The Key to Edo’s Security: Japan’s Only Remaining Sekisho (Checkpoint)
The Arai Sekisho (新居関跡) is the only remaining checkpoint in Japan and is designated as a Special Historic Site by the national government. Established during the Edo period, this checkpoint was founded by Tokugawa Ieyasu (徳川家康) in the 5th year of the Keichō era (1600) to play a crucial role in protecting Edo. Among the 53 checkpoints across the country, the Arai Sekisho was known for its strict enforcement, with the highest level of security to prevent "incoming guns and escaping Daimyo's wives."
The Arai Sekisho, also known as the Imakita Sekisho, was originally located near the Imakita entrance of Lake Hamana. However, it was moved to its current location after being damaged by a storm in the 12th year of the Genroku era (1699) and a tsunami in the 4th year of the Hōei era (1707). The current buildings were reconstructed by the 5th year of the Ansei era (1858) after the original structures collapsed in an earthquake in the 7th year of the Kaei era (1854). Although the checkpoint was abolished in the 2nd year of the Meiji era (1869), it continued to be used as a school and town hall, preserving its historical value.
The Arai Sekisho site features several buildings, including the face-off building and the Onna Aratameno Nagaya, which are open to the public. Visitors can also enjoy a VR experience comparing the Edo period landscape with the modern view. The adjacent Arai Sekisho Historical Museum exhibits materials related to the checkpoint displays the history of roads and transportation and hosts special exhibitions and events.
Restoration work is ongoing at the Arai Sekisho site, including reconstructing the stone walls and embankments at the Imakita Ferry Terminal, the masu-gata plaza, the notice board area, the Ōmi gate, and the Onna Aratameno Nagaya. Plans include additional structures such as the boat house and storehouses, enhancing the site’s appeal as a tourist destination.
