Nice Mario, Japan was my college graduation present, and we did a tour of sorts that sounds like yours, the giant buddha, feeding the reindeer them crackers for like 300 Yen, doing a tea ceremony, seeing 2000 year old bonsai trees, and such. Did you go to Kyoto and do a Geisha tour? Or go to Nara and see the female divers dive for Mikimoto pearls?
Glad you had a blast, Japan is awesome indeed. 14hr flight, not so much but worth it once youre there and get over the lag/time difference.
P.S. - The fact that they have alcohol in vending machines blew my mind. I would walk the streets of Tokyo at midnight with a glass of Geikikan sake I just got from a vending machine.
Oh and did you play pachinko?
