Understanding the Layers of Information: The Importance of Primary, Secondary, and Tertiary Sources

 It's often said, "Seeing once is better than hearing a hundred times." But are we all making proper use of primary, secondary, and tertiary information?

Primary Information → Information and experiences directly encountered through your own senses. Secondary Information → Indirect information obtained from a specific source, like stories heard from acquaintances or from books with clear authorship. Tertiary Information → Information from unspecified sources, like information found online or through rumors.

This is the general idea.

I make it a point to trust primarily firsthand information. The reason is that secondary and tertiary information is invariably colored by someone's perspective.

For instance, "I was treated so badly by so-and-so!" Hearing this alone might make it seem terrible, but the original context could have involved rude behavior towards that person. There's a lack of objective information.

"It's the norm in society" or "There's a rumor going around..." Moreover, information from unknown sources can obscure the essence of what's truly important.

Ideally, everything should be verified through firsthand information—seeing, touching, listening, experiencing for oneself—but sadly, given that there are only 24 hours in a day, this is not always feasible.

Therefore, it's crucial to get a sense of the landscape through secondary and tertiary information and then seek out primary information for matters of fundamental importance.

If not, being led by secondary or tertiary information without verifying the essentials can often lead to critical oversights in decision-making.


Especially the higher our position, the less we'll encounter firsthand information unless you actively seek it out.

And if you're flooded with firsthand information about less important matters, you'll end up with no time for what truly matters.

Determining what to verify personally and what to delegate is a key point that requires accurate judgment, essential for effective management.

Even if you're not in a management position at work, every person manages their own life, so ultimately, this becomes a crucial point for everyone.

No Regrets Later: Start Today

Image
 As more mid-career employees join our company, I’ve started to notice that many of them are now younger than me. I became the president at 30 years old, and for a long time, people called me a "young president." But now, I feel I’m entering a new phase—somewhere between mid-career and veteran. It’s the stage where energy and experience combine to create the best opportunities to make an impact. At this age, it’s common to reflect and think, “If only I had done that back then…” or “What would have happened if I had tried?” Of course, we can’t change the past. But we can use our past experiences to shape the future. Maybe you didn’t try something before because you were afraid of failure. Or maybe you didn’t have the confidence. But it’s never too late to take action. What matters is starting now—so we don’t look back two or three years from now with the same regrets. If you feel regret but don’t take action, you only create a habit of inaction. On the other hand, the so...

Facing Fear and Seeking Growth

Image
 Some of you may already know this, but I make it a habit to read 10 to 15 books every month. It’s not so much a hobby—rather, I feel uneasy if I’m not constantly exposing myself to new ideas, disciplining my mind, and learning with hunger and intention. It might sound unpleasant to some, but in reality, having a strict boss or senior colleague who constantly tells you, “This is not good enough!” is a privilege. I don’t have that in my current position. No one tells me what’s right or wrong. And even if someone did, their “right” isn’t necessarily my right. So, I’m always on a journey to find my own answers—that’s what life is for me. In a book I read last week, there was a line that really struck me: “Success lies on the opposite side of fear.” It doesn’t just refer to financial success. True success—real achievement—exists only beyond what we fear the most. This reminds me of what we often say at Hattori Way: “Step outside your comfort zone!” But this quote is even sha...

What is the "Kinoko Management" style for Hattori??

Image
 As the season for warm, hearty meals approaches, mushrooms— kinoko in Japanese—frequently appear in dishes like hot pots. I personally love maitake mushrooms, although “mushroom” is how we refer to them in English. Interestingly, we intentionally call our management style Kinoko Management in English as well, keeping the unique essence of this concept. Mushrooms are not vegetables but fungi. Their defining role is in promoting decomposition, enabling the cycle of life to continue. What we see above ground—the mushrooms themselves—is just the tip of the iceberg. Below the surface lies the expansive mycelium network , an intricate web that connects mushrooms and plants, instantly sharing information and nutrients. Without fungi, the world would be overwhelmed by dead plants and animals. Thanks to their work, living organisms return to the earth, becoming nutrients that sustain new life. Mushrooms come in countless varieties. They differ in size, shape, and color—some are vibrant ...
