I'm not sure about this, but it is within a short walking distance from Osaka's main rail station, which we used to take off to Hiroshima and Miyajima on a day trip via the Shinkansen "Bullet" Train. We had arranged a guide though for those venues. Because of the close proximity of Shin-Osaka station - an absolute transport hub - I imagine accessing day tour pick ups at the hotel would not be a problem. The hotel will certainly provide guidance on this matter

When I booked a tour to Kyoto, the pick up was at a hotel in the train station. I was more central. You'll have to ask the Mt Fuji tour vendor where they will pick up from.

It seem that you must be OＫ.

You can get Airport Bus from KANSAI Airport ground floor (Arrival Floor) to OSAKA Station directly. This is most easy choice and economy price. Bus will be departed every 20 min. except late night. This hotel is just beside of Osaka Station. so that you can take JR line to got o Shin-Osaka Station. only one stop from Osaka station. But local people not to use Shinkansen between Shin Osaka to Kyoto. Because too short to use super express. and price is almost double. You can take JR Kyoto Line from OSAKA Station. This is local line but only 30 min. to Kyoto directly.

Look for Hearton Hotel Nishi Umeda on Google maps. Up and to the right of the hotel you will see mont-bell ALBi Osaka Station shop. Bring that to the centre of the map, and zoom in. At the bottom left of the station, Sakurabashi Exit / Entrance will appear after 3 or 4 zooms. That is your exit. If it is not too late at night, there will be a walkway/shortcut to the hotel. Eki Bacon is near the entrance to the walkway.At the other end, you will see almost straight ahead Hearton Hotel looming, about 40m away. If the walkway is shut, you will have to follow the street to the left, then first right, then first right again. Look up and you will see the Hearton sign lit up. Then first left and you will be at the entrance. Good luck.
