If wewe could mash two countries together; which countries would wewe combine?

Turkey my country and Japan, I wouldn't mind living surrounded kwa sakura trees and traditional houses.

Certainly Greece and Japan. Giving an easier way to satisfy Weebing needs aside, these two Countries share various similarities actually, especially Geographical ones, that would fit right in with each other just as contrasts that would further compliment them aesthetically. Agreed with Jet regarding Sakura Trees for example. Mixing them in with all the Greenery and witnessing them blossom across Neighborhoods would be a sight to behold. Shrines being spread out among the Local Villages, Temples atop Mountains, larger Festivities taking place in the streets, Cuisines coexisting (especially when it comes to Fish), the Traditional element getting zaidi vibrant with the mash up of Architecturing, etc.

I'd also say the same for China although the similarities greatly outnumber the contrasts between it and Greece in this case. Still would offer some very beautiful opportunities and displays !!!!
