Did you know that nearly 98% of adoptions in Japan involve adults rather than children?
Even more surprising, most adoptees are men in their 20s and 30s.
The reason is deeply tied to business and family legacy. When a family-owned company lacks a suitable male successor, the family may adopt a talented young man to inherit the business and continue the family name. This tradition is known as Mukoyōshi (adopted son-in-law), and the adopted heir is often married to the family's daughter as part of the arrangement.
The practice is so common in Japan that specialized matchmaking services exist solely to connect business families with capable young men willing to become adopted heirs.
One famous example is Osamu Suzuki, the leader who transformed Suzuki into a global automotive giant. He was not born into the Suzuki family—his birth name was Osamu Matsuda. He became the fourth adopted heir in a continuous line of successors who led the company.
In Japan, adoption isn't just about family—it's also a strategy for preserving businesses, traditions, and legacies across generations.
