Kobotoke Sekisho (Kobotoke Checkpoint Ruins) is a significant historical site located in Hachioji, Tokyo, situated along the vital Koshu Kaido highway. Positioned near the Kobotoke Pass of Mt. Takao, which served as the border between Musashi and Sagami provinces, this site played a crucial role in regulating traffic during the Edo period. Today, it is designated as a National Historic Site, where the remains of the checkpoint are carefully preserved. The area is surrounded by lush nature, making it a popular destination for hikers and those wishing to see beautiful plum blossoms in the spring.
The history of this checkpoint dates back to the Sengoku (Warring States) period. It is believed to have been established by Hojo Uteru at the top of Kobotoke Pass during the Tensho era (1573–1592). Later, in 1580, the checkpoint was relocated to its current location in Komakino. During the Edo period, it functioned as a highly fortified checkpoint on the Koshu Kaido, strictly managing the passage of weapons and women to ensure security.
The checkpoint was managed by dedicated officials, typically a team of four guards. These officials were granted residences nearby and played a role in the local community. The checkpoint system was abolished nationwide following a government decree in 1869 (Meiji 2). In 1928 (Showa 3), the site was designated as a National Historic Site, and it remains a precious piece of history today.
The greatest attraction of the Kobotoke Sekisho Ruins is the stone structures that provide a tangible connection to the past. Visitors can see the "Tegata-ishi" (handprint stone), where travelers once placed their hands to verify their identity, and the "Tsukishi" (resting stone), where people placed their hands while waiting for inspection. These artifacts offer a vivid glimpse into the daily operations of an ancient checkpoint.
From historical records, one can also reconstruct the layout of the former checkpoint. It featured an East Gate and a West Gate, with a guard post situated to the north. The surrounding landscape, once regulated by bamboo fences (takeyari), allows visitors to imagine the strict traffic control of the era.
As an outdoor historical site, there are no specific opening hours. The area is particularly famous for its plum blossoms, making a visit in early spring highly recommended for those seeking beautiful floral scenery. Additionally, because it is part of a larger hiking network, you can enjoy the changing colors of the seasons throughout the year while walking through the natural environment.
The primary activity here is a contemplative walk through history. By observing the surviving stone artifacts, you can learn about the mechanisms of transportation and the strict regulations of the Edo-period highway system. Most visitors combine their visit with hiking or walking to fully immerse themselves in the natural and historical atmosphere.
The ruins are located in a nature-rich area leading toward the famous Mt. Takao. Beyond the historical sightseeing, the surrounding trails are excellent for nature lovers. Hachioji also boasts many other historical sites and cultural assets, which can be explored as part of a deeper cultural journey through the region.
