TOYOSHIMA, Aimei (ed.). — 瓦斯の実用［Practical Uses of Gas］（Gas no Jitsuyō）／瓦斯工業紀念號. Tokyo: 瓦斯の世界社 (Gas World Company), early Shōwa period (ca. 1920s–30s). 22 × 15 cm. Original Japanese stab-bound wrappers, sewn with cord ties. Ca. 150 pp., including extensive advertising section. Rare illustrated survey and promotional compendium of the Japanese gas industry, issued as a commemorative number. Opens with a historical preface attributing the invention of coal gas to William Murdoch and tracing the early development of the British gas industry, followed by a detailed biographical account of the editor, documenting his career across Tokyo Gas and regional enterprises and his founding of the trade journal Gas World. The main body presents a wide-ranging treatment of gas technology and its applications in modern Japan, including production, distribution, and domestic and industrial uses. Richly illustrated with photographic plates of installations and personnel, technical diagrams, and a substantial advertising section featuring gas appliances (heaters, bath systems, refrigeration units), promoting efficiency, cleanliness, and modern urban living. Occasional color plates further underscore its hybrid character as technical manual, trade catalogue, and instrument of industrial advocacy. Very good condition. InvHo6
