Airport; Human Factors
Landed RJAA.  [Received our gate assignment as we taxied] off 16R.  Given ground clearance to taxi B hold short S4.  Nighttime taxi.  Then clearance right [left] on S4 left on Charlie.  the right [left] turn onto S4 was done and we then had trouble deciphering where C was because S4 was a 110 [70] degree right [left] turn and then C was another immediate 90 degree left turn; however Taxiway C was not marked due to the new construction I believe.  We were taxiing at about 4 or 5 miles an hour and then saw a sign for C to our left but this was not visible until PASSING Charlie.  Extremely poor signage.  I believe this should be marked as a hotspot due to the poor signage and/or improved signage provided.  We notified ground that we inadvertently passed C due to the poor signage and Ground then cleared us straight on S4 and left on R to the gate.  It was not an issue; there were no other aircraft in the area and there were no saftey issues.  Ground did not have an issue with it.
B777 First Officer reports a taxiway incursion at RJAA while attempting to comply with taxi instructions to the gate after landing. A complicated taxi route; poor signage and construction were cited as factors.
