- Japanese: 高札 (kousatsu) or 制札 (seisatsu)
Kôsatsu were signboards hung in Edo period towns to notify people of local laws, ordinances, and announcements.
In post-stations (shukuba), signboards often also listed the costs of various services within the town, including the prices for hiring porters or post-horses to carry luggage as far as the next station or river-crossing.
