Guide
Tochimoto Sekisho is a National Historic Site located in Otaki, Chichibu City, Saitama Prefecture. It was a vital checkpoint on the Chichibu Okan (also known as the Koshu Ura Kaido), a major route crossing the Gansaka Pass that connected the Musashi and Kai provinces. During the Sengoku period, it was established by the legendary warlord Takeda Shingen as a strategic military outpost to prevent invasions from the Musashi region. Later, during the Edo period, its role shifted to monitoring travelers and controlling the movement of weapons and specific goods. Today, it stands as a significant historical site where visitors can feel the atmosphere of ancient Japan amidst the natural beauty of Chichibu.
The history of this site dates back to the Sengoku period. It began as a military defense point established by Takeda Shingen to guard against incursions. By the Edo period, the focus shifted to the "Ittetsu-ppo De-onna" policy, which involved strictly monitoring the transport of weapons and women. The area also played a role in overseeing local gold mines. In 1631, to strengthen security, various guard posts like the Aso Kabansho were established near the current Otaki area. The management of the checkpoint was a hereditary duty of the Omura family throughout the Edo period. While the original structures no longer stand, the site is officially designated as a National Historic Site, preserving the memory of this era.
At the Tochimoto Sekisho ruins, you can experience the topography of a former major highway hub. While the original buildings are gone, the surrounding landscape and educational materials allow you to visualize the tension and daily life of the travelers who once passed through. The site offers a unique blend of history and nature, where you can observe the routes once traveled by merchants and the natural terrain, including landforms shaped by historical landslides.
As an outdoor historical site, Tochimoto Sekisho is beautiful in every season. The Chichibu area is famous for its rich natural scenery, offering changing views throughout the year. Visiting during daylight hours is highly recommended, as it allows for a clearer observation of the terrain and the ancient routes that once connected the provinces.
