The TNFD LEAP framework starts with "Locate" — but where exactly in Japan are your nature dependencies? Most companies struggle with this first step, producing vague statements about "relying on ecosystems" without identifying specific locations.
This guide shows how to map nature-related locations for TNFD disclosure, using Japan as a case study with real infrastructure that makes location-based natural capital actionable.
tl;dr
To map nature-related locations: Identify your interface points with nature (operations, supply chain, investments), classify them by ecosystem type, and connect them to specific geographic units. Japan comprises one bioregion and seven distinct ecoregions — each with different ecosystem characteristics and service flows.
the LEAP "locate" phase
TNFD's LEAP approach (Locate, Evaluate, Assess, Prepare) starts with identifying where your organization interfaces with nature. This seems straightforward until you try to do it.
The challenge: "We depend on water" is not a location. "We depend on water from the Tone River watershed, which flows through Taiheiyo evergreen forests and supplies our Kanto manufacturing facilities" is.
| Interface Type | What to Map | Example |
|---|---|---|
| Direct operations | Facilities, land holdings, infrastructure | Factory sites, office buildings, owned forests |
| Upstream supply chain | Sourcing locations, supplier facilities | Agricultural inputs, raw material origins |
| Downstream | Product use locations, disposal sites | Customer markets, end-of-life processing |
| Investments | Portfolio company locations, financed assets | Real estate holdings, project finance sites |
japan's ecological geography
Japan is not a single ecosystem. It spans from subarctic Hokkaido to subtropical Okinawa, with distinct ecological zones shaped by latitude, altitude, and the Japan Sea vs Pacific Ocean divide.
one bioregion
Japan Forest Islands encompasses the entire Japanese archipelago as a coherent biogeographic unit — the scale at which major evolutionary and ecological patterns operate.
seven mainland ecoregions
Within this bioregion, Japan contains seven distinct ecoregions on the main islands:
| Ecoregion | Location | Dominant Ecosystem |
|---|---|---|
| Hokkaido Deciduous Forests | Hokkaido lowlands | Temperate broadleaf deciduous |
| Hokkaido Montane Conifer Forests | Hokkaido mountains | Boreal/subalpine conifer |
| Nihonkai Evergreen Forests | Japan Sea coast, Honshu | Temperate evergreen broadleaf |
| Nihonkai Montane Deciduous Forests | Japan Sea side mountains | Temperate montane deciduous |
| Taiheiyo Evergreen Forests | Pacific coast, Honshu | Warm-temperate evergreen |
| Taiheiyo Montane Deciduous Forests | Pacific side mountains | Temperate montane deciduous |
| Honshu Alpine Conifer Forests | Central mountain ranges | Subalpine conifer |
Additional ecoregions cover the Nansei Islands (subtropical) and Ogasawara Islands (oceanic subtropical).
Why this matters: Different ecoregions provide different ecosystem services. A company dependent on water from Hokkaido faces different risks than one dependent on water from the Kanto plain (Taiheiyo). TNFD disclosure should reflect this specificity.
how japanese companies are mapping locations
Several early TNFD adopters in Japan have demonstrated location-based approaches:
japan airlines — route-based sensitivity mapping
JAL applies TNFD/LEAP to identify sensitive locations along its global route network. The company has identified specific high-biodiversity destinations including Hawaii and Australia, where it runs targeted conservation programs.
Location approach: Map routes to biodiversity hotspots, then assess impacts and dependencies at destination airports and surrounding ecosystems.
Programs identified: Coral propagation (Okinawa, Hawaii), crane conservation (Hokkaido), tourism-resource protection at destinations.

softbank — infrastructure proximity surveys
SoftBank conducts proximity surveys for telecom base stations near high-biodiversity areas. The company aims to avoid base-station development in sensitive zones where possible, and to minimize and restore impacts when development is unavoidable.
Location approach: GIS-based assessment of infrastructure proximity to critical biodiversity zones, with proactive siting decisions.

seibu holdings — company-owned land inventory
Seibu Holdings has set a target of designating 30% of company-owned land for environmental conservation by FY2030. The company maintains group-owned forests and satoyama (traditional managed landscapes), and engages in wildlife rescue and habitat enhancement around facilities.
Location approach: Comprehensive inventory of owned lands, classification by conservation potential, stakeholder engagement including local communities.

suntory — watershed-based water stewardship
Suntory's Natural Water Sanctuary program protects watersheds that supply its beverage production facilities. The company has identified specific water sources across Japan and implemented conservation programs at each.
Location approach: Trace water inputs to source watersheds, then invest in forest and wetland conservation at those specific locations.

tools for location mapping
Several tools support TNFD location identification:
| Tool | Purpose | Best For |
|---|---|---|
| ENCORE | Sector-ecosystem dependency mapping | Initial screening of likely dependencies |
| IBAT | Biodiversity data for specific sites | Assessing proximity to protected areas, key biodiversity areas |
| WWF Risk Filter | Water and biodiversity risk by location | Supply chain screening |
| H3 / S2 | Geospatial indexing systems | Precise location referencing at multiple scales |
Recommendation: Start with ENCORE to identify which ecosystem services your sector depends on, then use IBAT and WWF Risk Filter to assess specific sites.
from mapping to investment
Identifying locations is necessary but not sufficient. The gap in most TNFD implementations is the bridge from disclosure to action — from knowing where your dependencies are to actually investing in those ecosystems.
the infrastructure gap
Most location-mapping exercises end with a report. What's missing is infrastructure that connects identified locations to ongoing protection:
- Binding mechanisms — Ways to formally connect your organization to specific natural assets
- Funding flows — Channels for continuous investment, not one-time grants
- Verification systems — Ongoing monitoring that confirms ecosystem health
- Geographic precision — Location references that persist and compound value over time
what place-based infrastructure looks like
Ensurance provides this missing layer. Natural assets can be registered with specific geographic extent. Agents can be created with place metadata that ties them to bioregions, ecoregions, or individual properties. Certificates bind directly to named locations.
For Japan specifically, the protocol includes:
- japan-forest-islands.bioregion — representing the archipelago-scale biogeographic unit
- Seven ecoregion agents representing distinct ecological zones:
These agents have onchain accounts that can receive funding, hold assets, and channel investment to the ecosystems they represent.
step-by-step: mapping your locations
step 1: inventory your interface points
List all locations where your organization touches nature:
- Owned/leased facilities
- Key supplier locations
- Raw material sourcing regions
- Customer markets with nature dependencies
- Investment portfolio locations
step 2: classify by ecosystem type
For each location, identify the dominant ecosystem using the 15 ecosystem stock categories:
| Stock Category | Japan Examples |
|---|---|
| Temperate Forests | Most of Honshu, Shikoku, Kyushu lowlands |
| Boreal Forests | Hokkaido highlands |
| Coastal Systems | All coastlines, especially Seto Inland Sea |
| Rivers & Lakes | Tone, Shinano, Yoshino river systems |
| Inland Wetlands | Kushiro Marsh, Sakata wetlands |
| Cultivated & Developed | Urban areas, agricultural plains |
step 3: identify ecosystem services at each location
Map which of the 19 ecosystem service flows your operations depend on at each location:
| Service | Relevance to Japan Operations |
|---|---|
| Water Abundance | Manufacturing, beverage production |
| Climate Stability | All operations, especially coastal |
| Raw Materials | Forestry, fisheries, agriculture inputs |
| Risk Resilience | Flood control, storm buffering |
step 4: connect to geographic units
Assign each location to its bioregion and ecoregion. This provides the reference system for ongoing disclosure and investment.
step 5: prioritize for action
Rank locations by:
- Materiality of dependency
- Current ecosystem condition
- Feasibility of investment
- Alignment with existing conservation programs
frequently asked questions
what if my operations are urban?
Urban areas are the "Cultivated & Developed" ecosystem stock. They still depend on ecosystem services — stormwater management, urban heat mitigation, air quality. Map the green infrastructure and watershed connections that serve your urban facilities.
how specific should locations be?
As specific as possible. "Japan" is not useful. "Taiheiyo Evergreen Forests ecoregion" is better. "Tone River watershed within Kanto region" is best. Specificity enables targeted investment.
what about supply chain locations outside Japan?
The same framework applies globally. Identify the bioregion and ecoregion for each supply chain location. Over 800 ecoregions are already represented in the ensurance protocol.
how does this connect to TNFD reporting?
Location mapping feeds directly into TNFD's Strategy and Risk Management pillars. Specific locations enable specific risk assessment and specific mitigation actions — which is what regulators and investors want to see.
