Kongō Gumi, founded in 578 in Osaka, is cited in almost all rankings as the oldest company in the world. However, this title deserves to be reexamined: the company lost its legal independence in 2006, absorbed by the Takamatsu Construction group. The question of business continuity, family transmission, and legal status redefines what it truly means to be “the oldest company in the world.”
Kongō Gumi after 2006: a continuity of activity without legal autonomy
The acquisition of Kongō Gumi by Takamatsu in 2006 ended nearly fourteen centuries of autonomous legal existence. The entity continues to operate as a subsidiary specializing in the construction and restoration of Buddhist temples, but it is no longer an independent company in the sense of Japanese commercial law.

This point is far from trivial. Business historians, notably Jeffrey Fear from Universität Basel, emphasize that the break in autonomous legal existence weakens the claim of antiquity. Other entities, such as the Genda Shigyō brewery founded in the early 17th century, claim a more solid continuity of activity precisely because they have never been absorbed.
We observe here a methodological debate: should we count the antiquity of a brand, an activity, or a legal entity? Depending on the criterion chosen, the ranking changes radically. To learn everything about the oldest company in the world, one must first resolve this definitional question.

Japanese Shinise: why Japan dominates the ranking of multi-century companies
Japan holds a remarkable proportion of very old companies. The term shinise refers to these companies with exceptional longevity, often family-owned, passed down over dozens of generations.
The Japanese Ministry of Economy (METI) formalized this specificity by launching a labeling program for “long-established companies” in the late 2010s. This program integrates shinise into the soft power and industrial tourism policy, following the “Cool Japan” campaigns accelerated after 2018.
The structural factors of this longevity
Japanese family transmission does not rely solely on biological lineage. The mukoyōshi system (adoption of a competent son-in-law) has allowed entrepreneurial dynasties to survive even in the absence of a qualified direct heir. This mechanism is absent in most European cultures, where transmission follows the bloodline.
- The mukoyōshi prioritizes competence over kinship, which prevents the gradual degradation of family management over several generations.
- Narrow sector specialization (temple construction, brewing, confectionery) limits the temptation for risky diversification that undermines many centenarian companies in the West.
- The culture of ie (house, lineage) places the sustainability of the business above the individual enrichment of its owners.
These three factors explain why Japan has several thousand shinise, while Europe only counts a few hundred comparable ones.
Multi-century European companies: foundations and trusts as shields for sustainability
In Europe, the extreme longevity of a company increasingly involves a partial conversion into a foundation or trust. This trend has intensified in recent years, particularly in luxury, publishing, and construction.
The principle is simple: remove capital from the classic inheritance logic and place it in a legal structure whose purpose is the sustainability of the activity. The foundation protects the company against inheritance disputes and hostile takeovers.
Notable examples of this strategy
Saint-Gobain, founded in 1665, illustrates another model of survival: the gradual transformation of a royal manufacture into a publicly traded multinational. The Compagnie de Saint-Gobain has survived the French Revolution, two world wars, and several major industrial restructurings. Its longevity is more due to its capacity for diversification than to a protective legal structure.
Mellerio dits Meller, a Parisian jeweler founded in 1613, represents the opposite case: a company that has remained family-owned for over four centuries, whose survival relies on direct transmission and a loyal clientele over several generations.
Ranking criteria for the oldest companies: methodological pitfalls
Rankings of the oldest companies in the world suffer from recurring biases that we recommend keeping in mind.
- The claimed founding date does not always correspond to a continuous commercial activity. Some companies have periods of interruption lasting several decades.
- Mergers and acquisitions blur the reading: a subsidiary is not an independent company, even if it retains the original name.
- Historical documentation is uneven across regions. Japan has exceptionally well-preserved commercial archives, which mechanically advantages Japanese companies in the rankings.
- Some European companies claim founding dates linked to royal charters or ecclesiastical privileges, without proof of actual commercial activity at those dates.
The study published by Business Financing, which maps the oldest companies by country, relies on declarative data that can sometimes be difficult to verify for periods prior to the 16th century.
The Weihenstephan brewery in Germany, whose founding is dated to 1040, is regularly contested: some historians argue that the documented brewing activity only dates back to the 15th century, with the date of 1040 corresponding to the founding of the monastery, not the brewery itself.
The title of “oldest company in the world” thus remains an open question, dependent on the criteria chosen. Legal continuity, family transmission, and uninterrupted commercial activity are three lenses that produce three different rankings. Kongō Gumi retains the top spot in collective memory, but its loss of independence in 2006 has opened a debate that the community of business historians has yet to resolve.
