TheMartyrs of Japan (Japanese:日本の殉教者,Hepburn:Nihon no junkyōsha) wereChristian missionaries and followers who were persecuted and executed, mostly during theTokugawa shogunate period in the 17th century.More than 400 martyrs of Japan have been recognized withbeatification by theCatholic Church, and 42 have beencanonized as saints.

Christian missionaries arrived withFrancis Xavier and theJesuits in the 1540s and briefly flourished, with over 100,000 converts, including manydaimyōs inKyushu. The shogunate and imperial government at first supported theCatholic mission and the missionaries, thinking that they would reduce the power of theBuddhist monks, and help trade withSpain andPortugal. However, the Shogunate was also wary ofcolonialism, seeing that theSpanish had taken power in the Philippines, after converting the population. It soon met resistance from the highest office holders of Japan.Emperor Ōgimachi issued edicts to ban Catholicism in 1565 and 1568, but to little effect.[1] Beginning in 1587 with imperial regentToyotomi Hideyoshi's ban on Jesuit missionaries, Christianity was repressed as a threat to national unity.[2] While the Japanese view was that Christians were persecuted and executed for being more loyal toJesus than theShogunate, the Catholic Church viewed them as martyrs: As the persecution was aimed at Christians as a group, and as they could escape only byabjuring their faith, the Catholic Church regarded the acts as beingin odium fidei ("in hatred of the faith"), a principal factor in martyrdom. After the Tokugawa shogunate banned Christianity in 1614, it ceased to exist publicly. Many Catholics went underground, becominghidden Christians (隠れキリシタン,kakure kirishitan), while others lost their lives. Only after theMeiji Restoration was Christianity re-established in Japan.

TheTwenty-six Martyrs of Japan (日本二十六聖人,Nihon Nijūroku Seijin) refers to a group ofChristians who were executed bycrucifixion after a forced march from Kyoto toNagasaki. with the crucifixion taking place on 5 February 1597 at Nagasaki.

Persecution flared episodically and over a period of 15 years, between 1617 and 1632, 205 missionaries and native Christians are known to have been killed for their faith, 55 of them during theGreat Genna Martyrdom, a further 50 during theGreat Martyrdom of Edo (but only three were beatified as part of the 205 Martyrs of Japan).[4] Christianity was proscribed and forced underground until the arrival of Western missionaries in the nineteenth century.

Two SpanishAugustinian Recollects arrived in Japan in the later half of 1632 from Manila to evangelize the Japanese. Upon arrival, Japanese authorities were notified by the Chinese merchants who had given them passage. They fled into the mountains whereDominican missionaries instructed them in the language of the country. When they descended into the city they were recognized and arrested in November 1632. On 11 December 1632, they were martyred for their faith.[6]
