We participated in an arm wrestling tournament yesterday.

I saw a sumo wrestler walking down the street.

A grand sumo wrestling match is a splendid combination of strength and technique.

His will is very strong.

Yayoi is my best friend.

Kaizen is my best friend.

His last words were, 'It's okay to go.'

The grey nightjar is a bird that is active at night and, as its name suggests, it sings at night.

According to legends in Tohoku and Kanto, it is said that once you enter the 'mayoi-ya' (bewildering house), you can never get out.

That hooligan was making a fuss in the park.
