Iwatani sells gas and the equipment that goes with it — LPG, LNG, and industrial gases — to homes, businesses, and factories, mostly in Japan.
Iwatani is a Japanese gas company. If you live in Japan, there's a decent chance the propane that heats your water or cooks your dinner arrived through Iwatani's pipes and trucks. The company sells liquefied petroleum gas (LPG) to households and businesses, supplies liquefied natural gas (LNG) and industrial gases like oxygen and nitrogen to factories, and runs a chain of gas stations. It also sells the machinery and materials that go with all of this — tanks, burners, equipment — so it earns money both from the gas itself and from the hardware around it.
The LPG business is the heart of the company. Japan imports almost all of its fuel, and LPG is especially useful in places where piped city gas doesn't reach — rural towns, small restaurants, older buildings. Iwatani runs a large import and delivery network for it, so it acts as a middleman between global energy markets and millions of small customers. That gives it steady, recurring revenue, but it also means its profits rise and fall with fuel prices and the weather. The industrial gases side is the steadier, more technical business: selling hydrogen, oxygen, and specialty gases to chipmakers, steel mills, and food companies, often on long contracts. The interesting part is hydrogen. Iwatani has been pushing hard into hydrogen as a clean fuel — building hydrogen filling stations for fuel-cell cars and trucks, and supplying hydrogen for factories and power generation. It's a bet that Japan's push toward cleaner energy will create a big market, and Iwatani wants to own the infrastructure before rivals do. That's expensive and the payoff isn't guaranteed, but it lines up with the company's long history: it started out over a century ago selling gas for lamps and hasn't stopped looking for the next fuel.
Iwatani is also a familiar name in Japanese homes for a surprising reason: it sells portable gas canisters for tabletop cooking stoves, the kind you see at hot-pot restaurants and Japanese barbecues. Those little cans are a tiny product with a huge reach, and they've made the brand a household word. The company is listed in Tokyo and pays a dividend, using its cash to keep expanding the hydrogen bet and its gas network. The risk is straightforward: energy is a price-taking business, and a big chunk of Iwatani's profit depends on fuel prices it doesn't control.
