Looking for a Tokyo highlights tour

[rljan]

We are booked on a cruise, leaving Yokohama on April 10, 2023.  This will be our first trip to Japan.  We arrive on April 8 and have a hotel booked in Yokohama.  We would like to take a tour of Tokyo on 9 April and would welcome suggestions from those who have experience in Japan.  Spoiler alert: April 9 is Easter Sunday and I'm not sure if that will be a problem finding a tour or not.

Easter holiday is not celebrated in Japan. No problem.
