Japanese walking is everywhere. But does it actually work?
If your social media feed has recently decided that three minutes of fast walking followed by three minutes of slow walking is the answer to all your health problems, welcome to the Japanese walking trend.
The name is new. The method isn’t.
Known in research as Interval Walking Training (IWT), this approach has been studied for years, particularly in middle-aged and older adults. So what happens when a perfectly reasonable exercise method gets picked up by TikTok? Let’s separate the useful science from the usual internet promises.
What is Japanese walking?
Japanese walking is a form of interval walking where you alternate between periods of brisk walking and easier recovery walking.
The commonly promoted version looks like this:
- 3 minutes brisk walking
- 3 minutes easy walking
- Repeat for around 30 minutes
- Aim for around 4 sessions per week
The original research protocol was more specific than simply “walk fast, then slow.” Participants were asked to alternate three-minute periods of easier walking at around 40% of their peak aerobic capacity with three-minute periods of faster walking at 70% or more of peak aerobic capacity. They were generally asked to complete at least five sets, four or more days per week.
You don’t need to know your exact aerobic capacity to try the concept.
The fast intervals should feel clearly more demanding than your normal walking pace. You should be breathing harder, but still be in control.
You shouldn’t be sprinting. But you shouldn’t be window-shopping either.
Why has Japanese walking suddenly become a trend?
This is where things get interesting.
Interval Walking Training has been around since the 2000s, with research from Shinshu University in Japan. The method became popular online after being repackaged into the much catchier name “Japanese walking.”
And in 2026, the trend really did take off. PureGym’s annual fitness report found that global Google search interest in “Japanese walking” had increased by almost 3,000% compared with the previous year, making it its fastest-growing fitness trend.
And honestly, it’s easy to see why.
It requires:
- No gym membership
- No complicated equipment
- No running
- No counting 10,000 steps
- No hour-long workout
- No pretending you enjoy burpees
For women in midlife who already have enough demands competing for their attention, that simplicity is appealing.
Does Japanese walking actually work?
This is the good bit.
There is legitimate research behind interval walking training, although the evidence relates to structured IWT protocols rather than every version of “Japanese walking” appearing on social media.
A 2007 randomised controlled trial involving 246 healthy middle-aged and older adults found that five months of high-intensity interval walking produced greater improvements in aerobic capacity and thigh muscle strength than moderate continuous walking. The interval group also had a greater reduction in resting systolic blood pressure.
Research in sedentary middle-aged adults has also found that three months of interval walking improved peak aerobic capacity and reduced resting systolic blood pressure.
Longer-term research has similarly linked IWT with improvements in aerobic fitness and several health-related measures.
So yes, there is something behind the trend.
But let’s not turn that into “Japanese walking will transform your body in 30 days.”
That part belongs firmly in the internet’s overpromising department.
Japanese walking and perimenopause: why it may be useful
This is where the trend becomes relevant for women in their 40s.
During perimenopause, maintaining cardiovascular fitness and muscle strength is important for overall health. Regular aerobic activity can support cardiovascular health, while resistance training is particularly useful for maintaining and building muscle.
Interval walking gives you a way to make walking more physically demanding without needing to run or use a gym.
There isn’t currently good evidence showing that Japanese walking has unique benefits specifically for women in perimenopause. Its potential usefulness comes from the benefits of aerobic exercise and from the fact that it is a relatively accessible way to introduce higher-intensity walking.
It can support cardiovascular fitness
Research on interval walking has found improvements in aerobic capacity, an important measure of cardiorespiratory fitness.
And you don’t need to become a runner to improve your fitness.
It can challenge your legs
The faster intervals require more effort from your lower body than an easy walk.
Research into IWT has found improvements in knee extension and flexion strength alongside improvements in aerobic fitness.
That doesn’t mean walking replaces strength training. It means your walk can provide more of a physical challenge than a completely easy stroll.
It can complement strength training
This is important.
Japanese walking isn’t a replacement for resistance training.
If you’re trying to maintain or build muscle during perimenopause, think of interval walking as cardiovascular training that sits alongside strength training, rather than instead of it.
What about weight loss?
Here’s where I’d be careful.
Japanese walking can increase the intensity of your walking and may increase energy expenditure compared with an easier pace. Exercise is also important for cardiovascular and metabolic health.
But it shouldn’t be sold as a magic weight-loss hack.
Your body does not suddenly become a fat-burning machine because you changed walking speed every three minutes.
And for women who have spent decades being told that every form of movement needs to be used to shrink their bodies, I’d much rather see this framed around fitness, strength, cardiovascular health and quality of life.
Weight loss can happen with many different interventions. It doesn’t need to be the reason you move your body.
How to try Japanese walking
You don’t have to jump straight into the full research protocol.
If you’re currently doing very little structured exercise, start where you are.
Beginner version
Try:
- 5 minutes easy walking to warm up
- 1 minute brisk walking
- 2 minutes easy walking
- Repeat 5 times
- 5 minutes easy walking to finish
As your fitness improves, you can gradually move towards the traditional 3-minute brisk, 3-minute easy intervals.
The brisk pace should feel challenging, but controlled.
Think “I could answer a question, but I’d rather not give a TED Talk right now.”
Do you need to walk for exactly 30 minutes?
No.
This is another place where social media tends to turn a useful protocol into a rigid rule.
The research protocol used repeated three-minute intervals and was performed regularly over several months.
But if you currently have 15 minutes, 15 minutes is considerably more useful than waiting for the perfect 30-minute window that never arrives.
You can also build up gradually.
Consistency matters.
Is Japanese walking suitable for everyone?
Not necessarily.
The faster intervals are more demanding than ordinary walking. If you have a medical condition that affects your ability to exercise, significant mobility or balance problems, or you are returning to exercise after a long period of inactivity, speak with your healthcare professional about an appropriate starting intensity.
And if brisk walking causes pain, dizziness, chest pain or unusual shortness of breath, stop and seek appropriate medical advice rather than trying to push through it.
More intensity isn’t automatically better. Appropriate intensity is better.
Japanese walking vs a regular walk
So which one should you choose?
Honestly, the one you’ll actually do.
A relaxed walk is still physical activity. You don’t need to turn every stroll into a training session.
Japanese walking becomes interesting when you want to deliberately challenge your cardiovascular fitness but don’t particularly want to run, use a gym, or spend an hour exercising.
Think of it as another tool in your exercise toolbox, not the newest rule you have to follow.
The biggest mistake people make with Japanese walking
Turning it into another “perfect exercise” challenge.
You don’t need to complete it four times every week for it to count.
You don’t need the perfect pace.
You don’t need a smartwatch.
And you certainly don’t need to feel guilty if today’s walk was simply a walk.
For women navigating perimenopause, exercise should support your life, not become another thing you’re failing at.
Exercise warning:Â If you have a medical condition, significant pain, balance problems, or symptoms such as chest pain, dizziness or unusual shortness of breath during exercise, seek appropriate medical advice before increasing exercise intensity.
The bottom line
Japanese walking isn’t a revolutionary new exercise.
It’s a catchy name for interval walking training, a method that has been studied for many years and has evidence supporting improvements in aerobic fitness, leg strength and blood pressure.
For women in perimenopause, it can be a useful way to add cardiovascular challenge to your routine without taking up hours of your week.
But you don’t need to turn it into another weight-loss project.
Walk because you want a stronger heart, stronger legs, better fitness and a body that can keep doing the things you enjoy.
And if Japanese walking makes that a little more enjoyable? Even better.
