A big Thank You is due to Kaoru at JTC for making all our hotel arrangements, and suggesting an itinerary that worked well. Also for providing Japanese translations of phrases you don't find in the guidebooks such as "can we leave our suitcases in your hotel until we return tomorrow afternoon".
Particular highlights for us were staying overnight in a Monastery in Koya-San, travelling by Bullet Train, and staying in a Capsule Hotel in Shinjuku. Not to mention the great food, sushi etc!
JTC kept us well informed of progress in making bookings, and we have no hesitation in recommending them for your trip to Japan.
