IZUMO JAKUZAN AKA WAKAYAMA WARE 出雲若山
Reference works of the time Morse and Brinkley conflict. Morse used Wakayama and Brinkley used Jyakuzan. Morse published his work in 1880, while Brinkley published in 1901. This is how I surmised that the change must have occurred around the late 19th or early 20th century.
