In 2026, one of the most surprising global fitness trends is “Japanese walking.” The name sounds simple, but it refers to a research-based method called Interval Walking Training, developed by Hiroshi Nose and Shizue Masuki at Shinshu University in Matsumoto, Japan. The pattern is easy to remember: walk briskly for three minutes, then walk gently for three minutes, and repeat. Shinshu University explains that the fast parts should be done at 70% or more of a person’s peak aerobic capacity, while the easy parts are around 40%. (shinshu-u.ac.jp)
Why is it spreading now? Part of the answer is timing. PureGym’s 2025/26 fitness report says “Japanese walking” is expected to be the fastest-growing fitness trend of 2026, with a 2,968% rise in interest. Strava’s 2025 Year in Sport report shows a wider change in exercise habits: the company says it has more than 180 million users in over 185 countries, and walking became the second most-recorded activity on the platform in 2025. In other words, the world is already walking more, and this Japanese method gives people a clear structure. (puregym.com)
The science behind the boom is strong. In a 2007 Mayo Clinic Proceedings study of 246 adults aged 44 to 78, the interval-walking group improved aerobic capacity and thigh muscle strength more than the group that did steady moderate walking, and they also had a larger drop in resting systolic blood pressure. A later study of 679 middle-aged and older adults found that after five months of interval walking, estimated peak aerobic capacity rose by 14% on average and lifestyle-related disease scores fell by 17%. The researchers also found that the benefits increased as weekly fast-walking time increased, up to about 50 minutes. (sciencedirect.com)
That combination of science and simplicity helps explain the trend. As search interest keeps rising and walking grows on global fitness platforms, a training idea from Japan is being rediscovered by people far beyond Japan. In a fitness culture often filled with expensive gear and extreme workouts, “Japanese walking” offers something refreshingly small and realistic: just six minutes, repeated again and again.
