This Oribe style sake cup has a picture in flat and relief Maki-e design on the vermilion lacquer ground, using sprinkled metallic powders. The picture shows “Suda ferry” which was a ferryboat crossing the Sumida river from Hashiba to Terashima in Edo. This route was also called "Umewaka ferry" or "Masaki ferry". It also depicts Masaki Inari Myo-jin shrine on the left, Suda-zutsumi dike on the right and Mt. Tsukuba visible in the distance.
There is an inscription "Sumida river/ Shozan with kao (stylized signature)/ Yoshikuni" inside the bottom stand.
This sake cup seems to be from the set of the famous landscape series.
It might be a gift from a superior.
