It's a cross between Nijiseiki' X 'Doetsu'. In 1948 Kikuchi stated that the 'Doitsu' cultivar originated from the 'Kanagawa' Prefecture (government district) of Japan, it was also stated that 'the Kawasaki City area' was the part of 'Kanagawa' that the 'Doitsu' chance seedling originated, but no date was given for it's discovery, yet Dr. Minoru Kajiura 'the director of the Horticultural Research Station' in Hiratsuka, Kanagawa, Japan stated that 'Doitsu' originated from the 'Niigata Prefecture' of Japan. So chances are that 'Kanagawa' was not the first place to have 'Doitsu'.
Originally cultured in the Kanto region sometime following the Meiji Restoration.
