I must have listed 'Japan' as an interest when I sarted my Vox blog, because the sidebar ads are always for Japanese things. Just now there was an ad for traditional Japanese loincloths. I don't think they're really useful to me in batches smaller than 50 and without (a) a portable Shinto shrine, (b) a bunch of guys to carry it and (c) enough sake to make them willing to do so.
