What is Oyama Sando? | An Autumn Foliage Spot Where Meiji History Lives
Oyama Sando is an approach leading to the grave site of Field Marshal Iwao Oyama (大山巌), a military general who distinguished himself in the Russo-Japanese War, and his family members. This area was recognized as a Japan Heritage site in Heisei 30 (2018) as “The Future Envisioned by Meiji Nobility: A Tale of Nasuno-gaihara Reclamation Romance,” making it an important historical spot that conveys the spirit of Meiji-era land reclamation to the present day.
The Connection Between Field Marshal Oyama Iwao and Nasuno-gaihara
Iwao Oyama, a former samurai of the Satsuma clan and a duke, owned vast farmlands of 273 cho-bu (approximately 271 hectares) in the Nishinasuno district. He was deeply involved in the land reclamation project of Nasuno-gaihara and built a villa in this area, making a significant contribution to regional development.
After Oyama’s death, the approach was improved by Sanzo Yamamoto, a technical officer of the Imperial Household Ministry. With the Ohtawara Highway as the dividing line, cypress trees were planted north of the highway, while Japanese maple trees were planted to the south—a carefully planned design.
A Brilliant Red Maple Tunnel | The Charm of Autumn Foliage
The greatest attraction of Oyama Sando is, without doubt, the brilliant red maple tunnel that appears during the autumn foliage season. The approximately 100-year-old Japanese maple trees planted on both sides of the approximately 200-meter-long approach create a vividly colored arcade when they reach their peak season.
Characteristics of the Autumn Foliage
- Tree Type: Japanese Maple (Iromomiiji)
- Number of Trees: Approximately 80
- Tree Age: Approximately 100 years and above
- Length of Approach: Approximately 200 meters
- Landscape Feature: The entire approach turns brilliant red, forming a tunnel-like maple arcade
The approach extends in a straight line, and as the branches of the maples intersect overhead, a natural tunnel is formed. On clear days, sunlight passes through the maple leaves, creating a fantastical scene where red light illuminates the approach.
Beautiful New Greenery Season as Well
Oyama Sando is beautiful not only during autumn foliage but also during spring and early summer when fresh new leaves appear. The vibrant green of young leaves covers the approach, offering a refreshing atmosphere different from the autumn colors. With its changing expressions throughout the seasons, this approach is worth visiting year-round.
