Four changes at the break for the Reds included Natalia Ramos coming on at centre-back with Alice Bergstrom, Kirsty Maclean and Marie Höbinger also arriving from the bench.
Csillag had the first effort of the second period, latching onto a Kapocs pass, with her shot deflected just wide while the striker had another chance when Holland crossed well but neither she or Bernabe could force it home.
Another round of six substitutes arrived on the hour mark and within 10 minutes Taylor’s side had extended the lead.
Anna Josendal, operating at left-back, crossed and initially fellow substitute Ella Jones looked to be the likely beneficiary. But the ball dropped for Itamura to fire home her third goal of a positive pre-season.
The scoring was completed 10 minutes from the end when Shaw rose at the back post to head home a deep corner from Höbinger.
Ella Jones was denied a fifth by the goalkeeper’s leg within seconds of the restart but the Reds headed home to Merseyside with another solid performance under their belts.
Liverpool will continue their pre-season fixtures with a trip to face Manchester United at Carrington Training Centre on Sunday.
