The press conference usually begins around ~0630 GMT
This of course follows the monetary policy decision earlier here. With the yen strengthening in the aftermath of the lack of action by the BOJ, Kuroda may have a word or two to try and take some pressure off the currency so just be mindful of that possibility.
Otherwise, if he reiterates a similar message to what has been said before, it is pretty much "bend until it breaks" for the Japanese yen, that is markets pushing the yen until something changes on BOJ sentiment in the coming weeks/months.
