Thanks all for the info.

It looks like I am better off skip on the tour guides and go solo with my wife

Just thinking are those places that I listed doable in the timeframe I was suggesting? If I was in NRT first, which city should I visit first out of the whole lot? I was thinking leaving tokyo my last destination before going back to HKG. Say leave around 4-5 days for tokyo.

Also I was thinking flying into NRT, spend a night in Tokyo. Then either fly to Hokkaido, spend say 2-3 nights then fly back to Tokyo. Then go to Osaka, Kyoto via Shinkansen for say 3 nights. Then go back to Tokyo and spend4-5 nights and then back to HKG. Is this a good option? Or I was thinking just pass on Hokkaido and just go to Osaka,Kyoto,Mount fuji, Hot springs.

How do I obtain the visit japan pass for the flight?

Cheers,
Kenn.
