I'm not aware of any issue with a hotel or ryokan accepting a bag for a guest who will arrive within a few days.
Asking the takkyubin (courier) company to hold on to a bag rather than a hotel seems unnecessary to me.

Only time I ever specified a particular courier was when I wanted bags delivered to a small island, I had figured out which company was represented at the location. As I sent my bags off from Nagoya Airport, most of the takkyubin services had their own desks ther so it was straightforward to identify and use the appropriate company.
Otherwise, I just go with the service linked to the hotel I'm staying at, never ever had a problem. Hotel staff have always been aware of the takkyubin published deadlines for any desired delivery date and won't accept the request if the delivery cannot be guaranteed.
