Already booked for a trip in September (all points and miles!) to Geneva-Strasbourg and Paris but have given some thought to scrapping it to go to Japan.

We can be away up to ten or eleven days. Figuring three days for travel, that means up to 8 days.

How many days do we need to do Tokyo right? What one other city would make sense and not be too hard to include and how many days should we spend there?

I greatly appreciate any and all advice and insights!

Happy New Year!
