My grandmother is being seen by a specialist in geriatrics.

He suffered for a long time due to tabes dorsalis.

He is a hard-working laborer.

He was moved by the sight of the waterfall.

I can hear the sound of the waterfall, and it calms my mind.

Ryo is good at calculating angles.

Rou is my son.

He worked hard all day long.

In the old days, people did a big cleaning in the twelfth month of the lunar calendar to welcome the New Year.

There are many crayfish in my pond.
