i know this isn't particularly political, but the japan forums look a little quiet and this is something that i - as someone who spent most of my time growing up doing a martial art - feel would be a bit sad to see go.
basically the Kodansha Publishing Co want to knock down the one remaining old kendo dojo from the Taisho period (c. 1910s - not very old, but quite an important period of history) and a load of people don't want them to do it. pretty worthy cause - not a lot of this old stuff left it seems...
