I didn't realise you were with Yuishinkai. We might even have met then. I was at one of Maruyama sensei's seminars in Byron Bay (possibly 2003??) I really enjoyed it, even if the new denim floor covering did dye my gi blue. I also visited Maruyama Sensei's dojo in Tokyo in 2005. I was really bummed that I couldn't train with him regularly. I live really close to his dojo as the crow flies, but the train lines are inconvenient and I wouldn't finish work in time to get there.
Yes I was there, probably there was some anonymous wrist grabbing or some such. I think that was his second visit after emerging from the temple..pretty exciting times.
I still get to Sensei's dojo(s) in Tokyo most years, I had a fellowship at Keio university some years back and get back there often, mostly its a schlep from Kanegawa which takes some time.
I think the Aunkai guys are around there somewhere as well!
