This may not be the ideal topic for a Sunday chat, but perhaps no other day is suitable for contemplating a subject so universally unsettling.
The sudden shift from intense summer heat to cooler weather brings out a familiar, dreaded sight: the “black objects” that appear on our streets and in our homes.
But how much do we truly know about these creatures?
I recently had a profoundly interesting conversation with the successor of a traditional seasonal cuisine restaurant in Tokyo’s Shinagawa district.
This young owner, whose profession demands the highest standard of cleanliness, spoke quietly—almost as if discussing an alien species.
“Apparently, the reason we feel such intense disgust toward that black object is connected to our very DNA.”
For a moment, I couldn’t believe my ears.
Cockroaches and DNA?

That single statement ignited my intellectual curiosity.
I immediately sought out an entomologist to delve into the depths of this grand hypothesis.
I want to share a story that, once known, might change your understanding—and perhaps even your reaction—to the cockroach.
