Masayoshi Son, the founder and CEO of SoftBank Group Corp., is rich. And his telecom and technology company has grown into a giant.

But the 58-year-old insists that his Fukuoka SoftBank Hawks baseball team doesn't rely on its parent company's financial power to acquire star players.

Son said that, unlike some other teams whose debts are absorbed by their parent companies, the Pacific League ballclub has made an effort to earn its own money through its baseball activities.
