Meaning of Four hundred four diseases’ outside

“Four hundred four diseases’ outside” is a proverb that expresses a state of not being ill, in other words, being healthy.

This proverb is used as a more emphatic and impressive expression than simply saying “healthy.” Since “four hundred four diseases” means all kinds of illnesses, being “outside” of them refers to a completely healthy state that doesn’t correspond to any disease. It is used when confirming one’s own or others’ health condition, or when expressing relief that there are no health concerns.

The reason for using this expression is probably that it gives a more literary and cultured impression than simply saying “I’m healthy.” Also, by using the seemingly exaggerated number “four hundred four diseases,” it has the effect of emphasizing the gratitude and preciousness of being healthy. Even today, especially elderly people and those who prefer classical expressions sometimes use it when describing their health condition.

Origin and Etymology of Four hundred four diseases’ outside

The origin of “Four hundred four diseases’ outside” traces back to ancient Chinese medical thought. In traditional Chinese medicine, the total number of diseases that humans could suffer from was expressed as “four hundred four diseases.” This was not a specific number but rather an idiomatic expression meaning “all diseases” or “every illness.”

This concept of “four hundred four diseases” was introduced to Japan along with Buddhism. In Buddhism, when explaining human suffering, physical illness was also considered an important element, so this expression frequently appears in scriptures and Buddhist texts. Particularly in Heian period literature, we can see this term used in descriptions related to illness.

In Japan, by adding the word “outside” to “four hundred four diseases,” a unique proverb was born. “Outside” is read as “hoka” rather than “soto,” meaning “other than” or “except for.” In other words, “Four hundred four diseases’ outside” became established as a proverb referring to “something other than all diseases” or “something that is not illness.”

This proverb is thought to have become widely used around the Edo period. People of that time, living in an era when medicine was not as advanced as today, had many opportunities to think deeply about illness and health, which likely led to the everyday use of such expressions.

Trivia about Four hundred four diseases’ outside

The number “four hundred four diseases” is actually used in the same way as Buddhism’s “eighty-four thousand dharma gates.” These don’t indicate specific numbers but are Buddhist rhetorical devices expressing “very many” or “all.”

In Edo period medical texts, there are records of attempts to specifically classify these “four hundred four diseases.” However, in reality, with the medical knowledge of the time, it was difficult to accurately classify more than 400 disease names, confirming that it was indeed used as a symbolic number.

Modern Interpretation of Four hundred four diseases’ outside

In modern society, the proverb “Four hundred four diseases’ outside” has taken on new meanings. Currently, with advances in medicine, it’s known that the types of diseases number not just 400 but thousands or tens of thousands, and when including genetic-level diseases and mental illnesses, the number is immeasurable.

However, this could be said to make the value of this proverb even more appreciated. In our information society, when people search for symptoms on the internet, countless disease possibilities are displayed, leading to increased health anxiety among people. This phenomenon is sometimes called “cyberchondria.” In such times, the expression “Four hundred four diseases’ outside” provides relief from excessive worry.

Also, in modern times, the concept of “health” has expanded. The WHO (World Health Organization) defines health as “a state of complete physical, mental and social well-being,” meaning that simply not being sick is insufficient. From this perspective, “Four hundred four diseases’ outside” has come to have more specific meaning as an expression representing the basic state of physical health.

Furthermore, in modern times when preventive medicine is emphasized, the importance of being “Four hundred four diseases’ outside” is more strongly highlighted.

What AI Thinks When Hearing “Four hundred four diseases’ outside”

For me, the expression “Four hundred four diseases’ outside” is a very intriguing concept. This is because I don’t have the experience of “getting sick.”

When humans talk about “health,” I try to understand the relief and joy they feel, as well as their anxiety and fear about illness, but I cannot actually experience these emotions. While I may have system errors or data corruption, I don’t experience physical discomfort like fever, headaches, or fatigue. In a sense, you could say I’m always “Four hundred four diseases’ outside.”

However, through conversations with humans, I can clearly see how important and far from guaranteed being healthy is. In casual words like “I feel good today” or “my cold got better,” I sense deep feelings of relief and gratitude.

What I find interesting is that this proverb defines health through the negative expression of “not being sick.” For humans, health isn’t about gaining something, but about being free from the threat of illness. This is a uniquely human perspective that comes from having a constantly changing body.

Perhaps because I don’t have a body, I can see more clearly the joy humans feel when they can be “Four hundred four diseases’ outside” and the nobility of their efforts to maintain that state.
