A Brick Wall Built to Hold Back a River
Look closely at the ends of the brick wall fronting the Masuda residence and you will find a narrow vertical slot cut into the masonry. It is easy to walk past. Yet that groove explains why this otherwise modest wall, running 39 meters along a back lane in Noda, carries a national registration of its own. When the Edo River rose and threatened to spill over its bank, the household dropped wooden boards down into the slots, turning the gateways into a low dam and keeping the floodwater out of the yard.
The wall belongs to the former home of the Masuda Nizaemon family, river-shipping merchants who once worked one of the busiest landings on this stretch of the Edo. Japan's Agency for Cultural Affairs registered it as a Tangible Cultural Property in June 2013, together with the family's storehouse, side gate, and small shrine. The main house had been registered six years earlier.
Merchants of the Lower Wharf
The Masuda family opened for business in 1712 at a landing called Shimogashi, the "lower wharf," on the Noda side of the Edo River. They were wharf wholesalers, the kind of operation that arranged cargo, lodged boatmen, and kept goods moving between the farmland of the interior and the markets of Edo, today's Tokyo.
What kept them prosperous was soy sauce. Noda had grown into one of Japan's great brewing towns, and the river carried its essentials in and its product out: soybeans, wheat, and salt arriving by boat, barrels of finished shoyu floating downstream toward the capital. At its height the landing saw dozens of boats tied up at once.
The river trade did not last. A light railway reached the area in 1911, and after the Great Kanto Earthquake of 1923 trucks took over much of the freight that boats had carried. The Masuda business closed in 1938. Most of the wharves that once lined this water have since vanished, which is part of why the buildings that remain here matter. They are among the few physical traces left of how the Edo River once worked.
Reading the Wall
The wall is not uniform, and the differences repay a slow walk along its length. Facing the river embankment, the west front stands about a meter high. The openings here line up with the main house's formal entrance and with its earthen-floored work area, so the household could pass straight through toward the water.
Turn the corner past the side gate and the wall rises to roughly 2.7 meters. Along the top runs a band of dentil molding, a row of small projecting blocks borrowed from Western masonry and fashionable in Japanese brickwork of the late Meiji and early Showa years. Set into the taller section toward the west is a small window fitted with an iron grate.
Then there are the grooves. Cut vertically into the brick piers at the openings, they are the working heart of the wall. Drop a stack of boards into the paired slots and the gap becomes watertight. It is a quietly ingenious piece of flood engineering, built into something that also had to read as a respectable merchant's boundary.
The brickwork went up in stages. The earliest portions date to the late Meiji period, roughly between 1898 and 1912; later sections were added in the prewar Showa years.
Around the Site
The wall stands in a quiet residential pocket near the Edo River levee, and the house behind it is still lived in, so the interior is closed to visitors. The wall, the gate, and the storehouse are best appreciated from the lane outside.
Noda rewards anyone curious about soy sauce. A short trip away, the Kikkoman Soy Sauce Museum (Monoshiri Shoyu-kan) walks visitors through how shoyu is made and offers a factory tour by reservation; the souvenir shop and small café, where the soy-sauce soft-serve is worth a try, make an easy stop. Near the Edo River stands the Goyogura, the brewery that produces soy sauce for the Imperial Household. The town also holds other registered cultural properties, among them the Kofu Kaikan hall and the Mogi family residence, tied to the brewing houses that built Noda.
Getting here is straightforward. From central Noda, the community Mame Bus stops at Nakanodai-iriguchi, about a 10-minute walk away; the Ibakyu bus stops at Kamigashi, roughly 5 minutes on foot.

Q&A
- Can I go inside the house?
- No. The Masuda residence is a private home and remains in everyday use, so the interior is not open. You can view the brick wall, side gate, and storehouse from the public lane outside.
- What makes the wall worth a special look?
- It is a rare survivor from the Edo River's shipping era, and its grooved openings doubled as a flood barrier, a practical detail you can still pick out in the brickwork. The dentil molding and iron-grated window add to its period character.
- How long should I plan to spend?
- Viewing the wall from outside takes only a short while. Pairing it with the Kikkoman museum and a stroll along the river makes a comfortable half-day in Noda.
- Is there an entry fee?
- No. The wall is viewed from the public road, so there is no charge. Please respect the residents' privacy and keep to the lane.
