Hirose Family Main House

Hirose Family Residence Main House: A Merchant's Home Raised by a Temple Carpenter

A few minutes' walk from the crowds at Tsudanuma Station, a low tile-roofed house sits behind a quiet wall in the Tsudanuma district of Narashino, in Chiba Prefecture. The shopfront facing the street has been rebuilt, but the rooms behind it have barely shifted since the closing decades of the Edo period: a broad hall of twelve and a half tatami mats, a ten-mat storeroom, and three parlors set in a line.

This is the Hirose Family Residence Main House (Hirose-ke Jutaku Shuoku), one of four buildings on a single property that Japan entered in its register of cultural properties in 2003. It remains a privately owned family home and is not open for tours. It is worth knowing all the same, because few buildings show so plainly how a country carpenter's skill and a grain dealer's trade once lived under one roof.

From the Old Village of Kukuta to a Shop on the Highway

The main house went up in the late Edo period, somewhere between the 1830s and the 1860s, in a settlement then called Kukuta-hongo. Around the end of the Meiji era — roughly 1900 to 1911 — it was dismantled and re-erected on its present site, where it was adapted to serve as a shop as well as a home. The front, lower portion that became the storefront was rebuilt at that point. The inner rooms kept their older form.

According to the city of Narashino, the house is the work of Hirose Yahei, a family ancestor known as a miyadaiku, a carpenter trained in the exacting craft of shrines and temples. Local accounts credit him with the Nio gate of Hokekyo-ji, the head Nichiren temple in what is now Ichikawa. A temple carpenter building his own dwelling was unusual, and it accounts for the care still visible in the surviving joinery.

Reading the House: Marks of a Boso Farmhouse

What the registration singles out is how much of a traditional Boso-peninsula dwelling survives here. On the east side are the remains of a shikidai, the slightly lowered plank step where a household once received its more formal guests. Along the south runs an en, the wooden veranda that mediates between garden and interior in older Japanese homes.

The inner rooms read almost like a diagram of rural status and routine. The twelve-and-a-half-mat hiroma was the main gathering space. The ten-mat nando doubled as storeroom and sleeping chamber. The three zashiki — of four, six, and six mats — gave a prospering merchant household the graded formal rooms it needed. Single-story and tiled throughout, the house covers about 118 square meters.

A Complete Merchant Estate, and Why It Was Registered

Japan's registration system, introduced in 1996, is a lighter touch than the better-known designations for National Treasures and Important Cultural Properties. It protects buildings at least half a century old that remain in everyday use, nudging owners to preserve them rather than freezing them in place. The four Hirose buildings were the third such registration in Narashino, and the first private residence in the city to receive it.

Beyond the main house, the property keeps the working bones of a zakkoku-don'ya, a wholesaler in millet, barley, and other grains. A two-story earthen storehouse from 1891 stands to the south, its ridge tablet naming the carpenter Murayama Iwakichi of Saginuma, its interior braced with heavy beams. A 1909 warehouse, moved and remodeled around 1935, uses the kakuyose-gura method, in which closely spaced posts and plank walls replace thick mud plaster. A small open-sided wellhead canopy of 1935 completes the group. The estate sat on the strip of land between the old shoreline and the Kazusa highway — the kind of spot where a grain trader could move goods by both road and water.

The man who assembled this ensemble, Hirose Akinosuke, was born in 1865 and went on to serve as a town councilor and local official. The family also preserved a library of Edo-period books from the private academies where he studied, including texts on wasan, Japan's indigenous mathematics — a paper trail of a merchant house that valued learning as much as ledgers.

Around the Neighborhood

Narashino faces Tokyo Bay, and the land around the Hirose house has been reshaped by a century of reclamation. The nearest reason to linger is Yatsu-higata, a rare surviving tidal flat now protected under the Ramsar Convention. Its observation center is a fine place to watch migratory shorebirds work the mud at low tide. Beside it, the Yatsu Rose Garden plants some 7,500 roses across roughly 800 varieties, at their best in late spring and again in autumn. A stone marker at its entrance recalls that this ground was once the practice field of Japan's first professional baseball team.

Both lie a short bus ride from Tsudanuma Station — the same hub that puts the Hirose house within walking distance — or a few minutes' walk from Keisei Yatsu Station. Central Tsudanuma itself is a busy quarter for shopping and a meal before or after.
