🎓 Explanation
To express age in Japanese, we use the counter 〜歳 (sai). Note that 20 years old is a special case called hatachi.
To count people, we use the counter 〜人 (nin). However, one person (hitori) and two people (futari) are irregular.
For four people, we say yonin (not shinin).
Nansai desu ka?
= 'How old are you?'
Kazoku wa yonin desu.
= 'There are four people in my family.'
