Japan’s Green Farming Push Goes Global. Can It Work on the Farm?

A farming technology can perform well in a trial and still fail to become a business. Someone must be able to operate it, maintain it and pay for it through another growing season. If its value includes a smaller environmental footprint, someone must also be able to demonstrate that benefit.

Japan’s revised MIDORI∞INFINITY initiative is an attempt to connect those tasks. On September 17, the Ministry of Agriculture, Forestry and Fisheries broadened its overseas technology package from greenhouse-gas reduction to green transformation, or GX. Climate adaptation, circular use of resources and biodiversity now sit alongside emissions mitigation in its stated scope.^[1]

The change creates a larger field of opportunity for technology suppliers, researchers and overseas producers. It also raises a harder question: how should Japan judge success when the benefits range from lower methane emissions to more reliable harvests? Reading the policy alongside the underlying research suggests that local suitability and credible evidence will matter as much as the technology itself.

A broader proposition than carbon alone

The September announcement highlights biostimulants, plant factories, land-based aquaculture, forest-based disaster-risk reduction and the reuse of underutilized resources and by-products. It also adds country-level analysis of emissions-reduction potential and information on support and financing.^[1]

These activities solve different problems. Mitigation addresses the causes of climate change by reducing emissions or increasing removals. Adaptation addresses its consequences for production. A technology may help with both, but one benefit does not establish the other.

For an overseas buyer assessing a controlled production facility, for example, a useful evaluation would examine reliable output, energy and water requirements, operating costs and environmental performance together. That is an analytical test, not a finding about a particular installation. The wider GX category makes such distinctions more necessary: a common policy label cannot substitute for a project-specific comparison.

How the overseas initiative developed

The policy lineage begins with Japan’s Strategy for Sustainable Food Systems, known as MIDORI, adopted on May 12, 2021. It sought to reconcile productivity and sustainability through innovation. A supporting law took effect in July 2022, providing a domestic policy foundation for efforts to reduce environmental burdens.^[2]

International research cooperation supplied another foundation. The Japan International Research Center for Agricultural Sciences, or JIRCAS, and partner institutions assembled a technology catalog for the Asia-Monsoon region. Its rationale includes shared features such as hot, humid conditions, rice cultivation and the importance of smaller farms. Its introduction explicitly anticipates local optimization and adjustment, rather than assuming technologies can be transferred unchanged.^[3]

MAFF published the first MIDORI∞INFINITY package on May 30, 2025, after releasing an outline in April and consulting businesses and researchers. That initial version focused on emissions-reduction approaches compatible with food security and brought together routes for research and deployment support.^[4]

The initiative then evolved in stages. Version 1.1, in February 2026, added technologies and support information; Version 1.2, in April, reflected the approved fiscal 2026 budget. September’s Version 2.0 broadened the framework to GX. The ministry’s revision history already lists biostimulants in the February update, an important reason not to describe every technology mentioned this September as newly introduced.^[5]

A related but distinct document, MIDORI BOOST, was adopted on June 25, 2026. It sets out measures for concentrated action toward 2030 under the wider food-systems strategy. MIDORI∞INFINITY is the overseas technology package; the two names should not be treated as interchangeable programs.^[6]

The rice-field test: does the practice work here?

Rice water management shows why deployment is more complicated than exporting a machine. Alternate wetting and drying, or AWD, allows fields to dry between periods of flooding. Developed by the International Rice Research Institute for water saving, it is an internationally shared practice to which Japanese research has contributed, not an exclusively Japanese invention.^[7]

A NARO research summary reports three years of field experiments at four Southeast Asian locations. Average methane reduction against continuous flooding was 31 percent. But drainage was sometimes difficult during the rainy season, and the researchers caution against assigning reductions where AWD cannot actually be implemented.^[7]

Japan’s practice of extending midseason drainage provides a separate example. A NARO technology sheet describes trials at nine Japanese locations in which an additional week of drainage reduced methane by roughly 30 percent on average without affecting yield or grain protein content.^[8] These are distinct bodies of research, not two descriptions of one universal result.

The business implication is practical. Before promising an environmental return, a project needs to establish who controls drainage and irrigation, how water decisions are coordinated and whether the farmer can follow the required schedule. A technically convincing average does not answer those local questions. The service around a technology may determine whether its research promise survives a difficult season.

Better use of nitrogen—and better measurement of carbon

Biological nitrification inhibition, or BNI, offers a different route. Plants release substances that inhibit the soil process converting ammonium into nitrate. A JIRCAS technology sheet describes BNI-enhanced wheat trials in which cutting nitrogen fertilizer by 60 percent produced no significant yield difference against the comparator. The same sheet warns that soil conditions, including pH, influence performance.^[9]

This is a reason to investigate locally adapted crops, not a general instruction for farmers to cut fertilizer by that amount. The commercial question is whether the benefit can be reproduced under the buyer’s conditions while maintaining the quality that buyers of the harvested crop require.

Biochar illustrates the importance of assessment costs. A catalog entry from researchers including Ritsumeikan University describes a method using proximate industrial analysis to estimate carbon retained in agricultural soils, with bamboo and unused woody biomass as examples. It addresses the cost and complexity of characterizing the material.^[10]

A tonne of biochar applied to a field is not automatically a tonne of carbon dioxide removed. Reliable characterization is part of the product’s usefulness. That suggests opportunities beyond manufacturing equipment: testing, quality assurance and methods that make environmental claims easier to substantiate can also help a project function.

Biostimulants bring another evidence question. The package describes materials intended to support crop or soil functions, including tolerance of heat and drought and improved nutrient use. It points to MAFF guidance requiring evidence behind claims about their effects.^[11] For a prospective user, the useful questions concern the particular material, crop, application and trial conditions—not simply whether a product carries the category’s name.

When an emissions reduction becomes a credit

Japan’s Joint Crediting Mechanism, or JCM, is one route for linking international cooperation to carbon finance. MAFF describes it as a system in which Japan and a partner country cooperate through technology and funding, then allocate achieved reductions or removals according to their contributions. Quantities are conservatively calculated and approved by both governments, with accounting arrangements to prevent the same transferred amount being counted toward both countries’ targets.^[12]

There is a concrete milestone for rice: on February 3, 2025, the Japan–Philippines joint committee approved AWD methodology PH_AM0042.^[13] A methodology establishes the rules for quantifying a result. Its approval does not itself demonstrate that a particular farmer has earned income or that a project has received credits.

The revised package also identifies measurement, reporting and verification—MRV—as enabling infrastructure.^[11] This connects farm activity to evidence that other parties can assess. It creates a potential role for providers of monitoring systems and local support, alongside the suppliers of agricultural technologies.

Our assessment is that the allocation of costs deserves as much attention as the allocation of credits. Who pays for records and verification? Who takes the risk if results disappoint? How much of any additional revenue reaches the farmer? A durable project should explain ordinary production income, changes in operating costs and prospective credit proceeds separately. Combining them into one optimistic return obscures what makes the activity viable.

Finance and partnerships are part of deployment

The official overview brings together feasibility work, local demonstration, research, government coordination, business matching and financing tools.^[14] Their inclusion makes the package a route through multiple support systems. It should not be read as a commitment to fund every listed technology or prospective project.

The renamed Midori GX Overseas Development Consortium is another part of that approach. MAFF’s September 7 notice for a September 17 meeting set out technology presentations, a discussion of finance’s role in commercialization and overseas expansion, and networking. The announced agenda shows the emphasis on assembling projects; it does not establish their subsequent commercial results.^[15]

For a supplier, the opportunity is therefore larger than a first equipment sale. A credible offer may need local maintenance, consumable supplies, training and a plan for responding during a critical growing period. For a research institution, cooperation is most valuable when it can explain failure as well as demonstrate success. For farmers, the central question remains whether the change leaves them better able to produce and earn.

This is Japan.co.jp’s analytical framework for following implementation, not a scorecard of results already achieved.

What success would look like after the launch

The strongest evidence would follow a technology beyond its introduction: repeated use over growing seasons, maintained output and quality, environmental results that can be checked, and a financial benefit that remains after the pilot’s support ends. Country-level potential is useful for identifying where to investigate. It is not a substitute for these outcomes.

The link to Japan’s own food security also needs a precise reading. More resilient production overseas may strengthen supply chains, but it does not establish an immediate reduction in Japanese grocery prices. Supplier revenue, host-country farm income and benefits to consumers are different outcomes that deserve separate scrutiny.

MIDORI∞INFINITY’s revision gives Japan a broader basis for international agricultural cooperation and business development. Its eventual significance will depend on how well institutions and companies connect technology to the conditions of use. A farmer choosing to continue after the demonstration ends will tell a more persuasive story than another addition to a catalog.
