Sharp-minded and quick to act, he propped up the failing family business and was trading lumber across the Kanto region by his teens. Anticipating the opening of Yokohama, he made his name in real estate and timber. But in the turbulent late-shogunate years he was implicated in an incident and imprisoned — and prison became the turning point that made him an oracle. ### The I Ching in Prison (1861–1866) In his cell he is said to have read nothing but the Book of Changes. He cast hexagrams daily against his own situation, and answered the questions of fellow prisoners with uncanny accuracy. When he was released he carried out a thick sheaf of recorded cases — the seed of the later Takashima Ekidan. ### Industrialist and Oracle (1867–1890) After the Meiji Restoration, Tozan based himself in Yokohama, where he was deeply involved in building the foreign settlement, acquiring land for the railways, and founding the gas company. He is still called "the father of Yokohama". At the same time, statesmen of the Meiji oligarchy — Ito Hirobumi, Okuma Shigenobu, Inoue Kaoru, Yamagata Aritomo — are recorded as consulting him before major decisions on diplomacy, war and finance. ### Late Years and Writings (1891–1914) In old age he retreated to Hakone, teaching the Yi to visitors from home and abroad. He published the main Ekidan, sequels and commentaries, recording several hundred cases in all. He died in 1914 at the age of eighty-three. Almanacs and books bearing his name continued to circulate widely, and "Takashima" became a byword in Japanese popular divination. ## The Method of the Takashima Ekidan ### Casting — The Full Yarrow Stalk Rite Tozan insisted throughout his life on the orthodox rite of dividing fifty yarrow stalks. Quicker methods were used for trivial questions, but on important matters he always performed the full rite, taking close to an hour for a single hexagram. ### Reading — Classics in Conversation with the Times In interpretation he drew on Wang Bi, Cheng Yi, Zhu Xi and the great commentators, while weighing the politics, markets and character of the questioner. He never absolutized the text; he drew the meaning out of the moment. He stressed especially the image (xiang) and the changing lines, conjuring concrete scenes and people from the trigrams — observers said it was "like looking at a painting." ### Judgment — A Three-Part Structure His written readings characteristically have three parts: the Hexagram Text, the Line Text, and the Overall Judgment. This app's AI reading inherits that same shape. ## Notable Cases from the Takashima Ekidan All cases below are recorded in the 1893 published English translation of the Takashima Ekidan (public domain). ### Divining His Own Fate in Prison (1861) Imprisoned in 1859, Tozan found a volume of the Book of Changes left in his cell and studied it for three years. In 1861 he made paper ropes in place of yarrow stalks and cast his own fate, obtaining Hexagram 3 changing to 60, line 2 — reading ten years to the resolution of his difficulty, and water to be waded. He records that he was banished to the island of Tsukuda-jima two years later, released in 1865, and in 1870 began his four enterprises: mail steamers, railways, gas-lighting and a school. ### The Franco-Prussian War (1870) Mr. T. Masuda, having wagered with an Englishman on a French victory, asked Tozan to secure the win. Tozan obtained Hexagram 3 changing to 8, line 1, and told him France would be defeated, the Emperor would submit, France would become a republic, and a traitor within would be effective. Masuda replied that such reasoning on the diagrams "is not worth believing". ### Count Itō's Mission to China (1885) As Count Itō sailed from Yokohama on 28 February 1885 to negotiate with China over the Korean affair, Tozan obtained Hexagram 1 changing to 14, line 5: "The dragon has flown up into the heaven. Advantageous to see great men." He read that both men would set aside small matters for large ones and seek a peaceful result, and sent the written divination on to Tientsin. ### England and Russia over Afghanistan (1885) With the Anglo-Russian boundary dispute looking like the opening of a war, Tozan cast on 8 May 1885 and obtained Hexagram 33 (Retreat), line 6: "Retreats at a bound; advantageous in every way." Weighing England's navy, small army and Indian troops against landlocked Afghanistan, he concluded she would not engage, and read that Russia could not move in force until her railway across the desert was complete. ### The Saga Rebellion (1874) When rebellion arose at Saga in 1874, two officers asked Tozan to divine the coming subjugation. He obtained Hexagram 30 changing to 55, line 6, reading doubled fire as a thing that flares suddenly and passes quickly: strike the leader, spare the followers, and the rising would be put down within thirty days. "After less than a four week's interval, the rebel was greatly defeated, and its leaders were all captured." ### A Police Officer's Debt (—) A police officer, 13,000 yen in debt from educating the relatives of a comrade who died in the Restoration, came sick with worry. Tozan drew Hexagram 60 (Moderation), line 2 — a bank holding water, which must be given outlets or burst — and told him it was unlucky not to speak: go to the creditor. He set out a plan clearing the debt in about eleven years, and told him to limit his worry to one hour a day. Days later the officer wrote that the worry had dispersed. ## A Living Tradition The several hundred cases Tozan left show that the Yi Jing is not a dusty commentary tradition but a living practice that engages with people and their times. This app stands in that lineage. By bridging classical text and modern AI, we aim to give the Changes a fair hearing on contemporary questions — as another angle of light, not a verdict. Divination does not replace your decision. Use it as a cultural instrument: to settle the mind, sharpen the question, and see your situation in a different frame.
