The Japanese pronoun 'こちら (こちら)' is a polite way to refer to 'this' or 'this one'. It is often used to indicate something close to the speaker, whether it be a person, place, or thing. It can also be used to refer to oneself or one's side in a formal context. For example: This is my friend「こちらは私の友達です」(こちらはわたしのともだちです). This way, please「こちらへどうぞ」(こちらへどうぞ). It is important to note that 'こちら' is more formal and polite than 'これ (これ)', which also means 'this'.
