Pretty Simple. And Prabhat, you give fictional places like these.

X is a fictional region, meaning "castle palace" and "lattice shaped palace". This region is connected to the western part of the region in the original series, Y. X is geographically similar to Kansai, eastern Shikoku and western Tokai regions of Japan. Y represents eastern Tokai. All cities in Y are named after colors while the names of the cities in X are either plant themed or colors. The cities of X are old fashioned cities reminiscent of Nara and Kyoto and modern commercial city reminiscent of Osaka.
