A Philippine passport holder and a Japan long term resident visa holder want to transit in Shanghai

I currently live in Okayama and had planned out a trip to Vietnam for the holidays.
I've booked my flight 4 months ago and received full details of my transit thru Shanghai on December 23rd of 2014.
I went to Thailand last August and had a transit in Shanghai which I did not have any problems with.
This time the ticketing agency just notified me today that there is going to have a slight change with the transit, instead of 6 hours they changed it to 36 hours due to "an operational schedule change airline has made". I do not want to spend the first 48 hours of my vacation in the Airport, And I know I need to apply for a day permit for me to enter the municipality of Shanghai but with the very short notice and my work schedule I worry that I wont be able to go to Osaka and apply for one.
Are there any other way for me to avail a day pass in Shanghai?
