This is, as it sounds, a rate where you pay for the first three nights and the fourth night is free.

However, when you use this link and try to book four nights between the months of March and May, the "4th Night Free" rate listed is much cheaper:

The cheapest I found was for the end of May (May 27th to May 31st) during which time a Park Deluxe room for 2 is going for 29525 yen a night. If the fourth night is free, then the room could be had for less than $250 per night.

Unlike the regular 4th Night Free promotion, this one is a full prepayment/non refundable rate, and the rate description is a lot more vague, making it unclear whether or not the fourth night is actually zero yen, so doing this is not without risk. Let the buyer beware...
