normal prices — can cut your grocery bill with a simple menu change. Potatoes and onions should be plentiful and cheaper, and since both keep well at room temperature, they suit bulk buying and batch cooking. The "Hokkaido" and "Nagano" origin labels you see in supermarkets also start to make sense alongside this outlook. When 90% of onions and 97% of potatoes and carrots come from Hokkaido, weather in that one region flows straight through to the price tag. Keep in mind, though, that these are wholesale price forecasts for the Tokyo Metropolitan Central Wholesale Market, not retail shelf prices; rural areas and small shops can move differently. If you run a restaurant, use it as a reference when planning early-September purchasing.
