Kararagi City State (カララギ都市国家), usually referred to as Kararagi (カララギ), is a country located to the west of Lugnica.
Kararagi is similar to Japan in various ways, such as speaking a Kansai dialect, having an architectural style known as Wafuu, and a food similar to okonomiyaki known as daisukiyaki.
Based on the official name of Kararagi given by Julius, it can be inferred that the country is a city state. However, it's unknown whether it is only one city state or includes a group of city states.
Kararagi was founded by a man named Hoshin of the Wilderness (荒地のホーシン Arechi no Hooshin), a man speculated to be from the same world as Subaru and Al. He introduced many things similar to Japanese culture to the country.
