I found this hotel in Ginza,Tokyo on Booking.com and was able to make a booking 12 months in advance – The Royal Park Hotel
Ginza 6-Chome

It is 230m from Higashi-ginza Station which has a single train operating from Haneda airport.

There are no bath tubs in the 21m2 Standard double rooms and I have attached a pic of the shower.
