Hiru no Sento Zake S01 E01 "Tsurunoyu Bath, Followed By Fried Liver"

Takayuki Utsumi (Shigeyuki Totsugi), yet again with the least sales this month, heads out searching for new clients... only to find the chimney of Tsurunoyu Bath, a bath house found in Koiwa, Tokyo. He is still working, but is tempted. And in bright daylight, on a weekday, he flips through the entrance curtains, and into the bath house he goes.
