Indoor Signs

The indoor display is a sign for indoor / indoor use such as pictograms and messages. “Osu”, “Hiku”, “Vacancy”, “In use”, etc. are typical of the door display. The toilet displays range from “Western” and “Japanese” to prompting the user to flush the water after use. I often see it on stairs, floors with steps, and places with slippery floors. It also includes stickers such as “Caution for handling” and “Caution for aliens”, which are very useful goods for creating an easy-to-understand and safe environment.
