Hōshi is a traditional Japanese inn called a Ryokan. It’s also the oldest hotel in the world that’s still in operation, having opened in the year 717. Interestingly, it’s been operated by the same family for the entire time – almost 1300 years. Apparently family businesses are quite commonplace in Japan:
It should be noted that Japan has a tradition of adopting adult heirs if it seems like there is nobody in the family that would be suitable/wanting to run the family business. Over 90% of adoptions in japan are of adult males in their 20s and 30s, and japan has one of the highest adoption rates in the world.
Because of this family businesses in japan are more successful than in other countries, which tend to die out due to blood lines or become other kinds of businesses.
Suzuki, Toyota, Kikkoman, and Canon are all family businesses. The current head of Suzuki was adopted, and the heir that will replace him will also be adopted.
