This style of tea cup is referred to as dragon or moriage ware. Moriage originated in Japan in the 19th century but is still made today. The decoration can be created separately then attached and painted after it has been fired. The alternate process, one requiring more time, is to pipe on to the piece in layers, until the desired dimension and design is achieved then fire. Either way, the newer pieces have less slipwork and detail. Unfortunately some of the authentic vintage pieces were never marked. The cup shown here is from the 1930's.
