Japan is often said to have the longest life expectancy. People live to be an average of 84 years old. Many people say this is because of a healthy diet. Another reason could be that Japanese people walk a lot. This has started a new fitness trend on TikTok, called "Japanese Walking". This is walking quickly for three minutes and then slowly for three minutes. Walkers repeat this pattern five times. Experts say Japanese walking is good for posture, lowering blood pressure, and reducing stress. It has also been linked to a lower risk of dementia. Doctors also say it can help people live longer.

Japanese people might not know about the term "Japanese Walking". Researchers at Shinshu University came up with the name in 2007. They conducted a study on fast and slow walking. The method is now popular worldwide. This is due to videos made by an Australian fitness coach and social media content creator. He wanted people to follow a simple exercise routine that had an easy-to-remember name. His videos have had 10 million views on TikTok. He said he wanted "to make fitness advice and scientific jargon a lot more accessible".
