You may have to pay more than 10,000 miles though since SIN-NRT is farther than SGN-HKG.
You only have two options regarding ug'ing with miles for SIN-NRT:
5K miles if Y or B class fares
or
10K miles if you're in M or H
Here's the chart:

If they charge you more than that and you don;t get the next segment ug'ed then call UA and get it corrected. Good luck getting the SIN-NRT ug, that's a tough one.
