Japanese Walking: What It Is, Does It Work, and a 4-Week Plan to Start

Japanese walking is the viral name for interval walking training, a method developed by researchers at Shinshu University in Japan. You walk fast for 3 minutes, then slowly for 3 minutes, and repeat that five times for about 30 minutes, on at least 4 days a week. In the original trial, people who walked this way for 5 months gained more leg strength and aerobic fitness, and saw a bigger fall in blood pressure, than people who walked at a steady moderate pace.

The key insight: the benefit comes from the fast intervals, not the total distance. Short spells of genuinely hard walking appear to do more than a longer, comfortable stroll, which makes it a good fit for anyone who wants more from the time they already spend walking.

Below: the research, its limits, how to judge the fast pace, and a 4-week plan.

What Is Japanese Walking?

The method was developed by Professor Hiroshi Nose and Dr Shizue Masuki at Shinshu University. They wanted exercise that middle-aged and older adults could do without a gym to slow the age-related loss of fitness and thigh strength.

The structure is simple:

• 3 minutes of fast walking, at roughly 70% or more of your peak walking capacity
• 3 minutes of slow walking, at roughly 40%
• 5 or more rounds, so about 30 minutes in total
• 4 or more days a week

Researchers call it interval walking training (IWT). "Japanese walking" is the social media name.

What the Research Shows

The Original Trial

The founding study was a randomised trial by Nemoto and colleagues, published in Mayo Clinic Proceedings in 2007. It followed 246 adults with an average age of 63 for 5 months. They were split into three groups: no walking training, continuous walking at a moderate pace (aiming for at least 8,000 steps a day), and interval walking.

In the interval group, knee extension strength rose by 13%, knee flexion strength by 17%, and peak walking capacity by 9%. These gains were significantly greater than in the moderate continuous group. The interval walkers also had a larger drop in resting systolic blood pressure. The authors concluded that interval walking may protect against age-related rises in blood pressure and declines in thigh strength and aerobic capacity.

Not everyone hit their targets: 11 of 19 men and 31 of 68 women in the interval group did the full prescribed training, so it is not effortless.

Larger Field Studies

A 2009 review in The Journal of Physiology by Nose and colleagues describes a community programme in which 783 of 826 people (95%) completed 4 months. Among the 666 analysed, average age about 65, peak walking capacity rose by around 15% and a lifestyle-related disease risk score fell.

Independent Research

A group in Denmark tested the method in people with type 2 diabetes. Their 2013 randomised trial in Diabetes Care compared interval walking with continuous walking that used the same amount of energy. Over 4 months, the interval group improved aerobic fitness by about 16% and lost an average of 3.1kg of fat mass, while the continuous group showed no change in either. Some measures of blood glucose improved in the interval group, though HbA1c did not change significantly.

What It Does Not Show

• Much of the evidence comes from one research group, the team that created the method. The independent trials are encouraging but small; the Danish study analysed 12 people per training group.
• Most participants were middle-aged or older. People who already run or train hard are unlikely to see the same gains.
• It is not a weight loss method on its own. Diet matters far more for body weight.
• It does not replace strength training. Leg strength improved, but walking does not train the upper body or load the muscles the way resistance work does.

Japanese Walking vs 10,000 Steps

The 10,000 steps target is a round number rather than a research finding. A 2022 meta-analysis in The Lancet Public Health, pooling data from 15 studies and over 47,000 adults, found that more daily steps were linked to a progressively lower risk of death, but the benefit levelled off at around 6,000 to 8,000 steps a day for adults over 60, and 8,000 to 10,000 for younger adults.

Step counts measure how much you move; interval walking focuses on how hard you move for part of that time. In the original trial, the group aiming for 8,000 steps at a moderate pace improved less than the interval group. The two work well together: a daily step habit, plus interval sessions several days a week.

Who Japanese Walking Suits

• Beginners who find running daunting and want a clear structure
• People returning to exercise after a break, injury or a busy spell (our guide to the best platforms for returning to training covers how to rebuild sensibly)
• Older adults who want to protect leg strength and fitness
• Anyone wanting low-impact cardio as the weather turns. It works on a treadmill or walking pad too: raise the speed or incline for 3 minutes, then drop it for 3

If you have a heart or lung condition, joint problems, high blood pressure, diabetes, are pregnant, take regular medication, or notice chest pain, dizziness or unusual breathlessness when you exercise, speak to your GP before starting.

How Fast Is the Fast Pace?

The research set the fast phase at about 70% of peak walking capacity, measured in a lab. Without a lab:

• Slow phase: a relaxed pace where you could hold a full conversation.
• Fast phase: noticeably harder than your normal brisk walk. Your breathing is quicker, you can still speak in short sentences, but you could not sing. The NHS uses this same talk but not sing test to describe moderate intensity, and in the fast phase you should be at the top end of it.
• Effort scale: on a 1 to 10 scale, aim for around 6 to 7 in the fast phase and 3 to 4 in the slow phase.

A quicker arm swing or a hill raises the effort without jogging.

A 4-Week Plan to Start Japanese Walking

This plan builds gradually to the full protocol. Warm up and cool down with a few minutes of easy walking.

A few tips to make it stick:

• Use a repeating interval timer so you are not checking the clock.
• Progress with effort, not just time. Once week 4 feels manageable, make the fast phase a little quicker or add a hill, in the spirit of progressive overload.
• Repeat a week if you need to.

Pairing Japanese Walking With Strength Training

The NHS guidelines recommend at least 150 minutes of moderate activity a week plus strengthening activities for all major muscle groups on at least 2 days. Four interval walks cover most of the first target; the second needs separate work.

A simple week: interval walks on Monday, Wednesday, Saturday and Sunday, and strength sessions (squats, lunges, push-ups, rows, a plank) on Tuesday and Friday, with Thursday as rest or an easy walk.

For women in their 40s and 50s, strength work matters even more, and our guide to strength training in perimenopause explains where to begin.

How Visionary Can Help

Visionary builds personalised training plans around the time you have, so interval walks can sit alongside two strength sessions. If a week gets busy, ask Vic, the AI coach, how to adjust. Sleep and cycle tracking in the same app help explain why some sessions feel harder.

You can start a free trial of Visionary and build a plan that includes walking you will actually keep doing.

FAQ

What is the Japanese walking method?

It is interval walking training from Shinshu University in Japan: 3 minutes fast, 3 minutes slow, 5 rounds, on at least 4 days a week. Each session takes about 30 minutes.

Does Japanese walking actually work?

In a 2007 randomised trial, interval walkers gained more thigh strength, aerobic capacity and blood pressure benefit than steady moderate walkers. Most research comes from the team that created it, mainly in middle-aged and older adults.

Is Japanese walking better than 10,000 steps?

They measure different things. In the original trial, interval walking improved fitness more than aiming for 8,000 moderate steps a day, so doing both is sensible.

Can you do Japanese walking on a treadmill or walking pad?

Yes. Raise the speed or incline for the fast phase, then lower it for the slow phase. Walking pads often have a low top speed, so incline or a quicker arm swing helps.

How fast should you walk in Japanese walking?

Noticeably harder than a normal brisk walk: you can talk in short sentences but not sing, about 6 to 7 out of 10. The slow phase should allow a full conversation.

Can Japanese walking help you lose weight?

One small trial found fat loss in people with type 2 diabetes, but on its own it is unlikely to change body weight much. Food intake, strength training and sleep matter more.
