Four-Step Process of Planting a Miyawaki Forest:

1. Preparation and Analysis

• Site Analysis: Begin with a thorough analysis of the site, considering factors like soil type, water availability, and sunlight exposure. This analysis guides the selection of native plant species best suited for the location.
• Soil Preparation: Clear the area of weeds and debris. Loosen the soil by tilling and amend it with organic compost to enhance fertility and moisture retention.

2. Plant Selection and Planting

• Plant Selection: Choose native plant species that are fast-growing, drought-resistant, and indigenous to the region. Diversity is crucial to mimic natural forests and promote ecological balance.
• Planting Technique: Dig pits or trenches for planting saplings, ensuring each has enough space to grow. Plant at a high density, typically 3 to 5 times denser than traditional forests.

3. Care and Maintenance

• Watering: Initially, saplings need regular watering to establish their roots. Once established, they require less frequent watering, but regular monitoring remains essential.

4. Monitoring and Growth

• Regular Maintenance: Perform regular weeding, pruning, and pest control during the initial years. Miyawaki forests become self-sustainable as they mature but still require occasional maintenance.
• Monitoring: Keep track of the forest's growth and health, monitoring for signs of stress, disease, or pest infestations and taking timely action when needed.

Four Layers of a Miyawaki Forest

The Miyawaki method emphasizes creating a multi-layered forest that mimics natural forests to achieve rapid growth and high biodiversity. Here are the four layers typically found in a Miyawaki forest:

• Canopy Layer: This topmost layer consists of tall trees that provide the canopy. These trees are usually fast-growing species that can reach heights of 15 to 30 meters or more. They offer shade and protection to the layers below.
• Tree Layer: Beneath the Canopy layer is the tree layer, consisting of smaller trees and larger shrubs. These plants help fill in the gaps between the taller trees, contributing to the dense foliage that characterizes a mature forest.
• Shrub Layer: Below the canopy, the shrub layer includes smaller shrubs and bushes that provide additional structure and diversity to the forest. These plants play a vital role in attracting pollinators and providing habitat for various wildlife.
• Ground Layer: The lowest layer is the ground layer, comprising ground covers, ferns, and herbaceous plants. These plants help to retain moisture, suppress weeds, and protect the soil. They also contribute to the overall biodiversity by providing habitat for insects and microorganisms.

Each layer in a Miyawaki forest serves a unique purpose and contributes to the forest's resilience, biodiversity, and ecological functionality.

Advantages of Miyawaki Forest

Rapid Growth and Dense Green Cover

The Miyawaki method ensures that trees grow up to ten times faster than conventional plantations, creating a dense, multi-layered forest within a few years. By implementing this approach, Castle Ships accelerates the development of green spaces in port areas, transforming barren land into a thriving ecosystem. This rapid growth enhances environmental sustainability, ensuring quicker carbon absorption and improved air quality.

Enhanced Biodiversity and Ecological Balance

By planting only native tree species, the Miyawaki forest fosters a self-sustaining, biodiverse habitat that supports various birds, insects, and wildlife. Castle Ships' initiative contributes to restoring the natural balance of the ecosystem, making port areas more resilient to climate change. This diverse green cover strengthens soil health, prevents erosion, and nurtures a thriving habitat that benefits both nature and local communities.

Carbon Sequestration and Climate Change Mitigation

The dense plantation acts as a powerful carbon sink, absorbing a significant amount of CO₂ emissions, which is crucial for reducing the environmental footprint of industrial and maritime activities. Castle Ships' initiative aligns with global sustainability goals by actively combating climate change, helping to lower greenhouse gas levels in the atmosphere. This not only benefits the company’s environmental responsibility efforts but also contributes to global carbon neutrality targets.

Improved Air Quality in Port Areas

Ports and industrial zones often suffer from high levels of pollution due to emissions from ships, transport vehicles, and logistics operations. Castle Ships' Miyawaki forest helps purify the air by filtering pollutants, releasing oxygen, and reducing airborne particulate matter. The lush green canopy acts as a natural shield, improving air quality and creating a healthier environment for port workers, local communities, and marine ecosystems.

Minimal Maintenance and Long-Term Sustainability

Unlike conventional plantations, Miyawaki forests require little to no maintenance after the first three years, as native species adapt to their environment and form a self-sustaining ecosystem. Castle Ships' initiative ensures long-term environmental benefits with minimal human intervention, making it an efficient and cost-effective green solution. Over time, these forests grow naturally without the need for artificial irrigation or fertilizers, ensuring their sustainability for future generations.

Temperature Regulation and Noise Reduction

The dense foliage of a Miyawaki forest plays a crucial role in reducing temperatures in urban and industrial areas by providing natural cooling effects. By planting this forest near port zones, Castle Ships helps create a more comfortable microclimate, reducing the heat island effect often caused by concrete and metal surfaces. Additionally, the thick green cover acts as a sound barrier, minimizing noise pollution from port activities, and making the surroundings more peaceful and livable.

Activities During Tree Plantation

During the Castle Ships tree plantation initiative, employees, along with Grow Billion Trees (GBT) volunteers, actively participated in creating a thriving Miyawaki forest. The event commenced with a worship ritual, symbolizing respect for nature and a commitment to environmental stewardship. With the site prepared beforehand, the plantation activity focused on efficiently planting saplings in pre-dug pits, ensuring proper spacing and soil support for healthy growth. Participants carefully placed each sapling, fostering a sense of environmental responsibility and teamwork. Once planted, the young trees were watered to provide them with the necessary hydration for a strong start. This collaborative effort not only contributed to greening the port area but also reinforced Castle Ships’ commitment to sustainability, biodiversity, and climate action.

Tree Plantation Purpose

1. SDG 3: Good Health and Well-being

The Miyawaki forest enhances air quality by absorbing pollutants and releasing oxygen, contributing to a healthier environment for port workers and nearby communities. Reduced air pollution leads to lower respiratory illnesses and overall improved well-being. The green spaces also create a calming effect, reducing stress and promoting mental health. By fostering a cleaner, greener atmosphere, Castle Ships actively supports a healthier future for all.

2. SDG 6: Clean Water and Sanitation

Dense forests improve groundwater retention by preventing excessive runoff and allowing rainwater to seep into the soil, replenishing underground water tables. The Miyawaki forest helps in natural water filtration, ensuring better water quality in the long run. Additionally, the trees play a role in preventing soil erosion, which protects nearby water bodies from sedimentation and pollution. This initiative aligns with Castle Ships’ commitment to preserving natural resources.

3. SDG 7: Affordable and Clean Energy

While forests may not directly generate energy, Miyawaki plantations contribute to cleaner environments that support sustainable energy initiatives. By mitigating heat in industrial zones, these forests reduce the need for excessive cooling and energy consumption. The reduction in greenhouse gas emissions indirectly supports a shift towards cleaner energy sources. This initiative complements broader environmental strategies for a sustainable energy future.
