What Is Japanese Walking, Exactly?

Search interest in "Japanese walking" grew by 2,986% between 2024 and 2025, making it one of the fastest-rising fitness trends going into 2026. If you haven't heard of it yet, you probably will soon.

Japanese walking — properly called Interval Walking Training or IWT — is a structured walking method that alternates between three minutes of brisk, fast-paced walking and three minutes of slower, recovery-pace walking. You repeat the cycle five times for a 30-minute session. That's the whole workout.

It was developed by researchers at Shinshu University in Japan, led by Professor Hiroshi Nose and Associate Professor Shizue Masuki, who set out to study how middle-aged and older adults could improve their fitness without high-impact exercise. The original research dates to the early 2000s, but it's taken two decades to reach mainstream Western audiences — largely thanks to social media and fitness content creators discovering and sharing it.

How to Do Japanese Walking

The method is refreshingly simple. No equipment, no gym, no tracking app required (though one helps).

The slow phase (3 minutes): Walk at a comfortable, easy pace — roughly 40% of your maximum effort. You should be able to hold a conversation easily. This is your recovery phase, not your rest phase. Keep moving.

The fast phase (3 minutes): Walk at a brisk, purposeful pace — roughly 70% of your maximum effort. You should feel your breathing deepen and your heart rate rise. You can still speak in short sentences, but a long conversation would be difficult. This is genuinely faster than you'd naturally choose to walk.

Repeat 5 times: That's 5 slow phases and 5 fast phases — 30 minutes total. Ideally do this 4 times per week.

A smartphone fitness app with interval timers works well. The free Interval Timer app (iOS and Android) can be set to alternate 3-minute periods and will buzz on your wrist if you wear a smartwatch. Or just set a repeating phone alarm every 3 minutes for 30 minutes.

What the Research Actually Shows

The Shinshu University research team studied 679 middle-aged and older adults over five months. Participants who did interval walking training improved their aerobic fitness (VO2 max — a gold-standard cardiovascular health marker) significantly more than those who walked at a constant pace. Their blood pressure improved. Their overall indices of lifestyle-related diseases improved by an average of 10-20%.

A 2025 study found additional benefits for people with type 2 diabetes, with participants showing improved glycaemic control after regularly practising IWT. The Brown University Health page on IWT summarises the evidence plainly: "Interval walking training has been shown to be more effective than continuous walking for improving physical fitness, reducing blood pressure, and improving blood sugar control."

Why It Works Better Than Regular Walking

The reason regular walking (even lots of it) has limited fitness benefits over time is adaptation. Your body gets efficient at a steady pace and stops being challenged. Intervals disrupt that adaptation by repeatedly asking your cardiovascular system to work harder, then recover — the same principle behind HIIT, but at a joint-friendly, accessible intensity.

And unlike running or true HIIT, Japanese walking keeps one foot on the ground at all times. There's no impact. This makes it suitable for people who are overweight, older, managing joint issues, or simply returning to exercise after a break. The barrier to starting is extremely low.

Who Japanese Walking Is For

Pretty much everyone — but it's particularly well-suited to people who already walk regularly and aren't seeing much change, older adults looking to improve cardiovascular health without high-impact exercise, people managing type 2 diabetes or pre-diabetes, and anyone who finds the gym intimidating or inaccessible.

If you're already a regular runner or doing structured cardio training, Japanese walking won't replace your existing programme — but it's an excellent active recovery option on rest days.

FAQ

Is Japanese walking the same as power walking?

Not quite. Power walking is sustained fast walking at a constant pace. Japanese walking alternates between fast and slow, which creates the interval-training effect that drives its fitness benefits.

How many calories does Japanese walking burn?

More than regular walking, less than running. A rough estimate for a 70kg person is 200-280 calories per 30-minute IWT session, compared to 100-150 for the same duration of steady-pace walking. But the cardiovascular and metabolic benefits are arguably more important than the calorie number.

Can I do Japanese walking on a treadmill?

Yes. Adjust the speed rather than the incline for the fast/slow phases. Most treadmills let you set interval programmes. 3.5-4.5 mph for slow phases and 5-6 mph for fast phases is a reasonable starting range, adjusting to your fitness level.

How soon will I notice results?

The Shinshu University research used a five-month protocol, but most participants reported improved energy and reduced breathlessness during everyday activity within 4-6 weeks of starting.
