A School Gate Older Than the Prefecture Owned It
The Main Gate Pillars of Aichi Prefectural Hekinan High School (Former Main Gate of Aichi Hekinan Kokumin School), in Japanese 愛知県立碧南高等学校正門門柱, are a pair of granite posts of about 1929 standing on the south side of the school grounds at 12 Koyo-cho 4-chome, Hekinan City, Aichi Prefecture, and they were entered on the national register as a Registered Tangible Cultural Property on 28 June 2017. Students still walk between them every morning.
The school opened in 1926, founded by an association of four towns and villages under the name Aichi Hekinan Kokumin Gakkō. The name is worth pausing over. Fifteen years later, in 1941, the Kokumin Gakkō Order turned every elementary school in Japan into a school of that name, but this institution had carried the title from the start and was a secondary school, not an elementary one.
A new campus on the present site was finished in 1927, and the gate was cut and set between 1927 and 1929. The prefecture's registration document dates it to around 1929, with alterations around 1962. Since then the school has changed its name four times, and the posts have stayed where the school put them.
Why a Pair of Posts Was Registered
The criterion applied was the one for structures that contribute to the historical landscape of the country. A gate is the part of a school that the neighbourhood sees, and the Main Gate Pillars of Aichi Prefectural Hekinan High School have marked the same corner of the city for close to a century.
The registration was not made alone. On 28 June 2017 the gates of thirteen prefectural high schools across Aichi were registered together, and the Aichi Prefectural Board of Education describes this batch registration of school gates as the first of its kind in Japan. The survey behind it, carried out in 2015, found twenty-eight historic structures on twenty-four prefectural school campuses.
Within that group the Main Gate Pillars of Aichi Prefectural Hekinan High School sit slightly apart. Several of the other gates registered on the same day are reinforced concrete built to look like coursed stone, following a standard prefectural design of the 1920s. The Hekinan posts are granite, cut from the block.
Reading the Stone
Each post of the Main Gate Pillars of Aichi Prefectural Hekinan High School (Former Main Gate of Aichi Hekinan Kokumin School) stands 2.75 metres high, and the opening between them measures 6.4 metres. The surface is worked in the finish called kobu-dashi: only the four corners of each face are dressed smooth, and the centre is left deliberately lumpy, the tool marks answered by a coarse chisel finish across the rest. The result changes with the hour. In flat midday light the posts look almost plain, and in low side light the whole surface breaks into shadow.
What stands today is a fragment. A photograph of the school's first graduating class, taken in March 1929 and still held at the school, shows a gate of four posts: two main ones and two narrower side posts. Each main post then had a shaft and a separate head, with a capstone and a spherical lamp on top. The capstone resembled the one surviving at Iwazu High School.
The alteration around 1962 widened the opening. The main posts were moved outward, their heads were taken off, and only the shafts were reset, which is why each post reads today as a single length of stone with nothing above it. The side posts were removed altogether. Walk east across the grounds and look at the posts of the east gate: from the surface working and the traces left on the stone, the prefecture's registration document concludes that these are most likely the old side posts, reused upside down. The registered unit also takes in the low earthwork retainers running east and west from the main posts.
Visiting
This is a working high school, not a museum, and that shapes everything about a visit. The Main Gate Pillars of Aichi Prefectural Hekinan High School face a public road on the south side of the campus, so the posts can be seen and photographed from outside the grounds at any hour, with no admission fee and no opening times to check. Entering the grounds needs the school's permission, and the number for enquiries is 0566-41-2564.
The east gate posts, the ones that appear to be the reused side posts, stand inside the campus, so seeing them closely also depends on that permission. Term-time weekday mornings and late afternoons are the worst moments to turn up, since that is when students are passing through. Photograph the stone rather than the pupils.
By train, take the Meitetsu Mikawa Line to Hekinan-Chūō Station, about eight minutes on foot from the school. The school gives the rail journey as about twenty-eight minutes from Kariya and about thirty-five from Chiryū.
