There are also original Japanese Christmas hymns and carols, some of which are sung in English in the United States (several denominations' hymnals include "Hitsuji wa nemureri" = "Sheep fast asleep", and at least one, the Presbyterian, contains "Kurisumasu" = "Joyful Christmas Day is here"); the Epiphany hymn "Mabune no naka ni" (several English translations, including "In a lowly manger born") is also usable for Christmas. And there are Japanese (and at least one Okinawan) Christmas hymns and carols in the Japanese hymnals that have not yet made it into English, but look worth trying.
