Maestro cards not being accepted in Japan

So since April 19, Japan started to decline Maestro cards. You cannot withdraw anymore money with a card that has the Maestro logo on it.

I have a Maestro card.

I’d have been royally screwed over had I not found out this information before I left to Japan (which is in two days). Finding out, I’d been scrambling to find a way to get money while I’m in Japan, and eventually decided to just withdraw some euros in cash, and exchange it for yen in the Netherlands before I leave. Luckily, I’m able to do this tomorrow, the day before I leave.

But by god is this stressful. When will the cards work again? A week? Two weeks? A month? Please tell me, I can’t be stranded without money ;_;
