Causes foreigners to think Japanese people have bad breath

HEALTH

Japanese people are concerned about the body odor of foreigners, but conversely, foreigners are concerned about the halitosis of Japanese people.

Apparently, there is an image that Japanese have little body odor but bad breath.

In this article, we will thoroughly analyze the reasons why such an image is formed.
In addition, we will examine a wide range of topics, including Japanese people’s awareness of halitosis, the current state of countermeasures, and suggestions for the future.

Foreigner’s Review and Experiences of Japanese Halitosis

This is not limited to Japanese people, but just a reference that there are opinions like this.

  • When riding a crowded train, I often feel my uncle’s bad breath. Sometimes I can’t stand it and get off at the next station.
  • When talking with a Japanese business partner in a business meeting, I could not concentrate because I was bothered by his bad breath.
  • When I pointed out my bad breath to my Japanese friend, he was very surprised and shocked.
  • I went on a date with a Japanese woman, but I hesitated to kiss her because of her bad breath. I did as a result, though.
  • I feel that Japanese people have low awareness of bad breath care.
  • Japanese probably don’t even notice their own bad breath.

Reasons why Japanese are often thought to have bad breath.

Oral care habits

In Western countries, brushing and flossing the teeth at least twice a day is recommended.
However, most Japanese brush their teeth only once a day, and those who floss are in the minority.
The rate of regular checkups is also lower than in Western countries, indicating a difference in awareness of oral care.

  • Brushing once a day does not adequately remove plaque and tartar, which causes bad breath.
  • By not flossing, stains accumulate between the teeth and in periodontal pockets, causing bad breath.
  • By not receiving regular checkups, diseases that cause bad breath, such as tooth decay and gum disease, are not detected and treated early.

Dietary habits

Compared to Western countries, the Japanese diet is characterized by a high use of seafood and spices, which tend to produce volatile sulfur compounds that cause halitosis.
They also snack more frequently than Western countries, which may cause bad breath to persist for a longer period of time.

  • Trimethylamine oxide (TMAO) in seafood is decomposed by intestinal bacteria into volatile sulfur compounds (VSC), which cause halitosis.
  • Allyl sulfide in spices is a type of volatile sulfur compound that causes halitosis.
  • Snacking between meals leaves food debris and sugar in the mouth, causing bacteria to proliferate, resulting in bad breath.

*This varies greatly from person to person.

Other factors

Stress, smoking, aging, and dry mouth can also cause bad breath.
In recent years, more and more people suffer from stress-induced halitosis in Japan, which is known as a stressful society.
In addition, with the aging of the population, age-related halitosis is also on the rise.

  • Stress: Stress hormones decrease saliva secretion, causing oral dryness and resulting in halitosis.
  • Smoking: Toxic substances in cigarette smoke deteriorate the oral environment and cause halitosis.
  • Aging: Decreased saliva production causes oral dryness, resulting in halitosis.
  • Oral dryness: Decreased saliva secretion and self-cleansing of the mouth, resulting in halitosis.

Awareness of halitosis among the Japanese and the current situation

Past surveys have shown that about 80% of Japanese are interested in halitosis care.
However, only about half of the respondents actually take measures to prevent halitosis, indicating a gap between awareness and action.

  • About 80% of respondents think that bad breath makes others uncomfortable.
  • About 70% are concerned about their own bad breath.
  • About 60% of respondents take some kind of action to take care of their bad breath.

In recent years, the market for halitosis prevention goods has been expanding, and interest in halitosis care is growing.
However, compared to Western countries, the percentage of patients visiting halitosis outpatient clinics is low, and the number of people receiving professional treatment is still small.

  • The market for halitosis prevention goods is worth approximately 10 billion yen per year.
  • The consultation rate at halitosis outpatient clinics is about 2%.
  • The number of dental clinics specializing in halitosis care is still small.

Can the halitosis problem among the Japanese be improved?

The problem of halitosis among the Japanese is caused by a complex interplay of dietary habits, oral care practices, and other factors.
Solutions will require increased awareness at the individual level and a society-wide commitment to halitosis care.
