Miyawaki Forest Plantation
A Miyawaki forest is a dense, multi-layered forest of native species planted close together on prepared soil, a method developed by Japanese botanist Akira Miyawaki. It suits small urban plots, campuses and industrial sites. Grow Billion Trees prepares the site, plants and cares for the forest until it can sustain itself.
The Miyawaki method
- Developed by Japanese botanist Akira Miyawaki from the 1970s.
- Uses only species native to the area, in several canopy layers.
- Saplings are planted densely, commonly around three per square metre, on enriched soil.
- Needs watering and weeding for the first two to three years, after which it largely sustains itself.

What it changes
- Nature: Dense native habitat for birds, insects and soil life in a small footprint.
- Microclimate: Shade, cooler surroundings and better rainwater soak-in.
- Communities: A green space employees and neighbours can see and use.
- Companies: A visible, trackable forest for CSR and ESG reporting.
How it works
- Site survey and soil test
- Choose native species in canopy layers
- Soil preparation and dense planting
- Two to three years of care
- Handover and ongoing tracking
Frequently asked questions
What is a Miyawaki forest?
A dense, multi-layered forest of native species planted close together on prepared soil, a method developed by botanist Akira Miyawaki.
How much land do we need?
Miyawaki forests suit small plots; we size the forest to the space you have, from campus corners to larger sites.
How long does it need care?
Usually two to three years of watering and weeding, after which it largely sustains itself.
Which species are planted?
Only species native to the area, chosen for each canopy layer.
Can employees join the planting?
Yes, many companies plant their Miyawaki forest as an employee planting day.
