Thank you all for the get well wishes and the suggestions! Really appreciate it!
After all the excitement at the Koshien we embarked on one of the first Shinkansen back to Tokyo, where we picked up our luggages at our wonderful Airbnb place and went to Mitsui Garden Hotel, where we had been before. The feeling of going back to Ginza only deepened the certainty that the trip was coming to an end, and it was bittersweet.
In Ginza we explored the neighbourhood and discovered even more wonderful places.
