This route is unnumbered for now, because it's technically the last Nihon Route (numbered 23 in-prototype) and I don't know how to number it yet. It's easily find/replaced once we're sure, anyway.
Wild data uses the prototype's plus a couple edits, levels are kept low as you're actually entering here.
It's official: Nihon is connected to Johto and Kanto now!
This adds the Pokemon Centre infrastructure for Nihon and Silent Hills's one.
For all future Nihon Pokemon Centres, they must refer to the 2F one for the warp, and the map blocks for 1Fs should use the Nihon variant.
Kanto will follow suit (eventually). The aim is to make a more immersive region structure.
