I.e., this is not "entering" Japan, nor causing any issues that would disallow boarding in NRT nor arrival in HKG.

21 day quarantine in HK is already planned as required (relative is a permanent resident of HK so no issues there). No issues w/ getting the negative PCR test in the US prior to departure too.

Many thanks.
