My guess.... and this is a total guess...
Maybe if the form is completed on online (and submitted online) and the additional items the immigration rep/qiosk request (photo, hotel name etc) are also given online, you will be able to totally bypass immigration (i.e. the govt of JA will have already vetted your arrival and electronically stamped for passport for a 3 month stay). Then you could head right to baggage claim and customs.

I think this is what some other countries have tried to do... reduce the number of people who have to be physically processed by immigration by doing it online ahead of time.
