NEWYEAR,
According to Parc, from 1 Apr, all selection candidates pay for their accommodation in Japan and their ground transportation. The air fare is reimbursed, as has always been the case and, from what I've heard, nobody has ever had any issues getting the money back from Parc (and you'd certainly have heard about it if that was the case). They are up-front with these matters and abide by them because, at the very least, their reputation is on the line and, with that, their business.
