Hiroshi Ishibashi is a Japanese businessman, the billionaire heir to Bridgestone Corporation (TYO: 5108), one of the world's largest tire and rubber companies. His wealth is multi-generational, rooted in the industrial empire founded by his grandfather, Shojiro Ishibashi, in 1931 (who pioneered the English translation of his surname for the company name, Bridge + Stone).

Ishibashi's career is defined by generational stewardship and cultural patronage. He studied in the U.S. from 1964 to 1971, gaining crucial international exposure. He later held several roles at Bridgestone, including chief industrial designer and lead corporate identity program manager in the 1980s, ensuring the global consistency of the iconic brand.
