That's called uncovered interest rate arbitrage and it's a textbook strategy. You're forgetting to account for inflation differentials and exchange rate movements though.

That happens a lot. But there are usury laws in America when you are a small time lender. You have to pay a pretty high fee to lend commercially out and then the risk on those loans are pretty steep.

There are also tarrifs for taking foreign currency on loan from one country to another, especially into America.

Your best bet would be to get a couple million from Japan, and hope the US dollar stays strong. If the dollar dips, then you will end up owing japan more money because, well, your debt in america is a constant rate.

Good luck getting a loan in Japan, their process for commercial lending takes longer than US.
