A term used to describe a later addition to a painting, i.e., a painting that was not originally there, but was added later. For example, painted ash ceramics of the Han dynasty in China with badly peeled off colors were painted over, or overglaze painting was added to the margins of old painted ceramics. It is not possible to add underglaze painting to ceramics with underglaze painting, such as underglaze blue and underglaze red, but it is easy to add overglaze painting to such ceramics, so this type of overglaze painting is common. There are two types of kosozuke with afterglaze painting in the style of ten-aka-e or iroe shozui-style: those made immediately after their arrival in Japan, i.e., during the Edo period, and those made in the modern period. Either way, they are still a kind of forgery.
