Oura Church Overview
Standing at the foot of Minami-Yamate hill in Nagasaki, Oura Church — formally known as the Basilica of the Twenty-Six Holy Martyrs of Japan — is one of the most historically significant religious sites in the country. Completed in 1864 by French missionaries Father Louis Furet and Father Bernard Petitjean, it is recognized as the oldest surviving Catholic church in Japan and the only pre-Meiji Western-style building to be designated a National Treasure.
The church was built to serve the foreign merchant community that had settled in Nagasaki following the reopening of Japan’s ports in 1859, and it was deliberately oriented to face Nishizaka Hill, the site where 26 Christians — six missionaries and 17 Japanese believers, along with three others — were executed in 1597. Those martyrs were canonized by Pope Pius IX in 1862, just two years before the church’s construction began. In 2016, Oura Church was elevated to the status of a minor basilica, and in 2018 it was inscribed as a UNESCO World Cultural Heritage site as part of the Hidden Christian Sites in the Nagasaki Region.
Perhaps the most remarkable chapter in the church’s history unfolded in March 1865, just a month after its dedication ceremony. A group of villagers from Urakami approached Father Petitjean and revealed that they had secretly maintained their Christian faith for over 250 years during Japan’s ban on the religion. This event — known as the “Discovery of the Hidden Christians” — was described by the pope as the “miracle of the Orient.”
Inside, the Gothic-style interior features French stained glass windows, vaulted ceilings crafted by Japanese carpenters and a serene altar. An adjacent Christian Museum, housed in the former Latin Seminary and former Archbishop’s Residence, is included in the admission fee and provides exhibits on the history of Christianity in Japan.
Best Times To Visit Oura Church
Oura Church is open year-round, though spring and autumn offer the most comfortable temperatures for exploring the surrounding Minami-Yamate neighborhood on foot. Weekday mornings tend to be quieter, providing a more contemplative atmosphere inside the church. Late afternoon is also a good time to visit, with softer light filtering through the French stained glass creating a particularly atmospheric interior. Since photography is generally not permitted inside the church, plan to linger and absorb the space rather than rush through it.
The church is an active place of worship, so visitors are asked to dress modestly — covered shoulders are recommended.
