Chugokukogyo Co., Ltd. (中国工業株式会社) is a Japanese industrial manufacturer founded in 1950 and headquartered in Kure, Hiroshima Prefecture. The company specializes in high-pressure gas containers and storage/distribution systems, with its core business being LP gas containers ranging from 2kg household units to 500kg industrial containers and bulk storage tanks up to 2.9 tons. Chugokukogyo operates three product divisions: High-Pressure Equipment (LP gas containers, supply plants, bulk storage tanks, specialty gas containers), Steel Structure Equipment (annealing furnace inner covers for steel manufacturers), and Facility Equipment (FRP products including feed tanks, chemical tanks, deodorizing devices, aquaculture tanks, and livestock equipment). The company pioneered Japan's first LP gas composite container under the Placompo brand, featuring lightweight, explosion-resistant all-plastic construction.

The company operates purely on a direct B2B sales model through a nationwide regional sales network spanning Hokkaido to Okinawa, with branches in Tokyo, Sendai, Osaka, Hiroshima, Fukuoka, and Nagoya. Revenue is generated through one-time product sales and plant engineering/construction services. The company holds ISO 9001 and ISO 14001 certifications and operates under High Pressure Gas Safety Act registration. Leveraging over 60 years of manufacturing experience and 60+ million cumulative units produced, Chugokukogyo is positioned as Japan's top manufacturer of LP gas containers. Its customer base spans household LP gas users (SMB), industrial LP gas users (enterprise boilers, manufacturing), specialty gas users (semiconductor, fluorocarbon), agricultural operations, and steel manufacturers. Revenue for FY ending March 2026 was 115 billion yen (approximately $760M USD). The company is publicly listed on the Tokyo Stock Exchange Standard Market (ticker: 5974) with 259 employees and no disclosed subsidiaries or parent company.

Core offering

Chugokukogyo manufactures and sells high-pressure gas containers, with a focus on LP gas containers ranging from 2kg household units to 500kg industrial units and bulk-type storage vessels (up to 2.9 tons). The company operates three divisions: High-Pressure Equipment (LP gas containers, LP gas plant equipment, bulk storage tanks, special gas containers), Iron Construction Equipment (annealing furnace inner covers), and Facility Equipment (FRP feed tanks, chemical tanks, deodorizing devices, aquaculture tanks). The proprietary Placompo line is Japan's first composite LP gas container combining a plastic liner with an outer composite casing.

Product overview

中国工業株式会社 is a leading Japanese manufacturer of LP gas containers with over 60 years of experience and 60 million+ units produced. The company operates three main product divisions: (1) High-Pressure Equipment Division offering LP gas containers in steel and aluminum (2kg-500kg), LP gas supply plants, bulk storage tanks, and special high-pressure gas containers; (2) Steel Structure Equipment Division producing annealing furnace inner covers and custom steel products; (3) Facility Equipment Division manufacturing FRP products including feed tanks, chemical tanks, deodorizing devices, aquaculture tanks, and livestock equipment. The company is notably recognized for developing Japan's first LP gas composite container brand 'Placompo' (プラコンポ), available in 8kg, 17kg, and 20kg sizes. The product portfolio is organized around storage and distribution total systems for LP gas and industrial applications.
