How to access the Chisun Inn Hommachi?

I booked the Chisun inn osaka Hommachi and tried to check how to access from Kanzai airport by Hyperdia.
It says in some web. to take Nankai line to Namba and change to take subway to shinsaibashi stn. I checked from Hyperdia and they took us to change train at Umeda and then to shinsaibashi.

Why do they not inform to take direct trains to namba by Nankai which is closer?

Where can I find how to access this hotel clearly? Please advise. Thank you.

Without knowing the settings/times you used on Hyperdia it is impossible to say why you got such results. I have tried to get those results, but it has not been possible.

Very simply, take the Nankai railway to Namba and transfer to the Midosuji subway line to Shinsaibashi.

The fastest way from Kansai Airp. is riding the Nankai Rapit train to Namba and change there to the midosuji subway getting off at Shinsaibashi St. or Hommachi St.

It might be easier to change trains in Tengachaya and get off at Nagahoribashi.
Compared to Namba Stations, Tengachaya Stations of Nankai and Osaka Subway are located closer to each other.

In Nagahoribashi Station, from the platform's end in the direction of your train you can go upstairs to the north concourse, pass through the ticket gate and go out from Exit 2-B.

The airport station is called "Kansai Airport," not "Kanzai airport."
Have you designated this station as "KANSAI AIRPORT" for Hyperdia?
As to route-finding tools like Hyperdia, it is not a human but a computer who search for routes; so the result is not always the best route for every traveler.

Have nice trip!

Thank you very much.
