日光街道
Since the Edo period, Kichinyado (木賃宿, a type of cheap lodging house that does not serve meals) have been located along the sides of the Ōshū Kaidō and the Nikkō Kaidō routes (two of the five main Edo period routes). To this day, there are many of these simple lodging establishments in areas where day laborers assemble. Throughout Japan, these lodging establishments are called “doya"(). Prior to 1966, the address of this area was Taito-Ward, Asakusa, Sanya 1~4 Chome, but due to a government program enforcing the renaming of displayed address across Japan, the name “Sanya” faded away.
