What Is Ōura Cathedral (Nagasaki)? Japan’s Oldest Surviving Christian Church
Ōura Cathedral is Japan’s oldest surviving Christian church, located in Minamiyamate, Nagasaki City, and completed in 1864 (Genji 1).
Its official name is the “Cathedral of the Twenty-Six Holy Martyrs of Japan,” dedicated to the Twenty-Six Martyrs who were executed at Nishizaka in Nagasaki in 1597.
It was inscribed in 2018 as part of the UNESCO World Cultural Heritage property “Hidden Christian Sites in the Nagasaki Region,” and it is also designated a National Treasure of Japan.
This Gothic-style church is a historically significant site associated with the “Discovery of the Hidden Christians,” which took place after roughly 250 years of Christianity being banned in Japan.
Highlights of Ōura Cathedral
1. The Discovery of the Hidden Christians: A Landmark Event in Religious History
Ōura Cathedral was completed in 1864 under the design guidance of the French missionaries Father Furet and Father Petitjean, and built by the master carpenter Hidenoshin Koyama from Amakusa.
A dedication ceremony was held in February 1865, and it was initially used as a chapel for French residents living in the foreign settlement.
About one month after the ceremony, on March 17, 1865, Hidden Christians from Urakami visited Ōura Cathedral and confessed their faith to Father Petitjean, saying, “Our hearts are the same as yours.”
This revelation—that people had endured persecution and preserved their faith in secret for about 250 years—shocked the Catholic world and became known as the “Discovery of the Hidden Christians.”
2. Beautiful Gothic Architecture and National-Treasure Stained Glass
Its Gothic features, such as pointed arches and a rib-vaulted ceiling, are especially striking.
One highlight is the fusion of Western and Japanese techniques—for example, the ceiling base uses takekomai (a traditional Japanese bamboo-lath method).
Some of the stained glass inside dates back to the 19th century, creating an atmospheric, luminous interior.
Originally built of wood, the cathedral later underwent expansions and renovations, with brick walls added to form its current appearance.
3. A Component Site of the UNESCO “Hidden Christian Sites in the Nagasaki Region”
In 2018, it was inscribed as a UNESCO World Cultural Heritage component site of “Hidden Christian Sites in the Nagasaki Region.”
Among the 12 component sites, it is the only building, valued as a place that symbolizes the end of the Hidden Christians’ period of concealment.
In 1953, it became the first Western-style building in Japan to be designated a National Treasure, and in 2016 it was also recognized as Japan’s first minor basilica.
