Maruwi Propane: LP gas for the household (1953)

The prototype of a philosophy that controls the downstream

What the Maruwi Propane decision demonstrates is a nose for markets that lie outside the existing flow of trade rather than along the extension of the existing business. Moving from wholesaling industrial cylinders to factories and shops into a consumer business that reaches the household kitchen changed not only the goods handled but the very point of contact with the customer — it was a bet on remaking that contact. Aiming at the territory city-gas infrastructure did not reach was a choice that turned the weakness of arriving late into an advantage.

What makes the shift interesting is that it was not left as a one-off product launch: over fifteen years the company built the skeleton of a distribution system — dealers, filling depots, affiliated sales companies. The integrated supply chain from upstream to downstream, symbolised by the Sakai LPG import terminal of 1980, was an investment that only had meaning because of the consumer distribution network established in 1953. The habit of thinking in terms of how to make a product that arrives in the hands of ordinary people reappears repeatedly as the basic form of Iwatani’s later expansion, hydrogen included.
