Go-an

is the second Noble Phantasm of Sen-no-Rikyu. It is a portable teahouse capable of moving across the entirety of New Yamataikoku and deploying itself in any given area and requires a significant amount of Magical Energy to operate. 
As it is a Conceptual Noble Phantasm in nature, the teahouse runs on things that Sen-no-Rikyu herself desires and thus money is the most adequate form to power it due to the merchant being perpetually broke.
While Toyotomi Hideyoshi possesses a portable golden teahouse of his own, his is incapable of flight and was a prototype of this Noble Phantasm specially created by Rikyu herself for him.Fate/Grand Order - THE Great Tea Ceremony Battle GUDAGUDA New Yamataikoku, The Man Who Returned from Hell: First Cup: Let's GO to the Other World!Fate/Grand Order - THE Great Tea Ceremony Battle GUDAGUDA New Yamataikoku, The Man Who Returned from Hell: Second Cup: Standby Cha-no-yu!
