History of Manpokei

Although the pedometer was first invented in Europe, we began manufacture and sale of Manpokei in 1965, which continues to this day. Manpokei, which has become synonymous with pedometers in Japan, is a registered trademark of Yamasa Tokei Keiki Co., Ltd. Most pedometers exported overseas are of Japanese origin. In particular, Japanese products are trusted in developed countries in Europe, North America, and Australia, which value high precision.


The reason Manpokei is used for health promotion

Walking is good for your health, and in order to burn 300 kilocalories in a day through exercise, it is recommended that you walk approximately 10,000 steps. By wearing a Manpokei, you can find out how many steps you have taken each day, and use that information to maintain your health. In addition, Manpokei is an ideal product for medical research. It is used around the world, not just in developed countries, by researchers in the fields of health and medicine, as well as at universities.



In addition to the traditional Manpokei that is attached to the hip, new designs of Manpokei have been well received over the last several years, including models that are fitted with a 3D sensor and can easily take measurements even when carried in your pocket or bag, activity meters that measure the total calories burned during the day through tasks such as deskwork and housework, and models that are incorporated into wristwatches (atomic watches). There are a range of colors and designs to choose from, with products to suit men and women of all ages.
