Today, it is common to stay only one night at a hot spring, but years ago people often spent many days there, for the therapeutic benefits. Such a stay is called toji ("cure using hot mineral water").Toji regimes were measured in units of time — hito-mawari ("one cycle") was therapeutic bathing for one week and futa-mawari for two weeks, while a longer three-week stay was called mi-mawari. Shorter stays became common throughout Japan around the 18th century. When travelers began staying for as little as one night, coming not for a cure but simply for enjoyment, the new word coined for such a stay was ichi-ya toji. (Ichi-ya means "one night,"and the word toji in this case does not imply a cure.) The generally accepted pattern now, a stay for one night and part of two days, comes from that custom.
