Edo Period Arita Akae Imari Japanese Porcelain Jar / 有田焼赤絵伊万里焼

This is one of the pieces from yesterday's treasure hunt I wrote about in my last post, purchased from an antiques dealer in Salem, Massachusetts, who had absolutely no idea whatsoever what it is, which was fortunate for me since I picked it up at an exceptionally low price.   Unfortunately it is missing the lid, but that's fine with me.    I really love this piece.

  It is a Japanese Arita Akae Imari porcelain ginger jar measuring approximately 6 1/2" tall and 3 1/2" dia. base, & 3" mouth.  Arita being where it was made, Akae is the name for the style, and Imari being the port of export.

The only marking is a small "Ri" リ on the mouth of the jar.  As of this posting, I have no idea what it represents.   Unfortunately I'm unable to narrow its age down to a specific date range at this time although I estimate it to be in the range of late Edo period 1850s to early-mid Meiji period 1880s.
