KNF has it's zoi extended there, while Hogosha don't.
Otherwise, it's a backwater region, partially colonized by a Kusari corporation, whose only connections to home space are through the independent GMG systems.
Nagano is connected to home system by a border system, with little Kusari assets present.
This is as best I can describe. Hopefully others can point out more relevant points that show the difference between the two systems.
