In Japanese, toothpaste is actually called hamigakiko, "tooth-cleaning powder," and such powders have been used in Japan since the Edo period (17th-19th century). They still exist since, according to hardcore traditionalists, they offer a healthier and more effective alternative to modern toothpaste, especially when it comes to whitening the teeth. Not convinced? Try the two different types of hamigakiko in the Chojiya Kizaemon Ohakuro Ohashiro Dental Care Set and you will be!
Both boxes in the Chojiya Kizaemon Ohakuro Ohashiro Dental Care Set contain 20 grams (0.7 ounces) of tooth-cleaning powder whose main ingredient is a material called apatite that comes from egg shells. Thanks to its high level of calcium, apatite makes this powder stronger than regular toothpaste and the results are visible in both the appearance and the health of your teeth. And to make things even more traditional, the Ohakuro box contains black powder so when you are brushing your teeth you'll look like a medieval Japanese aristocrat: black teeth were all the rage back in the day!
