Seiroku Honda

Seiroku Honda proved through his own life that disciplined saving and patient investing can turn a modest salary into extraordinary wealth. Born in 1866 to a farming family in Saitama, he lost his father young and worked his way into the Tokyo School of Forestry. After studying advanced forestry at the University of Munich, he became a professor at the Imperial University of Tokyo for over 25 years.

The cornerstone of his method was the quarter-salary rule: set aside exactly 25% of every paycheck before spending anything, and live on the rest. All supplementary income went straight into savings. Simple in concept, it demanded iron discipline. Honda channeled these funds into stocks and real estate, following a contrarian principle: sell in booms, buy in busts. He made well-timed moves around the post-Russo-Japanese War surge and the 1923 Great Kanto Earthquake crash. His forestry expertise gave him a decisive edge in timberland investments, where he acquired undervalued forests and managed them for long-term value.

Upon mandatory retirement in 1927, Honda donated virtually his entire estate to educational institutions and public works, anticipating modern philanthropy by decades. As a forestry scientist, he designed Hibiya Park, the Meiji Shrine forest, and other iconic green spaces. The Meiji Shrine forest was planned around centuries-long ecological succession, reflecting his investment philosophy of long-horizon thinking. His book My Confession of Wealth remains in print and widely read. He died in 1952, aged 85.
