Souichi is my best friend.

I moved to the mountains to escape the noise of this city.

This city is always full of noise.

My grandfather used to work in a mulberry plantation.

He likes to drive his new car.

Baking soda is a useful item for cleaning and cooking.

He has cyclothymia, and his mood changes drastically.

This forest is covered with dense trees.

He has been diagnosed with manic depression and is receiving treatment.

We had a footrace at the school sports festival.
