That's a stupid metric, I don't know why they keep bringing it up. Japan is a good debtor and it's probably cheap for them to finance their debts so they could end up paying less for them than a bad debtor would for a debt worth 50% of their GDP.
Money spent on the economy stimulates growth even if it comes from loans.
I'm not an economist but probably I would probably define the ideal amount of debt a country should have is when the amount of economic growth coming from the extra money is equalled by the costs of financing said debt.
