Inoue Enryō (井上円了?, March 18, 1858 – June 6, 1919) was a Japanese philosopher, Buddhist reformer, educator, and royalist. A key figure in the reception of Western philosophy, the emergence of modern Buddhism, and the permeation of the imperial ideology during the second half of the Meiji Era. He is the founder of Toyo University and the creator of the Temple Garden of Philosophy 哲学堂公園 in Tokyo. His Mystery Studies opposing superstition made him known as Ghost Doc or Doctor Specter お化け博士.
Early Years 1858-1881
Born in a village close to Nagaoka in today's Niigata prefecture, he was ordained as a priest in the Ōtani Branch 大谷派 of Shin Buddhism 真宗 at the age of 13. As the oldest son, he was brought up to inherit the ministry of his father's parish temple. His early education included the Chinese classics and Western subjects like geography and English. In 1878, his Buddhist order sent him to Tokyo in order to study at Japan's first modern university. Before entering Tokyo University in 1881 Inoue received additional secondary education in English, history, and mathematics in the university's Preparatory School.
Registering for philosophy as single major at Tokyo University first became possible in 1881. Inoue was the first and only student in 1881 to do so. As a student, Inoue initiated Japan's first Society of Philosophy (1884). On the occasion of his graduation in 1885, he created a Philosophy Ceremony 哲学祭 that commemorated Buddha, Confucius, Socrates and Kant as the Four Sages of world philosophy. In 1887, he set up a Philosophy Publishing House 哲学書院, edited the first issue of the Journal of the Philosophy Society『哲学会雑誌』and founded the Philosophy Academy 哲学館, the predecessor of today's Toyo University 東洋大学. His early works Epitome of Philosophy『哲学要領』(1886/86) and Outline of Ethics『倫理通論』(1887) are the first Japanese introductions to philosophy in East and West.
Besides establishing and popularizing philosophy, Inoue dedicated himself as a lay scholar to the critique of Christianity and the reform of Buddhism. The latter project he announced in the Prolegomena to a Living Discourse on Buddhism『仏教活論序論』(1887), which is the introduction to a tripartite work that aimed to give Buddhism a new doctrinal foundation for the modern world. In the Prolegomena Inoue first proclaimed his lifelong slogan "Protection of Country and Love of Truth" 護国愛理. Inoue attempted to demonstrate Buddhism's consistency with philosophical and scientific truth and its benefit to the modern Japanese nation state.
In 1888, Inoue departed on his first of three world tours. The nationalist spirit he observed in the Western imperial countries and the promulgation of the Imperial Rescript on Education (1890) after his return, gave Inoue's maxim of the Protection of Country concrete meaning. The spread of the Education Rescript as the moral foundation of the rising Japanese Empire became one of his main objectives for the rest of his life.
In his lectures at the Philosophy Academy, Inoue pioneered several academic fields. Inoue's lecture records which were published as textbooks for the Academy's distance learning program cover subjects like Psychology, Pedagogy, Religious Studies, Buddhist Philosophy and the original science Inoue called Mystery Studies 妖怪学. In a large scale project, he recorded, categorized and rationally explained every kind of folk belief and superstition he heard about in Japan. This ambitious program made him famous among his contemporaries as Doctor Specter お化け博士.
Inoue managed the Philosophy Academy as an institution that promoted the revival of Eastern scholarship. Most pioneers of modern Buddhist studies were lecturing in the Academy. Inoue interpreted his role as a lobbyist for Buddhism in the capital and worked to consolidate the position of private education with the Ministry of Education. In 1896, Inoue was the first to be awarded a Doctor of Letters by submitting a thesis to the Faculty of Literature of Tokyo Imperial University.
While Inoue was on his second world tour, the so-called Philosophy Academy Incident 哲学館事件 (1903/04) took its course. Inspectors from the Education Ministry became aware that one student received a full score in the ethics examination for answering that regicide under certain circumstances could be legitimate. The ministry threatened to close down the Academy, demanded that the responsible teacher resign and withdrew the Academy's right to grant certificates for teaching in public schools.
In the years after the Philosophy Academy Incident several factors played together which eventually led to Inoue's resignation from the Academy in 1905/06: (1) internal differences about the Academy's management, (2) estrangement from other Buddhist leaders, (3) health problems.
During the same period, Inoue started two new projects that became seminal for his late activities: the foundation of the Morality Church 修身教会 (1903) and the building of the Philosophy Hall 哲学堂 (1904).
Starting in 1890, lecture tours were important for Inoue to raise funds for the Philosophy Academy. After 1906, the fund raising served to create the Temple Garden of Philosophy around the Philosophy Hall in today's Nakano District in Tokyo. Inoue started his lecture tours during his late period in the name of the Morality Church initiative, which aimed at establishing Sunday schools in shrines and temples all over the country. In 1912, he renamed the organization into the Society for the Spread of Civic Morality 国民道徳普及会. The venue of his lectures moved away from temples into primary schools. The main objective however stayed the same, namely teaching national morals and spreading the Imperial Rescript on Education. It was Inoue's ambition to lecture literally everywhere in Japan. During his late life, he extended his radius to the new Japanese colonies in Korea, Manchuria, Hokkaidō, Sakhalin, Okinawa, Taiwan, and China.
Inoue died on June 6 1919 after giving a lecture in Dalian, China.

Influence and Evaluation
During his lifetime, Inoue was a widely read author, of whom more than ten books were translated into Chinese. His works were influential in spreading the terminology of modern East Asian humanities. Due to his prolific writing, the distance learning program of the Philosophy Academy and his lectures tours, Inoue probably had a larger audience than any other public intellectual before the First World War. He must have contributed considerably to the decline of superstition and the spread of the imperial ideology during the late Meiji period.
His prominence during his lifetime stands in stark contrast to the minimal attention paid to his work after his death. His uncritical speculative metaphysics and his ethics being based solely on imperially decreed virtues, make any future affirmative philosophical reception unlikely. Japanese Buddhist studies have passed over Inoue, because his Buddhist scholarship was not yet based on Sanskrit philology. Any philosophical discussion about the doctrinal foundations of Buddhism will nonetheless have to acknowledge Inoue's pioneering work.
Toyo University, Tokyo University's Society of Philosophy, and the Temple Garden of Philosophy are Inoue's lasting institutional heritage.
