Any hotels in Chitose with pay by hour?

I wonder if there are any hotels at Chitose or at Sapporo which charges by the hour?

Because I would like to have a couple of hours to sleep after landing at Chitose early in the morning.

And most hotels in Japan instead only allows check-in at 3pm, which I don't think I can wait until 3pm.

I can think of 2 options.

1) love hotels. They are specifically made to allow stay for a few hours
2) Relax area of the onsen inside the airport (note that you need to leave at 9:00 am) http://www.new-chitose-airport.jp/en/spend/relax/spa/

If there is any manga café, they go by the hour, some also include food and drink.

Alternatively, book something really cheap for the previous night and let them know you are turning up the following morning due to flight times.
