Why Tea Gardens Need DX Now

Japan’s tea industry faces a dual crisis of aging and successor shortages. The average age of core agricultural workers exceeds 67 years, and the number of tea farms decreases annually. While cultivation area per farm is expanding, labor shortages prevent adequate management, leading to increased harvest losses and quality deterioration.

Furthermore, unstable harvest timing due to climate change has become serious. Spring temperature extremes and frost damage cause first-flush sprouting to occur earlier or later than usual, disrupting labor allocation plans and increasing risks of missing optimal picking windows and quality decline.

For OEM contracts and export markets, off-specification or highly variable raw materials are unacceptable, making “stable quality and stable supply” more important than ever.

The key to solving these challenges is Digital Transformation (DX):

• Visualize growth conditions with drones and detect fertilizer irregularities and disease signs early through vegetation indices (NDVI)
• Monitor soil moisture and temperature-humidity in real-time with IoT sensors, automatically controlling shading and irrigation timing
• AI analysis for harvest timing determination, concentrating labor resources effectively

Combining these mechanisms creates “smart tea gardens” that efficiently produce high-quality tea with limited manpower.

The Ministry of Agriculture, Forestry and Fisheries promotes data-driven agriculture through the “Midori Strategy,” and prefectures are accelerating drone introduction subsidies, sensor installation support, and smart agriculture training. With strengthened regional cooperation like “Tea Industry DX Promotion Councils” from 2025 onward, now is the optimal time for implementation.

Drone-Based Growth Visualization

Drones are among the most readily demonstrable DX technologies for tea gardens. Scanning tea gardens from above “visualizes” growth conditions across wide areas in short time frames—previously difficult with traditional methods. Growth irregularities and disease signs easily missed during foot inspections become detectable as data.

Multispectral Cameras for Leaf Color and Disease Detection

Multispectral cameras mounted on drones capture light wavelengths invisible to the naked eye for analysis:

• NDVI (Normalized Difference Vegetation Index) quantifies leaf color and growth status numerically
• Early detection of growth irregularities and stress from excess or insufficient fertilizer
• AI extraction of early disease and pest outbreak signs

This enables pinpoint application of pesticides and fertilizer only where needed, reducing input costs while lowering environmental impact. Demonstration cases show fertilizer reductions of 10-15% through drone utilization.

Harvest Timing Determination

Drone imaging data, combined with AI analysis, enables scientific prediction of optimal picking periods:

• Integrating leaf color changes, solar radiation, and temperature data to model growth curves
• Calculating timing when umami components (L-theanine) peak
• Scheduling concentrated worker deployment at peak times

This prevents quality deterioration from early or late harvesting while maximizing yield. Even labor-short tea gardens can allocate workforce efficiently, ultimately leading to improved profitability.

IoT Sensor-Based Quality Management

Tea quality stability depends heavily on environmental management before and after harvest. IoT sensors excel here. Continuously collecting data from sensors installed in fields and factories, viewable real-time on smartphones or PCs, transforms cultivation management from “intuition and experience” to data-driven decision making.

Soil and Moisture Sensors

L-theanine and amino acid content that determine tea umami are strongly influenced by soil moisture and nutrient balance, along with shade cultivation management. IoT sensor implementation enables:

• Real-time monitoring of soil moisture, EC values (electrical conductivity), and nutrient concentrations
• Automatic irrigation control linked with rainfall data
• Automated shade opening/closing coordinated with temperature-humidity sensors

This constant optimization of cultivation environment enables high-quality first-flush tea with pronounced sweetness and aroma. Demonstration farm cases report L-theanine content increases of 10-15% through optimized shade timing adjustments.

Data Integration from Harvest Through Shipment

Post-harvest management is equally critical for high-quality tea production:

• Monitor crude tea storage environment with temperature-humidity loggers, preventing oxidation and flavor deterioration
• Centrally manage production history and temperature-humidity data by lot on cloud platforms
• Automatically generate specification sheets and COA (Certificates of Analysis) at shipment

This achieves high-precision traceability (production history tracking) required by OEM partners and export destinations. Recent years have seen stricter food safety certification requirements (ISO22000, FSSC22000) and lot management demands in overseas markets, making data integration increasingly essential for export business.

Implementation Cases and Results

DX is not theoretical—it’s already delivering results in tea-producing regions. Tea cooperatives in Kagoshima and Shizuoka prefectures are increasingly adopting drone × AI analysis yield prediction systems, reporting effects including:

• Improved Shipment Planning Accuracy
  Analyzing growth conditions from drone imagery to predict yields in advance. This enables pre-adjustment of tea factory operations and personnel allocation, building systems that smoothly handle even peak seasons.
• Reduced Quality Variation
  Early detection and correction of fertilizer irregularities and diseases improves tea leaf color, aroma, and taste stability. For export-grade tea leaves, cases show over 20% reduction in off-specification loss rates compared to previous methods.
• Enhanced Trust in Export OEM Contracts
  Ability to consistently issue COA (Certificates of Analysis) and specification sheets on a per-lot basis strengthens buyer confidence. This results in increased contract unit prices and acquisition of new trading partners.

For example, one Kagoshima tea cooperative achieved approximately 90% yield prediction accuracy within two years of drone implementation, virtually eliminating shipment adjustment errors. In Shizuoka, shade management linked with IoT sensors increased L-theanine content 15% year-over-year and improved award competition placement rates, contributing to brand strength enhancement.

Implementation Steps and Cost Considerations

When hearing “DX implementation,” many worry “Won’t this require huge investment?” However, recent years have seen rental and sharing services making technology accessible even for small-scale farmers, enabling phased adoption.

Small-Scale Farm Steps

Large-Scale Tea Garden Steps

For large operations, purchasing proprietary drones and multispectral cameras while integrating AI analysis with cloud management systems proves more advantageous long-term. Building in-house imaging and analysis capabilities expands data utilization scope, enabling more precise cultivation planning.

Cost Overview and Recovery Period

Generally, expect:

• Drone complete set: ¥300,000–1,000,000
• Multispectral camera: ¥500,000–1,500,000
• IoT sensors and cloud service fees: From tens of thousands of yen annually

However, utilizing Ministry of Agriculture Smart Agriculture Demonstration Projects and prefectural subsidies can cover 1/2 to 2/3 of implementation costs, significantly reducing actual burden.

ROI (Return on Investment), combining:

• Waste reduction through improved yield prediction accuracy
• Agricultural chemical cost reduction through efficient pest and disease control
• Labor cost compression through workforce efficiency

typically achieves investment recovery within 2-3 years on average. Some cases recovered within under one year through increased export OEM contract unit prices.

Future Outlook: Smart Tea Gardens Becoming the Norm

Tea garden DX is not a temporary trend but will become the standard model going forward. With AI and robotics evolution, autonomous harvesting machines and harvest robots are already in demonstration trials, with future prospects for unmanned harvest operations at night or early morning. This will dramatically reduce farmer labor burden, offering fundamental solutions to labor shortage problems.
。

Additionally, from perspectives of globally prominent ESG investment and carbon credit trading, smart agriculture earns high evaluation from companies and investors emphasizing environmental impact reduction and sustainability.

Specifically:

• Optimizing fertilizer and pesticide amounts to reduce environmental impact
• Visualizing CO₂ emissions through data-driven energy efficiency management
• Obtaining carbon neutral certification and sustainable certifications

These initiatives lead to enhanced brand value and entry into high-value-added markets.

Furthermore, the future envisions completely traceable tea becoming standard. Consumers will simply scan QR codes with smartphones to confirm:

• Which tea garden grew the leaves
• What environment cultivated them and how they were processed
• COA (Certificate of Analysis) and pesticide residue test results

This will increase consumer confidence and purchasing motivation, accelerating premium tea market expansion.
