This restaurant offers an all-you-can-eat service on weekends.

Throwing away food scraps is a waste of food.

Where does your younger sister live?

She is my sworn younger sister, and we are always together.

My younger paternal half sister is very smart.

My sister-in-law is a very kind person.

Where is your sister?

We respect Japanese culture.

We are going on a trip tomorrow.

When I first met her, I introduced myself saying, 'I am Japanese.'
