Intest Rate/Inflation Increase? Short term vs Long term effects?

Increase Rate increase is good for a currency in the short term…

Surely if you have a longer term view you would view that increase as a a bad sign highlighting bad growth for that economy and therefore a weaker not stronger currency? e.g. UK sterling in the boom days.

It seems like everything is conflicting. e.g. Japan is really weak on 2% inflation target, low interest rates and government intervention. But surely this weakness will turn out to be strength for the currency going forward?
