Big birthday coming up and I want to go to Japan. It would be me, DH, DS15 and DS12. I want to go to Tokyo but are there places in Tokyo to get away from all the busyness a bit. We lived retreating to Central Park in New York for a bit of a rest before heading back out to see the sights etc. Is there something similar in Tokyo? Also is there anywhere close enough to Tokyo to visit in a day where we can see traditional temples and forests and mountains etc or are we best doing a twin centre holiday?
