IWATANI CORPORATION
What does Iwatani do?
Iwatani sells energy and gas. It pipes and delivers LPG and sells cassette-gas stoves and canisters to homes and small businesses, and it supplies oxygen, nitrogen, argon, helium and hydrogen to factories, hospitals and electronics makers. Customers pay through gas volumes, equipment sales and long-term supply contracts.
Two things make it unusual. It is the only company in Japan that produces, ships and dispenses liquid hydrogen end to end, and it is the country's largest helium importer. It also runs a materials arm that trades rare earths, mineral sands and titanium.
The business runs in three segments — Integrated Energy (LPG, cassette gas, city gas, hydrogen retail), Industrial Gases & Machinery (air-separation gases, helium, hydrogen), and Materials (rare earths, PET resin, stainless, electronic materials). FY03/26 revenue was ¥908.5bn, up 2.9% YoY, split roughly 41% / 32% / 24% across the three.
The stock trades near ¥1,995, about 10x earnings, 1.05x book, on a 2.4% yield, for a widely-held ¥459bn company that has raised its dividend for years. But OP fell 17% YoY in FY03/26 as helium prices and LPG import costs squeezed the base, and reported net income was flattered by a one-off gain on selling the old Tokyo head office.
So the question is whether the cash-generative gas base can fund the hydrogen and critical-minerals build without letting returns drift.
What has driven the stock over the past two years?
Policy, commodities, and thin-margin operations all moved the shares.
01 · THE TRADING-HOUSE RE-RATING Through 2024 the shares rode the wave that lifted Japan's trading houses, helped by Berkshire's stakes and by hopes for hydrogen. Iwatani also built a stake of about 21% in Cosmo Energy Holdings, an oil refiner, which the market read as an ambitious energy bet. The stock climbed toward its 24-month high.
02 · PEAK ¥2,445 The shares topped out in mid-2024, just before a four-for-one stock split took effect on October 1, 2024. From there, cooling enthusiasm for the trading-house trade and a softer earnings outlook started to pull the price back.
03 · THE APRIL-2025 CRASH In early April 2025 global markets sold off hard on new US tariffs. Iwatani, exposed to trade and industrial demand, fell with them to a trough of ¥1,148 on April 7, roughly half its 2024 peak. Nothing company-specific broke; the fall was macro.
04 · WHERE IT STANDS NOW From that low the shares have recovered about 74% to ¥1,994.5, helped by the hydrogen and critical-minerals story and a broad market rebound. The stock is still about 18% below its 2024 peak, so the round trip is not complete.
What investors disagree about
Core earnings, hydrogen investment, and critical minerals drive the debate.
OP fell 17% YoY to ¥38.3bn, but net income rose 18% YoY to ¥47.7bn. The gap came from a gain on selling the former Tokyo head office and from equity earnings on the ~21% Cosmo Energy stake — items that sit below OP.
- Helium and LPG cut FY03/26 OP by ¥11.7bn, but both effects can reverse. Management now guides a rebound to ¥48.8bn. That recovery, plus recurring Cosmo earnings, would show the core reached a cyclical trough.
- Without the head-office gain, FY03/26 was weaker than net income suggests. OP has missed the PLAN27 path for two years and remains far below the ¥65bn target, so the operating result matters more than another one-off gain.
Iwatani is the only company in Japan that makes, ships and dispenses liquid hydrogen, and it runs the country's largest network of hydrogen stations. The business is small and loss-making today, funded by the cash it earns from LPG and industrial gases.
- This is infrastructure no rival can quickly copy, and Japanese policy is pushing hydrogen hard.
- If a hydrogen economy scales for trucks, ships and industry, Iwatani already owns the production, the tankers and the stations — the toll road.
- The build also deepens the same cryogenic skills behind its helium and industrial-gas business.
- Hydrogen keeps losing the mobility race to batteries, and the build stays dependent on government money with no breakeven date disclosed.
- Every year of capital that goes into stations and liquefaction is capital not returned to shareholders, invested against an unproven market.
Iwatani's Materials arm trades rare earths, mineral sands from Australia and titanium from Norway. In March 2025 it joined France's Caremag heavy-rare-earth project alongside JOGMEC, the Japanese state resource agency, with a long-term contract for the metals used in EV and defense magnets.
- This is a policy-backed role, not a normal trade. METI is putting about €100m into Caremag through JOGMEC, and the contract targets around 20% of Japan's future demand for dysprosium and terbium — the heavy rare earths that keep magnets working at high temperature.
- It is still a small slice of a low-margin Materials segment, and Iwatani's own mining profitability fell in FY03/26.
- The Caremag plant is years from full output, resource prices are cyclical, and rare-earth supply is exposed to Chinese policy.
- The upside is real but slow, and it will not move group earnings for a while.
What is changing in who owns it, who buys from it, and the edge?
- Foreign holders reached about 20% of the register by March 2026, up from roughly 11% in 2019; Norway's sovereign fund trimmed out of the top ten and State Street entered.
- Index flows and the trading-house re-rating drew the global money in.
- MUFG, Resona and Nippon Life still hold about 6% between them as static policy stakes, a legacy of old lending relationships.
- It is a block that could be sold down, which would free cash and widen the float.
- Industrial Gases & Machinery revenue rose 6.4% YoY, led by air-separation gas to electronics and optical-fiber makers investing in capacity.
- That is the highest-quality, contract-based demand holding up while energy wobbles.
- The Caremag rare-earth contract pairs Iwatani with JOGMEC under a Japan-France critical-minerals accord, because Japan wants magnet metals sourced outside China.
- The buyer of last resort is becoming the Japanese state, which is unusually durable demand.
- Specialty-gas OP fell about ¥5.75bn on a weak helium market.
- Helium is scarce, but its price is cyclical, so even a scarce-input edge does not shield margin from the commodity cycle.
- The liquid-hydrogen network is the deepest edge and the least profitable, because the hydrogen market is still forming.
- Iwatani is paying now for an option that may pay later.
Disclosure & Capital Levers
Three actions could lift returns and make PLAN27 easier to judge.
- Iwatani holds ¥237.6bn of investment securities while the operating business earns roughly 5.7% ROIC. A cross-holding sale or buyback at the FY03/27 results would begin moving that capital toward a higher return.
- PLAN27 commits ¥470bn over five years, most of it into hydrogen, industrial-gas capacity and resources.
- The Caremag rare-earth deal, green-LPG work and the hydrogen supply chain are the growth options that spend is meant to buy.
- The risk is that it deploys without converting: operating ROIC is about 5.7% against the 6% ROIC target.
- Management guides OP up 27% YoY to ¥48.8bn for FY03/27, on helium and LPG prices normalizing and on price increases in industrial gases.
- Because much of the swing is external prices rather than self-help, the recovery is only partly in management's hands.
Scenario Pathways
The cases start from ¥1,994.5 and FY03/27 OP guidance.
