It depends on what kind of activities you prefer.
Looking around for tradittional stuff, new high tech stuff, eating, night life etc.etc....
I am a Japanese and I like travelling myself, so I can always give you information and advise.

Send me a PM anytime. I can help you with it
Hope you have a wonderful time in Japan!

I arrived safely,

went to an Onsen near Kobe, met yakuza, ate like crazy...
I spent most of my time sleeping today though. jet lag...

48 hours.....

Glad to hear you made it!

Honestly, didn't get a whole lot from this except you are there and jet lagged.
Have fun.
