Fukagawa is the family name of the founder and owner of the Koransha company. The combination of the orchid mark of Koransha and signature Fukagawa sei/zo appears to have been used (as in this vase) until the company was split in 1889, after which the orchid mark started to appear alone in wares of the Koransha company.
