Am I eligible to utilize the 144 hour visa free transit when taking a cruise embarking in Shanghai?

I am planning a seven night cruise with my husband and adult children that embarks in Shanghai and sails to the following Japanese ports ( Koyto, Kobe, and Tokyo) before disembarking in Shanghai. We are flying from the United States and would like to arrive in Shanghai three days before the cruise to sightsee in Shanghai. When the ship disembarks in Shanghai, we plan to fly back to the United States the same day of disembarkation. Does this itinerary qualify for the 144 hour visa free transit? If allowable, how do I acquire this 144 hour visa free transit and what documentation is required? Where and to whom is this documentation shown?
