The Nakagawa Bansho inspection facility played a vital role keeping track of ships coming and going in the network of waterways that underpinned the transportation of consumer goods in the de facto capital during the Edo period (1603-1867).
While the facility is long gone, the Nakagawa Funabansho Museum is located near the checkpoint's original location at a well-positioned juncture where the Onagi River flows into the Kyunaka River in what is now Koto Ward, Tokyo. Visitors to the museum can learn about the history of inspection control and water transportation during the Edo period and beyond.
Waterways for the distribution of goods were developed shortly after warlord Tokugawa Ieyasu moved to the Kanto region in the late 16th century. The Onagi River was dug on his orders primarily for transporting salt from Gyotoku, in present-day Ichikawa, Chiba Prefecture. In 1661, the Nakagawa Bansho was established and for more than 200 years the inspection facility monitored the flow of barges and ships that traveled between Edo and other parts of the Kanto region as well as what is now the Tohoku region.
Rice and sake were some of the mainstays entering Edo on boats, and workers at the inspection facility checked travel passes, goods and their quantities, which helped to contribute to the Tokugawa shogunate's price control policy. The Nakagawa Bansho was also used to enforce crackdowns on guns coming into the city and women leaving the city. Visitors to the museum can also take a look at a replica of a travel pass.
But the museum's centerpiece is a full-scale replica of the Nakagawa Bansho replete with a shogunate official inspecting a moored barge laden with bags of rice and barrels of sake from areas outside Edo. Over a sound system, visitors can hear a voice asking the bargeman, "Do you have a travel pass?!" Furthermore, the lights in the room mimic the passing of time from morning to evening.
The replicated scene is based on findings from an excavation survey conducted in 1995 as well as drawings from the Edo period.
Water transportation after the 1868 Meiji Restoration is also featured at the museum. By that time, the Nakagawa Bansho was no longer used as an inspection facility. But its location on the Onagi River, which had a direct link to the capital, gained importance as modernization, with steamships for instance, progressed. The samurai residences of the area were gradually replaced with rows of factories, and the museum features a scaled-down diorama of steamships and Japanese wooden ships making their way up and down the river.
In modern-day Tokyo, condominiums dominate its riversides and the once-surging boat traffic has been reduced to a trickle. But along a stretch of the Onagi riverbank, an Edo-period promenade dubbed "the salt road" still gives people on foot a taste of what the once mighty Edo waterways were like.
Yoko Kobari, a 54-year-old staff member at the museum, said, "We want people to know the contribution made by Nakagawa Bansho to the protection of Edo, together with the history of water transportation that underpinned the global megacity."
