The greenhouse project process in Japan — scope to supplier offers
Japanese greenhouse projects carry high structural, labour and automation costs. Typhoon-rated frames and foundations are essential across much of the country; northern prefectures add snow and heating, while southern sites add cooling and dehumidification. Limited land and labour favour compact high-output systems with automation, but grid and energy cost must support the chosen technology.
Direct answer
A commercial greenhouse project in Japan runs through six stages: define scope and season, set the local cost band, build the CAPEX estimate, run the readiness check, submit one written specification through a private RFQ, then compare landed offers on a like-for-like basis. Every brief is reviewed by a sourcing specialist before any supplier is approached — nothing is published and no supplier contacts you directly.
The six stages
1. Define the project scope
Fix the site location in Japan, the cropped area, the target crop and the production season. Locally, that usually means tomato, strawberry, leafy greens, herbs, cucumber, pepper, propagation and premium fruit or nursery crops for domestic retail.. Scope decides the technology level long before any supplier is involved.
2. Set the local cost band
Read the published Japan installed bands per m² and per hectare, and the operating cost that goes with each technology level. These are planning bands, never a quotation.
Open this step3. Build the CAPEX estimate
Run the country builder for your area, structure level and site condition. Site works and connections in Japan typically add the uplift described below, on top of the hardware band.
Open this step4. Check project readiness
Run the builder readiness check. It confirms whether the scope, water, power, budget and decision path are defined enough for suppliers to price the same thing, and names exactly what is still missing.
Open this step5. Submit one written specification
Submit a private project brief. A sourcing specialist reviews it, converts it into one written specification and approaches qualified suppliers manually. Supplier identities stay private and your contact details are never released before review.
Open this step6. Compare offers on one basis
Compare returned offers on a landed, like-for-like basis for Japan — the same structure, climate, irrigation and installation scope in every offer. That is the first number a lender or board will work with.
What decides the budget in Japan
Humid temperate to subtropical, with typhoon wind, heavy rain, regional snow loading, hot humid summers and cool winters.
Typhoon and snow design
Prefecture wind and snow classes determine steel weight, anchoring, glazing and foundation cost before climate equipment is considered.
Heat and humidity
Summer cooling and dehumidification compete with winter heating; the balance changes markedly between Hokkaido, Honshu and Kyushu.
Land and site shape
Small or irregular sites increase civil works, internal logistics and cost per square metre.
Labour and automation
High labour cost makes seeding, transplanting, harvesting support, grading and internal transport important capital lines.
Energy and grid
Electricity and fuel tariffs, connection capacity and resilience planning determine whether heat pumps and LED are viable.
Site works and exclusions
Add 18–35% for structural engineering, permits, reinforced foundations, drainage, utility upgrades, water treatment and access on constrained sites. Land, packhouse and cold storage are separate.
Financing routes
Japanese projects commonly combine bank or agricultural-cooperative lending, equipment leasing and eligible national or prefectural smart-agriculture and energy programmes. SeedMatchGroup is not a lender; independent finance review requires a defined scope and supplier-backed pricing.
Build your Japan estimate
For Japan, enter the prefecture's typhoon wind and snow class, summer humidity, winter design temperature and utility tariffs. The climate result should reflect the regional balance between cooling, dehumidification and heating.

Planning bands only — not a quotation and not a SeedMatchGroup price. Committed pricing comes from qualified suppliers responding to one written specification, reviewed by a sourcing specialist before any supplier is approached.

Project process questions
How does a greenhouse project in Japan move from idea to supplier offers?
In six stages: define the scope and season, set the local cost band, build a CAPEX estimate, run the readiness check, submit one written specification through a private RFQ, and compare offers on a like-for-like landed basis. A sourcing specialist reviews the brief before any supplier is approached.
What budget should a project in Japan plan for?
At the published planning bands, a high-tech glass / rigid-clad costs roughly USD 220–480 per m² installed, which is about USD 2.2M – USD 4.8M for one hectare before site works and land. Add 18–35% for structural engineering, permits, reinforced foundations, drainage, utility upgrades, water treatment and access on constrained sites. Land, packhouse and cold storage are separate.
What usually delays a project in Japan?
Undefined water source and quality, an unconfirmed power connection, and a scope that changes after suppliers have quoted. The readiness check exists to surface those before the RFQ, not after.
Does SeedMatchGroup build or finance the project?
No. SeedMatchGroup is not an EPC contractor, engineering firm or lender. It runs a human-reviewed sourcing process: one written specification, qualified suppliers approached manually, and comparable offers returned to you. Japanese projects commonly combine bank or agricultural-cooperative lending, equipment leasing and eligible national or prefectural smart-agriculture and energy programmes. SeedMatchGroup is not a lender; independent finance review requires a defined scope and supplier-backed pricing.
What project size is worth this process?
SeedMatchGroup works on commercial agricultural projects from roughly USD 250,000 upwards. Smaller builds are better served by a local supplier directly.
