My paternal grandfather once traveled all over Japan when he was young.

Let's go fishing.

She was as beautiful as a mermaid.

He is focused on his work.

I will work at home today.

He is a successful industrialist who has started many companies.

He showed bravery just like a strongly brave general.

There are many young fish swimming in this river.

This annual fish matures within less than a year of being born.

His hobby is making gyotaku.
