As Guy Betsy wrote, we can get refund tax already paid.
In my experience, ex-NRT DONEWC3 was re-issued which decreased total number of segments.
I got MCO of about 20,000 JPY.
I made refund procedure at NRT ticket counter after completion of trip.
After this procedure, refund to my credit card acount took approx 3 months.
