This is a vintage 20th century, 1985 bone china set by Kochi Nortiake in pattern 9916 that is named Genroku. This Memphis School style design was produced only in 1985 and it was made for the Japanese market only, meaning this pattern was not exported. In the 'big picture' so to speak, this is a fairly rare pattern for late 20th century Noritake wares, however the fine china for dining market is currently slumped. Sets do not sell for what they used to sell for a few decades ago and the market was further impacted by the Recession. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
