The Former Otsuka Family Residence is a historic traditional house located in Horai 3-chome, Urayasu City, Chiba Prefecture. Designated as a Tangible Cultural Property, the residence is an important part of Urayasu’s cultural heritage.
Believed to have been built during the late Edo period, the house was the home of the Otsuka family, who made their living through fishing and agriculture. Its traditional architecture provides a valuable glimpse into everyday life in Urayasu before modern urban development.
One of its most interesting features is the way the house was adapted to the area’s frequent flooding. The building reflects the practical knowledge and ingenuity of local residents who had to live alongside a challenging natural environment.
The Former Otsuka Family Residence is a wooden house believed to have been constructed during the late Edo period. It was relatively large for a private residence in Urayasu at the time.
The Otsuka family was engaged in both fishing and agriculture, two important occupations in the local community. The house therefore provides valuable insight into the lifestyle of people whose livelihoods depended closely on the surrounding waterways, farmland, and natural environment.
The main living area is located in the center of the house, while an earthen-floored area, or doma, is positioned on the side closer to the Sakai River.
The building is a single-story wooden structure with a distinctive hipped thatched roof. An unusual feature is the small second level within the attic, which could be accessed from the entrance and doma.
This arrangement was not simply an architectural curiosity. It was a practical response to the area’s recurring floods and provided a place where household belongings and other valuables could be moved to safety when floodwaters threatened the home.
Urayasu historically experienced frequent flooding, and the Former Otsuka Family Residence preserves evidence of how residents adapted their homes to these conditions.
The attic-level space could be used to protect furniture, household goods, and valuables during floods. This simple but effective solution demonstrates the practical knowledge developed by local residents through generations of experience with their environment.
For visitors interested in traditional Japanese architecture, the house is particularly valuable because its structure illustrates how buildings were adapted to local climate and natural hazards.
Another distinctive feature of the residence is the presence of both a Shinto household shrine and a Buddhist altar within the same living space.
This arrangement provides an example of how different religious traditions were incorporated into everyday family life. Rather than being separated from ordinary living, religious practices formed a natural part of the household environment.
The Former Otsuka Family Residence is primarily a single-story wooden house with a partial attic-level second floor. Its hipped thatched roof and traditional construction techniques preserve characteristics of residential architecture from the late Edo period.
Although the precise construction date has been estimated rather than definitively established, the structure provides valuable evidence for understanding the development of traditional architecture in the Urayasu area.
The residence was designated as a Tangible Cultural Property of Urayasu City in 1987. It was subsequently designated as a Tangible Cultural Property of Chiba Prefecture in 2002.
These designations recognize the historical and architectural importance of the house and support its preservation as part of the region’s cultural heritage. The residence is also open to the public, allowing visitors to experience a traditional home in a way that would not be possible through historical documents alone.

The residence can also encourage visitors to think about disaster preparedness and living in harmony with the natural environment.
Long before modern flood-control systems and disaster-prevention technology existed, local residents developed practical ways to protect their homes and possessions. Learning about these historical adaptations provides an interesting perspective on how communities have responded to natural hazards throughout history.
