Nodiadau
--------

Yn swyddogol, gelwir y tri ymerawdwr olaf gan eu enw cyfnod yn Siapan. Gelwir Akihito yn *Tenno Heika* yn Siapaneeg, gan mai ef yw'r ymerawdwr sy'n rheoli, ond enw ei gyfnod yw *Heisei*. Yn Gymraeg a Saesneg ei enw personol a ddefnyddir.

Yn y gorllewin, gelwir Mutsuhito a Yoshihito yr Ymerawdwr Meiji a'r Ymerawdwr Taisho yn eu tro, ond defnyddir enw personol Hirohito.
