Why do Japanese princess have black teeth?

In the olden days, most married Japanese women, some aristocrats, samurai and even those people from the imperial would blacken their teeth as some sort of a symbol of stature and pedigree. This is because in Japan, black color and things were considered especially beautiful.

Ohaguro, according to Wikipedia, is a custom of dyeing one’s teeth black and an aristocratic term. It was practised since prehistoric times (traces of blackened teeth can be seen in the buried bones and haniwa from the Kofun period) and remained most popular in Japan until the Meiji era, as well as in the southeastern parts of China and Southeast Asia. Dyeing was mainly done by married women, though occasionally men did it as well. It was also beneficial, as it prevented tooth decay, in a similar fashion to modern dental sealants.

Here was a recorded argument discussing the “barbarism” of the dress and customary practices of different local peoples from “The Intrigues of the Warring States” Han Dynasty scholar Liu Xiang’s compilation of stories, speeches and historical records: Gongzi Cheng: “I have heard the Middle Kingdoms described as the home of all wisdom and learning, etc…. But now the king would discard all this and wear the habit of foreign regions. Let him think carefully, for he is changing the teachings of our ancients, turning from the ways of former times, going counter to the desires of his people, offending scholars, and ceasing to be part of the Middle Kingdoms.” Wuling: “Clothes exist to be useful and manners respond to conditions. Therefore the sage was guided by what was right and proper for each locality and encouraged behavior related to its conditions, etc… To crop the hair, decorate the body, rub pigment into arms and fasten garments on the left side are the ways of the Ba and Yue (southern barbarians). In the country of Daiwu* the habit is to blacken teeth, scar cheeks, and wear caps of sheepskin stitched crudely with an awl. Their costumes and customs differ but each derives benefit from his own… From Changshan to Dai and Shangdang, we border Yan and the Eastern Hu in the east, and Loufan, Qin, and Han in the west. Along this line we have not a single mounted archer. I change our garments and mount archers to guard our borders with Yan, the Eastern Hu, Loufan, Qin, and Han…. With men dressed as mounted archers I can today prepare for Shangdang nearby and exact vengeance upon Zhangshan at a distance….” Gongzi Cheng: “Such has been my stupidity that I have not even conceived of these arguments, your majesty. I had instead the temerity to mouth platitudes. But now that I too wish to carry out the hopes of Kings Jian and Xiang, the ambitions of our ancestral rulers, what choice have I but to make obeisance and obey your order?”

Note*Daiwu is in Guangdong, Southeast China.

In the Shan Hai Jing, there is also a description of a “black teeth country” (lit. 黒歯国) (Source: Wikipedia). Thus, the practice of blackened teeth was well known in China and right down to modern times today, teeth blackening similar to the Japanese ohaguro practice can be seen among many minority groups in Southeast Asia. The practice is dwindling among the younger women, but remains prevalent in older women among certain of the hill tribes. Teeth blackening was widely practised especially by various ethnic tribes in Southeast Asia. In 1938, a French survey found that 80% of Vietnamese in the countryside blackened their teeth. The Vietnamese women blackened their teeth through a tooth lacquering process (NOT by chewing betelnuts) and undergoing the ritual of having one’s teeth blackened indicated a girl was “grown up and ready for marriage.”(Source: Tooth Blackening: The Forgotten Tradition)

Teeth blackening has been recorded to be practised by these peoples:

In Yunnan: Hmong people, Lahu people, Yao people

In Vietnam: ethnic Vietnamese, Dao Tien people, Lu people, Black Hmong people, Nung people

In Laos: Hani people, Katu people, Phu noi people

In Thailand: Akha, Lisu people

In the Pacific Islands: the Philippines: Mariana Islands, Palau, Yap

The process

The main ingredient was a dark-brown solution of ferric acetate called kanemizu (かねみず), made by dissolving iron filings in vinegar. When the solution was combined with vegetable tannins from sources such as gallnut powder or tea powder, it would turn black and become non-water soluble, in the same manner that iron gall ink is produced. Coating the teeth with this liquid helped to prevent tooth decay and enamel decay. The dye had to be applied once a day or once every few days. As a convenient prescription, a fine powder of gallnut powder, sulfuric acid, and oyster shell could also be applied to the teeth, though this never really caught on. On February 5, 1870, the government outlawed the practice of ohaguro, so today, the only places where ohaguro can still be seen in Japan is in plays, hanamachi (geisha quarters), some matsuri, and movies. In theatrical plays, ink used to be mixed with turpentine was used, though these days, ink is mixed with tooth wax instead.

Interesting Japanese custom: Ohaguro or black teeth writes on the historical practice of ohaguro through the ages: Yellow teeth are a real turn off, but black teeth are a major turn on, for the ancient Japanese people at least. Ohaguro simple means to blacken the teeth. It is an old Japanese custom that was so popular centuries ago in Japan, and up to the Meiji period at the end of the 19th century. If you’re lucky enough, you could probably catch a glimpse of this black teeth phenomenon in Kyoto nowadays by Geisha ladies. In the olden days, most married Japanese women, some aristocrats, samurai and even those people from the imperial would blacken their teeth as some sort of a symbol of stature and pedigree. This is because in Japan, black color and things were considered especially beautiful.

The History of Black Teeth Make-up or Ohaguro

According to archeological researches done on ancient tombs and burial mounds somewhere in Japan, the custom of Ohaguro or blackening the teeth had existed since the prehistorical ages. Dictations of it were even included somewhere in the famous novel, Tales of Genji or Genji Monogatari and Tsutsumi Chuunagon Monogatari that were written in the Heian period and within the ukiyoe art of the Edo period. The term Ohaguro itself is a word used by the Japanese aristocrats. In Japan, it existed from ancient times, and it was seen among the civilians up until the end of the Meiji period.perhaps you’ll wonder why would the wife of the samurai would dyed their teeth black? Other than being thought as beautiful, other guesses include that they want to maintain dental health and protecting ugly tooth as such. Besides, a woman who has black teeth is obviously a married woman and no man should try to woe her.

Chronological Facts of Ohaguro:-

Heian period

(References to ohaguro exist in the Genji Monogatari and Tsutsumi Chuunagon Monogatari) Ohaguro was practiced by aristocratic men and women who have reached puberty and celebrated their genpuku or mogi, Tairas and other samurai, members of the imperial family who had finished their hakamaza, a ceremony where a child is fitted with a hakama and pages working at large temples. At this period, they even shaved off their eyebrow and painted their eyebrow instead. This tradition continues in the imperial family until the end of Edo period.

Muromachi period

Ohaguro was used among adults and also during political marriages, when a female child of the military commanders had their teeth painted black as a symbol of the coming of age. Even a commander who had been struck in the head and had distorted appearance would wear average womens’ makeup and would blacken their teeth to avoid appearing ugly.

Only the men of the imperial family and male aristocrats still practiced Ohaguro, but there are still practices of blackening the teeth among the common married women, unmarried women who are already pass their prime time, which is 18 years old as well as Geisha and prostitutes. For people who live outside main cities, this practice still existed during special celebration such as matsuri, wedding ceremonies and funerals.

Meiji Period

On February 5, 1870, the government banned the practice of ohaguro, and the process gradually became obsolete. Ohaguro was closely related to Japanese ghost (youkai) stories and urban legend. One famous story was Ohaguro Bettari. Ohaguro bettari beholds the image of a Japanese lady in a bridal kimono with blackened teeth or ohaguro but she also appeared with no other facial features or remarks, meaning no nose or eyes but a blank face with just black teeth shown, eeriely. You can say it is a like some sort of a typical ancient Asian female ghosts. It was also said that Ohaguro bettari haunts temple grounds and shrines during nighttime and distracting men with their seen beauty from behind but scares them away with their upfront features. But I guess, who would stop to have a second look at a female lady in bridal suits walking alone in a quiet and dark temple grounds at night right?!

:::

“The behavior of the Imperial family was also critical to adoption of western cultural practices. Before 1873 most Japanese women of a high social position would shave their eyebrows and blacken their teeth to appear beautiful. But on March 3rd 1873 the Empress appeared in public wearing her own eyebrows and with unblackened teeth. Following that day most women in Tokyo and around Japan stopped shaving their eyebrows and blackening their teeth.” “Ohaguro are the teeth dyed in black, which was the custom practiced in olden times, mainly by women. The black dye is an oxidized mixture of iron shavings melted in vinegar and powdered gallnuts. Around the ninth century, tooth blackening came into fashion among Heian court ladies and some men. In the Muromachi period (1336-1568), it became popular even among commoners and was done from the age of puberty. In the Edo period (1603-1868), married women were required to dye their teeth black. This custom is no longer practiced.”

From Japanese Teeth Blackening (Ohaguro) by Lawrence Lee:

Japanese referred their process of teeth blackening as Ohaguro. The Ohaguro trend began under the Heian Era (794 – 1192). The word Ohaguro is derived from the Japanese word, ‘kuro’ which “expresses darkness after the sunsets” (Fukagawa, 2008).In ancient times, night was considered as the “time when evil spirits rampant. Black was ill-omened and hated as a color which means to be wrong” (Fukagawa, 2008). However, the Japanese, whom practice Buddhism, referred black as an unchanging color for which cannot be dyed with another. “Color has many symbolic properties and is often adapted in many societies around the world” (“The black teeth,” 2010). The reason why one chooses a particular color have their own reason and meaning behind it. This is why Buddhism had a great influence and impact on choosing the color black because they believed it was a static color that visually symbolizes constant strength and dignity. What are Ohaguro’s made out of and how are they used? The Japanese have a unique way of handling and making the ingredients of Ohaguro. They have a large round container called ‘mimidarai’. Sitting on top of the container is a thin tray called ‘watashigane’. On top of the tray is the ‘kanewan’ which is the bowl that the dye is mixed. A feathered tip brush was used to paint the teeth, the brush stick is made of bamboo. A porcelain bowl was used as well as a small box of fushi powder. The fushi powder is made from the “gallnuts of the Japanese sumac tree…, and kanemizu, which was made by fermenting iron filing in an acidic mixture of tea, vinegar and rice wine” (“Ohaguro – beautiful,” 2011). Having all these ingredients mixed together, should produce a black dye which could then be applied to the teeth. Unfortunately doing this process will not make teeth blackening stay permanent. They would quickly fade and the whole process would have to be done again. It is a labor intensive work to start everything from scratch. Not only that, but also the dye emits a foul smell. The dye had to be applied once a day or once every few days depending on the color left intact to the teeth. According to the Japan times from the Japan Society of Aesthetic Dentistry, they believed the reason why they do teeth blackening was because “Ohaguro had the effect of protecting teeth from cavities and periodontitis” (Fukue, 2010). They also believed that this “technique could potentially prolong lives” (Davis, 2011). In the Heian Era (794 – 1192) Ohaguro became popular among males especially court nobles and commanders. Samurais also use Ohaguro as a custom to show proof of loyalty and that a samurai does not serve two masters within a lifetime. The custom is said to have ended around the Muromati Era (1558 – 1572). During the Edo Era (1603 – 1867), the practice was followed by women. Women blacken their teeth to enhance their appearance when they are ready to find a husband. At that time blackened teeth was a trend and was thought that it made the women look beautiful. It signified unity and fidelity. They possibly believed that teeth were a visible part of the skeleton, which as a symbol of death, was unclean. It was also thought to believe in the Buddhist idea that white teeth reveal the animal nature of men and women and that the civilized person should conceal them, thus using teeth blackening. Because of the use of Ohaguro, it was quickly spread all over the country and became the symbol of married women. Ohaguro was also used for unmarried women who already passed their prime time which is eighteen years of age, as well as Geisha and prostitutes. “The color of teeth reflects the social conceptions of beauty, social status and age” (Fukagawa, 2008). On February 5th of 1870, the government banned the practice of Ohaguro, and the tradition was ceased. There is not much of a difference when compared with Japanese and modern American ideal dentistry. Americans however, do not practice teeth blackening. They believed that exposing the color of the enamel and dentin part of the tooth is what makes us feel natural. The anatomical features of both cultures of the Japanese and Americans are the same. The Japanese didn’t make any modifications in its structure and function of their teeth. Judging the lack of dentistry provided in ancient Japan, they probably left their teeth the way it was grown. That means tooth alignment could be deformed. Although they lack dental practices, one painting from ancient Japan indicated practices of full and partial dentures. Americans today use full and partial dentures too however, if there is a slight deformation in tooth alignment, it can be guided back to its natural form with the help of braces. Japanese practices of teeth blackening are strict compared to Americans. Japanese teeth blackening help judge a person by rank, age, and marital status. Americans do not have such things. They leave their teeth natural as others would do the same. Despite the fact that Americans expose the color of the enamel and dentin part of the tooth, there is a trend now where bleach would bring up the whiteness of their teeth. They believe that bleaching their teeth would bring a whiter, brighter smile. Every billboard and advertisements you see in magazines and streets today deal with people smiling, exposing their white teeth. It attracts people, basically telling them that they can look younger and beautiful if they bleach their teeth. In every part of the culture, color plays a huge role. There is a reason why one would choose a particular color as opposed to the rest because they have their own reason and meaning behind it. When one finds doing something to their teeth can make them look beautiful, others would do it until everyone within the region does it as a practice. We can now tell that although Japanese practices of Ohaguro teeth blackening are different from the American teeth whitening by appearance, they all have one same goal; making themselves look beautiful.

Jomon and Ainu practices

Slightly different from the practised teeth blackening, according to Kirsten Refsing writing in Early European Writings on Ainu Culture: Travelogues and Descriptions (Volume 2), p. 16, Ainu women painted around their lips a dark blue black color as an indication of rank. The early Jomon peoples have so far not been found to have practised teeth blackening, though the custom of teeth ablation has been widely recorded for the Jomon period…parallel to practices by nearby temporal neighbours in southern Cambodia and northeast Thailand, suggesting a unique cultural behaviour for the region (“Cultural Modification of the Dentition in Cambodia“, K.M. Domett et al.).

Tooth Blackening – The Forgotten Tradition by Lanh Nyuyen

The Blackened Teeth of Traditional Vietnamese Tribes

Asia is a land full of weird and wonderful customs and rituals. Throughout the continent there are thousands of different traditions that remain alive and these customs often stem from religious beliefs that have been faithfully upheld for thousands of years. Trekking through the gentle mountains of Northern Thailand, Laos and Vietnam is a great way to experience these traditions first hand. A strangely interesting custom that is often misunderstood is the Vietnamese ritual of tooth blackening or tooth lacquering. Tooth blackening is not totally uncommon for Vietnamese people living traditional lives. Many tour guides still tell tourists the blackening is the result of chewing betel nut which isn’t entirely true. It is a mild stimulant that comes in the form of a tiny parcel made up of betel nut, the fruit of an Areca tree and lime paste wrapped in a leaf of the betel pepper vine. It is chewed in a similar way to tobacco and this stains the teeth. It is actually quite easy to spot the difference between blackened teeth and those stained by betel nut. The betel nut stains the teeth a dark red/brown color and the constant chewing and spitting is also a clear sign. Betel nut can be found all over Asia, predominantly in areas occupied by hill tribes, but the more abrasive procedure of tooth lacquering is a tradition that only really remains in Vietnam. Mrs. Nguyen Thi Pham, a 67 year old Hanoian, dressed in a loose silk blouse, black satin trousers, a jade bracelet and necklace described the ritual blackening of her teeth when she was 17. Pham waves her slender gold-ringed fingers as she described the party-like atmosphere of the ceremony… Her grandmother blackened her teeth as the rest of her family looked on joking and making joyful comments to her as her mouth was being “painted.” There needed to be three applications (every other day for a week), because natural saliva washed off the original application of chemicals. For that period of time she could not eat solids and could drink only through a straw. The ritual certified that she was “grown up and ready for marriage.” Although it was not a painful process for Pham, I have spoken to other women who recall that their mouths swelled up or that their gums burned and stung for days. The procedure can take place sometime after the age of ten when the child has all her permanent teeth, but is usually done after menarche.

The chemical ingredients used to blacken the teeth can take several forms.

In Vietnam it is common to use red sticklac, a resin obtained from secretions of a tiny aphid-like insect that sucks the sap of a host tree, as a dye. The resin is diluted with lemon juice or rice alcohol and stored in the dark for a few days. It’s then applied with pressure to all the teeth. An application of iron (mainly from iron nails) or copper from green or black alum and tannin from Chinese gall reacts with solution to give a blue-black insoluble coating. In other areas of Southeast Asia coconut husk is burned to form a black sticky char that is then combined with nail filings and adhered to the tooth surface until the dye “takes.” The traditional method once used by the Japanese was to make a mixture by soaking iron fillings in tea or sake. This liquid then turns black upon oxidation of the iron. Spices like cinnamon, cloves and anise were often added to the resin to reduce the harsh chemical taste of the dye. As with most Asian traditions, there are long standing cultural reasons for tooth blackening. It was believed that only savages, wild animals and demons had long white teeth. The filing and blackening of the teeth was also a popular procedure and assurance that one would not be mistaken for an evil spirit. In Japan tooth blackening was known as Ohagura. It was believed to enhance sex appeal in addition to maintaining healthy teeth. Linking tooth blackening to a prolonged set of teeth is not just a belief; studies have shown that those with blackened teeth maintain a full set of teeth for longer than those without lacquered teeth. Similar procedures of tooth blackening and filing were also performed by tribes from Indonesia and the Philippines. Back in 1938, a French survey found 80% of the countryside folk of Vietnam had blackened teeth. Medieval kings of Vietnam and other Southeast Asian countries also blackened their teeth.

The procedure has been quite popular throughout Asian history.

But when the French came to Vietnam, they did not appreciate the implied beauty and the procedure was discouraged. Since then the numbers of Vietnamese dropped drastically, but in these modern times the traditional people of Vietnam are once again trying to revive an almost lost tradition.
