>>32785815>I - Accordion CityBased on Okayama Prefecture. Accordion City is rocky, but that brings a great view of both the ocean and the forest. Make sure to check out the Safari Zone and the Ice Gym!
>J - Celesta CityBased on Tottori Prefecture. It's one of the more exotic locations, being a town settled on a hill between sand dunes and grassland. It has a Grass Gym.
>K - ??? IslandBased on Tesshima Island. It's a comparatively modern and practical town, having a circular design that is easy to traverse. Its Fire Gym is on the left side, near the top.
>L - ??? IslandBased on Naoshima Island. This isle doesn't have a Poké Mart or a Gym, but its white, glass-and-glaze architecture is sure to leave an impression.
>a - Forest CaveBased on Iya Valley. It's a vegetated cave crawling with Bug-type Pokémon. Its bottom floor requires Cut and must be accessed from the outside.
>b - Capsule TunnelBased on Akiyoshido Cave, the largest and longest cave in Japan. Its top floor is simple, but beyond the fissures and boulders lies a corridor maze.
>c - GraveyardNot based on anything. Serves as the region's "burial ground".
>d - Safari Zone>e - ??? CanyonBased on the Tottori Sand Dunes.
>f - ??? (some kind of ruins)Requires Surf to get to. Never put much thought into this, but I wanted to continue the tradition of an area near the player's hometown being accessible only by Surf.
>g - Mt. SpecterBased on Mt. Ishizuchi, the highest mountain in both Shikoku and Chugoku.
>h - Altering CaveNobody knows this mysterious gift!
>i - Nieto OceanBased on the Sea of Japan. It's an expansive final dungeon on water (you can buy a Surfboard item if you don't have a Surf user), and on an island based on Okinashima, there is the Pokémon League. (sry4cliche)
Progression would be A > B > A > C > a > D > E > a > F > G > H > c > H > b > I > e > J > K > L > K > F > i
d, f, g, and h are all optional
From F to I, it would be more nonlinear, but this is the "canon" path
