Higahara Prefecture

The Higahara Prefecture (ひがはらけんか, Higahara Kenka), known colloquially as simply Higahara (ひがはら, lit. Evil Prairie) is a province located somewhere in northern Japan that is tucked away from the world. That is, Higahara is surrounded by a special barrier, set up by locals long ago, that effectively hides them from the world. This stretch of land cannot be found by GPS or any sort of man-made technology. Also, entry into this guarded location is only possible by uttering the key phrase, which is confidential. Higahara is home to the "spiritually aware" and a haven to the same. In addition, the people are friendly to select Shinigami, those they believe to be honest and trustworthy. Kai Nageki passed through here a few times during his travels.

Trivia

 * While entry into the province is closely guarded, residents normally travel in and out, enjoying life in the normal world as well. One wouldn't be able to tell the difference between a Higahara resident and a Karakura resident if tasked to.
 * Higahara is known as somewhere the "odd and gifted" find peace, love, and security.
