Red tiles were manufactured from around the 18th century, but at that time "red" was considered a noble color, and it was only after entering Meiji period that ordinary people could use it. In Okinawa, where there are many typhoons, the seams of tiles are painted firmly in plaster to prevent them from being blown off by strong winds. It is said that Shisa on the red tile roof, which is seen in Okinawa, was made of plasterclay roof tile craftsmen and red tiles.
Ryuso was allowed only to be worn by royal and samurai during the Kingdom of ryukyu period.
