Many sections of the Nakasendo are sheltered by the branches of tall trees. Japanese cypress, cedar, and pine trees have grown high over the trail, and their spreading branches protect travelers from rain, wind, and strong sunlight.
For example, on the most popular route from Magome to Tsumago, approximately 50% of the trail passes beneath the trees. In light rain, there are even sections where you may be able to walk without an umbrella.
During the hottest part of summer, temperatures can exceed 35°C (95°F). Even then, walking along the shaded trail can make you feel as though the trees are protecting you from the heat.
Some people may not enjoy hiking in the rain. However, light rain can add a special atmosphere to the journey from Magome to Tsumago.
Walking along the rain-darkened stone paths and through the wet forest, you can imagine the travelers who walked the same route during the Edo period.
This is another special way to experience the Nakasendo.
