Core offering

Nitto Funka Kogyo mines, manufactures, processes, and sells calcium carbonate and natural zeolite products from its own limestone and zeolite deposits across Japan. The product portfolio spans industrial fillers (plastics, PVC, rubber, paints, coatings), food-grade calcium carbonate (MAMACALSO with HALAL and KOSHER certifications), agricultural soil amendments, animal feed additives, water purification media, radiation decontamination materials, and polyolefin masterbatch, supplied directly to industrial customers via regional sales offices and overseas branches.

Product overview

Nitto Funka Kogyo K.K. is a Japanese manufacturer specializing in calcium carbonate (CaCO3) and natural zeolite products. The company operates a multi-product portfolio consisting of two core product lines: calcium carbonate products and natural zeolite products. The calcium carbonate line includes food additive products (MAMACALSO series with HALAL and KOSHER certifications), industrial products (NITOREX, NCC, S-LITE/NEW LITE, TSS series for plastics, rubber, and coatings), masterbatch (CALPET series for polyolefins), decorative materials (CALWALL series), agricultural products (HODO/APPLON for soil improvement), animal feed additives (NIKAL, MINECAL), and industrial minerals (KANSUI/KANSUISEKI for construction and agriculture). The natural zeolite line includes water purification products (ZO series), general-purpose zeolite (NITTO ZEOLITE), thermally-treated products (ZO MG), soil improvement products (KEIZEON, HI-ZEON), compound granular soil amendments (HODO SUN series), mixed feed products (MINE ZEON), industrial zeolite (SP series), and decontamination materials (KIBOU, HIKARI, MIZUHO). The products are manufactured across five factories (Tojo, Shimotaki, Fukushima, Adachi, Iizaka, Shiroishi, Suzuka) in Japan and extracted from company-owned mines.
