Fujikohki

What Fujikohki does

Fujikohki Co., Ltd. (富士工器株式会社), founded in 1947 and headquartered in Nagoya, Aichi Prefecture, is a privately held Japanese manufacturer of LP (liquefied petroleum) gas supply equipment. The company describes itself as Japan's only comprehensive manufacturer covering the full LP gas supply chain from containers to burner-inlet equipment. Its portfolio spans three categories: household LP gas equipment (containers from 2kg to 2,900kg, single-stage and automatic changeover regulators with odor-countermeasure features, gas valves, low-pressure and burner hoses, gas leak alarms); commercial and industrial LP gas equipment (manifold devices and accessories, pressure gauges, ON-OFF and fuse-box gas valves, high-pressure hoses); and bulk supply systems (bulk storage tanks from 148kg to 2,900kg plus dedicated bulk regulators). The firm also publishes a 116-page comprehensive electronic catalog and a bulk regulator periodic replacement manual for distributors.

Manufacturing is distributed across three domestic factories — Nagoya (established 1954), Yamanashi (1962) and Inazawa (1964) — plus a Sino-Japanese joint venture, Shanghai Fuji Koki Co., Ltd., established in 1997 (Japanese 60% / Chinese 40% ownership) which produces bulk storage tanks and general pressure vessels for the Chinese domestic market. A related company, Gifu Fuji Koki Co., Ltd., supplies die-cast regulator parts and gas valves. The commercial model is B2B route sales through a national network of 6 regional branches (Hokkaido, Tohoku, Kanto, Chubu, Chushikoku-Shikoku, Kyushu) and 8 sales offices, complemented by channel partnerships with major LP gas distributors (Mitsuuroko, Sanrin, Maruei Gas, Nagoya Propane, Yoshitake Sangyo) and trading companies (Yuasa Shoji, Sakae Trading, Komatsu Bussan, Chubu Corporation).

The company claims "overwhelming" domestic market share in LP gas supply equipment, with cumulative production exceeding tens of millions of containers and bulk storage tank exports surpassing 100,000 units as of October 2014. Products comply with Japan's high-pressure gas safety regulations under METI oversight and main factories carry ISO 9001 certification. Fujikohki is led by President and Representative Director Shoichiro Maeguchi (前口庄一郎), who also serves as Chairman of the Shanghai joint venture and Representative Director of Gifu Fuji Koki. The firm is a member of multiple industry bodies including the Japan LP Gas Association, Japan LP Gas Supply Equipment Industry Association, Japan LP Gas Equipment Inspection Association, and the High-Pressure Gas Safety Association.

Core offering

Fujikohki manufactures and sells LP gas supply equipment covering the entire gas delivery chain — from LP gas containers and bulk storage tanks to pressure regulators, gas valves, hoses, manifold devices, pressure gauges, and gas leak alarms. The company produces household LP gas equipment (2kg–50kg containers, single-stage regulators, automatic changeover regulators, household gas valves), commercial/industrial LP gas equipment (container valves, manifold assemblies, high-pressure hoses, pressure gauges), and bulk supply systems (148kg–2,900kg bulk storage tanks and bulk regulators). Products are sold through a nationwide B2B network to LP gas distributors and trading companies.

Product overview

Fujikohki Co., Ltd. is a comprehensive LP gas supply equipment manufacturer offering a unified portfolio of products spanning the entire gas delivery chain — from LP gas containers and bulk storage tanks to combustion inlet supply equipment. The product line is organized into three main categories: household LP gas equipment (including containers, single-stage regulators, automatic changeover regulators with odor countermeasures, various gas valves, hoses, and gas leak alarms), business/commercial LP gas equipment (including container valves, automatic changeover regulators, manifold devices, pressure gauges, and high-pressure hoses), and bulk supply systems (bulk storage tanks and bulk regulators).

Scale indicators7 records

Recent moves11 records

Expansion highlights6 records

Broad incumbents

• Rinnai Corporation: Rinnai is Japan's largest gas appliance manufacturer, producing water heaters, stoves, and related LP gas consumption equipment. Downstream customer of LP gas equipment, but adjacent enough to represent a potential vertical-integration threat or partnership opportunity for Fujikohki.
• Iwatani Corporation: Iwatani is Japan's largest LP gas distributor and a major industrial gases player with significant in-house LP gas equipment manufacturing capacity. Comparable to Fujikohki across both LP gas distribution and equipment, but at substantially larger scale and broader scope.
• Nippon Sanso Holdings: Nippon Sanso (parent of Taiyo Nippon Sanso) is a global industrial gases major with Japanese LP gas and related equipment exposure. Comparable to Fujikohki in industrial gas infrastructure but at vastly larger scale, representing both a competitor in gas-handling hardware and a potential acquirer.
• Kitz Corporation: Kitz is a leading Japanese valve and flow-control manufacturer serving oil & gas, chemical, and industrial markets. Comparable to Fujikohki as a domestic valve/hardware supplier to LP gas and broader industrial fluid systems, though Kitz is far larger and more diversified.

Direct peers

• Yano Engineering Co., Ltd. Yano Engineering is a Japanese manufacturer specializing in LP gas supply equipment, regulators, and safety devices. Closely comparable niche peer to Fujikohki with overlapping customer base among Japanese LP gas distributors.
• Yoshitake Sangyo Co., Ltd. Yoshitake Sangyo manufactures LP gas valves, regulators, and fittings for household and industrial applications in Japan. Listed as a Fujikohki channel partner but operates overlapping product lines, making it the closest direct competitor in the Japanese LP gas supply-equipment niche.
• Sankyo Seisakusho Co., Ltd. Sankyo Seisakusho manufactures LP gas pressure regulators, gas valves, and related safety equipment for Japanese households and commercial users. Highly comparable to Fujikohki's core regulator and valve business serving the same Japanese LP gas channel.
• Yutaka Manufacturing Co., Ltd. Yutaka Manufacturing produces industrial valves, regulators, and fluid control equipment for gas and chemical applications in Japan. Directly comparable to Fujikohki's regulator and valve product lines for industrial LP gas systems.
• TATSUNO Corporation: TATSUNO Corporation is a Japanese manufacturer of fuel dispensers and LP gas equipment, including tank trucks, pumps, and gas station hardware. Directly comparable to Fujikohki as a domestic specialist in LP/LNG fluid handling hardware serving Japanese energy distributors.

Emerging players

• CKD Corporation: CKD Corporation manufactures pneumatic and fluid power components, including valves and regulators used in gas and industrial automation systems. Comparable to Fujikohki in fluid power valve/regulator technology, though CKD focuses on factory automation rather than LP gas distribution.
