Today’s business Japanese is “Ma-kka”.
What does it mean?
It literally means “Very Red”. Very red?
It is used in accounting field.
This means “Big loss”.
“Aka” is “Red”, meaning unprofitable. Therefore, “Ma-kka”means “The loss is big”.
For example, we say, “Kyonen wa ma-kka datta.”, meaning “The loss was big last year.”
On the contrary, “Kuro (Black)” means profitable.
I hope everyone goes in black in 2022!
