formal rule or instruction
Use verb dictionary or ない forms + 〜こと in notices and rules to require or prohibit an action.
How it works

Look at the shelter notice. What do these sentences ending in 「こと」 ask readers to do?

A verb in dictionary form + こと requires an action. The notice asks people to write down their names on arrival.

A verb in ない form + こと prohibits an action. The rule in the picture tells everyone to keep away from the danger area.

Here, 「こと」 gives an instruction or order. Readers must follow the rule; it is more than just a suggestion.

This sentence ending is common in notices, rules, and operating instructions. Its tone is concise and formal.
