to give u the best experience, fly with Singapore airline new A380s first class to Tokyo, with transit at Singapore.
It will set u 140k miles return, with little airport charge, so u still short of 20k miles.
Singapore air also fly their old A380s and 777-300er first class to Tokyo and Seoul, these can be your second option.
With 120k miles, you can fly to any city of japan Korea and Taiwan return with business class with any airline.
Among the top pick is Eva air, sq, Ana and japan airline.
If your want to use your miles efficient, suggest sq spontaneous escape, but need to be flexible, u only have 2 to five Weeks to book and plan before you fly.
