Shoryudo Bus Pass Question

Evening all. I'm a bit confused about the eligibility requirements for the Shoryudo pass (thinking of the 5-day wide, though I believe all have the same eligibility rules). Japan Guide says temporary visitors only, but the official website says "All holders of a residence card or non-Japanese passport will be eligible to use the SHORYUDO Bus Pass". Now this doesn't necessarily make sense - a foreign residence card holder will by definition have a non-Japanese passport. What's the deal for zairyou card holders - yes or no, anyone know? Thanks in advance.

It seems that the pass' conditions changed recently, and it is now also possible for foreign residents of Japan to use the pass. The Japan Guide page was updated accordingly:

Thank you!
