I have been reading as much as I can find online MJER lineage and teachers. I found this
http://ejmas.com/tin/2006tin/tinart_hellsten_0206.html article by Pasi Hellsten on a trip from 2003. Through it I became aware of Takeshima Sensei having been a student of Fukui Harumasa (19th MJER Soke) teaching at Kochi Budokan. I decided to look further as I was interested by what Pasi wrote about their technique being very dynamic.
Sadly the next search found this:

Strange that it may be, as I never had opportunity to meet him, I'm very saddened by his loss. I know those of you who were lucky enough to have met him personally will feel it even more so.
I don't know how many more sensei there are remaining of his generation and calibre but they are becoming more and more scarce and it really makes me feel an urgency to learn from them while we still have the option.
If you are serious about your Iai, have the resources to get yourself to japan and opportunity to learn from this generation then please take it, because once they are gone you can't get that knowledge back.
