JohnF. There is a very good reason for Oomote (which is also what the biggest database, GoGoD, uses). It is true that names such as Kori Toshio (in GoGoD and elsewhere) use a single O for OO, following usual practice in the wider world. But Oomote has a triplet: OOOmote. As the characters (and pronunciation) tell you.
