I'm not recommending hyperinflation. Countries like Japan and the USA with their current levels of debt will someday have to inflate or they will have to renounce the debt officially. That is a mathematical certainty. But that day is a long way off. Low inflation is better. If exchange rates are out of balance, such as in Japan in 2010, inflation in the prices of only imports should be sufficient and that should be moderate at worst. In any case it's nothing to worry about now.
