My holiday, to see gardens, traditional steel making (for swords) etc was greatly helped by JT's super local knowledge, ability to find hotels to closely match all my needs, plus their good administration.
The Green Pass was very cost effective as I undertook all my travel in Japan by rail: it was also useful as a pre-bought ticket for local trains, thus avoiding the need to queue up at ticket offices:
The river valley journeys, eg Okayama->Matsue, & Nagoya->Takayama, were particularly beautiful, even when it rained! And in the Green Car one can see out of the front of the train!
All my expectations were met - A big "Thank you"
