By all accounts, Hiroshi Yamauchi, longtime Nintendo president, was a difficult man to deal with. The man responsible for turning Nintendo into a video game empire was also prone to fits of temper. While his obstinacy and dedication to the business helped build an empire, it often put a strain on his relationship with his family. His frequent business trips and tendency to seek "companionship" from women other than his wife were particularly irritating to his daughter, Yoko. At an early age, Yoko decided that, should she ever marry, her husband would be nothing like her father.
During her senior year of college, Yoko met Minoru Arakawa at a high-society ball put on by Kyoto's old monied families, of which Minoru was a member. They quickly fell in love and were married. In a foreshadowing of things to come, Yamauchi eventually took a liking to his son-in-law and came to trust his judgment.
While the first year of their marriage was idyllic, things got more stressful when they moved from Japan to Canada, where Minoru was overseeing one of his company's real estate ventures. Life in a foreign country, away from friends and extended family was hard, especially after they had kids. However, Yoko and Minoru had resolved to make it on their own, without any financial help from their considerably wealthy families. This would change in 1980.
While I doubt there were any mystical islands, plane crashes, or cryptic numbers involved in the Arakawas' story, I couldn't help but be reminded of Woo-Jung Paik (Sun's father) from Lost. What is it about titans of industry and trying to circumvent their daughters' wishes by bringing their son-in-laws into their cut-throat family businesses?
Thankfully for Yoko and Minoru Arakawa, life seems to have turned out better for them than it did for Jin and Sun. After leading Nintendo of America for 22 years, Minoru retired in 2002. Presumably, he is still living in our time line and has yet to encounter any smoke monster-related difficulties.
