Yes. It’s no proplem. I saw lots of luggages were placed nearby reception desk.

Although a late reply, I did not see anyone smoking in the hotel. However, just outside around a quiet corner, there was a smoker. If yo are sensitive to smoke, you will smell it. This strip has smoking designated areas including under cover at the undercroft to the station across the road. While Japan is trying to make a cleaner- smoke free environment, this means that smokers can find places to smoke outside and the smoke then wafts n through vents etc.

The double room had a small open closet with an actual rack for hanging

In the hotel , ihadnot seen any laundry machines, but I think you can find easily in the area nearby.
