Born in 1840 to a wealthy farming family in Fukaya, Saitama. In 1867, he accompanied Tokugawa Akitake to the Paris Exposition, where European financial systems profoundly influenced him.
After serving in the Meiji government's Finance Ministry, he left in 1873 to head the First National Bank. Rejecting the prevailing attitude of "government above people," he devoted himself to building Japan's private sector.
He was involved in founding approximately 500 companies — including Tokyo Gas, Oji Paper, Imperial Hotel, Tokyo Stock Exchange, and Sapporo Beer — and 600 social organizations. He advocated "The Analects and the Abacus," arguing that moral principles and profit-making must go hand in hand.
He died on November 11, 1931, at age 91. In 2024, his portrait was adopted for Japan's new 10,000-yen note — a fitting tribute to the man who built modern Japan's economy.
