How to proceed with the seven checks for permits and approvals required for solar power plant construction

In solar power plant construction, multiple issues proceed simultaneously: site formation, racking, panels, electrical equipment, grid connection, and neighborhood explanations. Therefore, if you try to handle permit and approval checks as separate application tasks in the background, omissions tend to be discovered just before construction starts, causing the entire schedule to stop. In practice, certification under the Special Measures for Renewable Energy (RE Special Measures Act), land-use related laws, environmental/landscape/cultural property issues, municipal ordinances, resident briefings and notifications, and notifications under the Electricity Business Act often overlap in parallel, so it is important to design the confirmation order in advance. ANRE +2 ANRE +2

Another point to note is that certification under the RE Special Measures Act and permits/approvals under various laws and ordinances are separate matters. The Agency for Natural Resources and Energy’s guideline for solar power makes clear that certification does not guarantee compliance with other laws and ordinances, and that it is necessary to identify and prepare the procedures required under related laws and ordinances in advance. In some projects, certain land development permits and approvals must be obtained before submitting a new application, and post-certification changes to the plan can affect price categories and schedules. ANRE +1

Additionally, confirmation items vary greatly depending on the site. For forests, a forest land development permit may be required; for agricultural land, farmland conversion; for sites within a national park, the Natural Parks Law; for areas with buried cultural properties, notification under the Cultural Properties Protection Law; for projects above a certain scale, environmental impact assessment; and ordinances may impose landscape or natural environment protection zones and resident briefing requirements. Therefore, permit and approval checks should be seen not as application document preparation work but as management work to determine the constraint conditions up to the start of construction by overlaying site conditions on maps and regulatory systems.

Why permit and approval checks become difficult in solar power plant construction

Permit and approval checks are difficult in solar power plant construction because no single regulation alone is sufficient to make a determination. Confirmation targets spread across land classification, whether the site falls under forest land, the scale of site formation, details of embankment and cutting, surrounding disaster risk zones, whether the site is subject to natural park or landscape ordinances, the presence of buried cultural properties, need for resident briefings, and grid interconnection and Electricity Business Act procedures. Moreover, even for similar solar projects, required checks differ greatly depending on whether the facility is being installed on flat idle land, on farmland as agrivoltaics, or requires earthworks involving forested areas. meti.go.jp +4 ANRE +4 Forestry Agency +4

Another difficulty is that national systems alone do not complete the picture. The Agency for Natural Resources and Energy’s FY2026 FIT/FIP guidebook shows that forest law, embankment regulation law, the three erosion-control laws, sediment disaster warning zones, and ordinance-based protection areas are involved in judgments about whether briefings are required, and that violations of relevant laws or ordinances can affect certification. In other words, construction managers must not assume “if we get national certification we can start construction,” but must build confirmation workflows that include municipal zoning, ordinances, and coordination with local administrative points of contact. ANRE +2 ANRE +2

Therefore, in practice it is more efficient to first cross-sectionally organize the site attributes and then deepen checks in the order of site formation, land use, environment, resident response, and electrical equipment, rather than progressing permit and approval checks in vertical silos by law. If you start preparing applications without grasping the site conditions, issues such as farmland, forest, embankment regulations, and buried cultural properties may surface later, causing major rework in both schedule and design. It is important to understand that permit and approval checks are not document preparation work but the task of solidifying the prerequisites for the construction plan. ANRE +2 Forestry Agency +2

Item 1: First clarify the relationship between RE Special Measures Act certification and other laws

The first item to confirm is to clarify the relationship between certification under the RE Special Measures Act and permits/approvals under other laws. The Agency for Natural Resources and Energy’s guideline for solar power indicates that certification and permits/approvals under related laws and ordinances are conducted from different perspectives, and that certification does not guarantee those permits/approvals. Moreover, in some projects, certain land development permits and approvals must be obtained before submitting a new certification application, so at the time you start preparing the certification application you should identify which laws will constitute preconditions. ANRE +1

A common practical mistake is to center the program on the certification application and chase other law confirmations afterward. However, if you later find that forest land development permits, farmland conversion, embankment regulation, environmental assessments, or ordinance procedures are needed, the project boundary, output, equipment layout, and site formation content may change, shaking the very premises of the certification. Furthermore, post-certification changes may, depending on their content, affect price categories and reference prices, so unresolved permit issues are not merely schedule delays. At the initial stage, organize the preconditions for certification and the preconditions under other laws in a separate table. ANRE

What you should capture in this item is to lineup certification, permits/approvals, briefings, connection, and start of works along a single timeline. Rather than a schedule just for certification, visualize which permits need to be confirmed by when, which applications should be submitted first, and which conditions must be met before construction can start—this reduces rework. The starting point for permit and approval checks is not memorizing the systems but correctly understanding what certification does not substitute for. ANRE +1

Item 2: Overlay land classification, zoning designations, and ordinances on a map and confirm

The second item is to overlay land classification, zoning designations, and ordinances on a map and confirm. In practical permit and approval checks, before listing law names you must first grasp what attributes the target land has. Whether it is farmland, privately owned forest under a regional forest plan, near a protection forest, within a special or ordinary zone of a natural park, in an area containing buried cultural properties, within a sediment disaster warning zone, or subject to municipal protective ordinance areas will greatly change the required procedures. The Agency for Natural Resources and Energy’s FY2026 guidebook also clarifies that such zoning information is involved in judgments about whether briefings are required. ANRE +2 Ministry of the Environment +2

It is important here not only to look at the planned site on the drawings but also to confirm access roads, temporary yards, drainage destinations, cable routes, and the location of substation equipment. Even if you judge that no permits are necessary for the site of the photovoltaic equipment itself, part of a delivery route may require road occupancy or special vehicle passage permits, or the connection route may require river/road/occupancy-related procedures. The Agency for Natural Resources and Energy’s consolidated procedures list also identifies road occupancy permits and special vehicle passage permits as procedures that may be required in renewable energy projects. ANRE +1

Also, do not leave ordinance checks until later. Even if national laws do not require permits, municipalities may have ordinances or guidelines concerning landscape, natural environment, resident briefings, or protection areas. The materials related to the RE Special Measures Act amendments clearly indicate that related laws include ordinances. Therefore, when checking land classification and zoning designations, you must cross-check not only city planning maps, farmland information, and forestry information but also municipal renewable energy ordinances, landscape ordinances, and conservation ordinances. Only by overlaying maps and regulations will the full scope of permits and approvals to be checked become apparent. ANRE +1

Item 3: Review need for development permits, embankment regulation, erosion control, rivers, and roads together with the site formation plan

The third item is to confirm the need for development permits under the City Planning Act, embankment regulation law, erosion-control laws, river and road-related permissions together with the site formation plan. In solar power plant construction, landform changes, embankment/cutting, drainage treatment, and access road improvements are often more likely to raise permit issues than the panels or racking themselves. The Ministry of Land, Infrastructure, Transport and Tourism and the Agency for Natural Resources and Energy materials organize the need to check permits/notifications under the embankment regulation law, development acts under the City Planning Act, and areas subject to the three erosion-control laws as important confirmation items. Ministry of Land, Infrastructure, Transport and Tourism +2 ANRE +2

In practice, first determine the extent of the site formation: where embankment and cutting will occur, how much drainage infrastructure is needed, and whether retaining walls or slope protection are required. Then, in light of regulation area maps and municipal office practices, determine whether development permission is required under the City Planning Act, whether permission or notification is required under the embankment regulation law, and whether consultations or permits are required under erosion-control or river-related laws. If you only inquire about regulations before the site formation plan is finalized, judgments can vary, so always proceed in concert with the design team. Ministry of Land, Infrastructure, Transport and Tourism +1

What is easy to overlook is procedures associated with acts for the work rather than the work itself. For example, use of access roads, conditions on delivery vehicles, road occupancy, river or waterway crossings, and temporary drainage may require separate confirmations apart from certification of the generation equipment. Although these procedures may seem minor as individual items, if left unresolved just before construction they will stop the site. At an early stage of the site formation plan, a checklist of permits and approvals should include not only the equipment installation area but also construction movement lines and drainage lines to prevent schedule delays. ANRE +1

Item 4: Separate checks for the Farmland Law and Forest Law by land attribute

The fourth item is to separate checks for the Farmland Law and Forest Law by land attribute. One of the most influential attributes for solar power plant siting is whether the land is farmland or forest. For farmland, you must confirm early whether farmland conversion permission is required. In particular, for agrivoltaics where posts are placed in farmland so that farming can continue underneath, conversion permission for those posts is required, and from April 2024 temporary conversion permission standards have been positioned in the Farmland Law enforcement regulations and guidelines. If the equipment owner and the farmer are different parties, establishing surface rights or similar may require permission under Article 3 of the Farmland Law. Ministry of Agriculture, Forestry and Fisheries +1

For forests, you must distinguish whether the land is privately owned forest subject to the regional forest plan, whether it falls under protection forest, or coastal protection zones. According to the Forestry Agency, for privately owned forests subject to the regional forest plan, if development acts are undertaken for the purpose of installing solar power equipment, since April 2023 (Reiwa 5) forest land development permission from the prefectural governor is required when the area exceeds 0.5 hectares. Regulation of forest land development related to solar equipment has been tightened in recent years, so judging by the older 1-hectare threshold can lead to mistakes. Forestry Agency +1

Practitioners should be careful not to judge “farmland or forest” based on present sense alone. It is not uncommon for the registered land classification, current condition, zoning designations, and judgments of relevant authorities to diverge. Therefore, early in the process conduct checks by parcel number to determine whether farmland conversion is required, whether agrivoltaics can be applied, how to count area for forest land development, whether integrated development applies, and whether a logging notification is needed. Checking the Farmland Law and Forest Law at the same time as land acquisition, not after design, is extremely important to prevent rework. Forestry Agency +2 Forestry Agency +2

Item 5: Do not postpone natural park, cultural property, and environmental assessment checks

The fifth item is not to postpone checks for natural parks, cultural properties, and environmental impact assessments. These issues are often misunderstood as concerns only for very large projects, but in reality they can greatly affect construction planning and schedules. The Ministry of the Environment explains that in national and quasi-national parks, permission criteria for new, altered, or expanded construction of solar power facilities in special zones and notification criteria for ordinary zones are established, and the specific approach to permit review is guided. Whether the site falls within a natural park area should always be checked in initial site screening. Ministry of the Environment

The same applies to cultural properties. The Agency for Cultural Affairs advises that when development projects such as civil engineering work are carried out in known areas containing buried cultural properties, a prior notification to the prefectural or designated city board of education is required, and as a result of consultation an excavation survey for recording and preservation may be requested. This can directly lead to construction delays and survey cost burdens, so it is a typical item to check before site formation or pile work. It is too late to inquire after the site formation drawings are completed; you should investigate whether the site contains buried cultural properties from the candidate site stage. Agency for Cultural Affairs

Regarding environmental impact assessment, as of April 2026 solar power projects are included under the Environmental Impact Assessment Law: currently First-class projects are those with output of 40,000 kW or more, and Second-class projects are those with output of 30,000 kW or more but less than 40,000 kW. The Ministry of the Environment and the Ministry of Economy, Trade and Industry have announced that they are considering revising scale requirements in 2026, so the threshold may change in the future. For large projects, do not assume “the current size means we are excluded”; check the latest regulatory status and reverse-engineer whether a scoping document is required. Ministry of the Environment

Item 6: Put resident briefings, prior notifications, connection consent, and Electricity Business Act procedures into the schedule

The sixth item is to include resident briefings, prior notifications, connection consent, and Electricity Business Act procedures in the schedule rather than managing them separately from permit and approval checks. Due to amendments to the RE Special Measures Act, certain solar projects now require briefings and prior notification measures, and the Agency for Natural Resources and Energy’s FY2026 guidebook states that briefings should, in principle, be held by three months before the certification application date. Even low-voltage projects require briefings if another project by the same operator or a closely related party exists within 100 m (328.1 ft) from the site boundary and the combined output exceeds a certain threshold. Confirming the need for briefings late will delay the entire certification schedule. ANRE +1

Additionally, the Agency for Natural Resources and Energy advises that submission of grid connection consent documents and compliance with related laws including ordinances may be required to meet certification criteria. Therefore, do not manage grid interconnection prospects, completion timing for briefings and prior notifications, ordinance procedures, and the certification application timing separately. In practice, overlay connection consent, neighborhood briefings, certification application, site formation permits, and start of works on a single schedule so that when one item is delayed you can see what else will be impacted. ANRE +2 ANRE +2

Another commonly overlooked item for construction managers is notifications under the Electricity Business Act. The Ministry of Economy, Trade and Industry requires operators of small-scale commercial electrical installations to submit basic information before start of use and a notification of the results of self-inspection before use. For solar, initial guidance indicated equipment of 10 kW or more and less than 50 kW are subject, and if self-inspection before use and the notification are not incorporated into the schedule, procedural deficiencies may be discovered just before completion. Permit and approval checks often focus on land-related procedures, but electrical-equipment-side notifications and confirmations should also be incorporated early as conditions for completion. meti.go.jp +1

Item 7: Eliminate pre-construction outstanding items with a permit/approval ledger and change management

The seventh item is to create a permit/approval ledger and a change management mechanism to eliminate outstanding items before construction starts. In solar power plant construction, even if you know the relevant systems, omissions occur when it is unclear who will submit what to which office by when and with which drawings and materials. An effective measure is to create a permit/approval ledger that centrally manages not only the law name but also the target scope, responsible person, competent office, pre-consultation date, application conditions, attachments, expected review period, relationship to construction start, and whether reconsultation is required upon changes. This functions not merely as a management table but as a list of construction start conditions. ANRE +1

Change management is particularly important. The Agency for Natural Resources and Energy’s guideline notes that post-certification plan changes may, depending on their content, affect price categories or treatment of reference prices. In practice, slight adjustments in equipment location, output changes, changes to the site formation area, access road changes, or changes to the scope of resident briefings can occur. If these are handled as “on-site adjustments,” rechecks on the permit/approval side can easily be omitted. When a change occurs, the ledger should allow you to determine which permits require reconsultation and which drawings need replacement. ANRE +1

Also, do not be lenient in judgment on whether construction can start. Distinguish items that are acceptable to proceed with while “applied for” or “under consultation” from those that formally require completed permits or notifications. Sites with a permit/approval ledger can visualize outstanding items and make clear start-of-construction decisions. Conversely, sites without a ledger tend to rely on implicit knowledge held by someone, and omissions often surface at the last minute. In the final stage of permit and approval checks, management that reduces outstanding items to zero is more important than regulatory knowledge. ANRE +1

Common features of sites that tend to fail in permit and approval checks

Having reviewed the seven items, common features of sites that tend to fail in permit and approval checks emerge. First, a common mistake is placing too much weight on certification under the RE Special Measures Act. As certification preparation progresses, teams often assume other laws and ordinances will somehow be resolved, but farmland, forests, natural parks, cultural properties, embankment, and resident briefings operate under separate systems. Misunderstanding the relationship between certification and other laws makes design changes and construction delays likely. ANRE +1

Second, many teams only look at the main site. If you do not check access roads, material yards, drainage destinations, cable routes, substation equipment, and the scope for resident briefings, omissions occur in road occupancy, resident notification, drainage matters, and cultural property inquiries. A solar power plant is not a business that exists only on “the surface where panels are placed”; you must consider the surrounding space used for construction when checking permits. ANRE +2 Agency for Cultural Affairs +2

Third, treating regulatory checks as legal work is a mistake. Permit and approval confirmation are inseparable from the construction plan. If the scale of site formation changes, development and embankment judgments change; if land classification or zoning changes, farmland, forest, natural park, and briefing targets change; and if output or layout changes, certification and Electricity Business Act procedures are affected. Therefore, do not leave it only to the permit/approval person; design, construction, land acquisition, and electrical staff need to proceed looking at the same drawings. Sites where these functions are split experience more omissions. Ministry of Land, Infrastructure, Transport and Tourism +2 Forestry Agency +2

Practical perspectives to connect permit and approval checks to construction management

What matters in linking permit and approval checks to construction management is the order of confirmation rather than the volume of regulatory knowledge. First separate certification and other laws, then confirm land attributes and zoning designations on a map, and then resolve checks in the order of site formation, land attribute-related, environment/landscape, and resident briefings/electrical. This approach helps you grasp impacts on design and schedule earlier. Conversely, repeatedly seeking individual consultations by law makes it hard to see where each procedure fits in the overall schedule and is difficult to manage. ANRE +2 ANRE +2

Permit and approval checks do not end with construction preparation. During construction, boundary fine-tuning, changes to the site formation extent, output revisions, equipment position changes, and access road changes may occur. If a mechanism exists to return to legal confirmations when changes arise, issues remain small. Sites strong in construction management control permit matters not by whether permits were “obtained” but by whether they can “return to regulatory checks when changes occur.” ANRE +1

Moreover, sites that operate permit and approval checks well tie resident briefings and administrative consultations into the schedule. Briefings and prior notifications should not be rushed right before certification application or construction start; they are most effective when presented alongside site formation and delivery plans and noise and dust countermeasures. When the regulatory system is separated from field operations, documentation may be complete but practical obstacles arise on site. The true purpose of permit and approval checks is not to get an application approved but to create conditions that prevent construction from stopping. ANRE +1

Permit and approval checks for solar power plant construction become easier by organizing location information

For permit and approval checks required for solar power plant construction, basic steps are: separating RE Special Measures Act certification from other laws, cross-checking land attributes and zoning designations, determining need for site formation permits, checking Farmland Law and Forest Law, identifying natural park/cultural property/environmental assessment issues, scheduling resident briefings and Electricity Business Act procedures, and establishing a permit/approval ledger and change management. Proceeding in this order reduces omissions and significantly lowers uncertainty at construction start. meti.go.jp +4 ANRE +4 ANRE +4

In practice it is particularly important to quickly share on-site which zones are subject to which regulations, what the scope of target areas is, and whether to include access roads and drainage destinations in the scope for administrative consultations and resident briefings. Sites that delay permit and approval checks often fail not from lack of regulatory knowledge but because building a shared recognition of the target scope takes time. When location information is organized and stakeholders can discuss using the same map and the same scope recognition, administrative consultations and design adjustments proceed more smoothly. ANRE +1

In that sense, in large solar power plant sites visualizing locations affects the speed of permit and approval checks. In situations where you need to quickly confirm zone classifications, boundaries, and share the site formation extent and briefing target areas on site, using systems such as LRTK (iPhone-mounted GNSS high-precision positioning device) can help align stakeholders’ positional recognition. Such tools do not substitute for permits and approvals themselves, but for practitioners who want to improve the accuracy of on-site confirmation and information sharing, they can be a useful means to advance pre-construction organization. Do not leave permit and approval checks at mere regulatory confirmation; advance them early as preparations to prevent construction stoppage—this is critical in solar power plant construction.
