WARREN BUFFETT has finally answered a question that has long intrigued investors: What sparked his interest in five Japanese trading houses in , a bet that is now worth more than $25 billion?

The answer was hiding in plain sight: 鈥淚 was just going through a little handbook that probably had two or three thousand Japanese companies in it,鈥 he investors at the annual general meeting in Omaha, Nebraska, earlier this month, shortly before announcing his resignation as head of Berkshire Hathaway, Inc. 鈥淭here were these five trading companies selling at ridiculously low prices. So I spent about a year acquiring them.鈥

It鈥檚 the same screening methodology the typical Japanese retail trader uses. The 鈥渓ittle handbook鈥 is the Kaisha Shikiho, the 鈥,鈥 indispensable for the country鈥檚 stock-pickers. Released quarterly for 楼2,800 (around $20), the Shikiho is a thick, dictionary-sized guide listing facts and figures on every one of the country鈥檚 nearly 4,000 listed companies.

Buffett鈥檚 approval should have thousands of his acolytes flocking to the English version, known as the Japan Company Handbook and on his desk as far back as 12 years ago. But in a remarkable fumble, the publisher last year the English version, just months before the world鈥檚 most famous investor endorsed it.

Perhaps that makes it harder to find stock gems, giving an advantage to the patient investor that he has long championed. Fortunately, it鈥檚 not the only lesson on investing in Japan he imparted. Until now, Buffett has largely let his money do the talking 鈥 but recent remarks reveal lessons on investing there that more should know.

REALIZE THE OPPORTUNITY
鈥淭im Cook would tell you that iPhone sales there are about as great as any country outside the United States. American Express would tell you that they sell their product very, very well in Japan. Coca-Cola, that we do business with, another big investment of ours, does extraordinarily well.鈥

While more people are paying attention to Japan these days, thanks to and inbound tourism, it remains in everything from its approach to demographics or healthcare, to the investing opportunities that abound.

And as Buffett notes, it鈥檚 a colossal market not just for iPhones and Coke but the second largest for music, the third largest for movies. Something as obscure as the pachinko gambling business generates 10 times the revenue of all the casinos in Las Vegas combined. Yet some combination of cultural barriers, the slow pace of change, or the existence of faster-growing neighbors, means it gets less attention than it deserves.

Andrew McDermott of Mission Value Partners, a longtime investor in Japan who Buffett sought advice from, explains how the Oracle became 鈥渋ncreasingly comfortable with Japanese companies and increasingly uncomfortable鈥 with the then-in-vogue China. In 2012, Buffett 鈥渞emarked that he鈥檇 rather invest in Japan than anywhere else in the world,鈥 McDermott in a blog post. And if that鈥檚 not enough, consider its position internationally: A strategically vital nation that advocates free trade and fair courts. These days, those are in short supply. Buffett suggested macro factors like another Bank of Japan rate hike wouldn鈥檛 dissuade him from investing further. Others should take note.

EMBRACE THE DIFFERENCE
鈥淭hey have some different customs than we have. They drink Georgia coffee as their number one Coca-Cola product. I haven鈥檛 converted them to Cherry Coke, and they鈥檙e not going to convert me to Georgia coffee. But it鈥檚 a perfect relationship.鈥

Georgia is a brand of canned coffee served in vending machines and convenience stores across the country. Cherry Coke is very occasionally available as a novelty. As Buffett suggests, to each their own: He understands what many who鈥檝e left the country frustrated do not: That Japan is its own place, and it鈥檚 these differences that make the country, and its firms, compelling.

The biggest stocks are successful not in spite of their idiosyncrasies, but because of them. Consider how Toyota Motor Corp. has defied investor pressure to shift to electric vehicles, becoming the five years running by focusing on hybrids. Or Nintendo Co., which faced down calls insisting it must abandon its own hardware and shift to mobile games; a decade and $100 billion in Switch sales later, the stock trades just off an all-time high. These firms might not put shareholders above all else, but they build lasting brands that reward the long-term investor.

DON鈥橳 EXPECT OVERNIGHT CHANGE
鈥淲e don鈥檛 have any intention of trying to change what they鈥檝e done because they do it very successfully. Our main activity is just to cheer and clap.鈥

A lengthy time window is crucial when it comes to Japan. While it doesn鈥檛 always need to be the decades Berkshire plans, expecting rapid change is a recipe for disappointment. To follow Buffett, the strategy is to find the good management teams and 鈥渃heer and clap,鈥 rather than lecture.

While Japan is becoming more receptive to outside shareholders, investors who work with management long term, rather than against them in a short investment period, still seem most likely to succeed. Consider Third Point LLC鈥檚 Dan Loeb. Had he just retained the 7% stake in Sony Group Corp. he held in 2013, Loeb could have turned $1.1 billion into more than $10 billion today 鈥 without doing anything.

Foreign investors can help by attracting attention to opportunities and explaining them abroad, something Japanese boards struggle to do (consider how few paid much attention to the trading houses before Berkshire.)

Investing in Japan isn鈥檛 for the faint of heart. But ultimately it can reward those who 鈥 like Buffett 鈥 turn every page.
