A Common Mistake in Japanese: ki o tsukete
Have you heard this Japanese expression before? When learning a foreign language, translations can sometimes skip some nuances. We found out that one of the common mistakes made in Japanese is related to the usage of the expression “ki o tsukete”.
The literal meaning is ‘be careful’ but you can also understand the phrase as a broad ‘(please) take care’. This nuance can be confusing and would explain why some foreigners use “ki o tsukete” when leaving someone’s home believing they are being polite but they are actually making a mistake.
The expression is commonly said to someone leaving on a trip and conveys the idea that one is praying for the safe trip of another.
Obviously, only the person staying sees off someone will say ki wo tsukete.
A: Please be careful during your business trip.
When they leave school after class, the teachers say to their pupils 気をつけてお帰り. You can translate the phrase as “make sure you get home safely”.
In formal Japanese, the expression’s structure is slightly longer:
A: Well, I must be going.
B: Please be careful on your way back.
A: Thank you very much.
The casual form is easier to remember:
A: Since it is late, please be careful.
B: Yeah, well, see you tomorrow
Originally, the set 気をつけるmeans “to be careful” in a possible harmful situation: crossing a street, making a fire, cutting some food… For example, mothers say “ki o tsukete ne” to their children when they are using scissors. Or, when one is walking on a steep mountain path, someone might say “you could slip easily, ki o tsukete ne”.
