Abstract
Daikon radish, a key root vegetable in Japan, has seen significant fluctuations in harvest yields, cultivated area, and shipping volumes over the years. In 2022, the national harvest reached a peak of 1.18 million tons, reflecting improvements in farming techniques and favorable conditions. The cultivated area stood at a maximum of 28.1 thousand hectares, with Chiba leading the nation in shipping volume at 135,000 tons. Historically, regions like Chiba have dominated shipping, while nationwide yields have varied with weather and market demand. These trends highlight the importance of both climate factors and regional expertise in daikon production.
Daikon radish harvest yield (main data).
Daikon radish production in Japan has seen notable fluctuations since 1973. The peak harvest reached 2.76 million tons in 1977, but by 2022, nationwide yields had dropped to just 42.8% of that record. Several factors contributed to this decline, including changes in consumer preferences, urbanization, and reduced cultivation areas. Despite this, regions like Chiba remain strong producers, maintaining steady shipping volumes. Modern agricultural techniques and regional expertise continue to play a key role in sustaining daikon production, even as overall yields have diminished compared to the peak years.
The maximum is 2.76Mt[1977] of Japan, and the current value is about 42.8%
Daikon harvest volume (by prefecture).
In 2022, Chiba Prefecture led Japan in root vegetable production with a record-high yield of 145,000 tons, maintaining its position as the top producer. This trend highlights the region’s expertise and favorable growing conditions for root crops like daikon radish. Over the years, Chiba has consistently dominated production volumes, benefiting from advanced farming practices and optimal soil quality. While other regions also contribute to Japan’s root vegetable supply, Chiba’s output remains the benchmark, reflecting both regional specialization and the importance of local agricultural practices in sustaining high yields.
The maximum is 145kt of Chiba, the average is 25.1kt, and the total is 1.18Mt
Area cultivated with daikon radish (main data).
Daikon radish cultivation in Japan has experienced a significant decline since its peak in 1973, when the nationwide cultivation area reached 76,000 hectares. By 2022, this area had shrunk to just 37% of that peak, reflecting changes in farming practices, reduced demand, and urbanization. As agricultural land use shifts towards more profitable crops, daikon radish cultivation has been concentrated in select regions like Chiba. Despite this decline, specialized areas continue to maintain yields, adapting through improved farming methods to meet local and national demand.
The maximum is 76kha[1973] of Japan, and the current value is about 37%
Daikon radish cultivation area (by prefecture).
In 2022, Hokkaido led Japan in the area allocated for root vegetable cultivation, with 2.78 thousand hectares, reflecting its significant role in the nation’s agricultural landscape. This trend highlights Hokkaido’s favorable climate and vast farmland, making it ideal for large-scale root vegetable production. Over the years, the region has maintained its dominance due to its extensive farming infrastructure and expertise. While other regions also contribute to root vegetable production, Hokkaido remains a key player, continually adapting to meet changing agricultural demands and ensuring a stable supply of root crops.
The maximum is 2.78kha of Hokkaido, the average is 599ha, and the total is 28.1kha
Daikon shipping volume.
In 2022, Chiba Prefecture led Japan in daikon radish shipping volume, with a record-high of 135,000 tons, accounting for a significant portion of the nation’s total. The average shipping volume across Japan was 21,000 tons per prefecture, contributing to a national total of 987,000 tons. Chiba’s dominance in shipping reflects its efficient production and strong infrastructure. While other regions also contribute to national supply, Chiba’s advanced farming techniques and optimal conditions allow it to consistently maintain the highest shipping volumes, highlighting its crucial role in Japan’s root vegetable industry.
The maximum is 135kt of Chiba, the average is 21kt, and the total is 987kt
