Often Confused With
'Oikutsu desu ka' is the polite and formal way to ask someone's age. 'Nansai' is informal and should not be used with elders or in formal settings.
'Nan sai desu ka' is slightly more polite than 'nansai' but less formal than 'oikutsu desu ka'. It can be used with people of similar age or slightly younger, but 'oikutsu desu ka' is safer for elders.

How to Use It
Usage Notes
The word 'nansai' is primarily used in informal contexts when asking for the age of children or very close friends. It carries a casual tone and lacks the politeness required for addressing elders or in formal situations. When in doubt, opt for the more polite 'oikutsu desu ka'.
Common Mistakes
A common mistake is using 'nansai' when speaking to someone older or in a professional setting, which can be perceived as impolite. Another mistake is assuming it's universally acceptable for asking anyone's age, neglecting the importance of social hierarchy in Japanese.
Tips
Choosing the Right Age Question
Always consider your relationship with the person and the formality of the situation. 'Nansai' is casual, while 'oikutsu desu ka' is polite.
Avoid with Elders
Using 'nansai' with someone older than you or in a formal setting can be perceived as rude. Stick to 'oikutsu desu ka' in such cases.
Politeness Levels Matter
Japanese culture places a high value on politeness and respecting age. Using the appropriate language shows consideration for others.
Word Origin
The word 'nansai' originates from the Japanese word 'nan' (何 - what/how many) and 'sai' (歳 - years old). The kanji '歳' is often read as 'sai' when referring to age.
Cultural Context
In Japanese culture, directly asking someone's age can sometimes be considered intrusive, especially if they are older or if the relationship is not close. Using polite forms like 'oikutsu desu ka' is crucial to show respect and avoid causing discomfort.
Memory Tip
Think of 'nansai' as 'naughty' age, because you only ask naughty children their age so casually! For everyone else, use the polite 'oikutsu'.
