Ok, I'm in Mitaka-shi now and the water (like most areas of Tokyo) has an aftertaste that makes me feel like I'm drinking liquefied prostate cancer. Now, back in Sacramento where the water wells are contaminated with thyroid issue causing jet fuel, this is a bit ironic, but I do wonder about water standards here!
Seriously, does anyone know much about what the water standards are for Japan? If it has this bad of taste it can't be that good. I'm sure I'm not drinking minamata-disease level stuff, but I do wonder what is done with the water here if it still tastes this awful...
