According to the Japanese Government and Business Insider 98% of adoptions in Japan are employers adopting their employees aged between 20-30 years old. This is a trend that dates back hundreds of years.

Japan puts family first in everything from politics to business which means money and power is passed through lineage. Because of this before someone can help lead or take over a business many times they must first be adopted to become apart of the family. So that next job promotion may involve more than just a pay increase and change in title.

Japan is one of the few countries who many times the man will change his last name during marriage because of a tradition called mukoyōshi. This is seen mostly with wealthy families who don't have a son to inherit the family's business.

If you think this is just the smaller lesser known companies think again! Suzuki and Toyota are "Family Owned" businesses with adopted sons running the show.
