I have to go to Osaka in March, and then to Hong Kong (haven't been to either place).

Since this will be my first visit to Japan, I was trying to figure out what I should do if I want to spend a couple of days in Japan. I don't want a very busy itinerary, since I like to linger and enjoy a particular area, vs checking boxes.

I was either thinking of combining Osaka with Tokyo, or with Kyoto, or just doing Osaka. I will be flying in from Denver (*A flights) and thought about either flying into Osaka, or taking the train from Tokyo. After Osaka, I have to get to Hong Kong, so I don't know if that should play a role for my itinerary.
