Design and construction of gardens, landscaping, and exterior work


Creating a small satoyama

Hayashi Garden Design Office designs and builds gardens inspired by satoyama, wooded areas where birds, insects and other creatures of the natural world live in harmony. Our approach to gardening starts with cultivating the soil. It's about making the most of nature and plants. The soil is the interface between nature and man. We start by cultivating the soil for the long term to create a garden that is suited to the land and the seasons, using as few pestisides as possible.
To create a garden in line with your lifestyle. We don't just add greenery to your garden, we choose species that are in keeping with your lifestyle. We maintain the garden for the long term through maintenance. The pruning of mature plants is an important part of their life. The pruned branches are turned into powder and returned to the soil.
Our high level of proposal and workmanship is due to our knowledge of the characteristics of plants and materials and our constant ambition to improve our techniques and skills. Our Chairman, Mr. Hayashi, has been designing and constructing gardens for over 40 years, working with his apprentices to design and construct their own gardens. The method of correcting and redesigning the plans on site allows us to follow the construction of the site and to be flexible to any changes or additions requested by the client.
No two gardens are ever the same. This is because we have the skills and know-how to use materials that have been refined by time, such as reusing stones that have existed on the client's land for a long time, ancient stones quarried 200 years ago, driftwood and old roof tiles. Add to this the growth of plants and you have a one-of-a-kind garden creation.

Chairman HAYASHI YOSHIJI’s message



There are two designs for creating a garden.

The first is a desk/paper design. The architect will design the overall plan of the garden. The other is the design of the actual construction. The second is the constructional design, which is carried out in the garden by the gardener, who works with the actual objects in the garden, considering the design and fit of each part of the garden. It is the combination of these two aspects of design that makes a good garden. The better both the designer and the gardener know the properties of the materials, the better the garden will be. The following three elements are also essential in creating a good garden.


Divide the whole site into rooms

If you are going to build a house, you should plan the whole site including the garden when you plan the building. How will you arrange the garden on this site? We will design the building, the gate wall, the car park, the bicycle parking lot, the storage room, the drying room, etc. as a room of the outside room, considering the usability and the line of flow.


The three lines of sight

(1) The view from inside the room and garden
(2) The view from the exterior where the whole building can be seen
(3) The view from the street and the sky.
It is important that the garden appears to have vertical depth rather than being spread out horizontally when viewed from the building. A sense of unity between the building, exterior and planting is also an important element.



The importance of soil

In a wooded area, there is always a layer of fallen leaves and the soil underneath is soft and fluffy. This is the ideal condition called aggregate structure for the growth of plants. Soil particles form small grains, which are then mixed together to form large and small clods, creating a well-balanced mixture with plenty of gaps. This type of soil has excellent drainage and water holding capacity and is rich in micro-organisms that are useful for plant growth. In a plant garden, this kind of soil preparation is fundamental to the management of a healthy garden that is resistant to pests and diseases. After the garden is completed, we do not throw away fallen leaves and pruned branches, but cut them into small pieces and spread them on the garden as chips, continuing to maintain the garden in a way that reproduces the original natural cycle as much as possible.


Creating a garden is about creating soil

"Live soil purifies the air, even if there are no trees. We start by cultivating the soil before we build a garden, which allows air to enter the soil and creates an environment in which insects and worms can breathe. We then spread organic fertilisers such as prunings, bamboo, charcoal, peat moss and fallen leaves to encourage micro-organisms, fungi and enzymes to flourish. The matured manure enriches the soil with humus, which provides nutrients for the plants. If a terrace or other facility is to be built, the soil around it and in other areas should be tilled after the stable shape has been constructed.


Creating a one-of-a-kind garden using old materials

A quaint garden that looks good from the moment it is created. The reason for this is in the materials. Not only do we use the old stones and driftwood that are stocked in our materials yard, but we also use the fences, stones and trees that always exist in our clients' gardens. By using materials that have been around for a long time, we not only add to the beauty of the garden, but we also take care of the environment.



Stones (fences, stone walls, earth retaining walls, bridges, paving stones, scrap wood, etc.)
Wood (cuttings, thinned wood, driftwood, dead wood, formwork wood, windfall wood, etc.)
Vine collection (weeping bamboos, bush clover, Japanese apricot branches, garden bamboos)
Leftover materials from material stores (fragments, bricks, stones, concrete products)
Old tiles


Creating space with leftover materials

Using materials left over from the removal of the original structure, as well as surplus or leftover materials, we can create display areas such as stands, shelves etc. throughout the garden. This is a cost-effective way to improve the usability and appearance of your garden.


Plant breeding, handmade gardens

In addition to buying trees, one of the pleasures of a home-made garden is the opportunity to propagate plants by sowing seeds, taking cuttings, dividing plants, layering and exchanging seeds with neighbours and acquaintances. Sometimes birds carry seeds and unexpected plants grow. Observe your garden and look out for little surprises. It is also a good idea to keep one or two of the older, larger trees that previously existed in the garden, to make it look more calm.


Take the time to grow from seed or saplings

To get closer to nature and enjoy a seasonal garden, try planting deciduous trees and other fruit trees. Deciduous trees give a greater sense of season than evergreen trees. By taking advantage of their characteristics and physiology, and by considering the composition of the garden (sun and shade trees) (tall trees, medium trees and shrubs), you will be able to create a garden with depth and taste. Deciduous trees play an important role not only in the garden landscape but also in the living environment.

Evergreen and Deciduous Trees

The ratio of evergreen to deciduous trees in a normal garden is 6:4 or 7:3. In our specialty, the mixed tree garden, the ratio is reversed, with more deciduous trees.

    Characteristics of evergreen trees

    Evergreens are a year-round blindfold, as they never drop their leaves and remain green in winter. They should be placed at the back of the garden to create a bosom.

  • Plants

    Characteristics of deciduous trees

    The variety of flowers, fruits and foliage gives a sense of the seasons. They should be placed at the front of the garden to give it depth. In summer, they provide shade and help to reduce the temperature of the living environment if they are well grown, and create a breezy atmosphere if they are kept see through. In winter, when the leaves have fallen, it is brighter and warmer in the sun.


Making the most of nature, making the most of plants

We think about a garden that is suitable for the land and the seasons, starting with the long-term preparation of the soil, using as few pesticides as possible. Not only will we design and construct the garden as only we can, but after the garden is completed, we will carefully prune the trees, not only to maintain the landscape, but also to ensure the health of the trees. Our representative, Hayashi, who is an instructor at various schools, is also available to provide guidance on how to manage your garden if you wish.

Tree pruning

We do not focus too much on individual trees, but try to prune them as a whole to create a garden. The natural shape of a tree, with little or no pruning, shows the tree in its natural state, with its branches spreading out and looking beautiful. We prune the minimum number of branches as necessary, with the intention of keeping the tree healthy and "helping the plant".

Pruning branches are turned into powder and returned to the soil

The soil in a wooded area is covered with fallen leaves, rich in nutrients and moisture, without any special maintenance. We don't plough our gardens all year round like we do our fields, and many of us will clear away the fallen leaves, but we believe it is important for both plants and people to maintain the natural cycle. Powdering and spreading the pruned branches and enjoying the view of the fallen leaves instead of clearing them away will help to bring the garden environment closer to the natural cycle of a woodland.


A fluffy soil, rich in micro-organisms and nutrients

We produce and sell compost made from the natural fermentation of our pruned branches and leaves, as well as bamboo powder, as a way for individuals to revive the woodland cycle in their gardens, and to help keep the environment free from waste.

Pruning branch compost “For the soil of the future”

The ground in a thicket is covered with humus from branches and fallen leaves, which means that weeds rarely grow and the soil is fluffy and rich in micro-organisms and nutrients. “For the soil of the future” is an original compost made by reproducing the circulation of a thicket, using the thicket as a model. It is made from pruned branches and is naturally fermented without heat. It can be used for a wide range of purposes from home gardens to flower beds and soil improvement. It can also be used for planting seedlings, seed beds and ground covers. Tomatoes and fruit will become sweeter with increased sugar content.

Applications: Soil improvement, plant growth promotion, moisture retention, weed control, fruit trees, flower beds, fields, seedlings, seeds.

Bamboo powder with live lactic acid bacteria

Soil is mostly composed of carbon, hydrogen and oxygen. Bamboo contains a lot of carbon, and by spreading bamboo powder on the surface of the soil, it gives carbon to the soil and enriches the thin soil. In addition, microorganisms, such as live lactic acid bacteria, which are often hidden in bamboo, will attract more microorganisms and activate the soil. The action of microorganisms makes the soil contain oxygen and creates a good environment for microorganisms.

Applications: Soil improvement/weed suppression/water retention/sprouting promotion

●Recycling pruned bamboo
●Lactic acid bacteria is alive.
