I have a pitcher that I inherited that is the same shape/style as yours. Over the years I have seen it called a 1) pitcher, 2) milk pitcher, 3) water pitcher a 4) lemonade pitcher and a 5) cider pitcher!
However, yours n mine do not have an "ice lip" on the pouring spout to keep the ice from pouring out (this was a newer innovation on this style for lemonade pitchers).
Bottom line, it was a very popular style pitcher! If you search "Nippon cider pitcher" you will find many, many in the same pitcher style.
Wish i could see your makers' mark better. The most common that you see these days is the "China O-H Nippon".
