The Wikipedia article (which, as such, needs to be corroborated) says:

"In the 13th century, Southern Song mathematicians changed digits for 4,
5, and 9 to reduce strokes. The new horizontal forms eventually
transformed into Suzhou numerals. Japanese continued to use the
traditional forms."

So there is a distinction between the alternate forms Eduardo is
describing, and the Suzhou ("Hangzhou") numerals derived from them that
Richard cited.
