Marusho Koi Farm is owned by Abe Toshio. It isn’t a typical set up fro a koi breeder, in fact he actually operates it from an old converted barn that was used for making saki, rather than a fish house. They produce hi quality Goshiki, Ginrin Goshiki, Kohaku, Tancho Kohaku, Sanke, Showa and Matsuwabake.
Marushu is also part of NND (Nishikigoi Niigata Direct Ltd), which is a collaboration of 3 breeders. Marushu, Kobayashi and Oomo have joined forces, sharing koi houses, mud ponds and equipment for better efficiency.
