Japan has roughly 39,000 registered CPAs.
ACCA — the Association of Chartered Certified Accountants — has more than 257,900 members.
That is roughly 6.6 times the number of Japanese CPAs.
These are not directly comparable qualifications. Their examinations, experience requirements, professional roles and regulatory frameworks differ.
But the difference in scale highlights something we often overlook when evaluating professional qualifications:
Network size matters.
Living in Malaysia has changed the way I think about this.
In Japan, professional credentials are often judged primarily by difficulty.
How hard is the examination?
How many years does it take to pass?
What percentage of candidates succeed?
These are reasonable questions.
But there is another question that may matter just as much:
How portable is the qualification?
A Credential Is Also a Network
A professional qualification looks like an individual achievement.
But economically, it is also membership in a network.
The examination is only the entrance mechanism.
The real asset includes everything surrounding it: employer recognition, professional standards, training infrastructure, alumni, institutional relationships, and compatibility with other markets.
This resembles the network effects we normally associate with technology.
A payment system becomes more useful as more merchants accept it.
A language becomes more useful as more people speak it.
A professional qualification can similarly become more useful as more employers, regulators and institutions understand what it represents.
This is why the difference between roughly 39,000 Japanese CPAs and 258,000 ACCA members is interesting.
The numbers do not tell us which qualification is better.
They tell us something about the scale of the networks in which those qualifications operate.
Difficulty Is Not the Same as Value
We often assume that harder qualifications should be more valuable.
But that does not necessarily follow.
Imagine two qualifications.
Qualification A requires enormous effort but is primarily recognized within one country.
Qualification B may require a different level or type of effort, but is widely understood by employers and institutions across many markets.
Which is more valuable?
There is no universal answer.
For someone planning to spend an entire career in one country, the domestic qualification may clearly be the better choice.
But for someone whose career might move between Kuala Lumpur, Singapore, Dubai, Hong Kong or London, the calculation changes.
Difficulty is only one variable.
I increasingly think about professional qualifications through four factors:
Difficulty × Recognition × Portability × Market Size
A qualification that performs strongly across all four dimensions can create a very different set of opportunities from one optimized primarily for a single domestic market.
Japan Built Deep Systems. Britain Built Wide Ones.
Japan created extraordinarily sophisticated domestic systems.
Its universities, professional examinations, corporations and regulatory institutions developed to function within one of the world’s largest and most advanced economies.
For decades, that was an enormous advantage.
And Japanese professional qualifications remain extremely valuable in the markets for which they were designed.
But specialization can also create limits when careers become international.
A qualification that is immediately understood in Tokyo may require considerably more explanation in Kuala Lumpur or Dubai.
British-rooted qualifications developed within a very different historical network.
Britain once governed territories around the world. English, common law, educational structures and professional institutions spread internationally.
The political empire disappeared.
But many of those institutional connections remained.
More importantly, many continued to expand.
Professional qualifications are one manifestation of that legacy.
ACCA is an especially interesting example because it has evolved far beyond Britain itself. Its membership today is international, and its institutional network extends across a large number of markets.
That does not mean British qualifications are inherently better.
It means some of them operate within unusually wide international networks.
And networks compound.
The Educational Arbitrage
This creates what I think is an interesting form of educational arbitrage.
People naturally compare credentials by prestige and difficulty.
But perhaps another comparison deserves more attention:
Effort required to acquire the credential versus number of opportunities the credential can potentially access.
A qualification that is exceptionally difficult but geographically concentrated may offer a very different return on invested time from one that can travel across multiple labor markets.
Again, this does not mean everyone should choose the international qualification.
A Japanese accountant planning to spend an entire career practicing regulated accounting in Japan has very different requirements from someone building an international career.
Local expertise has enormous value.
But for young people who genuinely do not know where they may live or work twenty years from now, portability has economic value.
The same applies to parents thinking about their children’s education.
The future location of a career is increasingly difficult to predict.
Tokyo today.
Singapore ten years from now.
Dubai after that.
Or perhaps somewhere we are not currently considering at all.
In that environment, a portable qualification preserves options.
And the younger you are, the longer those options have to compound.
Portability Is Optionality
This is ultimately why I find the comparison between Japanese CPAs and ACCA interesting.
The headline numbers — roughly 39,000 versus 258,000 — are not a ranking of the two qualifications.
They illustrate two different types of professional ecosystems.
One developed within a deep and sophisticated domestic market.
The other developed across a much wider international network.
When evaluating a qualification, perhaps the most interesting question is therefore not simply:
How hard is it to obtain?
But:
How many doors can it open once you have it?
Difficulty matters.
Prestige matters.
Technical competence certainly matters.
But network size and portability matter too.
Portability is a form of optionality.
And optionality has value.
