A portal page from Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) that links to yearly estimates (from FY2008 onward) of annual food waste generation and food recycling implementation rates. It explains the estimation method — combining mandatory reports from businesses generating 100+ tonnes/year with estimates for smaller businesses — and links to each fiscal year's detailed PDF or e-Stat data.

MAFF's FY2024 estimate of food waste generation and food-recycling implementation rates across Japan's food industry. Total annual generation was 14.634 million tonnes (up 2.6% year on year), with an overall recycling implementation rate of 91% (98% for manufacturing, 63% wholesale, 65% retail, 35% food service). By end use, 76% of recycled material became animal feed and 14% became fertilizer.

Japan's Ministry of the Environment survey results, published March 27, 2026, on FY2024 nationwide municipal solid waste generation and disposal. Total waste generation was 38.11 million tonnes (down 2.2% year on year), the recycling rate was 19.3%, and final disposal volume was 3.06 million tonnes. The number of incineration facilities fell to 991, while those with power generation equipment rose to 415, generating 10,448 GWh in total.

Taito Ward partners with Daimaru Matsuzakaya and Local Food Cycling to sell subsidized home compost containers and run collection events for circular food-waste use. Over the one-year period from December 2024 to November 2025, the ward reports about 5.4 tons of food waste reduction and about 2.6 tons of CO2 reduction.

This research investigated factors encouraging Japanese households to engage in composting, applying the theory of consumption values (TCV) and evaluating hypotheses using ordinal partial least squares structural equation modeling. Findings indicate that household composting in Japan is influenced by social approval, behavior visibility, composting knowledge, convenience, interest in gardening/farming, and individual availability. Factors like emotions, gender, housing type, and household size did not significantly impact composting practice.

A press release from Japan's Ministry of the Environment summarizing FY2023 nationwide municipal solid waste generation and disposal. Total waste generation was 38.97 million tonnes (down 3.4% year on year), the recycling rate was 19.5%, and final disposal volume was 3.16 million tonnes. Of 1,004 incineration facilities, 411 had power generation equipment, generating 10,254 GWh in total.

Japan's Consumer Affairs Agency published its FY2023 food loss estimate on June 27, 2025. Total food loss was 4.64 million tonnes, down from 4.72 million tonnes the prior year, split between 2.31 million tonnes from businesses and 2.33 million tonnes from households.

Japan's Ministry of the Environment estimates FY2023 food loss at about 4.64 million tonnes (2.33 million tonnes household, 2.31 million tonnes business), down from 4.72 million tonnes the previous year. Under the Food Loss Reduction Promotion Act's basic policy, Japan targets halving household food loss and cutting business food loss 60% by FY2030, both against a FY2000 baseline.

Demonstrates that per-capita household food waste in Japan rises with the age of the household head, reaching roughly three times higher for those 70+ than for those under 30, with correspondingly large differences in food-waste-related greenhouse gas emissions. It highlights the need for age-targeted food-loss reduction strategies in an ageing society.

On 21 June 2024, Japan's Ministry of the Environment published its estimate of national food loss for FY2022 (Reiwa 4), totaling approximately 4.72 million tonnes (2.36 million tonnes from businesses, 2.36 million tonnes from households), down about 510,000 tonnes from FY2021's 5.23 million tonnes (2.79 million business, 2.44 million household). The government's goal is to halve food loss by FY2030 relative to FY2000 levels.

On 21 June 2024, Japan's Ministry of Agriculture, Forestry and Fisheries announced that business-sector food loss for FY2022 fell to 2.36 million tonnes, meeting the national target of halving business food loss from the FY2000 baseline of 5.47 million tonnes to 2.73 million tonnes by FY2030. This is a decrease of 430,000 tonnes (15.4%) from the prior year's 2.79 million tonnes.

Analyzes nationwide survey data to identify consumer attributes (gender, age, children in the household, safety awareness) and behaviors (checking labels, food management) associated with household food-waste generation and reduction in Japan. It shows that contributing factors differ between large cities, small cities, and rural areas, underscoring the need for region-specific measures.

This Consumer Affairs Agency page summarizes Japan's Food Loss Reduction Promotion Act, promulgated 31 May 2019 and enforced from 1 October 2019, which sets out national and local government responsibilities and the framework for a basic policy on reducing food loss. A second basic policy was adopted by cabinet decision on 25 March 2025.

Jiménez-Antillón, J., Calleja-Amador, C., Romero-Esquivel, L. G. · Resources (MDPI), 7(4):84 · Global (Costa Rica; Japan-origin method)

A field study placing the Kitakyushu-origin 'Takakura' composting method—widely diffused in Surabaya, Indonesia—as small portable boxes in university offices and workplaces in Costa Rica. Processing food waste from 45 staff over six months, it shows that low-cost, citizen/workplace-scale fermentation composting is viable.
