We have summarized what we have studied up to now into one proposal using the house and the site of our previous base in Keihoku.

This proposal is including the thatched roof as a system that has created the natural cycle from the forest to the sea, the cycle of nature, people’s activities, people’s connections, and the local landscape, and the attempt to apply traditional wisdom in the modern age through scientific research on the effects of microbiological environment and hypersonic sound effect on people’s physical and mental health.

The site includes a cypress forest, thatch field, bamboo forest, bracken field, small reservoirs, and fields, and is rich in wild vegetables in spring and fruits in fall.
The owner has been absent, and the fields and land have been neglected and in disrepair for many years. Since 2023, we started to create an edible biotope and some buckwheat fields on the site while regenerating the environment surroundings and a garden next to the house.

The biotope was created by drawing water from two small reservoirs in the hills behind the house and creating a waterway, where rice plants, water bamboo, watercress, buckwheat, tomatoes, bell peppers, taros, melons, watermelons, and other edible plants and seasonal flower seeds were planted. The area became a habitat for many living creatures such as newts, frogs, dragonflies, and grasshoppers.

Although no pesticides or fertilizers were used, we were still able to reap a large and plentiful harvest.
In this area, there is severe animal damage caused by deer and wild boars, and the fields and rice paddies around fields and rice fields are fenced off because of the damage they cause. However, this biotope has yet to be damaged by animals, even without a fence due to water running which makes buffer zone.

In addition, hypersonic sound effect is emitted from the water flowing from the mountains, which helps to boost people’s immunity, reduce stress, and improve mental illness.

This biotope was created as a model to make use of a wasteland and to make the most of our past research. We would like to make use of such a good cycle for both people and nature in future national land planning, urban planning, regional planning, landscape design, and architectural design.

In the future, we plan to use the timber, bamboo, thatch, soil, and other materials harvested here to create thatched tea houses and healthy housing, as well as mental and physical health programs and environmental education programs that make use of the forest.
