The Gate That Has Stood Since the School Opened
Along the western edge of a campus in central Okayama runs a low stone wall, and at one point it opens through four square stone pillars into the grounds of a high school. The gate dates from 1900, the year the Sixth Higher School first received students, which makes it the oldest registered element of the entire site. For more than a century it has marked the boundary between the public street and a place of study, and generations of students have passed between its pillars on their first and last days.
The gateway is built entirely of cut stone. Four rectangular piers carry the structure, with a central opening of 4.2 meters flanked by side openings of about 1.5 meters, each fitted with timber doors. Smaller service gates sit to either side. The whole is plain and four-square, the kind of restrained entrance that a national school of the Meiji era considered fitting to its standing.
A Wall More Than a Kilometer Long
The gate is only the visible focus of a much longer work. The registered property also takes in the stone wall that encircles the grounds, running a total of 1,032 meters at a height of about 1.5 meters. That length, more than a kilometer of masonry, traces nearly the full perimeter of the campus and gives the school its enduring outline within the surrounding streets.
The wall repays a close look at how the stones are laid. The builders used split stone in two different coursing patterns. In some stretches the blocks are set on the diagonal in the pattern called tanizumi, so the joints form a lattice of diamonds; in others they run in level horizontal courses, the method known as nunozumi. Reading the wall as you walk beside it, you can pick out where one technique gives way to the other.
Why the Gate and Wall Were Registered
Both gate and wall were entered together onto Japan's register of Tangible Cultural Properties in January 2011, in the sixty-ninth round, under reference number 33-0238. The designation honors structures that contribute to the historic landscape of their district, and here that contribution is unusually direct. The Sixth Higher School was founded in 1900 by imperial ordinance as the first wholly new higher school of its kind, and it became known for the strength of its athletic clubs and for sending graduates to the imperial universities.
When an air raid in June 1945 destroyed the school's main buildings, the stone gate and wall came through largely intact, as masonry tends to. The school passed into Okayama University in 1949 and the site to the present high school, and these stone elements remained as the most continuous physical link back to the founding. A repair was carried out around 1989, but the gate and wall keep the dignity of a long-established institution. Because they line the public street, they are also the part of the registered group that a passerby can take in without entering the grounds.
