> Do you have any stats on apartments without baths? I know apartments with no showers exist but I haven't seen one since 2000.

I dug around a bit and I can't find anything outside of some articles with people wondering if those apartments are still worthwhile with the number of public baths going down.

I know I've seen train ads for new ones as recently as last year -- it might be worth mentioning that all of these apartments are inside the Yamanote, which explains why they don't have baths... cut everything possible to keep the rent down to something someone could normally hope to afford.
