If the Holy Kingdom Wall is 100 km long, that makes the overall map about the size of Spain in land area, maybe throw in Portugal. Alternatively, one can consider that the map scale should be to small to fit Japan on it without distortion/cropping.

Given the presence of the Azerlisia Mountains and other ranges cutting up the available watersheds and basins, along with extensive underground caverns, it's not too hard to imagine that rivers tend to be relatively small and winding.
