What the Chishinkan Front Gate Is
The Chishinkan Front Gate (知新館表門, Chishinkan omotemon) is a timber bracket-armed gate in Minamishinza, Tsuyama City, Okayama Prefecture, built in 1937 and registered as a Registered Tangible Cultural Property in 1998.
It is the street entrance to the house rebuilt on the birthplace of Hiranuma Kiichirō, and it lines up directly with the entrance of the main house. The gate stands 2.8 metres high and 3.8 metres wide. Its tiled roof rests on arms, or udegi, that pass through the posts and project front and back, the form known as an udegimon. The Agency for Cultural Affairs describes it as a gate of three bays with a single opening, with the street wall attached on both sides.
This is not a temple gate or a castle gatehouse. At under 3 metres, the Chishinkan Front Gate is a restrained house gate suited to the rank of the residence, and what repays a closer look is the care taken in how it is set on the ground.
Why the Chishinkan Front Gate Was Registered
The Chishinkan Front Gate was registered as a structure that contributes to the historic landscape of the country. A house gate on the street is the part of a residence passers-by notice most, and it does much to shape the character of a former samurai quarter.
The Agency for Cultural Affairs points to two things. First, the gate uses a simple form, with arms holding up the roof, and is fairly small. Second, it still shows deliberate design: the gate is set slightly below the level of the road, and its approach is treated like a small stone bridge.
An udegimon generally uses fewer members than a Shikyakumon or a Yakuimon and is a plain type of gate. Okayama Prefecture describes the combination of gate, wall, main house and storehouse at Chishinkan as typical of a middle-ranking samurai home. That a modest gate was chosen when the Hiranuma residence was re-created, rather than something grander, is a useful clue when looking at the Chishinkan Front Gate.
What to Look for at the Chishinkan Front Gate
A Gate Set Below the Road
Standing in front of the Chishinkan Front Gate, you can see that its threshold sits a little lower than the road surface, so entering means stepping down across a short drop. The stone-bridge-like approach turns that change of level into a feature and marks a small threshold between street and house.
Arms and Roof
Look at the tops of the posts from the side and you can see the arms running through them and carrying the eaves forward and back. The roof is covered in Sangawara-buki pan tiles. Because the form is so simple, the proportions of the timbers largely decide how the gate reads; the ends of the ridge and the cut ends of the arms are worth a second look.
Where Gate Meets Wall
The street wall joins the Chishinkan Front Gate on either side, making one continuous frontage. Notice how the wall's roof meets the gate's roof at each side: the junction shows how the designer tried to treat the whole street front of the house as a single composition.
Seeing the Chishinkan Front Gate
Because it faces a public road, the Chishinkan Front Gate can be seen from outside at any time without a booking. To check how low it sits and how the bridge-like approach works, step back to the opposite side of the road and look at it head-on; the same spot is best if you want the gate and wall together in one view.
The doors of the Chishinkan Front Gate are usually closed. Passing through to the entrance of the main house is possible on a visit reserved with Tsuyama City, and on such a visit you can also see the arm joints up close from inside the gate.
