Surviving a century does not guarantee surviving the next year. When you invest, you are buying future earnings, not past achievements.
In Japan, 112 businesses with at least 100 years of history went bankrupt through August.
According to Teikoku Databank, failures among these longstanding companies are running at a record annual pace.

Japan’s business traditions run deep. But even 100 years of success cannot guarantee a profitable future.

That should get the attention of anyone investing in established businesses.
A familiar name can make you feel comfortable owning its shares. But comfort does not pay dividends or increase the value of your investment.
What matters is whether the business can keep serving customers profitably. Its history deserves respect, but its future must earn our money.
That distinction sits at the heart of our American Prosperity approach.
We look for quality businesses with the strength to keep creating value. A company’s age tells us how long it has survived. Its ability to earn profits helps us judge what comes next.
3 Businesses That History Couldn’t Protect
Each survived for more than a century before its financial troubles caught up with it.
Sube Shoten, a Japanese tofu maker founded in 1877, stopped operating in May and began preparing a bankruptcy filing. It used carefully selected ingredients while operating on thin profit margins. When ingredient costs surged, those margins left little room to absorb the pressure. Nearly 150 years of history could not make the numbers work.
Kano Gumi, a construction business founded in 1925, entered bankruptcy in January. Previously undisclosed borrowing tied to property investments had come to light. Its troubles show why investors must examine financial obligations beneath a familiar name. A long history cannot compensate for debt that threatens survival.
Onobe Seikansho, a paper packaging manufacturer founded in 1901, entered bankruptcy in May. Inflated receivables and inventory were uncovered after more than a decade. Its experience shows why reported numbers deserve scrutiny. A proud history could not substitute for reliable financial reporting.
Thin margins, hidden debt, and unreliable accounting can overwhelm even a familiar name. The causes differed, but the lesson for investors is the same.
Study what keeps a business profitable today, not just how long it has existed.
Good Businesses Keep Adapting
Japan’s oldest businesses did plenty right for a long time.
They earned customers’ trust, spent carefully, and planned for future generations. Those habits helped them survive when other businesses disappeared.
But the costs of running a business keep changing. Ingredients become more expensive, workers get harder to find, and customers change their buying habits. A company can keep doing everything the same and still watch profits shrink.
That is when management needs to make smart changes. It might raise prices, buy equipment that saves time, or reach new customers. Each decision should help the business serve customers while protecting its ability to earn money.
Keeping customers happy means little if every sale leaves the business weaker.
A business needs enough profit to maintain equipment and invest in improvements. It needs financial strength to handle setbacks without putting its survival at risk.
Management must make those decisions before the company runs out of options.
As investors, we want leaders who recognize problems and act early. Experience becomes more valuable when management uses it to make better decisions.
What This Means for Our Portfolio
Before I recommend a business to you, I need to understand what keeps customers coming back. Then I study whether those sales produce lasting profits and usable cash.
I want to know whether debt remains manageable during difficult periods. I examine whether management invests wisely and reports its results honestly. Then I consider the price we would pay to own the shares.
Even an excellent business can become a disappointing investment at the wrong price.
That is how we approach opportunities in the American Prosperity Portfolio. We own businesses, so we study them through a business owner’s eyes.
A rising stock price alone can’t tell us whether a company is getting stronger. We keep reviewing the evidence behind our original investment thesis.
I remain optimistic about America because businesses have powerful reasons to keep improving. Customers reward useful products, better service, and solutions that save them money. Companies that meet those needs can create value over many years.
Our opportunity is to own a share of that progress. Finding those businesses takes more than recognizing a name or reading a headline.
It takes research into their earnings, leadership, financial strength, and the price we pay.
That is why I write the American Prosperity Report for you. I study the businesses, weigh the risks, and explain the opportunities worth your attention.
My goal is to help you turn America’s progress into lasting wealth.
