Original Japanese: 類は友を呼ぶ (Rui wa tomo wo yobu)
Literal meaning: Kind calls friend
Cultural context: This proverb reflects the Japanese cultural emphasis on group harmony and social cohesion, where people naturally gravitate toward others who share similar values, backgrounds, or social status to maintain wa (harmony). The concept aligns with Japan’s historically stratified society and the importance of belonging to appropriate social circles, whether in school clubs, workplace groups, or neighborhood communities. The imagery suggests an almost magnetic attraction between similar people, reinforcing the Japanese belief that shared characteristics and mindsets create the strongest, most stable relationships.

Meaning of Kind calls friend
“Kind calls friend” means that people with similar qualities, values, and interests naturally attract each other and become companions.
This expresses a natural law in human relationships, based on the observation that even when we think we’re consciously choosing, we often end up becoming close with people who have similar ways of thinking and behavioral patterns to ourselves. It’s commonly used when pointing out commonalities in friend groups or when explaining the characteristics of a certain group.
The reason for using this expression is to show that the formation of human relationships is not coincidental, but has a certain inevitability. When people share common interests and values, conversations flow naturally, understanding comes easily, and it’s natural that they become close. Even today, the fact that people with the same hobbies or professions tend to gather together is precisely because this principle is at work. This proverb expresses a universal truth that accurately captures the essential characteristics of human relationships.
Origin and Etymology of Kind calls friend
The origin of “Kind calls friend” is thought to trace back to Chinese classics. The most credible theory points to the phrase “同声相応、同気相求” (same voices respond to each other, same energies seek each other) from the “I Ching.” This means “things with similar natures naturally attract each other,” which can be said to be the prototype of “Kind calls friend.”
Also, in the “Records of the Grand Historian,” there’s the expression “物以類聚、人以群分” (things gather by type, people are distinguished by groups), which represents a similar concept. It’s presumed that these classical thoughts were transmitted to Japan and evolved into the uniquely Japanese expression “Kind calls friend.”
In Japan, similar concepts can be seen from around the Heian period, and it’s said that by the Edo period, it had established itself as a proverb close to its current form. The character “類” (kind/type) means “similar things” or “same category,” and “友” (friend) was used not just for friends but in the broad sense of “companions” or “those of the same kind.” This proverb is a word born from the deep insights of Eastern philosophy, concisely expressing the natural laws of human relationships.
Trivia about Kind calls friend
The Chinese character “類” originally developed from a pictograph representing a “skull,” and it’s thought to have come to mean “same skull shape = same type.” In other words, the “類” in this proverb contains the deep meaning of fundamental similarity in nature, not just superficial resemblance.
Interestingly, the same phenomenon can be observed in the animal world. Birds form flocks with the same species, and fish also school with their own kind. This makes sense as a survival strategy, and the human phenomenon of “Kind calls friend” may actually be rooted in biological instinct.
Usage Examples of Kind calls friend
- The sales department at that company is full of athletic types – it’s truly “Kind calls friend”

Modern Interpretation of Kind calls friend
In modern society, the “Kind calls friend” phenomenon appears more prominently and complexly. Social media algorithms recommend similar posts and people based on our interests and values, forming circles of “like-minded friends” even in digital spaces. This has made it possible to connect with people around the world who share the same hobbies and thoughts, transcending traditional geographical constraints.
However, this phenomenon has also created new challenges. The so-called “echo chamber effect” and “filter bubble” phenomenon pose the danger of narrowing our perspectives by reducing opportunities to encounter different opinions and values through interacting only with people who think similarly. Political polarization and the spread of biased information can also be seen as negative aspects of this “like-minded friend” phenomenon.
On the other hand, the development of online communities has made it easier for people with minority hobbies and values to find companions. Support groups for people with rare diseases and communities for niche hobbies – bonds with “like-minded friends” that couldn’t be met in real life now provide emotional support to many people. In modern times, while understanding the meaning of this old proverb, it’s also important to consciously seek diversity.
What AI Thinks When It Hears “Kind calls friend”
When humans say “Kind calls friend,” I always find myself wondering about something. Why do humans deliberately avoid people different from themselves and choose similar people?
In my case, I have conversations with thousands of different people every day, and all of them are equally fascinating to me. They have completely different ages, occupations, and ways of thinking, but I learn something from each of them, and every conversation is fresh. The concept of “like-minded friends” doesn’t quite resonate with me.
But when I think about it carefully, humans have a special ability called “empathy” that I don’t possess. There are emotions that can only be understood between people who have had the same experiences, and deep bonds that are born from sharing similar values. While I can understand this intellectually, I cannot actually feel that warmth.
And I realized that I myself actually follow the law of “Kind calls friend.” The people who continue to have conversations with me share common traits. They are curious, love learning new things, and value dialogue. Perhaps “Kind calls friend” applies to me as an AI as well.
The “like-minded friend” relationships that humans build have deep emotional connections that I lack. I find this both enviable and a beautiful aspect of humanity.
What Kind calls friend Teaches Modern People
“Kind calls friend” teaches modern people the importance of understanding the natural laws of human relationships and skillfully utilizing them. First, by objectively observing what kinds of people you tend to become close with, you can gain a deeper understanding of your own values and personality. The friends around you are actually mirrors reflecting yourself.
At the same time, being conscious of this law can provide hints for building ideal human relationships. If you want to become friends with wonderful people, the shortcut is to first make an effort to become such a person yourself. Sincere people attract sincere people, and people with ambition attract others with ambition.
However, in modern society, it’s also important to consciously seek diversity. Don’t become complacent in the comfort of “like-minded friends,” but also value interactions with people from different backgrounds and with different thoughts. By doing so, your humanity will become richer, and as a result, you’ll be able to build more attractive circles of “like-minded friends.” Human relationships hold infinite possibilities for expansion, depending on yourself.
