The mystery of backwards numbers on on the outside of cooking pots

I’m sorry I can’t post an images here as the community doesn’t allow it. So I will do my best to describe, tonight I was in a restaurant in Tokyo and I came across a stainless steel cooking pot that had measurements stamped on the outside reversed? For example, the number 3 was written backwards. Why? What is the reason for this? Apart from a stamping mistake.
