The native woodlands are foundational for all other Japanese gardens. They have been revered for thousands of years as part of Shinto. They are geologically, ecologically, historically, culturally and economically important. The previous posts in this series have reviewed the cultural insights and history of the Japanese gardens. This is part three of a six part series on Japanese gardens. The purpose of this presentation is to focus on the value and management of the forests. Can these be applied to care of woodlands in Florida and the East Coast of the USA?

There are three garden types in Japan that include woodlands, food production gardens, and the classic traditional gardens. Here is a brief overview of the forests in the wilderness of Japan.

The feature image is typical of the countryside viewed from the cable car on the way to Mt. Fuji. It is mountainous and covered with a forest of predominantly gymnosperm trees.

The history of Japan has significantly altered the natural woodlands of Honshu. The wilderness is not as natural as expected. 75% of Japan is densely forested. Forty percent’ was planted by people. There is a deep and protracted use of the woodlands for lumbering. The giant shrines with statues of the Buddha are made of cedar and cypress harvested from the wilderness. Historically all of the major buildings and residences were built from local wood. Until the twentieth century no other materials were used.

Deforestation Events

The forests were depleted of wood from three major events. There were two major event periods of construction which consumed whole mountains of wood. The first was during the castle shogun period the 1700’s. These included many square miles of defensive castles and associated residences for soldiers, civilians and commerce. Simultaneously, the residences and temples of the Buddhists were constructed. The second period was during the Edo and the Mejie eras. Edo construction focused on the new capital now called Tokyo. The third and period was the combination of the 1850’s through 1950. The forests were severely depleted as never before. This third period included deforestation for construction and devastation as a result of war.

Deforestation has an impact on the geology and ecology. Without the tree roots to hold the soil, earthquakes, floods, land slides with mud and rocks ensued. To restrain the soil trees were aggressively replanted with cedar and cypress with very little diversity. In 1954 The public was incentivized to plant even more. That incentive indirectly increased further deforestation of diverse native tree angiosperm hardwood species like the maple.

This had a further modern impact of construction lumber. Its value depends on good management of the trees. To grow straight, tall and knot free, the limbs need to be trimmed. To allow sufficient light and access to the trees the forest needs thinning. To be accessible to harvest, the slopes of the hills must be within the capacity of the power equipment. This is demanding work requiring a skilled and able labor force. The population of Japan is aging. The wage rate compared to other countries is relatively high There are insufficient foresters to develop an industrial timber crop. As a result of this, the trees are of questionable value. The monocultural nature of the crop also makes the forest susceptible to pests and diseases. The understory is sparse and not diverse. The wildlife is severely limited. To compete with imported lumber the method of management needs to be rethought.

Spiritual Value of Old Trees as Seen in Art

Shinto regard of trees and forests is foundational. Recall that there has been a long veneration of trees which we described in the last posting. This value dates back thousands of years. They are assigned individual and group value as Kami spirits.

In Japan, old trees are venerated for their resilience, strength and power. Allegorically, they offer a bridge to the past. Both of these concepts are essential to the concept of Shinto. Blossoming trees are also highly regarded. Most notably are the spring blooms of the weeping cherry and plum trees. Autumnal trees with seasonal chromatic change in the leaves offer even more inspiration for artists.

Buildings for the Community Revering Forested Trees

The size of the remaining wooden buildings speak volumes about the mass of lumber needed for the temples, castles and residences of ancient Japan. The Great Buddha Hall of Tōdai-ji in Nara Japan is the world’s largest wooden building. It houses the largest cast bronze seated Buddha statue. It is only one of the few remaining giant Buddha halls. These images of notable wood structures do not truly capture their great size. Maintenance of these halls, palaces and castles is constant, expensive, and requires expert craftsmen and are paid for by donations. The remaining buildings are a small fraction of all of the original buildings that once existed.

Private Wooden Buildings

The Gion district in Kyoto and the Yasaka-no To Pagoda has a high concentration of traditional wooden machiya merchant houses. This area was established 1300 years ago. Many of these wooden buildings date back to the Meiji period more than 150 years ago. Most of the original buildings were destroyed in the fire of 1865. In Kyoto those which were rebuilt were not destroyed in WW II. There were wooden structures like these in Tokyo. They were the norm and as you would expect, during WW II most of them burned. Only a few pockets of these remain. They were replaced with modern buildings made of steel reinforced concrete and glass.

Trees by the numbers

The foliage distribution strongly overlaps the mountainous areas which we described in the first of this series on Japan. To better appreciate the distribution of trees in Japan, the following illustrations will show the varieties and locations in the island group. This underscores the limited accessibility to manage the growth or to commercially harvest the wood.

Reforestation:

There is a strong response to the tree management in today’s Japan. The forests of Japan rank third in the world for percentage of forest covered land. Modern management techniques including diversification of species are being applied and the use of local lumber is increasing.

Japan is now making a concerted effort to reforest and rewild their woodlands. Although this is a public works project and is government sponsored/funded it depends on community part time and volunteer workforce. It includes incremental reforestation using a variant of the Montreal process. This successful process has been widely applied in many locations around the world. The dedication and discipline of the people of Japan have made this do-it-yourself (DIY) project an example that could be followed here in Florida.

CONCLUSION

Forests continue to play an important part in Japan both spiritually and economically. Hopefully we can learn that over deforestation and questionable management can result in unintended consequences. The reversal of the untoward results can be costly, labor intensive and time consuming.

In our next posting we will explore the productive gardens as farms in Japan. Later we will see the classic formal gardens
