I saw on the TV news that a big cruise ship from 'Star Cruises’ called Superstar Virgo began a cruise from Manila on 19 March 2017 . A couple of thousand cruisers left Manila for a week long cruise headed for Laoag, Kaohsiung, Hong Kong then returning to Manila.
I'd also be very interested in taking a similar cruise from Manila. Especially if the itinerary would include Japan, china or Korea.

Seems like a great idea and I do hope it's be a big success with more cruises to come.
I love cruise holidays.
