I've investigated this brand in the past and found that they appear to be using an unknown coordinate system, possibly a deliberately obscured one as I think I tried all the usual CRS' particularly those local to Japan. It's worth having another look to see whether they've changed the CRS, or we can figure out the CRS they are using.

WGS 84 multiplied by 3600 is a good (but not good enough) approximation. I tested stores next to Tokyo Shinjuku, Nagasaki, and Sapporo train stations.
