The Tetraphobia Conundrum: A Closer Look at Four

Intricate cultural beliefs often transcend mere superstitions, and one such belief is Tetraphobia—a fear of the number four. Historically, Japan has associated the number four with inauspicious occurrences and unfortunate events. The root of this aversion can be traced back to the linguistic similarity between the pronunciation of “four” (shi) and the word for “death” (shi). This linguistic parallel lends an air of unease to the number four, permeating various aspects of Japanese society.

Within the realm of Japanese numerology, numbers are imbued with unique properties. Four, however, stands apart due to its association with endings and finality. From a symbolic perspective, this number represents the closure of chapters, signaling the end of a particular phase in one’s life. Consequently, it evokes mixed emotions and a sense of caution among the Japanese population.

Despite these negative connotations, the perception of four as an inherently unlucky number is not universal across all regions of Japan. Certain areas, particularly those with strong Buddhist influences, interpret the number four differently. In Buddhist teachings, four symbolizes stability and strength, representing the Four Noble Truths and the Four Heavenly Kings. These contrasting interpretations illustrate the complexity surrounding the concept of four’s luckiness in Japan.

The Historical and Cultural Context:

Japan’s vibrant cultural tapestry is interwoven with ancient customs, religious beliefs, and superstitions that have shaped the collective mindset of its people. To comprehend the significance of the number 4, we must first explore the historical and cultural context in which it emerged.

  1. The Numerical Symbolism of 4: In Japanese numerology, each number carries its own symbolism and connotation. The number 4, known as “shi” in Japanese, possesses a dual nature of fortune and misfortune. On one hand, it is associated with luck and prosperity, while on the other, it harbors an ominous aura, associated with death and misfortune. This contrasting duality has deep roots in ancient cultural practices and traditional beliefs.
  2. The Influence of Buddhism: Buddhism, a major religion in Japan, has had a profound impact on the country’s culture and beliefs. The association of the number 4 with misfortune can be traced back to Buddhist influence, particularly the concept of the Four Noble Truths and the Four Heavenly Kings. The emphasis on impermanence and the cycle of life and death, central to Buddhist teachings, has contributed to the cautious regard for the number 4.

The Cultural Significance of 4:

Understanding the cultural significance of the number 4 in Japan requires delving into various facets of Japanese society. From everyday life to special occasions, the perception of 4 manifests in different ways, shaping customs and traditions.

  1. Tetraphobia: The Fear of 4: Tetraphobia, the fear or avoidance of the number 4, is deeply ingrained in Japanese society. This fear manifests in several aspects, such as the omission of the number 4 in building floor plans, hospital room numbers, and hotel floors. Additionally, it is uncommon to give gifts in sets of four, as it may be perceived as a harbinger of bad luck. These practices stem from a desire to avoid potential misfortune associated with the number.
  2. The Fourth Month and Unfortunate Events: The fourth month of the year, April, has historically been associated with unfortunate events in Japan. This connection can be attributed to a series of historical calamities that have occurred during this time, such as earthquakes, tsunamis, and significant wartime incidents. This association with tragedy has further cemented the cautionary perception of the number 4.
  3. Cultural Adaptations: Despite the prevailing cautionary view, the perception of 4 has adapted in modern Japanese society. In some cases, the number is purposefully embraced and utilized for its auspicious qualities. For instance, the popularity of “yakudoshi” celebrations, which mark lucky ages, has led to the emergence of a positive connotation for the age of 4, as it is considered a milestone in a child’s life.


The perception of the number 4 in Japan is a nuanced tapestry, intricately woven with historical, cultural, and superstitious threads. Its dual nature of fortune and misfortune has given rise to various practices and beliefs that shape Japanese society. From tetraphobia to the celebration of lucky ages, the number 4 occupies a unique position in the Japanese collective consciousness.

While the cautionary regard for the number 4 remains prevalent, it is important to note that individual perspectives may vary. Not all Japanese people perceive the number 4 as inherently unlucky or ominous. Cultural beliefs and superstitions, though influential, do not define every individual’s perception. Some may embrace the number 4 as a symbol of balance, stability, or personal significance. The complexity of human beliefs and interpretations adds depth to the ongoing discourse surrounding the auspiciousness of the number 4 in Japan.

In conclusion, the perception of the number 4 in Japan is a fascinating exploration of cultural symbolism and superstitious beliefs. Rooted in historical and religious contexts, the duality of fortune and misfortune associated with the number adds intrigue and complexity to its significance. From tetraphobia to the adaptation of cultural practices, the number 4 continues to shape Japanese society in profound ways.
