Japan Celebrity excursions your experiences please

We are sailing September this year round Japan and to Busan South Korea. We have already booked on a private tour to Kyoto . We wonder if you have experienced any excursions you could recommend and any you wouldn't.

Really looking forward to our first trip to Japan!

Looking forward to any help you can offer.

Here is our experience on Millennium's Japan and China cruise in 2015

My busan Celebrity excursion was cancelled so we did most on our own. Most ports provided shuttles to town: busan, Aomori, Sendai, Niigata, and in Nagasaki we took the tram.

At the end of the cruise we took the 5 hour Celebrity Tokyo tour with Narita drop off at 4 pm it was excellent.
