The forecast for watermelon yield in Japan from 2024 through 2028 shows a steady, yet very slight, decline in productivity per hectare from 323.53 thousand hectograms in 2024 to 322.93 thousand hectograms in 2028. Comparatively, the yield in 2023 was slightly higher, indicating a small downward trend. Year-on-year percentage variations are minimal, showing stability but a negative trajectory, with a five-year Compound Annual Growth Rate (CAGR) reflecting a similar modest decline.

Future trends to watch for include:

Changes in agricultural practices that could improve watermelon yield.
The impact of climate change and weather patterns on overall production levels.
Innovations in seed quality or farming technology that could reverse the yield decline.
