The Usui Sekisho Ruins mark the site of a once-vital checkpoint on the Nakasendo, one of Japan's most important ancient highways. Established by the Edo Shogunate, this location served as a strategic gateway to control movement into the Kanto region. Today, visitors can experience the atmosphere of the early modern era through the reconstructed gates and the historical archives located nearby, offering a profound look into Japan's traditional transportation culture.
The Nakasendo was a vital transport route during the Edo period, and this checkpoint was essential for monitoring travelers. The Shogunate maintained strict surveillance to control the influx of weapons and regulate the movement of women (known as 'demme') to ensure regional security. The site featured gates on both sides, with the Shogunate managing the western side and the Annaka Clan overseeing the eastern side. It was not merely a transit point, but a significant political and military boundary in Japanese history.

The site features reconstructed gates that faithfully represent the architectural style of the era. Some components, such as the gateposts and roofing materials, utilize traditional methods to preserve the historical weight of the structure. Additionally, the 'Asao Chaya' building houses the Usui Sekisho Historical Exhibition Room. Here, various documents and artifacts related to the checkpoint and the transportation culture of the time are displayed, allowing visitors to gain a concrete understanding of how people lived and traveled during the Edo period.
In spring (around March to April), the area is beautifully framed by blooming cherry blossoms. The contrast between the historic, weathered architecture of the gates and the soft pink of the cherry blossoms creates a stunning, picturesque scene. Furthermore, in May, the area may host the 'Ansei Ensoku' (Samurai Marathon) festivities, where traditional performing arts like Shishimai (lion dances) and Yagibushi folk dances are often showcased.

Visitors can learn about the sophisticated historical transportation systems of Japan. Through the exhibits in the archives, you can deepen your understanding of the social systems and modes of travel used during the Edo period. During certain periods, local guides may provide explanations to offer even deeper historical insights.
The area is rich in railway-related culture and historical landscapes along the old highway. You can feel the history of the Nakasendo as you walk the path from Sakamoto-juku toward Kumano Shrine. The site is conveniently located within walking distance of Yokokawa Station, making it an easy stop for travelers using the rail network.
As you will be exploring both indoor exhibition rooms and outdoor historical remains, comfortable walking shoes are highly recommended. The exhibition room is open from 9:00 AM to 4:30 PM (last entry at 4:00 PM). Please note that the exhibition room is closed during the New Year holidays. Local historical commentary is typically scheduled for Saturdays, Sundays, and public holidays during April, May, October, and November.
