Abstract
The latest data on rapeseed harvest volume, planted area, and yield per 10a in Japanese agriculture is based on 2022. Nationally, rapeseed yield was 3.68kt and area planted was 1.74kha. Hokkaido recorded the highest yield per 10a at 307kg. The trend that can be inferred from these figures shows that although rapeseed production is still not very large nationwide, relatively high yields are being achieved. Hokkaido’s high yields can be attributed to local characteristics such as climatic conditions and soil adaptability. In rapeseed production, it is important to continue to promote efficient production techniques and sustainable agriculture. In addition, there is a need to formulate more effective production plans and policies that take into account regional differences in productivity.
Rapeseed yield (main data).
Rapeseed harvests in Japan have fluctuated between 1958 and 2022. The highest recorded rate was 274kt in 1961, and although it has fluctuated since then, it has now settled at a peak of 1.35%. This trend shows that Japan’s rapeseed harvest has been declining since its peak. This is thought to be due to a variety of factors, including structural changes in agriculture, technological innovation, and economic changes. In addition, the rate of decline has been relatively gradual, which is presumably due to the stability of demand for rapeseed production and the efforts of producers. In the future, efficient production methods and strategies that can respond to changes in demand will be required.
The maximum is 274kt[1961] of Japan, and the current value is about 1.35%
Rapeseed harvest volume (by prefecture).
According to the latest prefecture-by-prefecture data for 2022 regarding rapeseed harvest volumes in Japanese agriculture, Hokkaido recorded the highest yield overall at 3.07kt. This is the highest value compared to past data, indicating that Hokkaido is a major rapeseed production region. Hokkaido, with its vast farmland and status as a grain-producing region, offers an ideal environment for cultivating rapeseed. Meanwhile, production in other areas may not be as high. This is due to factors such as climatic conditions, soil adaptability, and the development of agricultural technology. Additionally, the rapeseed harvest is highest in Hokkaido, indicating agricultural specialization and regional productivity differences between regions. In the future, it will be important to take advantage of the characteristics of production areas, particularly Hokkaido, and introduce effective production plans and technologies.
The maximum is 3.07kt of Hokkaido, the average is 380t, and the total is 3.42kt
Rapeseed cultivation area (main data).
The area of rapeseed cultivation in Japanese agriculture has fluctuated between 1958 and 2022. Early data shows that the national area had a record size of 225kha in 1958, but has since shown a declining trend. Current data shows that it has fallen to 773m% of its peak. This trend is thought to be due to several factors, including changes in Japan’s agricultural structure, changes in market demand, and a shift to other crops. Improvements in technology and productivity related to rapeseed cultivation may also be a factor. On the other hand, since the rate of decline is very large, it is suspected that there are issues related to rapeseed production and a decline in competitiveness. Going forward, policies and initiatives will be needed to promote the introduction of efficient production technologies and the recovery of demand.
The maximum is 225kha[1958] of Japan, and the current value is about 773m%
Rapeseed cultivation area (by prefecture).
According to the latest prefecture-by-prefecture data for 2022 regarding the area of rapeseed planted in Japanese agriculture, Hokkaido recorded the largest area overall at 1 kha. This indicates that Hokkaido is a major region for rapeseed cultivation. Hokkaido, with its vast farmland and particularly favorable climatic conditions, offers a favorable environment for rapeseed production. Meanwhile, rapeseed acreage may not be as large in other areas. This is due to factors such as climatic conditions, soil adaptability, and the development of agricultural technology. Additionally, Hokkaido has the largest cultivated area, indicating agricultural specialization and regional productivity differences between regions. In the future, it will be important to take advantage of the characteristics of production areas, particularly Hokkaido, and introduce effective production plans and technologies.
The maximum is 1kha of Hokkaido, the average is 155ha, and the total is 1.4kha
Rapeseed yield per 10a (by prefecture).
According to 2022 data on rapeseed yield per 10a in Japanese agriculture, Hokkaido recorded the highest yield overall at 307kg. The average yield was 95.2kg and the total yield was 857kg. This data shows that Hokkaido has excellent productivity in rapeseed production. Hokkaido, with its vast farmland and particularly favorable climatic conditions, offers a suitable environment for cultivating rapeseed. Meanwhile, other areas may have below average yields per 10a. This is due to factors such as climatic conditions, soil adaptability, and the development of agricultural technology. Hokkaido’s highest yield per 10 ares indicates agricultural specialization and regional productivity differences between regions. In the future, it will be important to take advantage of the characteristics of production areas, particularly Hokkaido, and to spread and support technologies aimed at improving yields in other regions.
The maximum is 307kg of Hokkaido, the average is 95.2kg, and the total is 857kg
