I understand that in some parts of Japan you will find 100V and 200V
single phase in lieu of the standard 120V or 230V. Does this apply to
three phase power as well? I have been told that Japan uses a strange
three-phase open delta; four-wire, earthed mid-point of phase.  This
gives you 200V single phase or at most two phases of 200V or 100 volt
single phase. Is anyone familiar with this system or is there a link
somewhere that explains this.

Thanks
