TOKYO (Reuters) - The investment firm managing nearly $1.5 billion of assets for members of Nintendo's founding family is willing to play a long game when it comes to portfolio companies and can wait more than a decade to see a turnaround, a top executive said.

That timeline helps explain why Yamauchi-No.10 Family Office shows no sign of relenting nearly a year into its quest to take marine construction firm Toyo Construction Co private, a takeover battle that could see a critical turn at an annual shareholder meeting in June.
