Gatepost of the Main Gate of Aichi Prefectural Tsushima High

The School Gate That Became a Cultural Property

Most people who come to Tsushima are heading for the wisteria in spring or the lantern-lit boats of the summer river festival. Almost no one makes a point of visiting the front gate of the local high school. Yet the pair of concrete pillars at the entrance to Aichi Prefectural Tsushima High School has stood in place since about 1923, and in 2017 it was added to Japan's national register of cultural properties.

The official listing is a mouthful: the Front Gate Pillars of Aichi Prefectural Tsushima High School, formerly the main gate of Aichi Tsushima Middle School. In plain terms it is a single reinforced-concrete gateway from the Taishō era (1912 to 1926), built when the campus belonged to the school that would later become today's Tsushima High. It sits in Miyagawa-chō, in the western Aichi city of Tsushima, and is owned by Aichi Prefecture. A century on, students still walk through it every morning.

The school behind the gate has deep roots. It began as Aichi Third Middle School, which opened in April 1900 as one of the prefecture's early "number schools," brought to Tsushima largely through the efforts of the town mayor of the day. In 1948 the boys' middle school merged with the local girls' high school to form the coeducational institution that exists now. The gate dates from somewhere in the school's third decade, a survivor of nearly every change the campus has been through since.

Why a Gate Earns Protection

Japan looks after its cultural heritage through two different mechanisms, and the difference matters here. The older one is designation, which produces the famous categories of National Treasure and Important Cultural Property and is reserved for objects and buildings of the very highest value. The second, introduced in 1996, is registration. It carries lighter regulation and was created largely to protect modern structures that shape the texture of everyday life. The Tsushima gate belongs to this second track: it is a Registered Tangible Cultural Property in the buildings category, entered on 28 June 2017 under registration number 23-0487, on the ground that it contributes to the historic landscape of the nation.

What gives the listing its character is how it came about. The idea did not start with scholars but with graduates and residents who told the prefectural board of education that their old school gates were worth something. A 2015 survey of all 54 prefectural high schools turned up thirteen gates that pre-dated 1948 and were still in daily use as working entrances, rather than retired into a corner of the grounds as monuments. Over the next two years the prefecture talked through the implications with each principal, since registration means future repairs come under review. Every school chose to keep its gate in service and protect it at the same time. A research group from Nagoya University documented the thirteen with measured drawings and photographs, and in June 2017 all of them were registered together, the first time the prefecture had ever listed the gates of its high schools. Tsushima's was one of the thirteen.

What to Look For

Up close the gate is a quiet lesson in early-modern Japanese design. The pillars are reinforced concrete with a mortar surface, nearly square in plan. The two main pillars rise to about 3.5 metres, with shorter side pillars of about 3.1 metres, and the whole composition spans a frontage of roughly 10 metres, finished at the ends with side pillars and a low earthwork retaining detail. The national database and the Tsushima city heritage page differ slightly on the figures, with the city listing the pillars at 3.9 metres, so treat the exact measurements as approximate.

Look at the surfaces and the logic of the design starts to show. Every pillar follows the same vocabulary, but the horizontal joint lines are set at different intervals as they climb, which keeps a tall concrete post from feeling monotonous. The capitals carry restrained geometric patterns, and the body reads in three stacked tiers. There is nothing here of a temple gate or a shrine torii. This is the sober, geometric idiom of the 1920s, concrete still a fairly young material in Japan, ornament pared back to pattern.

The most appealing thing about it cannot be photographed in a single frame. The gate is still doing the job it was built for. The registration protects a structure that has never been retired or roped off, one that a few hundred teenagers pass through on an ordinary school day. That continuity, a hundred-year-old gate still opening onto the same courtyard, is the point.

A practical note before you go: this is the entrance to an active school, not a sightseeing spot. You can see the pillars clearly and take photographs from the public road outside, but the campus is not open to casual visitors. Think of it as a brief, free stop folded into a longer walk around Tsushima.

Around the Gate

Tsushima makes an easy half-day, and the gate connects neatly to the rest of it. A short walk away is Tennōgawa Park, the city's wisteria showcase. Tsushima was once known as Fujinami no Sato, the village of wisteria waves, and the flower remains the city's emblem. There is a small echo worth knowing: the school's own badge pairs a three-pointed prism crest with a drooping-wisteria motif borrowed from that heritage, so the gate and the gardens share a thread. The park's wisteria trellis runs some 275 metres and blooms from the middle to the end of April, when the Owari Tsushima Wisteria Festival lights the flowers after dark.

A few minutes further sits Tsushima Shrine, the head shrine of the Gozu-Tennō tradition. Its summer rite, the Owari Tsushima Tennō Festival, counts among Japan's three great river festivals and reaches back roughly 600 years. The boat procession at its heart is a nationally designated Important Intangible Folk Cultural Property and forms part of the float festivals inscribed by UNESCO. On the festival eve, makiwara boats hung with more than five hundred lanterns drift out onto the water, one of the most photographed sights in the region.

Getting here is straightforward. Take the Meitetsu Tsushima Line to Tsushima Station, then walk about fifteen minutes toward the park and the shrine. The high school stands in the same district, so the gate slots easily into a loop that takes in the water, the wisteria and the shrine.
