A new walking trend known as “Japanese walking” is making waves online, with fitness experts highlighting its effectiveness in promoting weight loss, heart health, and overall well-being. Although the technique is rooted in research from Japan, the workout—also known as interval walking—is gaining international attention thanks to a surge of interest on social media platforms like TikTok.
Japanese walking involves alternating between three minutes of high-intensity walking and three minutes at a slower pace, repeated for at least 30 minutes per session, four times a week. Fitness specialists say the method is gaining popularity because it’s accessible, time-efficient, and adaptable to various fitness levels.
“Exercise matters, and intensity matters,” said Laura Richardson, clinical associate professor of kinesiology at the University of Michigan. “This style of walking is sustainable, doesn’t require a gym, and offers measurable health benefits.”
The workout is built on the principles of interval training—a method that alternates between bursts of effort and periods of recovery, helping improve cardiovascular fitness and overall stamina. “You’re increasing blood flow and challenging your heart and lungs,” said Richardson. “Those are the conditions where positive physical changes happen.”
According to Rashelle Hoffman, a walking expert at Creighton University, high-intensity intervals give people “more bang for their buck” by delivering results with less time spent exercising. “We’re stressing the body more during those intervals, and the response is stronger,” she explained.
The appeal also lies in its simplicity. Unlike many fitness trends, Japanese walking doesn’t require any special equipment or prior training, making it an ideal option for people of all ages, including older adults or those new to exercise.
In one influential study led by Shizue Masuki of Shinshu University in Japan, researchers initially asked 246 older adults to walk briskly for 30 minutes a day. Most quit, saying it was too monotonous. When the program was switched to interval walking, participation improved dramatically—and so did the results. Participants showed increased leg strength, better cardiovascular fitness, reduced blood pressure, and improved cholesterol and fat levels. Further studies also linked interval walking to enhanced cognitive function and better sleep.
For some, like Indianapolis resident Emily Mendez, the variation makes walking more engaging. “The fast intervals feel like an achievement, and the slower ones feel like a reward,” she said. “It keeps me motivated.”
Experts recommend that those trying the workout start with a brisk pace that challenges them without pushing too far. While some use smartwatches to track intensity, a simpler gauge is how easy it is to talk during the workout—if you’re slightly breathless but still able to speak, you’re likely at the right level.
With its mix of structure, simplicity, and results, Japanese walking could prove to be more than a fleeting trend—offering an effective and inclusive path to better health.
