My nephew is very smart.

He was carrying a box for books on his back, like an ancient scholar.

This forest is densely packed with plants like Yayoi.

I intend to do this job later in life.

We celebrated his promotion.

I started to feel old age.

He did his best to pursue and attack the enemy.

In the Yayoi season, vegetation grows thickly.

He is a child of older parents, and because his parents are elderly, he himself felt the responsibility of adulthood from an early age.

This room has a strange smell, doesn't it?
