Marubeni and Itochu spring from one root: the peddling of Omi hemp cloth that the first Ito Chubei began from Osaka in 1858. In 1872 he opened Benichu, a draper’s shop in Osaka’s Honmachi, and the family trade grew into a bridge that carried Omi-merchant commerce into modern trade. In 1918, under the second Ito Chubei, Itochu Corporation and Marubeni Shoten were split apart — the same lineage divided into two houses, not out of rivalry but as a way of carrying the family trade onto the joint-stock form. Marubeni set out from there as a trading house built around textile wholesaling.
Incorporated in 1921, Marubeni Shoten added yarn and cloth to sundries, metals, chemicals and foodstuffs, opened branches across Korea, Manchuria and China, and grew large enough to run its own factories. Then wartime control erased its autonomy: in 1941 it merged with Kishimoto Shoten and Itochu into Sanko K.K., and in 1944 was reorganized into Daiken Sangyo, a combine of some forty-five subsidiaries. Corporate continuity was severed from the continuity of the trade name — and the outline of that wartime giant became the very frame that postwar antitrust would break apart.
In 1949 the law against excessive concentration of economic power split Daiken Sangyo into four — Marubeni, Itochu, Kureha Boseki and the Amagasaki Nail Works — and Marubeni was re-founded that December. The terms of the split shaped everything after it. In the negotiations led by Ichikawa Shinobu, the trading goodwill was divided so that cotton went to Itochu and silk, wool, hemp and synthetics to Marubeni. In an age when cotton was the single most profitable fibre, Marubeni set out stripped of exactly that — a handicap it would spend the next decade filling.
1979Late to oil — crude volume a third of Mitsubishi’s
Marubeni listed on the Tokyo Stock Exchange in 1950 and at once ran into a post-Korean-War collapse in cotton prices — from which, having been handed everything but cotton in the split, it was ironically half-spared. It moved to fill the missing cotton by merger. In 1955 it absorbed Takashimaya Iida, taking on its machinery, metals and wool trading rights and renaming itself Marubeni-Iida — the first postwar textile trader to lay the foundations of a general trading house.
The absorption soon surfaced as a lead. By 1961 Marubeni had opened a half-year gap of $111.1M (¥40bn) over Itochu in non-textile sales — the machinery-and-metals rights won from Takashimaya Iida turning into the very source of the difference that pulled it clear of a pack of look-alike textile wholesalers. A 1966 merger with Totsu strengthened steel, and in 1972 the company took the name Marubeni Corporation. Ichikawa Shinobu, its postwar builder, batted away the era’s talk of a “distribution revolution” that would make trading houses obsolete, casting the language skills and global networks of a sogo shosha as a resource only it could deploy worldwide.
But scale brought its own exposure. As Marubeni broadened from textiles into machinery, metals and timber, public opinion turned on the trading houses’ “speculative trading” in the early 1970s; then, in 1976, the Lockheed bribery scandal placed Marubeni at the centre of a political affair and cost it management, credit and standing at a stroke. Compounding the damage, it had come late to oil — its crude volume a third of Mitsubishi’s and half of Itochu’s — a gap in the next earnings pillar that all its absorption-built breadth in non-textiles could not close.

2001Steel folded into Itochu-Marubeni Steel
2002Root-and-branch bad-asset cleanup; the turnaround
2003Head office moves to Tokyo
In 1987 president Haruna Kazuo named, in plain words, the distortions that the rapid rise had baked into Marubeni’s earnings: a race to be number one in sales rather than in profit, a weakness in domestic business, and vertical silos that walled off one division from the next — the inner costs of climbing from textile trader to general trading house. But naming a disease is not the same as curing it.
The unrealized losses of the bubble were cleared not at once but in small doses. From Toriumi Iwao’s early restructuring in 1992, through 1998 — when the delay surfaced as a widening gap with an Itochu that had booked its special losses sooner — to the root-and-branch cleanup of 2002, Marubeni spent a decade on the same problem, its slow recognition of bad assets making it, in the phrase of the day, an epitome of the “lost decade.” The rival that had taken the profitable cotton goodwill back in 1949 again moved first, and Marubeni carried the delay as numbers.
The turnaround came by shoring up the defence first. To escape a share price in the ¥100s and a heavy debt load, Marubeni narrowed its group, merged its steel arm with Itochu’s into Itochu-Marubeni Steel in 2001, and held its credit lines in place — measures not to grow profit but to keep a break in cash flow from turning credit anxiety into collapse. Only once that body was ready could it catch the resource-price tailwind that followed.

Marubeni had long consolidated under US accounting standards, and in the resources boom of the late 2000s it reached record sales while holding a net profit even through the 2009 Lehman shock — the accumulated breadth of its trading volume partly absorbing the swings of resource markets. From fiscal 2012 it moved to IFRS and climbed from the middle of the pack toward the top, even as a resource-dependent earnings structure hardened: one that now takes every market downturn straight onto consolidated profit.
The same appetite for scale that had built Marubeni by absorption now met its limit in a single acquisition. In 2013 it completed the roughly $2.7 billion buyout of the US grain major Gavilon, reaching top-tier grain-handling volume; grain prices fell right afterward, and profit slid sharply — the difficulty of the scale-chasing trading-house acquisition laid bare in numbers. When Kakinoki Masumi took the presidency in 2019, a blanket impairment on Chile copper and other interests pushed Marubeni to a net loss of $1.8B (¥197bn) in the year to March 2020, its first in eighteen years.
The rebuild ran through the same tenure. Kakinoki tightened investment discipline, shifted the power business from asset-heavy generation toward operation and services, and lifted the non-resource share of earnings; profit V-shaped back and, as resource prices rose, Marubeni renewed record highs — a net profit of $3.9B (¥543bn) in the year to March 2023. In 2022 it sold the Gavilon grain business and put the recovered cash toward paying down debt. In 2025 it topped a new medium-term plan, “GC2027,” with a market capitalization above $66.8B (¥10tn) by the year to March 2031 and a large three-year growth-investment programme — and, passing over fourteen more-senior candidates, installed Omoto Masayuki as president. The company that had grown by absorption had rewritten its sequence: sell and return capital to sharpen efficiency first, then push large investment.
The cost of a business propped up by political ties
At the heart of this affair is the moment when a trading house’s business model — one that tries to secure the rights to big-ticket goods through closeness to politics — crossed the line of the law and shook the company itself. For goods such as aircraft, which are costly and whose selection is entangled with politics, the distance between an agent’s trading rights and political maneuvering narrows easily. Marubeni stepped over that line, was placed at the centre of a bribery scandal, and lost management, credit and industry standing — tangible and intangible assets alike — all at once. It was at once the crime of individuals and an organizational problem: the trading customs that pushed them into it.
What the affair left behind was not only a monetary loss. Stripped of the capacity to sail by setting mid- and long-term hypotheses, Marubeni was left chasing immediate crises in a “voyage without a chart,” and that prolonged its stagnation. A failure of governance does not end with the one-off price of fines or damages; it erodes the very power of a company to conceive its future. Where to draw the line between winning trading rights and the bounds of law and ethics — the Lockheed scandal is an instructive case that long displayed, in Marubeni’s stagnation, the size of the price of crossing it.
The heart of this decision was not that Marubeni carried out some sweeping reorganization, but that its incoming president named his own company’s weaknesses in his own words. The race to be number one in sales, the weakness in domestic trade, the vertical silos that walled off the divisions — each was the underside of the success that had carried Marubeni from a textile trader to a general trading house, an inner weakness hard to see from outside. Haruna named them one by one in plain, unadorned language. To frame the aim as a “rebuilding into a strong trading house” was itself a declaration that it all began with admitting where the company actually stood.
Yet naming a disease and curing it are two different things. The weaknesses Haruna listed were not resolved during his tenure; only after more than a decade — the cleanup of financial engineering, the pruning of subsidiaries, the disposal of bad assets — did they finally connect to the rebuilding of the 2000s. An accurate diagnosis promises no early cure. “Rebuilding into a strong trading house” can be read as a prelude that shows how long that distance was. Looking at today’s Marubeni, which has renewed record profits on high resource prices, how far did this 1987 self-diagnosis of its earnings constitution bear fruit, and what did it carry over? It leaves a question worth re-asking at every turning point.
The heart of this judgment lies in Toriumi correctly naming Marubeni’s weakness. His diagnosis — that the company must stop dressing up bad results by pushing them into the future, and should instead bring its unrealized losses into the open and share a sense of crisis — hit the mark. But what he could actually cut into stayed within easy reach: liquidating low-efficiency subsidiaries and merging loss-making units with profitable ones. Inferior to its higher-ranked rivals in both financial strength and earning power, Marubeni could not bring itself to the bold step of taking its unrealized losses as losses all at once, and it left the painful core for later. However sharp the diagnosis, without the stamina to withstand it the treatment cannot keep pace.
Deferring the unrealized losses the bubble had produced in small doses, rather than settling them in one stroke, was not Marubeni’s story alone but the shared shape of the Japanese firms of the “lost decade” that put off fixing their losses. From the early restructuring Toriumi began in 1992, through 1998 when the delay surfaced as a gap with rivals, to 2002 when it dealt with its bad assets in earnest, Marubeni spent ten years on the same problem. Can a company summon the resolve to book the losses and the stamina to withstand them at the same time? Lacking either of the two demanded at the entrance to a crisis, even a sharp diagnosis ends as an empty promise. The 1992 cleanup quietly shows the weight of that sequence.
Shore up the defence first, then ride the market’s wave
The core of this decision was that, in place of a flashy growth plan, it concentrated first on building a body that would not collapse. Having fallen behind in disposing of bad assets, Marubeni — to escape an “epitome of the lost decade” of a share price in the ¥100s and heavy interest-bearing debt — narrowed its group companies, merged its steel business with a rival’s, and kept its credit lines from being cut. These were not measures to raise profit but defensive treatments to stop a break in cash flow from turning credit anxiety into an actual collapse.
That the Marubeni which had shored up its defence could then turn to record profits owed something, too, to the tailwind of rising resource prices that blew afterward. Separating skill from luck is hard; but at the least, unless you first ready a body that can catch the wave when it comes, a tailwind cannot be used. For a general trading house that entrusts its earnings to the uncontrollable waves of the resource markets, the very management of sequence — shoring up the defence on the way down, going on the offensive on the way up — is the crux of the business. Rebuilding from the “losers’ camp” is a suggestive case of a company learning that sequence in the body.
What a scale-chasing trading-house M&A left behind
Gavilon’s acquisition and later divestiture threw into relief, within Marubeni’s own history, the difficulty of the scale-chasing trading-house M&A. This was a company that had widened the breadth of its business after the war by piling up absorptions, and it had long held the success memory of taking scale through large acquisitions. But the goal of standing among the world’s top handlers of grain volume was the flip side of taking market risk onto its own books. Bought at the top, prices fell right afterward, and as trade friction ate at the value of its collection network, the company was confronted with the reality that expanding scale does not translate directly into profit.
That said, in the way it fashioned an exit over ten years, one can also read this company’s own learning. Marubeni did not dump Gavilon in a fire sale; it waited for the opening of high grain prices and sorted out only the assets that promised returns — fertilizer, export terminals and the like — to keep. It was a judgment that converted the failure of the acquisition into recovery through the picking and discarding of assets. From the scale metric of handling volume to the question of whether a margin worth the investment can be earned — how far the Gavilon experience shaped the investment discipline that later Marubeni espouses is a question its subsequent capital allocation between resources and non-resources continues to ask.
The trading house that bets on resources, and its control
What this decision reflects is the constitution of a general trading house whose consolidated profit and loss directly absorbs the resource markets. Interests acquired at high valuations in a boom rebound as impairments once the market turns. The Kakinoki regime’s blanket impairment can be read as a judgment tilted more to defence than to offence: at the milestone of taking office, it cleared in a single batch the latent losses carried over from the previous tenures. The lightness of having set the baggage of the past down — even at the cost of a large loss — became the ground for the subsequent V-shaped recovery and for the rebuilding of investment discipline. That it moved to clean up pushed by a sudden market slump, rather than lancing the boil while the good times lasted, is where the character of this judgment shows.
That said, the tilt toward resources itself has not vanished. As the expansion of Centinela shows, Marubeni still bets on copper — a market commodity — while facing resources by offloading that risk onto outside capital. The investment discipline that turned the impairment into an institutional lesson also became a premise for the growth investment that the successor president, Omoto Masayuki, now espouses. Earning on resources, sinking on resources, and turning back to resources again — the question of how a trading house comes to terms with the market cycle still remains in Marubeni’s management.
Market capitalization as a yardstick, and a step toward meritocracy
The core of this decision is that it draws the counterpart a general trading house’s management faces one notch closer — from the accumulation of businesses toward the valuation of the capital market. Marubeni has, until now, spent its effort on how to dampen the swings in its earning power, through the waves of the resource markets and the wounds of impairment. Setting a figure — a $66.8B (¥10tn) market capitalization — at the summit of its medium-term strategy can be read, on that same line, as a declaration that it will squarely take on the level of value seen from the shareholder’s side as a management yardstick. Yet market capitalization is an external indicator swayed by the market and by interest rates as well, and how a management that raises it as a target reconciles it with discipline is left to the execution ahead.
The other implication lies in the changed shape of presidential selection. The personnel move — installing, over fourteen more-senior people, a figure with a boomerang career, and so breaking the trading-house pattern in which career insiders reach the summit in order of seniority — shows a will to hurry growth in the very form of the regime. That a company which has passed through the defensive period of impairment placed at the helm, at the turn toward offence, a president chosen from outside custom — whether that combination proves fortunate is, together with the fate of that target, entrusted still to what lies ahead. How much offence can be stacked on a foundation shored up by defence? As of this writing, the question remains open.
