Japanese culture also has a number of "ritual purity" elements, such as taking shoes from outside off in the genkan (vestibule) before stepping into the main part of a house, and ritual cleansing with water when visiting a shrine. I understand that Japan is far more economically advantaged than India, but even so, the difference in how clean things are between New York City (for example) and any major city in Japan is quite stark.
