Miyamoto Kogyosho

What Miyamoto Kogyosho does

Miyamoto Kogyosho Co., Ltd. (株式会社宮本工業所) is a privately held Japanese specialty manufacturer founded in 1927, headquartered in Toyama City with a manufacturing facility in Kurobe City and an R&D base known as MiBOX. The company operates two business lines: industrial furnaces and cremation furnaces. The industrial furnace business designs and builds custom thermal equipment for aluminum processing (building materials and automotive die-casting), steel, copper, and various heat treatment applications, anchored by proprietary technologies including DMF (Dip Mold Furnace), IMF (Isuzu-Miyamoto Furnace jointly developed with Isuzu Motors and Gokoh Sangyo, achieving approximately 50% energy reduction versus conventional centralized melting), Eco-SMS, and Smart Furnace. The cremation furnace business supplies municipal crematoriums and private memorial parks with furnaces plus preventive maintenance, remote maintenance, and operation support services, and has begun international expansion with deliveries to Vietnam and dedicated websites for Vietnam and South Korea markets.

The company generates revenue through one-time equipment sales and project-based contracts — design, construction, installation — supplemented by professional services including technical consultation, after-sales support, and training. Pricing is quote-based and not publicly disclosed, consistent with custom capital equipment sales to enterprise and government buyers via a direct sales motion. Recent strategic activity includes a hydrogen cremation furnace demonstration project with Aichi Prefecture under the Ministry of the Environment, an SDB (SMART DESIGN BUILD) deployable disaster-response cremation building, the METI Manufacturing Industries Bureau Director-General Award for the IMF technology, construction of a new ZEB Ready-certified headquarters scheduled for October 2027, and expansion into Vietnam and South Korea via dedicated localized websites. The company also operates a related brand, GORIN (株式会社五輪工業), for cremation services support.
