Nihachigatsu ni omou kofune ni norisuru na
Meaning of “Don’t board a boat with a captain who thinks of his child in February and August”
This proverb warns against putting your beloved child on a boat during the second and eighth months of the lunar calendar. These months are dangerous because the seas become rough and unpredictable.
These periods mark seasonal transitions when weather changes suddenly. At sea, the danger increases dramatically during these times.
The teaching is clear: to protect a precious child’s life, you should avoid sea travel during dangerous periods, even if you have important business.
Today, boat travel is no longer part of daily life. But the essence of this proverb remains universal: “Don’t expose what’s precious to unnecessary danger.”
It teaches the importance of recognizing when risks increase. It reminds us to prioritize the safety of what we must protect.
This saying embodies parental love and responsibility. It also reflects a humble attitude toward nature’s power.
Origin and Etymology
The exact literary origin of this proverb is unclear. However, it clearly reflects Japan’s maritime culture and the seasonal awareness of the lunar calendar.
The second and eighth lunar months correspond roughly to March-April and September-October in the modern calendar. These periods mark seasonal transitions.
At sea, weather becomes particularly unstable during these times. They overlap with spring storms and typhoon season. Sailors have long considered these periods dangerous.
“Omou ko” means a beloved child, a precious son or daughter. During the Edo period, maritime shipping was central to distribution. Many people traveled by boat.
But the dangers of sea travel were incomparably greater than today. Voyages during rough seasons were life-threatening.
This proverb likely emerged from this maritime society. It taught that parents should prioritize their children’s safety above all else.
It’s more than a navigation warning. It’s a saying about parental love and caution that has been passed down through generations.
This proverb combines seasonal wisdom with family love. It reflects Japanese life and culture.
Interesting Facts
There are meteorological reasons why the second and eighth lunar months have rough seas. The second lunar month falls in March-April of the modern calendar.
This is spring storm season when low-pressure systems develop easily. The eighth lunar month falls in September-October, overlapping with peak typhoon season.
Our ancestors lacked scientific knowledge. Yet through years of experience, they accurately identified dangerous periods.
Sea travel during the Edo period was harsher than modern people can imagine. Ships were mainly sailboats without engines. They were completely at the mercy of weather.
Shipwrecks were not uncommon. Voyages during rough seasons required life-or-death decisions.
Usage Examples
- Taking my grandchild on a boat trip in the second lunar month? Don’t board a boat with a captain who thinks of his child in February and August, they say.
- We should avoid sailing during typhoon season. Don’t board a boat with a captain who thinks of his child in February and August, right?
Universal Wisdom
This proverb contains universal wisdom about “wise caution” needed to protect what we love.
Humans have two opposing qualities. One is the courage to face difficulties. The other is the caution to avoid danger.
We tend to praise courage. But to truly protect what matters, we sometimes need caution more than courage.
A parent’s instinct to protect their child is a fundamental force that has kept humanity alive. What’s interesting is that this proverb doesn’t say “don’t board boats” absolutely.
It specifies “in February and August.” This shows wisdom in accurately assessing risk, not excessive worry.
In modern society, we constantly face risks. New challenges always involve risk. But not all risks are equal.
We need the ability to distinguish risks we can avoid, risks we can reduce, and risks we must accept.
This proverb has been passed down because it teaches a fundamental human desire: to protect what we love. It also teaches the cool judgment needed for that protection.
The balance between courage and caution is true wisdom.
When AI Hears This
The second and eighth lunar months are when Earth’s climate system undergoes “phase transitions.” Phase transition means when a system’s state changes dramatically, like water becoming ice or steam.
Around the spring and autumn equinoxes, the sun’s angle changes rapidly. This makes atmospheric temperature distribution unstable. The weather system enters a critical state where “it could go either way.”
In this critical state, small changes trigger unpredictable large changes. For example, a slight pressure change can suddenly produce violent winds.
In complexity science, this is called the “butterfly effect.” Even modern weather forecasting has noticeably lower accuracy during these periods.
Statistically, rapid low-pressure development occurs most frequently around the equinoxes in Japanese waters.
What’s interesting is that this proverb limits itself to “kofune” – small boats. Wave energy that a large ship can absorb can capsize a small boat.
In other words, system vulnerability and environmental instability multiply to increase danger. Modern risk management theory calls this “nonlinear interaction between system vulnerability and environmental variation.”
Japanese fishermen understood this universal physical law through experience. They had no knowledge of meteorology or complexity theory.
Their insight was that when the environment is unstable, system robustness determines life or death.
Lessons for Today
This proverb teaches you “strategic patience” to protect what matters.
When we try to accomplish something, we tend to focus only on moving forward. But to achieve goals while protecting what’s truly important, we sometimes need the courage to stop and assess timing.
Modern society values speed. Quick decisions and quick actions are demanded. But isn’t distinguishing when to hurry and when to wait true wisdom?
Important relationships, health, career choices. If you have something to protect, waiting until conditions are right is also a valid decision.
This proverb isn’t telling you to be timid. Rather, it teaches you to have the strength to identify what’s truly important and calmly assess situations to protect it.
When the stormy season passes, the sea becomes calm. Your life also has times to advance and times to wait.
Those who can make this distinction are the ones who can reach their destination while protecting what matters.
