Abstract
We will examine the harvest volume, planting area, and yield per 10a of peanuts in Japanese agriculture based on data from 2022. The national groundnut harvest is 17.5kt and the cultivated area is 5.87kha. In addition, the yield per 10a in Chiba is 312kg. The trends inferred from these figures suggest that harvest volumes are stable across the country and that the area planted is showing a slight upward trend. Furthermore, since the yield per 10a is the highest in Chiba, there is a possibility that production efficiency is high in this region. This is thought to be due to Chiba’s climatic conditions being suitable for cultivating peanuts and advances in agricultural technology. Overall, it can be said that peanut production is stable nationwide, with some regional differences in production efficiency.
Peanut harvest yield (main data).
Peanut harvest volumes in Japanese agriculture have fluctuated throughout data from 1905 to 2022. The highest overall harvest recorded by the prefecture was 144kt in 1963, and since then it has declined to 10.8% of the peak. This may be due to structural changes in agriculture, technological innovation, and changes in the local environment. Over the past few decades, urbanization and industrial development have led to a decline in farmland, as well as issues such as labor shortages, which have also affected groundnut production. Changes in agricultural policies and international market factors may also contribute to yield fluctuations. Overall, groundnut yield has undergone historical changes, with various factors influencing its characteristics and trends.
The maximum is 144kt[1963] of Japan, and the current value is about 12.2%
Peanut harvest volume (by prefecture).
According to data from 2022, the largest peanut harvest in Japan was in Chiba Prefecture, at 14.9kt. This value broke the previous record and is now the highest value. This trend may be due to advances in agricultural technology, improved production efficiency, and the presence of suitable climatic conditions in Chiba Prefecture. Peanut production may also be increasing in other prefectures, which is likely the result of technological innovation in agriculture as a whole and government support measures. Overall, Japan’s peanut harvest is expected to reach its highest level ever in 2022, with agricultural development and technological innovation contributing to increased productivity in each region.
The maximum is 14.9kt of Chiba, the average is 14.9kt, and the total is 14.9kt
Peanut planted area (main data).
When examining data from 1905 to 2022, the area of land cultivated with peanuts in Japanese agriculture shows fluctuations. The highest total recorded by prefectures was 66.5kha in 1965, and since then it has declined to 9.04% of the peak. This trend may be due to changes in agricultural land use, shifts in agricultural structure, and increasing urbanization. It is believed that the migration of population to urban areas and the advancement and industrialization of agriculture over the past few decades have led to a reduction in the area of peanut cultivation. Changes in agricultural policies and international market demand may also be affecting acreage. In general, groundnut planted area has undergone historical changes, and various factors have influenced its characteristics and trends.
The maximum is 66.5kha[1965] of Japan, and the current value is about 8.83%
Peanut cultivation area (by prefecture).
According to data from 2022, the largest peanut planted area in Japan is in Chiba Prefecture, at 4.79 kha. This value breaks the previous record and is now the highest value. This trend may be due to advances in agricultural technology, improved production efficiency, and the presence of suitable climatic conditions in Chiba Prefecture. Additionally, the area of land cultivated with peanuts may be increasing in other prefectures as well, which is likely the result of technological innovation in agriculture as a whole and government support measures. Furthermore, with the population moving to urban areas and agriculture becoming more advanced, it is possible that certain regions are placing emphasis on groundnut production. Overall, Japan’s peanut planted area is expected to reach its highest level ever in 2022, suggesting that while there are regional productivity improvements, there are also regional differences.
The maximum is 4.79kha of Chiba, the average is 4.79kha, and the total is 4.79kha
Peanut yield per 10a (by prefecture).
According to data from 2022, the highest yield of peanuts per 10a in Japan is in Chiba Prefecture, at 312kg. The average value is also 312kg, and the total value is also 312kg. This indicates that groundnut productivity is stable across the country. Additionally, the fact that Chiba Prefecture recorded the highest yield may suggest that agricultural techniques and production management in this region are more advanced. Since the average yield per 10 ares and the total value are the same, it can be inferred that there are areas nationwide that are achieving high yields and that the average yield is maintained above a certain level. It is believed that improvements in agricultural productivity and technological innovation are behind this stable yield. Overall, the yield of peanuts per 10a in Japan is stable in 2022, and it is notable that high yields have been achieved in some areas, including Chiba Prefecture.
The maximum is 312kg of Chiba, the average is 312kg, and the total is 312kg
