Japan’s cucumber, tomato and eggplant prices rise as difficult weather restricts supply
Wholesale prices for major summer vegetables in Tokyo rose sharply as cloudy June weather delayed growth and subsequent heat disrupted harvesting and marketable yields. Cucumbers were 28% more expensive year on year in mid-July and more than 30% above the normal level in the latest market data.
Tokyo wholesale prices climb
Wholesale prices for Japan’s main summer vegetables have risen sharply after a cloudy June delayed crop development and a subsequent spell of intense heat complicated harvesting and reduced marketable supply. The disruption is affecting cucumbers, tomatoes, eggplants and green peppers, important seasonal ingredients for households and restaurants.
In mid-July, cucumbers at the Tokyo Metropolitan Central Wholesale Market averaged ¥456 per kilogram, 28% above the same period a year earlier, according to Nikkei. Eggplants were 27% higher at ¥526 per kilogram, while tomatoes rose 22% to ¥504 per kilogram. More recent market data cited by tenki.jp showed cucumbers trading more than 30% above the normal level, with eggplants, tomatoes and green peppers also recording broad price increases.
Cloudy weather gives way to damaging heat
The supply squeeze reflects two different weather problems in quick succession. A lack of sunshine during cloudy conditions in June slowed plant growth. After the rainy season, stronger sunlight and rapidly rising temperatures changed field conditions again, making the direction of prices difficult to predict.
Heat has not simply reduced growth. At Tokyo Chikyu Farm, cucumbers absorbed water stored in the soil during the rainy period and then expanded rapidly when temperatures surged. Farmer Takeo Kubota told tenki.jp that growers could not keep pace with harvesting and had to discard around 30% because oversized cucumbers could no longer be sold through the market.
That combination creates an unusual supply problem: crops may grow quickly, but a significant portion can miss commercial size and quality standards before farmers can harvest and ship it. Dangerous heat is also raising concerns in Kumenan, the largest cucumber-producing area in Okayama Prefecture, where growers fear that both quality and harvest volumes could decline during the peak collection period.
Restaurants face another cost increase
The higher prices are reaching food-service businesses during strong seasonal demand. At Chugoku Teuchi Ramen Bazoku, a hand-pulled noodle restaurant near Nippori Station in Tokyo, customers continued to queue for chilled noodles while central Tokyo recorded five consecutive extremely hot days. Cucumbers and other summer vegetables are essential ingredients for the restaurant’s chilled dishes.
The restaurant raised prices by ¥200 in 2025 in response to higher ingredient costs. Manager Mitsutaka Mori told tenki.jp that the business would like to raise prices again but was trying to hold the line as customers continued arriving in the heat. Its experience illustrates the pressure on restaurants that must choose between protecting margins and limiting further increases for consumers.
Price outlook remains weather-dependent
The next move in vegetable prices will depend on whether stronger sunshine improves yields or continued heat causes further crop damage, quality losses and harvesting problems. Faster growth can briefly increase field availability, but it can also generate more waste when labor cannot keep up or produce becomes oversized.
For growers, the immediate challenge is converting rapidly maturing crops into marketable shipments. Wholesalers and restaurant buyers face uncertain volumes and potentially volatile procurement costs. With several major summer vegetables affected at the same time, relief for buyers will require not only better growth but also stable quality and a harvest pace that farms can manage.
