Sai
With architecture mirroring that of Modern Tokyo, Sai is governed by the Fujiwara Family, who adhere strictly to the rules laid out by their ancestors, prohibiting intermingling with outsiders, unless they're of proper brith from Wano. Rivalling the Kozuki Family, in power and influence, the Current Shogun of Wano hails from Sai, and since his rule, he's been trying to eliminate all ties of outside races and clans from Wano. Sai is a large region, containing several cities of interest. Wano's strongest dojo's are found in Sai, especially in city called Fuku.
