Why isn't the direct route between Nagoya to Osaka covered by the Takayama-Hokuriku Area Tourist Pass?
It's possible to go from Nagoya to Osaka using the Takayama-Hokuriku Area Tourist Pass, but only by going via Kanazawa, rather than directly.
As someone unfamiliar to the economics or the politics of JR, why isn't it possible to travel directly (apart from by buying your own ticket)?
Does this kind of weird rule apply in other scenarios with non-country-wide JR passes?
