Takeru is my best friend.

Due to yesterday's heavy rain, a mudslide occurred from the mountain.

He was exiled for political reasons.

He was demoted and exiled because his misconduct was discovered.

Be careful of the riptide and swim safely.

Virga is floating in the sky, creating an atmosphere that seems like it's going to rain.

He is a person who follows his own path, and the phrase 'a big fish does not swim into a small stream' fits him perfectly.
