In Japan, one of our teachers did refer to the solar plexus as suigetsu, so I'm glad it was brought up in this column. I wasn't sure if I had remembered correctly. I'm finding these columns a fascinating way to continue my education. Thanks, everyone.
I found a few links about that here one of them http://www.shitoryu.co.uk/index.php?...=59&Itemid=136
Maybe that will help you Niall to find something more about suigetsu=solar plexus.
