Mariko Aoki phenomenon is a Japanese term referring to an urge to defecate that is suddenly felt after entering bookstores. The phenomenon is named after Mariko Aoki, a woman who described this experience in a magazine article in 1985. The phenomenon has since become a topic of discussion and curiosity in Japan.

Origin

The term "Mariko Aoki phenomenon" originated from a letter written by Mariko Aoki to the magazine Hon no Zasshi (Book Magazine) in 1985. In her letter, Aoki described her experience of feeling an urgent need to defecate whenever she entered a bookstore. The magazine published her letter, and many readers responded with similar experiences, leading to the coining of the term.

Possible Explanations

Several theories have been proposed to explain the Mariko Aoki phenomenon:

• Psychological Factors: Some suggest that the phenomenon may be related to the relaxation and comfort people feel when surrounded by books, which could trigger a parasympathetic nervous system response.
• Physiological Factors: Others propose that the posture of browsing books, which often involves bending and squatting, may stimulate the digestive system.
• Environmental Factors: The smell of ink and paper in bookstores has also been suggested as a possible trigger.

Cultural Impact

The Mariko Aoki phenomenon has become a well-known cultural reference in Japan. It has been mentioned in various media, including television shows, radio programs, and books. The phenomenon is often discussed humorously, and it has even been the subject of scientific studies.

Related Phenomena

The Mariko Aoki phenomenon is similar to other situations where specific environments or activities trigger physiological responses. For example, some people experience an urge to urinate when they hear running water, a phenomenon known as the sound of running water effect.
