The study sought to examine the effect of climate change on agricultural productivity in Japan. The study adopted the cross-section research design. Questionnaires were used to collect the data. The respondents included farmers and officials in Japan's Ministry of Agriculture, Forestry and Fisheries. The study indicated the negative and significant correlation between agricultural productivity and climate change. Climate change was found to be satisfactory in explaining agricultural productivity in Japan. The results indicated that climate change is a good predictor of agricultural productivity. The regression results showed that climate change is negatively and significantly related to agricultural productivity. The results implied that when the climate change deteriorates by one unit, the agricultural productivity will reduce by 0.327 units holding other factors constant. The effect of climate change is frequent wildfires, more extended periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. The study recommended there is a need to focus on planet-friendly investments. Individuals can spur change through savings and investments by choosing financial institutions that do not invest in carbon-polluting industries. The government needs to accomplish sensitization program awareness on cause, influence, reduction and adjustment to environmental change. The government needs to additionally urge the adoption of smart agriculture where farmers do not count on rain feed agriculture but on scientific agriculture. It should provide farmers with drought-resistant seeds and livestock to improve production and ensure food security in Japan. Technological development can decrease the unfavorable effects of weather irregularity and might affect global adaptation efforts favoring various nations. There should be an emphasis on more tree planting in the country.
