An attempt to decipher the message: Izumo has a sister city in the US: Santa Clara, California. The province of sister city might be the county it’s in. So that would be Santa Clara county. Maybe the blue&black branch or subdivision of Immortals has relocated there. - Glenn

Maybe I’ll go there next and check it out. Aren’t there redwoods there?
Maybe skip the California idea. See Merlin’s comment here: http://www.trueimmortals.net/?p=2255#comments
