Mr. Machi is my best friend.

I work in Shibuya Machi, Tokyo.

The population of this town is rapidly increasing.

My house is near the mountains.

He works as a professional exterminator.

He called me back immediately after he hung up the phone.

He has expert knowledge.

He is studying computer science at a specialized school.

He is a specialist fool, with no interest in anything outside his field.

He couldn't say anything about issues outside of his field of expertise.
