Onarimon Formal Gate and Wall, Hirao Family Residence
A house that received rank and ran a great agricultural estate needed a considered face, and the Hirao Family Residence in Toyooka has many. The Hirao served as great village headmen and were among the leading landowners of Tajima; within their roughly 4,000-square-metre grounds, some twenty buildings and a sequence of gates and walls, raised from the Edo period into the early Showa era, order the approach and the interior alike.
The Structure Itself
On the south side of the detached quarters, facing the Morio River, stands the onarimon. The name marks it as a gate of honour, the entrance reserved for the formal arrival of a distinguished guest, and it is built accordingly: a bracket gate 2.5 metres across under a gabled pantile roof, with a 1.4-metre pair of hinged doors at the centre and white-plastered panels, boarded to the waist, at either end.
From the gate's flanking walls a longer wall extends about 27 metres along the river, set with a horizontal lattice window and a small wicket for everyday passage. The white plaster and the river frontage together give this stretch a more ceremonial character than the working gates elsewhere in the compound, a reminder that a headman's house needed a proper face to receive rank.
Why It Was Registered
The estate was registered as a Tangible Cultural Property in 2008, recognising how completely the framework of a great landowner's compound, its main house, quarters, storehouses, walls and waterworks, survives here as a single ensemble. Each registered element earns its place less as a solitary monument than as one part of that larger, coherent whole.
Seeing It Today
The Hirao Family Residence remains a private home and is, as a rule, not open to the public. Visitors should not expect interior access, and the family's privacy asks for a respectful distance. The exterior and its river setting can be appreciated from the public road nearby, and travellers to this corner of Tajima can pair a passing look with the region's more accessible sights: the willow-lined hot-spring town of Kinosaki Onsen, the old castle town of Izushi with its soba and clock tower, and the columnar basalt cliffs of Genbudo Park along the Maruyama River.

Q&A
- Can I go inside the Hirao Family Residence?
- No. The residence is privately owned and generally closed to the public. You can view its exterior and river setting from the adjacent public road, but please respect the residents' privacy.
- What does onarimon mean?
- Onari refers to the formal visit of a person of high rank, so an onarimon is a gate reserved for such an honoured arrival. Its more ceremonial finish sets it apart from the everyday working gates of the estate.
- How old is this part of the estate?
- It dates to the mid-Meiji period (1868–1911). The estate as a whole was built up across generations, from Edo-period storehouses through the 1896 main house to early-Showa additions, so its elements span more than a century.
- What else can I see nearby?
- Toyooka offers Kinosaki Onsen for its hot springs, the castle town of Izushi for soba and historic streets, and Genbudo Park for its dramatic columnar basalt, all within easy reach of the Morio district.
